    Full Text Available Abstract Background Health impacts of poor environmental quality have been identified in studies around the world and in Canada. While many of the studies have identified associations between air pollution and mortality or morbidity, few have focused on the role of health care as a potential moderator of impacts. This study assessed the determinants of health care access and utilization in the context of ambient air pollution in Sarnia, Ontario, Canada. Methods Residents of Sarnia participated in a Community Health Study administered by phone, while several ambient air pollutants including nitrogen dioxide (NO2, sulphur dioxide (SO2 and the volatile organic compounds benzene, toluene, ethylbenzene, mp- and o-xylene (BTEX were monitored across the city. Land Use Regression models were used to estimate individual exposures to the measured pollutants and logistic regression models were utilized to assess the relative influence of environmental, socioeconomic and health related covariates on general practitioner access and utilization outcomes. Results The results show that general practitioner use increased with levels of exposure to nitrogen dioxide (NO2- Odds Ratio [OR]: 1.16, p 2- OR: 1.61, p 2 and SO2. Respondents without regular care living in high pollution areas were also more likely to report travelling or waiting for care in excess of 20 minutes (OR: 3.28, p p > 0.05. Conclusions This study provides evidence for inequitable health care access and utilization in Sarnia, with particular relevance to its situation as a sentinel high exposure environment. Levels of exposure to pollution appears to influence utilization of health care services, but poor access to primary health care services additionally burden certain groups in Sarnia, Ontario, Canada.

  4. Assessing the distribution of volatile organic compounds using land use regression in Sarnia, "Chemical Valley", Ontario, Canada

    2009-04-01

    Full Text Available Abstract Background Land use regression (LUR modelling is proposed as a promising approach to meet some of the challenges of assessing the intra-urban spatial variability of ambient air pollutants in urban and industrial settings. However, most of the LUR models to date have focused on nitrogen oxides and particulate matter. This study aimed at developing LUR models to predict BTEX (benzene, toluene, ethylbenzene, m/p-xylene and o-xylene concentrations in Sarnia, 'Chemical Valley', Ontario, and model the intra-urban variability of BTEX compounds in the city for a community health study. Method Using Organic Vapour Monitors, pollutants were monitored at 39 locations across the city of Sarnia for 2 weeks in October 2005. LUR models were developed to generate predictor variables that best estimate BTEX concentrations. Results Industrial area, dwelling counts, and highways adequately explained most of the variability of BTEX concentrations (R2: 0.78 – 0.81. Correlations between measured BTEX compounds were high (> 0.75. Although most of the predictor variables (e.g. land use were similar in all the models, their individual contributions to the models were different. Conclusion Yielding potentially different health effects than nitrogen oxides and particulate matter, modelling other air pollutants is essential for a better understanding of the link between air pollution and health. The LUR models developed in these analyses will be used for estimating outdoor exposure to BTEX for a larger community health study aimed at examining the determinants of health in Sarnia.

    1995-01-01

    A study was conducted to examine ways in which the oil refiners and petrochemical producers in the Sarnia Complex in Ontario could become more competitive with their counterparts in the United States through joint actions. Methods by which the petroleum industry could meet the challenges posed by changing environmental regulations were proposed. Five suggestions were advanced, i. e., (1) increase pipeline capacity and reduce refining and petrochemical feedstock shipping costs to Ontario, (2) joint ventures in existing or new facilities to produce higher value products, mainly petrochemicals, (3) major joint process integrations involving investment in significant new facilities to meet demand growth and maximize value of the product slate, (4) major joint process integrations to manufacture cleaner fuels, and (5) joint services and utilities integration. Of the joint actions identified by experts, those which were judged to be most plausible and had the greatest profit potential were: further cogeneration, distillate desulfurization, hydrogen production and pipelining, cryogenic recovery of light ends, styrene production and sharing services and utilities.68 refs., 7 tabs., 9 figs

  7. Smoke and mirrors: used oil management policy in Ontario

    International Nuclear Information System (INIS)

    Valiante, U.

    1997-01-01

    The burning of used oil for space heating is a practice that has been increasing since 1992 when the waste fuel regulation was amended to give northern generators without access to used oil collection an option for managing their used oil. In 1996, about 10 million litres of used oil was burned in Ontario at over 600 locations, in garages, automotive repair facilities, industrial locations and greenhouses. The modified space heaters that burn used motor oils operate without pollution controls. In addition to emissions associated with pollution from uncontrolled combustion, used oil fired space heaters burn what should be a reusable commodity that is high in value added chemical and energy content. A comparison of emissions in grams per 1000 hours of use of a used oil heater and a natural gas heater was presented. It was suggested that as the preferred environmental strategy, the Ontario government should encourage used oil collectors and re-refiners to make used oil management convenient, accessible, and cost-effective in order to protect the health of communities in which used oil is generated

    2006-01-01

    Sarnia-Lambton Economic Partnership has embarked upon a novel path toward building a hydrogen cluster. Without an indigenous 'technology' star, the foundation for the cluster is the petrochemical industry and the broad spectrum of local enterprises and institutions that supply it. Hydrogen is both a by-product and feedstock for different applications in the region, resulting in the development of a large pipeline network to connect waste gas to consumers. The local capabilities developed to process, deliver and maintain this system have helped to attract new industries that require hydrogen to the area. The same capabilities are now being leveraged from chemical applications to energy applications for hydrogen. The H 2 D Project will assemble the largest fleet of hydrogen fuelled 'appliances' in North America, with 200 devices including on and off-road vehicles, and portable and stationary hydrogen applications utilizing a wide array of technologies. H 2 D is a community driven project that leverages and supports educational programs at Lambton College and the University of Western Ontario (key elements of a thriving industrial cluster), sophisticated local safety services, and support from local, provincial and federal governments, to provide a testing ground for technology providers and local suppliers in an environment with a 'gas' savvy population and supporting infrastructure.

  10. Impact of air pollution on hospital admissions in Southwestern Ontario, Canada: Generating hypotheses in sentinel high-exposure places

    Directory of Open Access Journals (Sweden)

    Luginaah Isaac N

    2007-07-01

    Full Text Available Abstract Background Southwestern Ontario (SWO in Canada has been known as a 'hot spot' in terms of environmental exposure and potential effects. We chose to study 3 major cities in SWO in this paper. We compared age-standardized hospital admission ratios of Sarnia and Windsor to London, and to generate hypotheses about potential pollutant-induced health effects in the 'Chemical Valley', Sarnia. Methods The number of daily hospital admissions was obtained from all hospitals in London, Windsor and Sarnia from January 1, 1996 to December 31, 2000. We used indirect age adjustment method to obtain standardized admissions ratios for males and females and we chose London as the reference population. This process of adjustment was to apply the age-specific admission rates of London to the population of Sarnia and Windsor in order to yield expected admissions. The observed number of admissions was then compared to the expected admissions in terms of a ratio. These standardized admissions ratios and their corresponding confidence intervals were calculated for Sarnia and Windsor. Results Our findings showed that Sarnia and Windsor had significantly higher age-adjusted hospital admissions rates compared to London. This finding was true for all admissions, and especially pronounced for cardiovascular and respiratory admissions. For example, in 1996, the observed number of admissions in Sarnia was 3.11 (CI: 2.80, 3.44 times for females and 2.83 (CI: 2.54, 3.14 times for males as would be expected by using London's admission rates. Conclusion Since hospital admissions rates were significantly higher in 'Chemical Valley' as compared to both London and Windsor, we hypothesize that these higher rates are pollution related. A critical look at the way ambient air quality and other pollutants are monitored in this area is warranted. Further epidemiological research is needed to verify our preliminary indications of harmful effects in people living in 'Chemical

  11. Ontario energy review

    International Nuclear Information System (INIS)

    1990-03-01

    This publication provides a review of the developments in Ontario in relation to the national and international energy scene. Ontario is the largest energy consumer in Canada and is highly dependent on external energy sources. Several developments have significantly altered the Ontario energy scene. Oil and gas markets have become deregulated and market forces increasingly determine prices. A free trade agreement with the United States makes Ontario even more affected by international markets. Oil and gas prices have fallen from the high levels of the 1980s, but energy efficiency and conservation continue to be extremely important because they affect economic performance and the environment. In the next few years the greatest challenges will be to continue improving energy efficiency, to reduce the impact of energy on the environment, and to ensure the availability of sufficient energy supplies for future needs. This review contains statistics on energy in Ontario and explains them for the non-specialist. (7 tabs., figs.)

  12. Hard oiler : the story of early Canadian's quest for oil at home and abroad

    International Nuclear Information System (INIS)

    May, G.

    1998-05-01

    The story of how the petroleum industry in Canada took root is described. The book retells the discovery and the quest for oil in the Sarnia area in 1858 when James Miller Williams and Charles Nelson Tripp struck oil at what was to be the world's first modern commercial petroleum operation. This set in motion a chain of events which resulted in the establishment of an industry on which life today is so heavily dependent. The circumstances that led to the discovery of petroleum in the midst of southwestern Ontario's last wilderness are described with special emphasis on the men and the women who were responsible for it. The book chronicles the role they played and the equipment they devised that led to a frenzy of land speculation, as well as to the training of a class of men who later introduced their expertise and equipment to new oil fields around the world to open up oil fields from Sumatra to the Ukraine, from the United States to Venezuela, and in the Middle East. In the latter part of the nineteenth and the early twentieth centuries no major oil field anywhere in the world was without its drillers from Lambton county in southwestern Ontario - the Hard Oilers. The story begins with the early discoveries in the 1840s, carries on with the golden age of Ontario oil, describes the part played by the Lambton county oilmen in opening up oilfields in distant parts of the world, and ends with an assessment of the latest discovery of the Hibernia fields offshore Newfoundland. refs., figs

    2002-01-01

    On May 1, 2002 both wholesale and retail electricity markets in Ontario were opened to competition. Wholesale electricity market sales of 150 TWh were valued at over $11 billion with 27,500 MW in service installed capacity and 4,000 to 6,000 MW import/export capability with strong interconnections to the Quebec, the Midwest and the Northeast. The key players in Ontario's electricity market are the Ontario Energy Board (OEB), the Independent Electricity Market Operator (IMO), Ontario Power Generation, and Hydro One. The OEB regulatory framework includes licensing and front line, daily monitoring of whole sale market. Serious capacity problems in Ontario have manifested themselves in tight supply and demand situations and highly volatile prices. The paper included graphs of available reserves for 1996 to 2002, HOEP trends and frequency, HOEP comparison, and a sensitivity to demand forecast. 1 tab., 6 figs

  16. Evaluation of missing value methods for predicting ambient BTEX concentrations in two neighbouring cities in Southwestern Ontario Canada

    High density air monitoring campaigns provide spatial patterns of pollutant concentrations which are integral in exposure assessment. Such analysis can assist with the determination of links between air quality and health outcomes, however, problems due to missing data can threaten to compromise these studies. This research evaluates four methods; mean value imputation, inverse distance weighting (IDW), inter-species ratios, and regression, to address missing spatial concentration data ranging from one missing data point up to 50% missing data. BTEX (benzene, toluene, ethylbenzene, and xylenes) concentrations were measured in Windsor and Sarnia, Ontario in the fall of 2005. Concentrations and inter-species ratios were generally similar between the two cities. Benzene (B) was observed to be higher in Sarnia, whereas toluene (T) and the T/B ratios were higher in Windsor. Using these urban, industrialized cities as case studies, this research demonstrates that using inter-species ratios or regression of the data for which there is complete information, along with one measured concentration (i.e. benzene) to predict for missing concentrations (i.e. TEX) results in good agreement between predicted and measured values. In both cities, the general trend remains that best agreement is observed for the leave-one-out scenario, followed by 10% and 25% missing, and the least agreement for the 50% missing cases. In the absence of any known concentrations IDW can provide reasonable agreement between observed and estimated concentrations for the BTEX species, and was superior over mean value imputation which was not able to preserve the spatial trend. The proposed methods can be used to fill in missing data, while preserving the general characteristics and rank order of the data which are sufficient for epidemiologic studies.

  18. Cogeneration markets in Ontario

    International Nuclear Information System (INIS)

    Poredos, S.

    1993-01-01

    Cogeneration offers a key strategy which supports global competitiveness for Ontario businesses, encourages energy efficiency and environmental protection, and offers natural gas utilities and producers stable long-term incremental markets. By supporting cogeneration projects, electric utilities will benefit from increased flexibility. Natural gas is the fuel of choice for cogeneration, which can in most cases be easily integrated into existing operations. In Ontario, electric demand grew along with the gross domestic product until 1990, but has decreased with the recent economic recession. The provincial utility Ontario Hydro is resizing itself to stabilize total rate increases of 30% over the last three years and supporting reduction of its high debt load. Rate increases are supposed to be limited but this may be difficult to achieve without further cost-cutting measures. Cogeneration opportunities exist with many institutional and industrial customers who are trying to remain globally competitive by cutting operating costs. In general, cogeneration can save 20% or more of total annual energy costs. Due to excess capacity, Ontario Hydro is not willing to purchase electric power, thus only electric load displacement projects are valid at this time. This will reduce overall savings due to economies of scale. In southwestern Ontario, Union Gas Ltd. has been successful in developing 40 MW of electric displacement projects, providing a total load of 5 billion ft 3 of natural gas (50% of which is incremental). Over 3,000 MW of technical cogeneration potential is estimated to exist in the Union Gas franchise area

    Ontario Hydro currently operates 18 nuclear electric generating units of the CANDU design with a net capacity of 12,402 MW(e). An additional 1,762 MW(e) is under construction. The operation of these facilities has underlined the need to have decontamination capability both to reduce radiation fields, as well as to control and reduce contamination during component maintenance. This paper presents Ontario Hydro decontamination experience in two key areas - full heat transport decontamination to reduce system radiation fields, and component decontamination to reduce loose contamination particularly as practised in maintenance and decontamination centres.

  3. Retailers test Ontario market

    International Nuclear Information System (INIS)

    Kishewitsch, S.

    2000-01-01

    In anticipation of the full opening of the Ontario electricity market in November 2000, some of the newly-licensed electricity retailers are reported to be ready to begin testing the market early, hoping that all the uncertainties that still exist about pricing will be worked out in time. Among those jumping in now is Direct Energy Marketing, a retailer which claims 800,000 households in Ontario as electricity supply customers, as well as a wholesale gas marketing business. Direct Energy began retail electrical marketing on April 3, 2000, starting cautiously with small commercial operations as the initial target. Greengrid Electric, another of the new marketers, planned to begin marketing in mid-April, offering 100 per cent renewable-sourced electricity. Provident Energy Management, one of the new marketers whose licence is still pending, hopes to begin direct marketing as soon as its licence is confirmed. Another marketer ready to go as soon its license is issued is the former Sault Ste. Marie Hydro, now reorganized as PUC Energies Inc. PUC has the advantage of having a firm contract with a NUG (non-utility generator), Great Lakes Power, signed while PUC was still a municipal electric utility. As far as the other potential marketers are concerned, caution overrides opportunity for the present. Principal concerns are uncertainty over the retail settlement code, the electronic business data transfer system, transmission and distribution tariffs, whether existing non-utility generator contracts will allow for supply to another party, and over how quickly Ontario Power Generation Inc's (successor to Ontario Hydro) market power will be ratcheted down. Many of the potential marketers feel that despite the Ontario government's desire to see more competition, the power mitigation agreement, as it now reads, leaves little room for the small retailer to compete

    Runnalls, O.J.C.

    1981-01-01

    This report traces the Ontario uranium mining industry from the first discovery of uranium north of Sault Ste. Marie through the uranium boom of the 1950's when Elliot Lake and Bancroft were developed, the cutbacks of the 1960s, the renewed enthusiasm in exploration and development of the 1970s to the current position when continued production for the domestic market is assured. Ontario, with developed mines and operational expertise, will be in a position to compete for export markets as they reopen. The low level of expenditures for uranium exploration and the lack of new discoveries are noted. The report also reviews and places in perspective the development of policies and regulations governing the industry and the jurisdictional relationships of the Federal and Provincial governments

  5. Ontario's commitment to nuclear power

    International Nuclear Information System (INIS)

    Parkinson, E.A.

    1991-01-01

    The title of this paper, 'Ontario's commitment to nuclear power', is significant because, as a publicly-owned company, Ontario Hydro will not be committed to nuclear power unless the Ontario public is also committed to nuclear power. In developing our strategic plan for generating electricity over the next 25 years, public acceptance was the big issue that we had to face, and it will be the underlying theme throughout this paper. In Ontario uranium is an indigenous fuel, and that is one of the reasons why Ontario adopted nuclear power in the first place, because it provides energy security. The uranium business is important to Canada, and to Ontario where we are 50% dependent on nuclear power at the current time. (author)

  6. Ontario's petroleum legacy : the birth, evolution and challenges of a global industry

    International Nuclear Information System (INIS)

    Gray, E.

    2008-01-01

    This book provided a historical account of Ontario's role in the global oil industry, from the coming in of the first wells at Oil Springs in the mid-19th century when the primary fuel sources were wood, coal, and water. In 1858, oil seeps in Enniskillen Township, Lambton County, Ontario revealed the existence of petroleum, which encouraged the first drilling of wells and the development of the global industry. The book explored issues related to imperialism, resource development, local history and the colonial land policies surrounding the oil boom. Details of the Petrolia oil discovery were included along with the accomplishments of the entrepreneurs who were instrumental in developing the petroleum industry in Ontario. The major elements surrounding the development of Canada's oil and gas industry were presented, beginning with the coal-oil-refining industry which paved the way for the development of the oil industry; the early oilmen from Oil Springs and Petrolia who drilled for oil; the development of the oil and gas industry's position today as a major strength of the Canadian economy; and the environmental and climate change issues that currently confront the industry. After 150 years, the oil fields at Petrolia and Oil Springs still produce commercial quantities of crude oil from at least 650 active wells. refs., figs

    1986-04-01

    Ontario Hydro is a corporation without share capital created by a special statute of the Province of Ontario in 1906. It now operates under the authority of the Power Corporation Act, R.S.O. 1980, Chapter 384, as amended, with broad powers to generate, supply and deliver electric power throughout the province. It is also authorized to produce and sell steam and hot water as primary products. The Corporation's prime objective is to supply the people of Ontario with electricity at the lowest feasible cost consistent with high safety and quality of service standards. Ontario Hydro's main activity is wholesaling electric power to municipal utilities in urban areas who, in turn, retail it to customers in their service areas. In 1985, approximately 3,166,000 customers were served by Ontario Hydro and the municipal utilities in the province. Ontario Hydro operates 81 hydraulic, fossil and nuclear generating stations and an extensive power grid across Ontario to meet the province's demands for electric energy. Interconnections with other systems place the Corporation in an extensive electrical grid that covers a large segment of the North American continent. Ontario Hydro is a financially self-sustaining corporation. The Province of Ontario guarantees bonds and notes issued to the public by the Corporation

  8. Ontario demand response scenarios

    International Nuclear Information System (INIS)

    Rowlands, I.H.

    2005-09-01

    Strategies for demand management in Ontario were examined via 2 scenarios for a commercial/institutional building with a normal summertime peak load of 300 kW between 14:00 and 18:00 during a period of high electricity demand and high electricity prices. The first scenario involved the deployment of a 150 kW on-site generator fuelled by either diesel or natural gas. The second scenario involved curtailing load by 60 kW during the same periods. Costs and benefits of both scenarios were evaluated for 3 groups: consumers, system operators and society. Benefits included electricity cost savings, deferred transmission capacity development, lower system prices for electricity, as well as environmental changes, economic development, and a greater sense of corporate social responsibility. It was noted that while significant benefits were observed for all 3 groups, they were not substantial enough to encourage action, as the savings arising from deferred generation capacity development do not accrue to individual players. The largest potential benefit was identified as lower prices, spread across all users of electricity in Ontario. It was recommended that representative bodies cooperate so that the system-wide benefits can be reaped. It was noted that if 10 municipal utilities were able to have 250 commercial or institutional customers engaged in distributed response, then a total peak demand reduction of 375 MW could be achieved, representing more than 25 per cent of Ontario's target for energy conservation. It was concluded that demand response often involves the investment of capital and new on-site procedures, which may affect reactions to various incentives. 78 refs., 10 tabs., 5 figs

    Findings of an independent review of charges to electricity bills and recommendations to assist in the development of a standard, province-wide residential electricity bill for Ontario are discussed. The review was requested by the province's Minister of Energy in an effort to dispel growing confusion about the variations in customer billing practices used by the province's 90+ local distribution companies. Key recommendations and findings were as follows: (1)Consumer bill formats issued by local distribution companies should be more consumer-friendly, adhere to minimum design standards, adapt uniform terminology and common line charges; (2) charges on customer bills should be grouped into four standard line items, with full details available to customers: the four line items should be a basic service charge, a charge for delivering electricity to the customer, a charge for the electricity itself, and a separate charge for retiring the outstanding debt of the former Ontario Hydro; (3) bills should take advantage of opportunities for promoting province-wide energy conservation, such as encouraging the long-term use of interval meters, presenting historical consumption data on residential bills on a period-to-period basis, and education and communications initiatives. Details of the recommendations, including the calculation of the fixed and variable components of usage charges, an explanation of the concept of electricity system loss adjustments, a method for phasing in the recommendations, and the anticipated benefits to consumers are provided

    International Nuclear Information System (INIS)

    1983-05-01

    Due to the economic recession, primary electrical energy demand for the year failed to exceed that of the previous year for the first time since 1944. Actual demand was 100.8 billion kWh, 0.8 per cent below 1981. However, annual peak demand reached 18.1 million kW on January 18, an all-time high, and 5.4 per cent over January 1981. There were 104.1 billion kWh of electricity generated during the year, nearly equally from nuclear, coal, and water power. Nuclear generating units continued their outstanding performance. Bruce-3 completed a 494-day run at continuous power. NPD Generating Station celebrated 20 years of operation. Pickering B unit 5 started up and produced its first power. At Bruce A, a remote-controlled vehicle was used to remove damaged fuel to a shielded flask, completing the job in a short time with low staff radiation exposure. Bruce B construction progressed on schedule; while at Darlington, design and construction continued at a high level, with 1700 workers on site at year-end. Actual net income was $348 million, $38 million below forecast. Coal deliveries were 13.4 million Mg (23 per cent over 1981). Nuclear fuel deliveries to generating stations were 996 Mg (3 per cent over 1981). Agreements were negotiated for the supply of 5200 Mg of uranium concentrates during 1985-93. Nuclear fuel manufacturing contracts were awarded at lower prices than previously attained. Income totalling $163 million from electricity exports to the U.S.A. reduced overall cost of providing electricity to Ontario customers by 5.1 per cent. The Residential Energy Advisory Program surveyed 16,000 homeowners wishing to improve home energy efficiency. There were 20,000 residential customers who received grants to convert from oil to electric heating. Additional consumption resulting from these conversions is estimated at 280 million kWh

    1997-01-01

    Research and development expenditures by Exxon Corporation, one of the major multi-national oil companies, was studied in an effort to demonstrate the manner in which research and development is planned, managed and financed on a global scale, and to discern the role played in the worldwide network of Exxon Corporation laboratories by Exxon's main Canadian affiliate, Imperial Oil Limited of Sarnia. The findings are based upon close examination of all public documents regarding Exxon and its affiliates since 1882 to 1975, and interviews with research personnel. It was described how in the 1920s, the Sarnia research centre of Imperial Oil began to develop its expertise in lubricant research, earning a world research mandate in 1967 with exclusive rights in this area for the entire Exxon Corporation. It is evident that by being able to concentrate in areas that took advantage of their technological competence and expertise while, on the other hand, ensuring that the processes and products generated by the whole network of laboratories were available and adapted to the Canadian context, the commercial impact of Imperial's research and development efforts have been greatly enhanced by its affiliation with the large multinational company. 27 refs

    The freight (cargo) transportation sector accounts for a major use of fossil fuels and contributes significantly to greenhouse gas emissions. A study was conducted to estimate and forecast emissions from transportation in Ontario, by mode, over the next 15 years, and to examine ways in which those emissions could be reduced. Published data of freight transportation industries was used to examine the fuel consumption characteristics of each mode, followed by a review of emission rates. It was determined that truck transportation accounts for most CO 2 emissions (about 70%). Rail follows with 21% and the marine and air modes contribute relatively small shares (6% and 2%). New intermodal technologies being introduced by the railways were discussed. They have been designed to make intermodal transport more accessible to a wider segment of the freight market. A recommendation was made which would require all truck shipments over 500 km, accounting for fully one half of truck tonne-km, to have their line-haul component diverted to this new more fuel-efficient mode (i.e., from truck to rail). refs., tabs., figs

    2009-01-01

    To identify socio-demographic factors associated with household food insecurity in the Ontario population. Using data from the Ontario Share File of the 2004 Canadian Community Health Survey, Cycle 2.2, multivariate logistic regression was applied to identify the socio-demographic characteristics of households most likely to report food insecurity. Of the estimated 379,100 food-insecure households in Ontario in 2004, 55% were reliant on salaries or wages, 23% on social assistance, and 13% on pensions or seniors' benefits. The prevalence of food insecurity increased markedly as income adequacy declined, rising to 47% in the lowest category of income adequacy. Food insecurity was also more prevalent among tenant households and single-person and single-parent households. When all socio-demographic factors were taken into account, three potent socio-demographic correlates of household food insecurity in Ontario were identified: low income adequacy, social assistance as the main source of income, and not owning one's dwelling. Compared to households whose main source of income was salary or wages, the adjusted odds of experiencing food insecurity was 3.69 (95% CI: 2.33, 5.84) for households reliant on social assistance, but 0.44 (95% CI: 0.29, 0.67) for those reliant on pensions or seniors' benefits. Our findings highlight the need for more adequate social assistance benefit levels, but also point to the need for better income supports for low-waged workers in Ontario so that they have sufficient financial resources to purchase the food they need.

  2. Ontario electricity rates and industrial competitiveness

    International Nuclear Information System (INIS)

    2006-01-01

    Industrial electricity prices in Ontario rose significantly after the opening of the competitive Ontario electricity market in 2002, thereby widening the gap between industrial electricity prices in Ontario and those in other Canadian provinces. Navigant Consulting Ltd. conducted this study at the request of the Association of Major Power Consumers in Ontario (AMPCO) to research and compare current and historical electricity prices in Ontario and other jurisdictions in North America. The study provided an independent analysis of how industrial electricity prices in Ontario compare to those in other jurisdiction in which AMPCO members operate. It also formed the basis for comparing the impacts of electricity policy on the economic competitiveness of major power consumers in Ontario. The relative electricity intensity in the United States, Ontario and other Canadian provinces was reviewed for specific industries, including forest products, steel manufacturing, petroleum refining, chemical manufacturing and cement manufacturing. Publicly available aggregate data from Statistics Canada and the United States Bureau of the Census was then used to compare average electricity prices for industrial customers in Ontario. The data confirmed that Ontario has experienced a decline in its competitive price advantage in industrial electricity. Delivered industrial electricity prices in Ontario have increased by more than 60 per cent since 2001. Industrial electricity prices in Ontario rose above those in Quebec, Manitoba, British Columbia and New Brunswick. In addition, industrial electricity prices in Ontario rose above those in competing states such as Ohio and Illinois, in part due to the increase in the value of the Canadian dollar. It was concluded that the price increase may lead to a greater decline in economic output in Ontario compared to competing jurisdictions. 2 tabs., 14 figs., 1 appendix

  3. 18-month outlook : An assessment of the adequacy of the Ontario electricity system from January 2002 to June 2003

    2001-01-01

    The Independent Electricity Market Operator (IMO) has monitored the state of electricity demand and available supply in Ontario and has reported its findings to the Minister of Energy, Science and Technology and to the Ontario Energy Board. This report presents the IMO's assessment of the adequacy of resources and transmission for the Ontario electricity system for the 18-month period from January 2002 to June 2003. The assessment was based on current information on forecasts of electricity demand and available supply. The existing installed generation within Ontario was summarized. Existing power facilities include nuclear, coal, oil, gas, hydroelectric, wind-powered, wood and waste-fuelled generation. The installations range from less than 1 MW in size to 881 MW net electrical output. The total generating capacity in Ontario is 29,523 MW, excluding embedded generators that are not managed by the Ontario Electricity Financial Corporation or generation not connected to the IMO-controlled grid. In addition, the Bruce Nuclear Unit was not included because it is currently in laid-up state. This report discussed changes from the previous 18-month outlook in terms of power demand. It also presented outlooks of the transmission outage plan, system voltage, thermal concerns and forced outages. The general conclusion reached in this report is that there will be sufficient resources and transmission available to Ontario to supply Ontario demands and to meet the Northeast Power Coordinating Council (NPCC) resource criteria for the next 18 months. tabs., figs

    Ontario is Canada's most populous province, with approximately 12 million people and 130 emergency departments (EDs). Canada has a national single-payer universal health care system, but provinces are responsible for administration. After years of problems and failed attempts to address chronic ED overcrowding, in April 2008 Ontario embarked on an ambitious program to improve system performance through targeted investments (initially CAN$500 million over 3 years) and realigned incentives. Supporting the program were requirements for hospitals to submit timely data and targets for length of stay (LOS) and annual improvements; results are publicly reported. The program has been continued this year. While not all our provincial level targets have been met as yet, major improvements have been made, especially in access to care and LOS in the ED for patients eventually discharged home. The greatest improvements were made among the cohort of mainly urban, high-volume EDs that had the worst performance at baseline. This presentation will highlight some of the controversies and challenges and key lessons learned. Overall, the Ontario experience suggests ED overcrowding is a soluble problem, but requires a system-level intervention. © 2011 by the Society for Academic Emergency Medicine.

    1990-04-05

    A chemical plant in Sarnia, Ontario applied before the Ontario Energy Board for permits to drill wells to extract brine by solution mining from underground salt deposits located within 1 mile of existing underground natural gas storage facilities. A hearing was held to consider matters related to the application. The primary concern at the hearing was protection of the gas storage facility from damage arising from the proposed operations. The applicant stated that no hydrofracturing would be performed and that brine operations would be carried out at low pressure. Geologic evidence was presented to show the physical separation of the proposed brine caverns from the gas storage areas. It was noted that the proposed caverns would be vertically separated from the gas storage area by relatively impervious anhydrite. Other environmental concerns included possible contamination of aquifers and surface waters by leakage from the wells or from storage ponds. The Board found that the proposed injection wells and brine recovery operations pose no foreseeable risk to the gas storage areas and that the applicant's precautions to avoid environmental contamination appear satisfactory. The drilling permits were approved subject to certain conditions. 2 figs.

    This case study shows that the diffusion of nuclear power in the electric public utility industry in Canada approximates the logistic growth curve, in agreement with previous results on technological innovation diffusion in the U.S. private sector. Many of the economic variables that affect this diffusion in the private sectors in the U.S. and Canada are also significant in the public sector in Canada. Too few utilities have adopted nuclear technology to permit using regression analysis to study the effect of environmental and regulatory factors on the growth of Ontario Hydro. Thus, cost-benefit analysis for each province might be more effective

    The history of acupuncture in Ontario, Canada was traced, and the current status as welI as the prospection were introduced in this paper. Statistics showed that the history of acupuncture in Ontario started in the 1880s, and it was only popular in China Town and Chinese community. In the 1970s, it gradually merged into the mainstream of the society, and entered into a growing period. With the tide of Chinese immigration in the 1980s and 1990s, acupuncture matured rapidly. In 2006, the "Traditional Chinese Medicine Act" was passed in Ontario, it was considered as a milestone in the history of acupuncture. At present, just like the other 23 health care professions, acupuncture has already be included into the legislation system, and become a component of Ontario's health care system. At the same time, the law and regulation may also promote the establishment of "pure Chinese Medicine" in Ontario.

  16. The uranium deposits of Ontario

    1981-01-01

    The principal types of uranium deposits in Ontario are carbonatites and fenites, alkalic volcanic rocks, pegiatites, calc-silicate rocks, pyritic quartz-pebble conglomerates, polymictic conglomerates and some pelitic rocks, and various 'pitchblende' deposits including late Precambrian unconformities, possibly late Precambrian diabase dikes, and other unconformities: carbonates, sandstones, lignites, and semi-pelitic rocks of middle and upper Precambrian age. Only red unzoned pegmatite and the pyritic quartz-pebble conglomerate have supported production. Ontario reasonably assured and estimated resources in the economic and subeconomic categories in 1977 amounted to 553 000 tonnes U, and 1977 production was 4000 tonnes U. Measured, indicated, and inferred resources in the Elliot Lake - Agnew Lake area are at least 400 000 tonnes U. The latter deposits are also a significant thorium resource. Geological features reflecting major changes in physics and chemistry are prime controls on distribution of uranium deposits. Geological province and subprovince boundaries, major faults, higher metamorphic grades, domain boundaries related to quartz monzonite batholiths, alkalic complexes, and the distribution of carbonate rocks are examples of such geological features

    Green energy is defined as the energy generated from renewable and environmentally benign sources. In this document, the authors demonstrated that Ontario possesses the potential to reduce energy waste on an economic basis while generating sufficient green energy to enable the province to decommission its coal burning power plants. In turn, this would lead to a more sustainable energy economy and a lesser reliance on nuclear generation. It was determined that a three-fold policy would enable the province to achieve this goal. First, there is a need to remove hidden subsidies to polluting forms of generation. The second aspect of this policy is the implementation of a robust Demand Side Management Program, and the third aspect calls for the reform of the price of electricity that includes all costs. In this manner, all forms of generation would compete on an equal footing. The authors identified an alternative to immediate price reform in the form of a legislated Renewable Portfolio Standard. A growing percentage of new renewable electricity in the supply portfolio offered by electricity providers would be required by the Renewable Portfolio Standard. It was suggested that the Ontario government adopt this measure before the opening of the electricity market in May 2002, as strong support for the measure is present. 13 refs

    A pilot project for renewable energy technologies (RET) by Ontario Hydro was discussed. The program focusses on the solar, wind, micro hydro, biomass, waste recovery, fuel cell, hydrogen and hybrid technologies industries. The program is planned in two stages, with the intention of making RETs commercially viable sources of energy in Ontario, while giving Ontario Hydro the technology and experience to be competitive in renewable energy industries. Northern communities provide good opportunity for developing renewables because, although RETs are generally more costly than grid connected power sources, they are more competitive when compared with costs associated with remote diesel generated power. 1 fig.

  19. Meeting Ontario's electricity needs : a critical review of the Ontario Power Authority's supply mix advice report

    2006-01-01

    In December, 2005 the Ontario Power Authority (OPA) outlined its proposed blueprint for meeting Ontario's electricity needs to 2025 in the document entitled Supply Mix Advice Report. As a result of the actions taken by the current government, the OPA believes that Ontario will have adequate electricity supplies to meet the province's needs until 2013. However, it stated that Ontario will require an additional 15,000 megawatts of new generation capacity between 2013 and 2025. The OPA also recommends that a significant proportion of this new generation capacity be nuclear. The Ontario Clean Air Alliance undertook a review of the OPA report and identified several discrepancies including an over-estimation of Ontario's rate of electricity load growth from 2005 to 2025; an under-estimation of the potential for electricity productivity improvements to reduce electricity demand and raise living standards; an under-estimation of renewable energy supply potential; an under-estimation of the potential for biomass and natural gas fired combined heat and power plants to meet electricity needs and increase the competitiveness of Ontario's industries; an under-estimation of the economic costs and risks of nuclear power; and a biased recommendation for a 70 million dollar resource acquisition budget against energy efficiency investments that would reduce demand and raise living standards. This report provides the Ontario Clean Air Alliances' analysis of the OPA report and presents it own recommendations for how Ontario can increase its electricity productivity and meet its electricity supply needs until 2025. The report concluded that the Government of Ontario should direct the OPA to develop a long-term strategy to raise the price of electricity up to its full cost without raising the electricity bills of low income consumers or impairing the competitiveness of Ontario's industries. It was suggested that Ontario's electricity productivity should be increased to the same level as

    Seven per cent of the greenhouse gas emissions from the industrial sector in Ontario relate to the food and beverage processing sector. This report provides the Ontario Ministry of Agriculture, Food and Rural Affairs with the ability to identify the effects of reducing greenhouse gas emissions on Ontario's food and beverage processing sector. The study was undertaken in response to Ontario's efforts to address the challenges set by the Kyoto Protocol and the proposed release of Canada's National Implementation Strategy on Climate Change. The objective of the report is to help Ontario decide if it should support a national strategy and/or ratify the Kyoto Protocol. Potential ways to meet the Kyoto commitments were also identified in the report. The study was based on an analysis of large amounts of data and information regarding the economic and technological aspects that affect the food and beverage processing industry in Ontario, including the seven major sub-sectors, located mostly in southern Ontario. The types of plants and their associated processes and fuel use were assessed to determine the size and nature of fuel use and greenhouse gas emissions for each sub-sector. The study examined end uses and base technologies for each sub-sector and compared them with energy efficient technologies and opportunities within the industry. Barriers, and how to overcome them, were also described. Ontario's results were then compared with results from Canada's Foundation Paper and Options Analysis prepared for the Agriculture and Agri-Food Table on Climate Change. It was determined that the primary source of greenhouse gases for the industry comes from the use of energy directly from the combustion of fossil fuels and indirectly from the use of electricity. The contributions to greenhouse gases through chlorofluorocarbons or through waste stream is small and shrinking. It was concluded that mitigation strategies should concentrate on energy

    Jensen, M.

    2009-05-01

    Ontario Power Generation is proposing to develop a Deep Geologic Repository (DGR) for the long-term management of its Low and Intermediate Level Radioactive Waste (L&ILW) at the Bruce site located near Tiverton, Ontario, 225 km northwest of Toronto. The shaft accessed repository, as envisioned, would accommodate 200,000 m3 (as packaged) of L&ILW in emplacement rooms excavated at a depth of 680 m within the Ordovician age argillaceous limestone Cobourg Formation. The Bruce site is underlain by an approximate 860 m thick Paleozoic sedimentary sequence comprised of near horizontally bedded carbonates, shales, evaporates and sandstones, Devonian to Cambrian in age, overlying crystalline basement rocks. Regional and site-specific geoscientific studies to verify the suitability of the Bruce site to host the DGR were initiated in 2006. The focus for the geoscientific investigations has been on gathering data to develop and test an understanding of the evolution and stability of the geologic, hydrogeologic, hydrogeochemical and geomechanical environ as it relates to demonstrating repository safety. Scheduled for completion in 2010, the interim results, which have included the drilling, coring and testing of 4 deep boreholes, are providing evidence of a predictable geosphere with a deep seated (>400 m), low permeability (K 250 gm l-1) groundwater regime that is ancient and resilient to external perturbations (e.g. glaciation). Work program activities in this regard have included, among others, detailed studies of rock core lithology, mineralogy and petrophysics, rock matrix pore fluid and groundwater characterisation, in-situ rock mass hydraulic testing, geomechanical rock core testing, 2-D seismic reflection surveys and long-term hydraulic borehole instrumentation. These data, in addition to regional and site-scale hydrogeologic modelling of the sedimentary sequence that among other aspects is examining groundwater system evolution through an understanding of long

    Brett, J.T.

    1997-01-01

    The current status of the natural gas industry and the electric power industry in Ontario, in terms of deregulation, was described. Natural gas utilities will exit the regulated gas market over the next few years and transfer their existing residential and small commercial gas contracts to their unregulated affiliates. Nevertheless, a regulated gas supply option will remain until the regulator is assured that consumer protection issues have been properly addressed, and there is a truly competitive market. Ontario Hydro is a vertically integrated virtual monopoly. It lags behind B.C., Alberta, Quebec and Nova Scotia in terms of deregulation and restructuring, although the MacDonald Commission's recent report recommended sweeping changes to Ontario Hydro's monopoly over the electric power industry. A final response from the Ontario government is still pending. The convergence of the electric power and natural gas industries was also discussed

    Ontario Hydro, North America's largest electric power utility, with an installed capacity of 34,000 MW, has under gone a major restructuring over the past year to better align itself with a changing electricity market and evolving customer needs. The single largest new business unit within the new Ontario Hydro is Ontario Hydro Nuclear (OHN), responsible for engineering, operation and maintenance of the Corporation's 20 large nuclear units at three generating sites, OHN faces a significant challenge in returning Ontario's nuclear units to the world-leading performance levels they enjoyed in the past, particularly the older Pickering A and Bruce A plants. However, steady progress is being made as evidenced by improving peer reviews and overall capacity and financial performance

    Rowlands, I.H.

    2006-01-01

    The Ontario electricity supply is facing considerable challenges while demand is increasing due to a growing population and increased economic growth needs. In response to these challenges, the government of Ontario established the Ontario Power Authority (OPA) in 2004 to ensure adequate, reliable and secure electricity supply and resources in Ontario. The OPA has also engaged in activities to facilitate the diversification of sources of electricity supply by promoting the use of cleaner energy sources and technologies, including alternative energy sources and renewable energy. The purpose of this paper was to advance discussions regarding the contribution that solar PV can make to Ontario's supply mix. In particular, it determined the value of the electricity that would have been produced by a PV system located in Waterloo, Ontario under the following 4 pricing regimes: (1) the conventional small user tariff system currently in place in Ontario, (2) the time-of-use pricing system that is voluntarily available to those who have smart meters installed in their facilities, (3) the spot market, hourly prices, to which some of Ontario's largest electricity users are exposed, and (4) the recently-proposed rate for standard offer contracts for PV systems. The study showed that a solar PV system that produces 3,000 kWh of electricity over the course of a year would generate different revenue amounts, ranging from the smallest amount of approximately $174.00 to $1,260.00, depending on the pricing regime. The pricing regime that reflects real, time-of-day electricity prices appears to be most advantageous to solar PV systems. It was recommended that additional work is needed regarding the other benefits of solar PV, such as avoided capacity/generation needs, avoided transmission and distribution cost and losses, environmental benefits, and job creation. 3 refs., 4 tabs., 8 figs

    Ontario continues a strong growth in electricity consumption; over the past five years consumption has risen an average of 5 percent a year. In 1988 consumption rose by 6.5 percent to 133.1 billion kilowatt-hours. Peak demand was 23 million kilowatts. The top priority for the 1990s will be improving the energy efficiency of customers and the operating efficiency of the Corporation, with a target saving of 4500 megawatts through demand management and energy efficiency by the year 2000. A new environmental division has been formed, as well as a division for non-utility generation. Safety is of particular importance to the Nuclear Generating Division; in all nuclear operations, after 143 million hours worked from 1955 to 1988, there has never been a work-related fatality or a detectable injury due to radiation. The average radiation dose per worker continues to decline and is now under 10 percent of the legal dose limit. Retubing of Pickering Nuclear Generating Station unit 2 has been completed. Retubing of unit 1 is under way, and work on units 3 and 4 has been approved. Construction continues on the Darlington Nuclear Generating Station, where the first unit is expected to go into service in 1989. The Darlington Tritium Removal Facility was completed

  10. Introducing Physician Assistants to Ontario

    2014-02-01

    Full Text Available In 2006, the Ontario Ministry of Health and Long-Term Care (MOHLTC introduced Physician Assistants (PAs through the announcement of demonstration projects, education and training programs, and subsequent funding. PAs are directly supervised by physicians and act as physician extenders by performing acts as delegated to them by their supervising physicians. PAs were proposed as a potential solution to help improve access to health care and reduce wait times throughout the province. Prior to the 2006 Ministry announcement, there was little public discussion regarding the acceptance of the PA role or its sustainability. Opposition from nursing and other groups emerged in response to the 2006 announcement and flared again when stakeholder comments were solicited in 2012 as part of the PA application for status as regulated health professionals. As a health reform, the introduction of PAs has neither succeeded nor failed. In 2013, the majority of PA funding continues to be provided by the MOHLTC, and it is unknown whether the PA role will be sustainable when the MOHTLC withdraws salary funding and health system employers must decide whether or not to continue employing PAs at their own expense.

  11. Implications of the Ontario government's white paper and competition strategies for Ontario's municipal electric utilities

    International Nuclear Information System (INIS)

    Wills, D.L.

    1998-01-01

    The strategies that Municipal Electric Utilities (MEU) should follow to deal with competition were discussed. North Bay Hydro is the 34th largest MEU out of 300 in Ontario but it serves only 23,000 out of 4 million electrical customers in Ontario. Therefore, the main strategy for municipal utilities to ensure their future would be to become part of an alliance and association like the MEA and the SAC - the Strategic Alliance for Competition and Customer Choice. Strong criticism was voiced regarding the contents of the recent Ontario Government White Paper for being vague with regard to electrical distribution and the role of MEUs in Ontario. It was suggested that it is vitally important that MEUs ally themselves with other stakeholders, to resist an Ontario Hydro monopoly, to make sure that prices stay low, to avoid excessive debt and bureaucratic inefficiency, be innovative, and consumer oriented and be prepared to anticipate events and conditions. 3 figs

    The recent measures taken by Ontario Power Generation since 1998 to deregulate the electricity market in the province of Ontario are reviewed. The opening of Ontario's power market in May 2002 will oblige Ontario Power Generation to reduce its market share. The author reviewed the current status of the energy market in Ontario and noted a modest growth in demand. A significant portion of the energy supply is being provided by nuclear, fossil fuels and hydro energy. The challenge facing Ontario Power Generation is to stay competitive in the new deregulated market and to participate in the energy market in the United States. 6 figs

    In 2008, the U.S. Geological Survey (USGS), Woods Hole Coastal and Marine Science Center (WHCMSC), in cooperation with the U.S. Army Corps of Engineers conducted a geophysical and sampling survey of the riverbed of the Upper St. Clair River between Port Huron, Mich., and Sarnia, Ontario, Canada. The objectives were to define the Quaternary geologic framework of the riverbed of the St. Clair River to evaluate the relationship between morphologic change of the riverbed and underlying stratigraphy. This report presents the geophysical and sample data collected from the St. Clair River, May 29-June 6, 2008, as part of the International Upper Great Lakes Study, a 5-year project funded by the International Joint Commission of the United States and Canada to examine whether physical changes in the St. Clair River are affecting water levels within upper Great Lakes, to assess regulation plans for outflows from Lake Superior, and to examine the potential effect of climate change on the Great Lakes water levels (http://www.iugls.org). This document makes available the data that were used in a separate report, U.S. Geological Survey Open-File Report 2009-1137, which detailed the interpretations of the Quaternary geologic framework of the region. This report includes a description of the high-resolution acoustic and sediment-sampling systems that were used to map the morphology, surficial sediment distribution, and underlying geology of the Upper St. Clair River during USGS field activity 2008-016-FA (http://quashnet.er.usgs.gov/cgi-bin/datasource/public_ds_info.pl?fa=2008-016-FA). Video and photographs of the riverbed were also collected and are included in this data release. Future analyses will be focused on substrate erosion and its effects on river-channel morphology and geometry. Ultimately, the International Upper Great Lakes Study will attempt to determine where physical changes in the St. Clair River affect water flow and, subsequently, water levels in the Upper Great

    Jantzi, B.

    2001-01-01

    In this presentation, the author discussed Ontario Power Generation's voluntary commitment to stabilize carbon dioxide equivalent emissions at 1990 levels. To do so, Ontario Power Generation is implementing a series of green energy initiatives, a corporate tree planting program, internal energy efficiency, and an emission reduction trading (ERT). The emphasis was placed on emission trading, where Ontario Power Generation is a leader in the field of greenhouse gas, nitrogen oxide and sulphur dioxide trading in Canada. The approach to trading adopted was explained, with the specifics provided for each of the different categories of emissions. Some examples further illustrated the process. The outlook for the future was outlined, with plans for the geological sequestration of carbon dioxide and enhanced oil recovery, low nitrogen oxide gasoline additive. The benefits of emission trading were discussed from the perspective of Ontario Power Generation and the environment, such as allowing real reductions in emissions in a cost effective manner, enhanced risk management, investments in emissions reductions. The author argued that emission reduction is the way of the future, representing the only way in which the greenhouse gas emissions reductions required to minimize global climate change will be accomplished

  15. Marketing program for R2000 in Ontario

    Killins, B.L.

    1990-01-01

    In the Ontario new housing market, Ontario Hydro's goal is to reduce the demand for electricity, increase the utility's visibility in this market, and increase customer satisfaction. Analyses have demonstrated that it costs less to construct new houses according to R-2000 insulation standards than to install new power production and transmission facilities. Research has also shown that R-2000 houses have better air quality and energy efficiency than ordinary houses. Nevertheless, most home builders have little enthusiasm for R-2000 houses; the strictness of airtightness standards, the slowness of certification, excessive paperwork, and a lack of promised marketing support are cited as the reasons for this. Ontario Hydro and builders' associations have signed a cooperative agreement for certifying new houses with the object of self-financing the program. The program intends to see construction of 1,000 R-2000 houses in 1990. To carry out this objective, some elements have been added to Ontario Hydro's marketing program in order to make potential customers aware of the advantages of the R-2000 house. Field staff will receive rigorous training in order to prepare them for helping the diverse types of builders. A mail campaign, focusing on areas not served by natural gas where significant numbers of new houses are being built, intends to bring home builders and buyers together. In February 1990, Ontario Hydro signed agreements with four major housing manufacturers to construct a significant proportion of the R-2000 housing stock

    2004-01-01

    This paper presents a comparison between nuclear generation and other existing power generation, with particular reference to the natural gas industry. The aim of the paper was to present a rationale for an extensive nuclear restart in the near future in Ontario. An energy forecast was provided, generating capacity requirements were examined, with particular reference to requirements beyond conservation and renewable energy supplies. The cost effectiveness of nuclear rehabilitation was compared to combined cycle gas turbines (CCGT) in terms of capital and non-fuel costs. Future prospects of gas prices were discussed, as well as the possibilities of demand outstripping supply. CCGT costs were compared to nuclear rehabilitation in terms of overall electricity prices, including capital, non-fuel operating costs and fuel costs. Steps towards making the nuclear option a reality included a sustainable market environment; clear policy framework; a balanced energy mix; long term price certainty; and clear regulatory requirements. In was concluded that in order to regenerate its potential, the nuclear industry must demonstrate world class project management; fixed scope; fixed supplier prices; program commitment; guarantees; and realistic future production estimates. It was also concluded that nuclear restart and life extension was an extremely attractive option for consumers, offering long term stable competitive power, with fuel diversity and future reserves as well as zero greenhouse gas emissions and an optimization and use of existing facilities. Challenges in creating the right climate for nuclear rehabilitation were the difficulties in making the nuclear option attractive to investors as well as developing correct estimation of project times, costs, and scopes and allocation of project risks. tabs., figs

    Issues concerning the social acceptance of wind energy are major challenges for policy-makers, communities and wind developers. They also impact the legitimacy of societal decisions to pursue wind energy. Here we set out to identify and assess the factors that lead to wind energy disputes in Ontario, Canada, a region of the world that has experienced a rapid increase in the development of wind energy. Based on our expertise as a group comprising social scientists, a community representative and a wind industry advocate engaged in the Ontario wind energy situation, we explore and suggest recommendations based on four key factors: socially mediated health concerns, the distribution of financial benefits, lack of meaningful engagement and failure to treat landscape concerns seriously. Ontario's recent change from a feed-in-tariff-based renewable electricity procurement process to a competitive bid process, albeit with more attention to community engagement, will only partially address these concerns.

    This case study outlines key considerations for healthcare organizations experiencing significant transformational change, based on the experience of Ontario Shores Centre for Mental Health Sciences (Ontario Shores), formerly Whitby Mental Health Centre. Significant systemic change requires specific and intentional efforts from the leaders tasked with carrying out transformational activities. This article presents the perspectives of leaders involved in the transformation of Ontario Shores as it moved from a government-based agency to a stand-alone specialty psychiatric hospital in 2006. During this time, several conventional strategies were employed to manage the transition, but various critical approaches also emerged that assisted the organization to effect significant change and achieve marked improvements over key evaluation metrics. These critical strategies included maximizing the distinct and collective roles of governance and leadership; balancing strategy and action through a culture of accountability; leveraging strategic communication opportunities; and shifting the organizational mindset.

    This, the second edition of the uranium-thorium deposit inventory, describes briefly the deposits of uranium and/or thorium in northern Ontario, which for the purposes of this circular is defined as that part of Ontario lying north and west of the Grenville Front. The most significant of the deposits described are fossil placers lying at or near the base of the Middle Precambrian Huronian Supergroup. These include the producing and past-producing mines of the Elliot Lake - Agnew Lake area. Also included are the pitchblende veins spatially associated with Late Precambrian (Keweenawan) diabase dikes of the Theano Point - Montreal River area. Miscellaneous Early Precambrian pegmatite, pitchblende-coffinite-sulphide occurrences near the Middle-Early Precambrian unconformity fringing the Lake Superior basin, and disseminations in diabase, granitic rocks, alkalic complexes and breccias scattered throughout northern Ontario make up the rest of the occurrences

    Full Text Available In response to the growing role of personal support workers (PSWs in the delivery of health care services to Ontarians, the Ontario government has moved forward with the creation of a PSW registry. This registry will be mandatory for all PSWs employed by publicly funded health care employers, and has the stated objectives of better highlighting the work that PSWs do in Ontario, providing a platform for PSWs and employers to more easily access the labour market, and to provide government with information for human resources planning. In this paper we consider the factors that brought the creation of a PSW registry onto the Ontario government’s policy agenda, discuss how the registry is being implemented, and provide an analysis of the strengths and weaknesses of this policy change.

    Since the mid-1970s, successful Lake Ontario management actions including nutrient load and pollution reductions, habitat restoration, and fish stocking have improved Lake Ontario. However, several new obstacles to maintenance and restoration have emerged. This special issue presents management-relevant research from multiple agency surveys in 2011 and 2012 and the 2013 Cooperative Science and Monitoring Initiative (CSMI), that span diverse lake habitats, species, and trophic levels. This research focused on themes of nutrient loading and fate; vertical dynamics of primary and secondary production; fish abundance and behavior; and food web structure. Together these papers identify the status of many of the key drivers of the Lake Ontario ecosystem and contribute to addressing lake-scale questions and management information needs in Lake Ontario and the other Great Lakes and connecting water bodies.

  6. Global warming: Towards a strategy for Ontario

    International Nuclear Information System (INIS)

    1990-01-01

    A discussion paper is provided as background to a proposed public review of a strategy for Ontario's response to global warming. Global warming arises from the generation of greenhouse gases, which come from the use of fossil fuels, the use of chlorofluorocarbons, and deforestation. Energy policy is the backbone of achieving climate stability since the burning of fossil fuels releases most of the greenhouse gases, mainly carbon dioxide. Canada is, by international standards, a very energy-intensive country and is among the world's largest emitters of carbon dioxide on a per capita basis. Ontario is the largest energy-using province in Canada, and fossil fuels represent over 80% of provincial energy use. A proposed goal for Ontario is to provide leadership in stabilizing atmospheric concentrations of the greenhouse gases, while minimizing the social, economic, and environmental costs in Ontario of adapting to global warming. A proposed first step to address global warming is to achieve reductions in expected emissions of the greenhouse gases, especially carbon dioxide, so that levels by the year 2000 are lower than in 1989. Current policies and regulations helping to reduce the greenhouse effect include some of the current controls on automotive emissions and the adoption by the provincial electric utility of targets to reduce electricity demand. New initiatives include establishment of minimum energy efficiency standards and reduction of peak-day electricity use. Action steps for future consideration are detailed in the categories of greenhouse gas emissions reductions, carbon dioxide absorption, and research and analysis into global warming

    None of the 8 species of bats in Ontario are considered as species at risk. However, all bats in Ontario are protected under the Fish and Wildlife Conservation Act. The Ontario Ministry of Natural Resources (MNR) is responsible for identifying significant wildlife habitat for bats, including hibernacula and maternity roosts. The MNR's role in wind development includes environmental assessments (EA) and surveys. The MNR bat guideline includes a summary of Ontario species, a literature review of research related to wind turbines and bats, and a review of methods for assessing and monitoring bats. Guideline development includes a bat working group responsible for obtaining data on risk factors and monitoring requirements. The MNR has determined that site selection is critical for minimizing potential impacts. Wind farm proponents can use MNR data, information, and maps for their site selection process. Information requirements include bat species data; habitat data; and meteorological data. The presence of risk factors results in a sensitivity rating. The MNR is also developing a site sensitivity mapping project in order to assist proponents in making siting decisions. All proposed sites are required to conduct pre-construction site surveys. Acoustic detectors and radar are used to determine bat activity at the site. Monitoring and mitigation strategies include selective wind turbine shutdown during key periods or weather conditions. tabs., figs.

  12. Seven steps to an energy efficient Ontario

    International Nuclear Information System (INIS)

    2003-01-01

    The future of the electricity market in Ontario is examined in light of the recent debate concerning deregulation. This report focuses on measures that would have to be taken to ensure that there will be sufficient electricity available to serve the needs of Ontario. Increasing supply, or decreasing demand are discussed as the obvious answers to the problem at hand. The report concludes that: (1) mechanisms to encourage Demand Side Management and Demand Response have all but disappeared since the opening of the competitive electricity market in Ontario, (2) the current market structure does nothing to stimulate increased supply, nor does it encourage measures to reduce demand; as such, the result is an unsustainable situation. The report further concludes that Demand Side Management and Demand Response programs are essential components of the success of Ontario's evolving electricity market, and recommends programs that are designed and implemented in a manner that dovetail with parallel policies dealing with supply challenges. Seven essential elements of such a policy are discussed. These are: (1) vision and a clear set of goals for demand side management; (2) appropriate market drivers, principles and pricing incentives; (3) a central co-ordinating authority for managing demand side management; (4) appropriate implementation agents to manage programs and processes; (5) incentives to motivate change; (6) widespread education of the market; and (7) appropriate tactics to enable demand side management in sectors

    2007-11-01

    The Ontario Sustainable Energy Association (OSEA) promotes the development of community-owned renewable energy generation. It was emphasized that in order to achieve OSEA's original objectives of developing as much renewable energy as quickly as possible through community participation, changes are needed to Ontario's groundbreaking standard offer contract (SOC) program. This report examined the status of Ontario's SOC program and proposed changes to the program as part of the program's first two-year review. The report provided a summary of the program and discussed each of the program's goals, notably to encourage broad participation; eliminate barriers to distributed renewable generation; provide a stable market for renewable generation; stimulate new investment in renewable generation; provide a rigorous pricing model for setting the tariffs; create a program applicable to all renewable technologies; provide a simple, streamlined, and cost-effective application process; and provide a dispute resolution process. The program goals as developed by the Ontario Power Authority and Ontario Energy Board were discussed with reference to mixed results to date; simplicity; removing barriers; balancing targets with value to ratepayers; and building on the efforts of OSEA. Advanced renewable tariffs (ART) and tariff determination was also discussed along with ART's in Germany, France, Spain and Ontario. Inflation indexing; tariff degression; proposed new tariffs by technology; and other costs and factors affecting profitability were also reviewed. ref., tabs

Smog also contributes to environmental problems such as damage to forests, agricultural crops and natural vegetation. The two main ingredients of smog are ground level ozone and particulate matter. In order to reduce the incidence of smog, the following four key smog-causing pollutants must be reduced: nitrogen oxides, volatile organic compounds, sulphur dioxide and particular matter. This paper includes the 2001 estimates for Ontario's emissions inventory along with Ontario's smog reduction targets. It was noted that approximately half of all smog in Ontario comes from sources in the midwestern United States. The province of Ontario is committed to replacing coal-fired power plants with cleaner sources of energy. It is also considering emission caps for key industrial sectors. The key players in reducing smog include municipalities, industry, individuals, the federal government and programs that reduce emissions in the United States. 3 figs., 8 tabs., 1 appendix

  15. Air quality in Ontario: a concise report on the state of air quality in the province of Ontario 1998

    2001-01-01

    Major achievements in reducing total sulphur compounds, carbon monoxide, sulphur dioxide and nitrogen dioxide are reported, notwithstanding sharp increases in the province's population, economic activity and vehicular traffic since the first report in 1971. Despite the reported improvements and the impressive results of the 'Drive Clean' program, air pollution still impacts the health and well-being of Ontarians, with smog, resulting from an increase in ground-level ozone and inhalable particles emissions, being of particular concern. The 'Drive Clean' program is the province's principal weapon in the fight to reduce smog-causing emissions from the No. 1 domestic source, namely cars, trucks and buses. Some 2.5 million light-duty vehicles had been tested as of March 2001, with almost 86 per cent of them passing on the first try. Repairs mandated by the program during its first year led to a reduction of 6.7 per cent in smog-related emissions from light-duty vehicles, as well as an 18,500-tonne reduction in emission of carbon dioxide. When fully implemented by 2004, the 'Drive Clean' program is expected to cover some five million light-duty vehicles in southern Ontario and 200,000 heavy-duty trucks across the province. Mandatory tracking and reporting of all harmful air emissions by industrial and commercial enterprises and tough new emission limits for smog and acid rain-causing pollutants have been announced in April 2000. Power generating plants are also now obliged to monitor and report some 28 substances of concern which include sulphur dioxide, nitrogen oxides and carbon dioxide. In addition to mandatory reporting, the province also introduced new regulated emission limits for nitrogen oxides and sulphur dioxide from coal and oil-fired power stations. More than four million dollars have been invested by the province since 1995 to develop a state-of-the-art air monitoring system. Air quality information is now being provided by 28 communities across Ontario

  16. An Outbreak of Foodborne Botulism in Ontario

    Full Text Available Botulism is a rare paralytic illness resulting from a potent neurotoxin produced by Clostridium botulinum. Botulism in Canada is predominately due to C botulinum type E and affects mainly the First Nations and Inuit populations. The most recent outbreak of botulism in Ontario was in Ottawa in 1991 and was caused by C botulinum type A. We report an outbreak of foodborne type B botulism in Ontario, which implicated home-canned tomatoes. The outbreak was characterized by mild symptoms in two cases and moderately severe illness in one case. The investigation shows the importance of considering the diagnosis of botulism in patients presenting with cranial nerve and autonomic dysfunction, especially when combined with gastrointestinal complaints; it also highlights the importance of proper home canning technique.

    2001-03-01

    This document informs electric power market participants of the Ontario Energy Board's newly developed market readiness plan and target timelines that local distribution companies (LDCs) must meet for retail marketing. The Ontario Energy Board's plan incorporates relevant independent market operator (IMO)-administered market milestones with retail market readiness targeted for September 2001. The market readiness framework involves a self-certification process for LDCs by August 10, 2001, through which the Board will be able to monitor progress and assess the feasibility of meeting the target timelines. For retail market readiness, all LDCs will have to calculate settlement costs, produce unbundled bills, provide standard supply service, change suppliers and accommodate retail transactions. LDCs must be either authorized participants in the IMO-administered market or become retail customers of their host LDC. Unbundled bills will include itemized charges for energy price, transmission, distribution and debt retirement charge. 1 tab., 1 fig

    Watershed mercury (Hg) flux was calculated for ten inflowing rivers and the outlet for Lake Ontario using empirical measurements from two independent field-sampling programs. Total Hg (THg) flux for nine study watersheds that directly drain into the lake ranged from 0.2 kg/yr to 13 kg/yr, with the dominant fluvial THg load from the Niagara River at 154 kg/yr. THg loss at the outlet (St. Lawrence River) was 68 kg/yr and has declined approximately 40% over the past decade. Fluvial Hg inputs largely (62%) occur in the dissolved fraction and are similar to estimates of atmospheric Hg inputs. Fluvial mass balances suggest strong in-lake retention of particulate Hg inputs (99%), compared to dissolved total Hg (45%) and methyl Hg (22%) fractions. Wetland land cover is a good predictor of methyl Hg yield for Lake Ontario watersheds. Sediment deposition studies, coupled atmospheric and fluvial Hg fluxes, and a comparison of this work with previous measurements indicate that Lake Ontario is a net sink of Hg inputs and not at steady state likely because of recent decreases in point source inputs and atmospheric Hg deposition.

  1. Gas marketing strategies for Ontario producers

    Walsh, P.R.

    2000-01-01

    Activity in natural gas exploration and production in the province of Ontario has recently increased due to higher natural gas prices. This paper discussed the issue of how the gas from the new reserves should be marketed. A review of historical pricing and consumption patterns was also presented to better identify how prices of natural gas are determined in Ontario and to forecast the future demand for natural gas. The first trend of interest is the increased use of natural gas in generating electricity to meet cooling needs in the summer months. The second trend is the increase in gas consumption by the industrial sector resulting from increases in process load. Several marketing options are available to Ontario natural gas producers. They can market their gas to third parties at various trading points in the province or they can market it directly to Union Gas Limited, the local gas utility. This paper briefly described how a gas supply contract works with the union, how gas marketing agreement is conducted with a gas marketer, and how a gas marketing arrangement works with a consultant. Some of the pitfalls of marketing natural gas were also described and some recommended some strategies for selling natural gas in the future were presented. 7 figs

    Helbronner, V.

    2010-01-01

    This PowerPoint presentation discussed wind and renewable energy interconnection issues in Ontario. The province's Green Energy Act established a feed-in tariff (FIT) program and provided priority connection access to the electricity system for renewable energy generation facilities that meet regulatory requirements. As a result of the province's initiatives, Hydro One has identified 20 priority transmission expansion projects and is focusing on servicing renewable resource clusters. As of October 2010, the Ontario Power Authority (OPA) has received 1469 MW of FIT contracts executed for wind projects. A further 5953 MW of wind projects are awaiting approval. A Korean consortium is now planning to develop 2500 MW of renewable energy projects in the province. The OPA has also been asked to develop an updated transmission expansion plan. Transmission/distribution availability tests (TAT/DAT) have been established to determine if there is sufficient connection availability for FIT application projects. Economic connection tests (ECTs) are conducted to assess whether grid upgrade costs to enable additional FIT capacity are justifiable. When projects pass the ECT, grid upgrades needed for the connection included in grid expansion plans. Ontario's long term energy plan was also reviewed. tabs., figs.

  3. Ontario's energy crisis brings out conflicting visions

    International Nuclear Information System (INIS)

    Kishewitsch, S.

    2004-01-01

    Ontario's medium-term energy supply situation is discussed in light of the Ontario provincial government's insistence on phasing out coal-fired generation by 2007, and the somewhat longer term uncertainty about the aging nuclear fleet and the price tag associated with their overhauling or replacement. Centre to the discussion is the replacement of coal-fired plants by natural gas-fired generating plants, complicated by the fact is that there is already a surfeit of gas-fired plants sitting idle for lack of fuel available at an economically acceptable price. Recent statistics show that conventional gas supplies have already levelled off and unconventional sources, such as coalbed methane, and imports like LNG, are more abundant, but also significantly more expensive. The nuclear option is considered by knowledgeable insiders as a viable option for increased generation, although it is generally acknowledged as a serious public relations problem. The contributions of green power and cogeneration are also explored; the most optimistic estimates put the supply from this source at 50,000 GWh a year; less than the amount needed even in the absence of growth in demand. The overall conclusion is that Ontario's energy future can only be assured by aggressive pursuit of productivity improvements, financial and policy innovations, extensive use of cogeneration, strong development of renewables, energy conservation, efficiency, and demand management

    1987-11-01

    The fundamental objectives of this study were to review and improve the seismological data base as an aid in more realistic evaluation of seismic hazard in southern Ontario. For this purpose, the following procedures have been undertaken: In the first stage, the types of errors in earthquake location files are identified, sources of uncertainties are discussed and a sensitivity analysis of the errors to different parameters is presented. In the second stage, a group location technique, Joint Hypocenter Determination (JHD), has been utilized to improve the locations of a group of 67 well-recorded events, mostly from the more active region near the Ottawa River and in western Quebec. The third stage, to relocate smaller and less reliably detected events in southern Ontario, utilized a nw algorithm, 'HYPOCENTER', which proved very efficient and flexible in the test runs for handling local explosion and natural events. A preliminary interpretation of the seismicity patterns in the study regions shows that earthquakes of magnitude 3 and larger tend to align along preferred seismic trends which may, in turn, be controlled by weakness planes in the Earth's crust. These inferred trends coincide with dominant northwesterly and northeasterly striking structural directions. For earthquakes smaller than magnitude 4 prior to 1970 and for microearthquakes (M<3) which occurred near the Lake Ontario shoreline, the detection coverage was not sufficient to conclusively discuss accurate locations and causative mechanisms

  5. Climate change impacts: an Ontario perspective

    International Nuclear Information System (INIS)

    Mortsch, L.

    1995-11-01

    Significant changes in the climate system which are likely to affect biophysical, social and economic systems in various ways, were discussed. Trends in greenhouse gas levels show that during the 20. century, human activity has changed the make-up of the atmosphere and its greenhouse effect properties. A pilot study on the impacts of climate change identified changes in the water regime such as declines in net basin supply, lake levels and outflows, as important concerns. These changes would have impacts on water quality, wetlands, municipal water supply, hydroelectric power generation, commercial shipping, tourism and recreation, and to a lesser extent, on food productions. Climate impact assessments suggest that world conditions will change significantly as a result. Those with less resources are likely to be most affected by climate change, and the impacts on other regions of the world will be more significant to Ontario than the direct impacts on Ontario itself. In an effort to keep pace with global changes, Ontario will have to limit emissions, conduct research in innovative technology and develop greater awareness of the risk of climate change. refs., tabs., figs

    2016-01-01

    Benthic prey fishes are a critical component of the Lake Ontario food web, serving as energy vectors from benthic invertebrates to native and introduced piscivores. Since the late 1970’s, Lake Ontario benthic prey fish status was primarily assessed using bottom trawl observations confined to the lake’s south shore, in waters from 8 – 150 m (26 – 492 ft). In 2015, the Benthic Prey Fish Survey was cooperatively adjusted and expanded to address resource management information needs including lake-wide benthic prey fish population dynamics. Effort increased from 55 bottom trawl sites to 135 trawl sites collected in depths from 8 - 225m (26 – 738 ft). The spatial coverage of sampling was also expanded and occurred in all major lake basins. The resulting distribution of tow depths more closely matched the available lake depth distribution. The additional effort illustrated how previous surveys were underestimating lake-wide Deepwater Sculpin, Myoxocephalus thompsonii, abundance by not sampling in areas of highest density. We also found species richness was greater in the new sampling sites relative to the historic sites with 11 new fish species caught in the new sites including juvenile Round Whitefish, Prosopium cylindraceum, and Mottled sculpin, Cottus bairdii. Species-specific assessments found Slimy Sculpin, Cottus cognatus abundance increased slightly in 2015 relative to 2014, while Deepwater Sculpin and Round Goby, Neogobius melanostomus, dramatically increased in 2015, relative to 2014. The cooperative, lake-wide Benthic Prey Fish Survey expanded our understanding of benthic fish population dynamics and habitat use in Lake Ontario. This survey’s data and interpretations influence international resource management decision making, such as informing the Deepwater Sculpin conservation status and assessing the balance between sport fish consumption and prey fish populations. Additionally a significant Lake Ontario event occurred in May 2015 when a single

    To determine the prevalence rates and characteristics of past-year mental health consultation for Ontario's adult (18 + years old) immigrant populations. The Canadian Community Health Survey (CCHS) 2012 was used to calculate the prevalence rates of past-year mental health consultation by service provider type. Characteristics associated with mental health consultation were determined by carrying out multivariable logistic regression analysis on merged CCHS 2008-2012 data. Adult immigrant populations in Ontario (n = 3995) had lower estimated prevalence rates of past-year mental health consultation across all service provider types compared to Canadian-born populations (n = 14,644). Amongst those who reported past-year mental health consultation, 57.89% of Ontario immigrants contacted their primary care physician, which was significantly higher than the proportion who consulted their family doctor from Canadian-born populations (45.31%). The factors of gender, age, racial/ethnic background, education level, working status, food insecurity status, self-perceived health status, smoking status, alcohol drinking status, years since immigration, and age at time of immigration were significantly associated with past-year mental health consultation for immigrant populations. Ontario's adult immigrant populations most commonly consult their family doctor for mental health care. Potential exists for expanding the mental health care role of primary care physicians as well as efforts to increase accessibility of specialized mental health services. Integrated, coordinated care where primary care physicians, specialized mental health professionals, social workers, and community educators, etc. working together in a sort of "one-stop-shop" may be the most effective way to mitigate gaps in the mental health care system. In order to effectively tailor mental health policy, programming, and promotion to suit the needs of immigrant populations initiatives that focus on

    2004-01-01

    This report presents a resource assessment by the Independent Electricity Market Operator (IMO) for the 18-month period from April 2004 to September 2005. It is based on the IMO's forecast of electricity demand. The information was provided by power generators in Ontario. The outlook for the electricity system has improved due to the return to service of 3 nuclear units and the addition of more than 700 MW of generation. The return to service of the nuclear units has decreased Ontario's reliance on imports to help meet energy demand in the province. The shutdown of 1150 MW of coal-fired generation at Lakeview Thermal Generating Station in Mississauga emphasizes the importance of improving transmission and generation capacity in the Toronto area. This report also includes updated values for existing resource scenarios and planned resource scenarios. The reliability of Ontario's transmission system was also assessed along with the adequacy of the existing resource to meet the forecast demand. The existing installed generation resources include 5 nuclear stations generating 10,831 MW of electricity, 5 coal stations generating 7,564 MW of electricity, 22 oil and gas fired stations generating 4,364 MW of electricity, 61 hydroelectric stations generating 7,676 MW of electricity, and 2 other stations generating 66 MW of electricity. Although the existing resource scenario is better than in previous reports, imports will be required under extreme weather conditions to help meet electricity demand in Ontario during peak periods. 21 tabs., 10 figs

    1999-01-01

    The factors influencing the initial market pricing in the early years of Ontario's new electricity market were discussed with particular insight on the potential for near term development of independent power and cogeneration. The major factors influencing prices include: (1) no increase in retail prices, (2) financial restructuring of Ontario Hydro, (3) the Market Power Mitigation Agreement, (4) tighter power plant emissions standards, and (5) an electricity supply and demand balance. Generation competition is not expected to influence market pricing in the early years of the new electricity market. Prices will instead reflect the restructuring decisions of the Ontario government. The decision to have Ontario Power Generation Inc. (OPGI) as a single generator for Ontario Hydro's generation assets will ensure that average spot market pricing in the early market years will be close to a 3.8 c/kWh revenue cap

    2004-11-01

    In October 2004, the Environics Research Group conducted a telephone survey of 608 adult Ontarians to collect information on matters regarding energy; consumer confidence and protection; responsibilities of the Ontario Energy Board; and consumer information preferences. This report summarizes the key findings of the survey. According to the survey, the most important electricity and natural gas issue was identified as being price and cost issues, followed by reliability of supply, conservation, keeping utilities publicly owned, finding renewable sources of energy, and over-consumption. The survey revealed that Ontarians show much interest in conserving energy to save money, to protect the environment and ensure future energy supply, but they are generally sceptical that their interests are being protected on electricity and natural gas price issues. At least 9 in 10 Ontarians consider the tasks of the Ontario Energy Board to be important. The majority of Ontarians prefer to receive energy conservation information through the mail and from public regulators over a government department or a company. 10 tabs

The survey included telephone interviews with consumer groups, advocacy groups, the energy sector, electricity and gas distributors, financial organizations as well as other stakeholders. The topics addressed in the survey were key energy issues and priority issues; the perceived role of the OEB; the OEB strengths and weaknesses; the importance of various OEB functions; the overall performance of the OEB; an evaluation of OEB communication with industry and consumers; an evaluation of service quality; and, awareness and participation in regulatory policy initiatives. Respondents used a 10-point scale in their evaluation. This report presented the main findings and their interpretations. Major stakeholders identified electricity supply issues and the price of electricity as being the most important energy issues facing Ontario. This report also presented the detailed findings for questions regarding the lack of generator capacity, policy stability, the coal phase out program, electricity blackouts, conservation, electricity restructuring and investment. The major finding of the survey was an overall increase in satisfaction with the OEB's performance. It was suggested that the OEB can improve in timeliness and providing consumer information. The major areas of strength were found to be its professionalism in conducting hearings and the fairness of the Board's decisions and regulations. tabs

  2. Municipal utilities vs Ontario Hydro ownership of transmission stations

    International Nuclear Information System (INIS)

    In Ontario, the ownership of transformer stations is an area of debate for two reasons. Municipal utilities are solely concerned with supply to their own customers while Ontario Hydro bases its planning and construction on the most inexpensive power rates for the province as a whole. An underbuilding of the transmission system in the 1980s due to low load forecasts has resulted in low capacity in fast-growing municipalities such as Vaughan. The town of Vaughan commissioned its first 230-kV transformer station in June 1989 and will build more if its current growth rate of ca 17% continues. Ontario Hydro levies transformation costs on power sold to municipal utilities, which are eliminated if the municipal utility owns the transformer station. A large municipality that pays as much as $600,000/y in transformation costs could reduce these costs by up to 25% by owning its own station. Costs for such stations are lower for municipalities because they only pay costs of existing technology, can construct using non-union labor, and can build to lower standards than Ontario Hydro. In addition, owning their own stations can give municipalities a flexibility that Ontario Hydro may not have in the case of a large customer moving into a given area. Municipalities also have shorter-term planning timeframes than Ontario Hydro's 8-10 years for transmission systems. The Municipal Electrical Association is in the process of finalizing an agreement with Ontario Hydro to address the ownership question. 1 fig

    Essential oils, such as camphorated and eucalyptus oils, are volatile oils that can be absorbed by mouth and through the skin; if ingested orally by children, they can be harmful, even life-threatening. To determine the frequency of essential oil ingestion among children in Toronto, Ontario. Charts from December 1995 through March 1997 at the Ontario Regional Poison Information Centre, The Hospital for Sick Children, Toronto were reviewed to collect information on calls about essential oil ingestion, and a search of MEDLINE articles from 1966 to 1998 was conducted using the key words: 'camphor', 'eucalyptus', 'paediatric', and 'poisoning'. Callers to the Poison Information Centre reported that 251 children had ingested an essential oil or product: eucalyptus oil 50 children; camphorated oil 18 children; VapAir (Drug Trading, Canada) vaporizing liquid 93 children; and Vicks VaporRub (Procter & Gamble, Canada) 90 children. The most common symptoms were cough, vomiting and cough associated with vomiting. Two children had seizures but recovered. The MEDLINE search found 18 reports of paediatric ingestion of the oils or oil products. The main symptoms were vomiting, lethargy, coma and seizures. One child died. Although widely used by health care consumers, essential oils and the products that contain them can be harmful when ingested by children. Further education for parents and other caregivers about the risks involved in exposure to these products is required.

    This paper presents Ontario Energy Board's implementation plan to install 800,000 smart meters by December 31, 2007. The objective is to help consumers control their electricity bills through conservation and demand response. The three conditions that will change power consumption habits are price changes in response to demand and supply forces; the ability of consumers to see and respond to the price signals; and, a measurement of the response so that consumers get credit for their actions. This paper identifies the mandatory technical requirements for smart meters and the support operations of distributors. It sets priorities, identifies barriers and regulatory mechanisms for cost recovery. It also discusses options for ownership of the meters. 18 refs., 1 tab., 2 figs

  6. Feminism and women's health professions in Ontario.

    Historically, prevailing gender ideologies were an important element in both the exclusionary strategies employed by male occupational groups and the countervailing responses by female groups. The way in which evolving gender ideologies, and feminism in particular, influence the continuing struggle for greater status and recognition by female professions, however, remains to be fully explored. In this paper, we examine the impact and the role of feminism and feminist ideologies within three female professional projects: nursing, dental hygiene and midwifery in Ontario. We argue that feminism provides an ideology of opposition that enables leaders in these professions to battle against professional inequalities by laying bare the gender inequalities that underlie them. Framing their struggles in feminist terms, female professions also seek recognition for the uniquely female contribution they make to the health care division of labour. At the same time, there exists a tension between ideals of feminism and ideals of professionalism, that has the potential to undermine female professional projects.

  7. Ontario Hydro nuclear - challenges of the future

    International Nuclear Information System (INIS)

    Field, R.

    1996-01-01

    The challenges facing Ontario Hydro Nuclear (OHN), as understood at the time of the conference, are discussed. OHN had many strengths to build on in preparing for the competition ahead, including: extremely competitive production costs, strong technical capabilities, advantages of multiple units, environmental advantages favoring nuclear, strong public support, and improving station performance. Even with these advantages, OHN faced the difficult challenge of improving overall performance in the face of a large debt burden, coupled with the reinvestment demands of aging units at Pickering A and Bruce A. At the time of the conference, Bruce 2 had already been shut down, because the cost of retubing it and replacing its boilers could not be justified. The ''drive to nuclear excellence'' involves the simultaneous achievement of top performance in safety, reliability and cost; and to this end, changes were being made to reverse the trends indicated by disappointing ''peer reviews''

    The objectives of this study were to describe the routine use of analgesics by Ontario veterinarians for common surgeries in dogs and cats, and to compare routine use of analgesics between species and surgeries, using Chi-square analyses. In total, 239 veterinarians responded to the questionnaires; a response rate of 13.1%. Fifty-two percent to 79% of veterinarians used meloxicam for both species and all surgeries. Approximately 9% of veterinarians did not use analgesics for dog ovariohysterectomy and castration, while 16% to 22% did not use analgesics for these surgeries in cats. Veterinarians used and dispensed analgesics to dogs more often than to cats ( P veterinarians administered analgesics pre-emptively to both dogs and cats for all surgeries. Continuing education for veterinarians needs to focus on understanding of pre-emptive analgesia, preventive analgesia, and the importance of dispensing analgesic drugs after surgery for all surgeries.

    The freight (cargo) transportation sector accounts for a major use of fossil fuels and contributes significantly to greenhouse gas emissions. A study was conducted to assess the prospects, in terms of CO 2 emission reduction, of alternatives to present freight distribution, especially alternatives involving the use of rail instead of truck. Statistical data for Ontario freight transportation were analyzed for fuel consumption, CO 2 emission and cost consequences. Railway fuel consumption was calculated for detailed routing descriptions using a model that computed route and service specific fuel use. The information was compared directly with truck fuel consumption. It was determined that shippers who needed quick, accurately timed shipments preferred trucking over rail, while price conscious shippers, or those with heavy loading commodities preferred rail. An important goal of the study was to identify the enormity of the challenges involved, and clarify the potential tradeoffs by showing different strategies, with respect to CO 2 reduction and related economic impacts. refs., tabs., figs

  10. Forecasting Ontario's blood supply and demand.

    2012-02-01

    Given an aging population that requires increased medical care, an increasing number of deferrals from the donor pool, and a growing immigrant population that typically has lower donation rates, the purpose of this article is to forecast Ontario's blood supply and demand. We calculate age- and sex-specific donation and demand rates for blood supply based on 2008 data and project demand between 2008 and 2036 based on these rates and using population data from the Ontario Ministry of Finance. Results indicate that blood demand will outpace supply as early as 2012. For instance, while the total number of donations made by older cohorts is expected to increase in the coming years, the number of red blood cell (RBC) transfusions in the 70+ age group is forecasted grow from approximately 53% of all RBC transfusions in 2008 (209,515) in 2008 to 68% (546,996) by 2036. A series of alternate scenarios, including projections based on a 2% increase in supply per year and increased use of apheresis technology, delays supply shortfalls, but does not eliminate them without active management and/or multiple methods to increase supply and decrease demand. Predictions show that demand for blood products will outpace supply in the near future given current age- and sex-specific supply and demand rates. However, we note that the careful management of the blood supply by Canadian Blood Services, along with new medical techniques and the recruitment of new donors to the system, will remove future concerns. © 2012 American Association of Blood Banks.

  11. Ontario's new sound guidelines and wind energy

    Feilders, J.

    2005-01-01

    Sound and vibration are considered to be pollutants. This paper provides an outline of sound guidelines and their relationship to wind energy and Ontario's Environmental Protection Act, which prohibits the discharge of noises that cause or are likely to cause adverse effects. Certificates of approval are needed for wind turbine generators. The approval process is detailed in this paper, referring to existing limits in urban and rural areas, with sound level limits being based on the source producing the same sound level as background ambient sound levels. Background sound levels included traffic and nature as well as wind. For wind turbines, the ambient is related to the wind induced level by adding 7 decibels to the wind induced background sound level in exposed areas. Points of reception are considered to be locations outdoors where a person may be exposed to the sound or the plane of an exterior door or window of a room in which a person may be exposed to the sound, where the door or window is open. Sound limits apply within a distance of 30 m from a dwelling or camping area in a rural area, with the exception being dwellings on the premises of the wind energy facility. Certificate of Approval report requirements are also necessary and must include test results of turbines proposed in terms of sound power at the operating speeds to be used, as well as calculations of sound levels at points of reception, using an ISO 9613 sound propagation model. It is stated that there are no requirements to conduct an acoustic audit after the wind farm is in operation, should no complaints arise. Noise waivers are not supported by the Ontario Ministry of Energy. However, it was noted that the wind power industry are free to pursue this matter on a political level. tabs., figs

    A freighter in the process of loading rock for the Quebec Iron and Titanium Mining Company near Havre-St. Pierre on the extreme north shore of the St. Lawrence River, was suddenly tossed against the dock by rough waters on the night of March 23, 1999, and spilled 49 tonnes of bunker fuel oil into the river. This article describes how the crew of the ship, trained by Environmental Accident Protection Inc., based in Petrolia, Ontario, averted disaster by responding to the accident quickly and effectively. Their first action was to notify the appropriate environmental and regulatory authorities and to put in place containment booms which corralled about 17 tonnes of oil. The oil contained by the booms were removed by trained personnel under the guidance of Eastern Canada Response Corporation of Corunna, Ontario, and Response Systems Inc. of Neshanic, New Jersey, in approximately three hours with only minimum disruption to the environment. Further cleanup of the area, often hindered by bad weather, freezing rain, ice, and 100 km/hr winds, was done by the cooperative efforts of governments, industry and the local fishermen's association. The work included scrubbing the shore with wire brushes and scrapers and handbathing some 1000 migratory birds. The cleanup job was completed in about three weeks and the Mingan Archipelago National Park Reserve and other nearby habitats for migrating birds were saved the devastation that would have occurred, except for the quick and knowledgeable intervention of a trained crew and an outstanding example of public-private sector and community cooperation. 2 photos

  13. The Devran Petroleum story: Nice idea, now what?

    International Nuclear Information System (INIS)

    Cowan, J.F.

    1993-01-01

    The history of the Devran petroleum company is reviewed. The company began in Ontario in 1982 and its first venture, a 50% partnership with Shell Canada, was to excavate two drilling rooms 430 ft into the depleted Sarnia-London (Ontario) oil field and drill 11 horizontal wells to obtain oil production. This venture produced very little crude and was abandoned due to excessive water inflow. Devran's next initiative was to purchase the Ontario government's share in Onexco Oil and Gas, which had a number of Ontario properties and eight wells. The high netbacks per bbl characteristic of Ontario reservoirs enabled Devran to survive and pay off loans for the Onexco purchase, and the number of Devran's Ontario wells rose to over 50. Devran then acquired a Toronto Stock Exchange listing and bought a 23% interest in the Pelican Lake horizontal drilling project in western Canada. This project was successful and is still continuing at a maximum production rate of 2,000 bbl/d. The company then bought into other successful partnerships in Saskatchewan and began a gas exploration project in Western Alberta with NuGas Ltd. as the operator. Devran's total oil production is currently ca 1,400 bbl/d and netbacks are ca $10.40/bbl, higher than the industry average of $8.82/bbl. Its market capital is ca $30 million and it trades at a market price equal to net asset value

    Financial information from Esso Imperial Oil, one of Canada's largest producers of crude oil and natural gas, was presented and a review of their 2002 operations was made available for the benefit of shareholders. Some of the highlights of 2002 are: the total return on Imperial shares including capital appreciation and dividends was 3 per cent, compared with a net loss of 12 per cent for the Standard and Poors/TSX composite index; in the past decade, the total return on Imperial's shares have averaged 17 per cent a year, compounded; regular dividend payments increased to 84 cents a share, the eighth consecutive year of dividend growth; and, the company has purchased more than 200 million shares for $5.2 billion since 1995, reducing the number outstanding by 35 per cent. Progress in key priority areas for 2002 included a second-best year for safety performance, a successful $1.6 billion capital investment program, the expansion of the Cold Lake oil sands project, an increase of 15 per cent in polyethylene production, an increase of 3.5 per cent in retail sales of Esso gasoline, and advancement of the Mackenzie gas project. Other achievements included the development of a 170 megawatt cogeneration plant at Cold Lake that will reduce costs and greenhouse gas emissions. A 95 megawatt unit was also constructed at the Sarnia manufacturing facility. This report summarized the company's energy resource activities and presented an operations review as well as consolidated financial statements, and common share information including the accounts of Imperial Oil Inc. and its subsidiaries and the company's proportionate share of the assets, liabilities, revenues, expenses and cash flows of joint ventures. Revenue and expenditure statements were summarized by source. tabs., figs

  15. Why we must move quickly to open Ontario's power market

    2001-01-01

    This paper presented issues regarding the reform in Ontario's electricity sector and why the Independent Power Producer's Society of Ontario (IPPSO) believes it is necessary to open the electricity market in the province as soon as possible. The 400 members of IPPSO include developers, suppliers, consultants and various professionals working in the fields of co-generation, small hydro, biomass, wind energy and other technologies with a total generating capacity of about 1600 MW in Ontario. The government of Ontario recently announced four principles for implementing competition in the electricity sector which were protecting the consumers and offering choice, creating a strong business climate, protecting the environment, and supporting innovation and alternative energy development. This paper described the possible indicators of success in implementing these four principles and provided a historical perspective on the motivation for bringing in competition

  16. Full cost accounting for decision making at Ontario Hydro

    International Nuclear Information System (INIS)

    Plagiannakos, T.

    1996-01-01

    Ontario Hydro's approach to full cost accounting (FCA) was outlined in response to questions raised earlier, in another forum, regarding Ontario Hydro's views on FCA. FCA was defined as an evaluation framework (as opposed to an accounting system) which tries to account for the internal (private) as well as the external (environment and human health) costs and benefits and integrate them into business decisions. When the external impacts cannot be monetized, qualitative evaluations are used based on the damage costing approach, which Ontario Hydro prefers to the cost of control method recommended by its critics. In general, however, Ontario Hydro is not opposed to FCA in so far as it puts the Utility in a better position to make more informed decisions, improve environmental cost management, avoid future costs, enhance revenue, improve environmental quality, contribute to environmental policy, and contribute to sustainable development. 1 fig

    1987-01-01

    Ontario has an excellent conceptual plan to ensure the safety of its inhabitants in the event of a nuclear accident anywhere in the world. This plan still needs to be translated into tangible preparedness to deal with such an emergency. The province is confident that, with the assistance of Ontario Hydro, a high level of nuclear emergency preparedness will soon be established for the people of the province

  20. New rules for competition: Ontario to cap power plant emissions

    International Nuclear Information System (INIS)

    Anon.

    1999-01-01

    The Ontario government through the Dept. of the Environment announced on November 16, 1999 that it would cut the emissions from Ontario coal burning power plants that cause acid rain and smog. This announcement was a much anticipated clarification of the government's plans to clean up the power industry since the enactment of the Electricity Competition Act more than one year past. The announcement signals the beginning of a public discussion process between government and stakeholders on the environmental rules for electricity generation in Ontario. The Ontario government is expected to release draft regulations for controlling coal burning power plant emissions in the near future. Consulations with stakeholders on the regulations, as well as the rules for disclosure and labeling, are anticipated to begin in a few months. The announcement set out four principles for environmental performance in the competitive electricity market. Anti-smog requirements will be included in the stringent environmental requirements to be built into Ontario's new, competitive electricity market. The strong measures which the government will put into place when the market opens later in 2000 include: (1) regulations to cut smog and acid gas emissions for all Ontario electricity generators on the grid - these regulations will include Ontario Hydro's voluntary nitrogen oxide limits; (2) emission performance standards to define maximum acceptable emission levels for all generators wanting to sell in the Ontario market; (3) a framework to support opportunities to make greater use of more efficient, environmentally responsible technologies; and (4) disclosure requirements to ensure that electricity consumers can understand the environmental implications of their purchasing decisions

  1. Cross currents : hydroelectricity and the engineering of northern Ontario

    International Nuclear Information System (INIS)

    Manore, J.L.

    1999-01-01

    The history of hydroelectric development in northern Ontario was reviewed and analysed with special emphasis on the developments along the Mattagami and Abitibi Rivers. The objective was to examine the important factors that shaped modern hydroelectric development in Canada. System builders, the privately owned Nesbitt Thomson Company, the publicly owned Hydro Electric Power Corporation of Ontario and the eventual evolution of the single power system under Ontario Hydro are chronicled. Broad historical themes such as the technological impacts, regionalism, indigenous rights, plus environmental and economic issues are examined, in addition to an appreciation of the importance of electricity in the manufacturing sector of Ontario, the impact of hydroelectric development on the northern environment and on the northern First Nations, who rely on rivers for their subsistence. Until fairly recently, government policies and interpretations of law often excluded the recognition of Aboriginal uses of river systems, thereby limiting First Nations' peoples ability to practice traditional ways of life. In essence, the book is an account of how the northeastern power system in Ontario shaped the social, political and natural environments and how the development of northeastern power sources by southern power developers shaped the regional interactions between Ontario's north and south. refs., figs

  2. Design, construction and operation of Ontario Hydro's CANDU plants

    International Nuclear Information System (INIS)

    Campbell, P.G.

    1981-06-01

    Ontario Hydro has been producing electricity commercially from nuclear power since 1968, using CANDU reactors which have proved enormously successful. The 206-MW Douglas Point station, nearly 10 times larger than the first Canadian power reactor, NPD-2, resulted from a cooperative effort between Atomic Energy of Canada Ltd., the provincial government of Ontario, and Ontario Hydro. This approach led to a basic working relationship between the parties, with Ontario Hydro acting as project manager and builder, and AECL acting as consultant with respect to the nuclear components. Before Douglas Point was fully commissioned Ontario Hydro was ready to commit itself to more nuclear stations, and work was started on the four-unit Pickering nuclear generating station. Multi-unit stations were adopted to achieve economies of scale, and the concept has been retained for all subsequent nuclear power plants constructed in the province. The organization of Ontario Hydro's project management, construction, and operation of nuclear generating stations is described. Performance of the existing stations and cost of the power they produce have been entirely acceptable

    2003-01-01

    The Ontario Chamber of Commerce conducted a survey for its members between August 19-23, 2003 to determine the impact of the massive power failure that took place on August 14, 2003. This paper presents the results of the survey which are based on a total of 929 respondents across Ontario. The primary businesses that participated in the survey were: manufacturing, service, technology, commercial, retail, automotive, steel, forestry, and resource businesses. 78 per cent of the respondents replied that the power disruption had a negative impact on their business. 48 per cent of the respondents were without power for 11-24 hours. 65 per cent of the businesses did not have a blackout contingency plan in place, but 63 per cent responded that they will likely develop a plan for future power failures. The survey also asked business members how they would rate the federal, provincial and municipal government's response to the emergency. The participants ranked the top 3 actions that governments can take to prevent future outages as follows: (1) review possible changes to the interconnected grid system, (2) ensure sufficient supply within Ontario, and (3) invest in alternative forms of energy such as solar and wind power. Other recommendations were to implement a sliding scale of energy pricing to reflect the true cost of energy. It was suggested that tax incentives should be offered to encourage energy conservation and the use of alternative energy sources. 2.6 per cent of the respondents suggested that excess energy should not be sold to neighbouring jurisdictions. 1 tab., 6 figs

  6. Expanding exports, increasing smog : Ontario Power Generation's and Hydro One's strategies to continue coal-fired electricity generation in Ontario

    International Nuclear Information System (INIS)

    Gibbons, J.

    2002-06-01

    The production of coal-fired electricity increased by approximately 150 per cent in Ontario between 1995 and 2000. As a result, the smog-causing emissions generated by the five coal-fired power plants operated by Ontario Power Generation caused an increase in smog and worsened air quality in the province as well as affecting air quality as far afield as the Atlantic provinces. Between 2002 and 2005, it is expected that the Pickering and Bruce nuclear plants will be returned to service, making the electricity generated by the coal plants surplus to Ontario's needs. Increasing this surplus are the planned natural gas generating stations. Ontario Power Generation is planning on using this surplus to export it to the United States rather than phasing out its reliance on coal. The increase in exports to the United States Northeast and Midwest is planned with Hydro One, already busy increasing its transmission capacity to the United States by 1,000 megawatt (MW). This plan involves laying 975 MW submarine cable from the Nanticoke Generating Station (operated by Ontario Power Generation) under Lake Erie to Pennsylvania, Ohio, or both states. At the moment, the exports are constrained by the government emissions limits imposed by the Ontario government on sulphur dioxide and nitrogen oxides. This constraint could be removed if Ontario Power Generation decides to pay further for pollution controls for sulphur dioxide and nitrogen oxides at its coal stations. Unfortunately, increasing the exports would also result in emissions increases for 28 other uncapped pollutants such as lead, mercury and arsenic. The author recommended that the Ontario government ban non-emergency coal-fired electricity exports to improve air quality in the province. refs., 8 figs

    1991-01-01

    It is generally recognized that the Chernobyl Unit 4 accident did not reveal any new phenomena which had not been previously identified in safety analyses. However, the accident provided a tragic reminder of the potential consequences of reactivity initiated accidents (RIAs) and stimulated nuclear plant operators to review their safety analyses, operating procedures and various operational and management aspects of nuclear safety. Concerning Ontario Hydro, the review of the accident performed by the corporate body responsible for nuclear safety policy and by the Atomic Energy Control Board (the Regulatory Body) led to a number of specific recommendations for further action by various design, analysis and operation groups. These recommendations are very comprehensive in terms of reactor safety issues considered. The general conclusion of the various studies carried out in response to the recommendations, is that the CANDU safety design and the procedures in place to identify and mitigate the consequences of accidents are adequate. Improvements to the reliability of the Pickering NGSA shutdown system and to some aspects of safety management and staff training, although not essential, are possible and would be pursued. In support of this conclusion, the paper describes some of the studies that were carried out and discusses the findings. The first part of the paper deals with safety design aspects. While the second is concerned with operational aspects

  9. Reclamation of acidified lakes near Sudbury, Ontario

    Scheider, W.; Adamski, J.; Paylor, M.

    1975-01-01

    As part of the ministry of the Environment Lake Reclamation Program, Ca(OH)/sub 2/ and CaCO/sub 3/ were used to artificially offset acidic conditions, re-establish buffer systems and reduce heavy metal levels in two low pH lakes near Sudbury, Ontario. Middle and Lohi lakes were treated in the fall of 1973 and monitoring continued into 1975. The lakes upstream of each treated lake, Hannah and Clearwater respectively, were monitored as controls. It was determined that a combination treatment (CaCO/sub 3/ plus Ca(OH)/sub 2/ as opposed to Ca(OH)/sub 2/ only) provided a more stable buffer system and maintained improved water quality for a longer period of time. Microbial and phytoplanktonic populations showed a positive response to treatment, increasing in standing stock. Zooplanktonic and zoobenthic populations decline, probably due to the lethally rapid pH change. Numbers are expected to increase in future in response to the improved water conditions and increased food availability.

  10. Heat wave generates questions about Ontario's generation capacity

    International Nuclear Information System (INIS)

    Horne, D.

    2005-01-01

    Concerns regarding Ontario's power generation capacity were raised following a major blackout which occurred in August 2003. Power demand reached 26,170 MW during the weeks leading to the blackout, forcing the Independent Electricity System Operator (IESO) to ask residents to reduce electricity use during the day. The grid operator had also issued a forecast that Toronto could face rolling blackouts during times of heavy power demand. Ontario power consumption records were set in June and July of 2003 due to a heat wave, with hourly demand exceeding 25,000 MW on 53 occasions. Ontario was forced to import up to 3,400 MW (13 per cent of its power needs) from neighbouring provinces and the United States. During that period, the price of power had risen sharply to over 30 cents a kilowatt hour, although household consumers were still charged in the 5 to 10 cent range per kilowatt hour. However, it was noted that taxpayers will eventually bear the cost of importing power. The IESO noted that importing electricity is cheaper than the generation available in Ontario and that it is more economical to import, based on the market clearing price of all generators. In 2004, the IESO purchased 6 per cent of their electricity from the United States. That figure is expected to increase for 2005. Ontario generators produced 26.9 million MWh more in the summer of 2005 than during the same period in 2004 to meet electricity demand levels. It was noted that although importing power presently meets peak demand, the IESO agrees there is a need for new generation within Ontario. In addition to restarting Ontario's Pickering and Bruce nuclear facilities, more than 3,300 MW of new gas-fired generation is under construction or approved, and more than 9,000 MW are in various stages of approval. This paper discussed the effect of high energy costs on industry and Ontario's ability to meet future electricity demand in comparison to neighbouring jurisdictions.

  11. Electricity market price volatility: The case of Ontario

    International Nuclear Information System (INIS)

    Zareipour, Hamidreza; Bhattacharya, Kankar; Canizares, Claudio A.

    2007-01-01

    Price volatility analysis has been reported in the literature for most competitive electricity markets around the world. However, no studies have been published yet that quantify price volatility in the Ontario electricity market, which is the focus of the present paper. In this paper, a comparative volatility analysis is conducted for the Ontario market and its neighboring electricity markets. Volatility indices are developed based on historical volatility and price velocity concepts, previously applied to other electricity market prices, and employed in the present work. The analysis is carried out in two scenarios: in the first scenario, the volatility indices are determined for the entire price time series. In the second scenario, the price time series are broken up into 24 time series for each of the 24 h and volatility indices are calculated for each specific hour separately. The volatility indices are also applied to the locational marginal prices of several pricing points in the New England, New York, and PJM electricity markets. The outcomes reveal that price volatility is significantly higher in Ontario than the three studied neighboring electricity markets. Furthermore, comparison of the results of this study with similar findings previously published for 15 other electricity markets demonstrates that the Ontario electricity market is one of the most volatile electricity markets world-wide. This high volatility is argued to be associated with the fact that Ontario is a single-settlement, real-time market

    Howe, W.

    1987-09-01

    This field guide consists of two parts. Part I deals with the packages used by Ontario Hydro for shipment of its radioactive materials. Highly radioactive material must be transported in rugged containers which will survive a severe transportation accident. These containers are known at Type B Packages. Each container used by Ontario Hydro for shipments of highly radioactive material has been allotted a single page in this field guide with specific information for quick reference. Each package identification card includes a description of the package and contents and the required safety marking. Photographs of both the container and the vehicle as well as a cross-sectional diagram will assist Ontario Hydro personnel as well as emergency response personnel in quick identification of containers and contents. Containers used for transportation of material will low levels of radioactivity are also briefly discussed. These containers could fail in the event of an accident but the radioactivity is limited to low levels. Part I of this field guide also summarizes general emergency response instructions which are applicable to any transportation accident involving a package with radioactive material. Part II of this field guide provides information about the requirements which must be met by Ontario Hydro prior to any shipment of radioactive material in Ontario

  13. Fifteen years of radioactive waste management at Ontario Hydro

    1985-01-01

    Ontario Hydro is a large Canadian utility producing 84% (7394 MWe) of the Nuclear Electricity generated in Canada. The low- and intermediate-level radioactive wastes generated by the Ontario Hydro program are currently being managed at the Bruce Nuclear Power Development with various volume reduction, packaging and interim storage systems. Ontario Hydro also owns and operates a radioactive waste transportation system. Studies are in progress for final disposal of these wastes in a suitable geology in Ontario. Since its inception in 1971, Ontario Hydro's radioactive waste management program has evolved into providing a full fledged radioactive waste management capability to the utility's two nuclear generation centres at Pickering and Bruce, and later in the decade, to Darlington. This paper summarizes the various developments in this program; highlights the major facilities both in-service and planned to be built; reviews the experiences gained over fifteen years of in-house waste management; and discusses the proposed reorientation towards ultimate disposal of these wastes. 2 refs., 8 figs., 1 tab

  14. Selling from Ontario into the U.S. midwest

    International Nuclear Information System (INIS)

    Green, B.

    2002-01-01

    The market structure of the Midwest Independent System Operator (MISO) for the electric power grid was described with reference to physical bilateral markets, multi-control areas, and MISO services such as security coordination, congestion management, billing, generator interconnections, tariff administration, energy imbalance, market monitoring, and electronic scheduling. The drivers impacting MISO development include MISO-PJM-SPP common market initiative, the FERC Standard Market Design initiative, the integration of alliance companies with MISO, and the division of functional responsibilities between RTOs and ITCs. The characteristics of the Michigan market were described, along with participation in the midwest (Ohio and Michigan) wholesale and retail markets. It was noted that in order for Ontario to sell to the midwest, the Ontario market design would need a successful export bid each hour to get power out of the province. Sales of ancillary services from Ontario-based generation are not permitted in the initial Ontario market design. Energy and transmission is currently bundled in Ontario tariffs. 1 fig

    2005-01-01

    The potential contribution of solar energy to Ontario's electricity supply was evaluated in this PowerPoint presentation. Only 3.5 per cent of Canada's photovoltaic (PV) systems are connected to the electricity grid. However, 47 per cent of all homes in Ontario have the potential to install 3 kW PV arrays, and the solar industry has the potential to achieve growth rates of between 50 to 75 per cent, with medium term sustainable growth estimated at 30 to 40 per cent annually. The benefits of grid-connected solar energy include employment and wealth creation in Ontario; reductions in peak demand; and improved grid efficiency. It was noted that the price of solar PV is declining. Various market niches for solar energy technologies were outlined, and the targeting of early adopters was recommended as a first market for PV growth. An overview of the value of PV build-ups in California was presented, as well details of international tariffs and rates. A 10 year program leading to the installation of 15,000 PV systems or 40 MWp of installed capacity in Ontario by 2015 was outlined, as well as a plan for solar financing. It was concluded that priming the market now will mean that solar will be prepared to contribute to Ontario's supply during the 2015-2025 period, when its price will be competitive. refs., tabs., figs

    2007-06-01

    This paper describes a study that explores the experiences of internationally educated nurses (IENs) in their efforts to gain entry to practice as Registered Nurses (RNs) in the province of Ontario, Canada. The aim was to uncover, in part, the issues related to professional nursing credentialling. This study was guided by a biographical narrative (qualitative) research methodology. A convenience sample of 12 IEN students volunteered for this study representing the Philippines, Mainland China, Korea, Ukraine and India. The findings were that the IENs progress through a three-phase journey in their quest for licensure in Ontario. These phases include: (1) hope - wanting the Canadian dream of becoming an RN in Ontario; (2) disillusionment - discovering that their home-country nursing qualifications do not meet Ontario RN entry to practice; and (3) navigating disillusionment - living the redefined Canadian dream by returning to nursing school to upgrade their nursing qualifications. Professional regulatory nursing bodies and nursing educators, as well as practising nurses, must be aware of the potentially confusing and unpleasant processes IENs go through as they qualify for the privilege of practising nursing in Ontario.

    Results of an initial study indicated that the most significant factor affecting retention for Physiotherapists in Northern Ontario was perceived opportunity for career development. A follow-up study was completed two years later to determine: 1) actual job turnover and regional attrition among physiotherapists in Northern Ontario; and 2) the predictive validity of variables identified in the first study regarding job turnover and regional attrition. Job turnover occurred in 29.5% of those sampled and the regional attrition rate was 12%. Discriminant function analysis revealed factors affecting job turnover and regional attrition including professional experience, practice location, opportunity for career development and size of community of residence. Based on previous intention, indicated by participants, follow-up revealed that the initial study correctly predicted 77.5% of those who changed their jobs and 74.1% of those who left Northern Ontario. Identified factors provide direction for the development of strategies for recruitment and retention of physiotherapists.

    2017-07-01

    The province of Ontario continues to experience measles virus transmissions despite the elimination of measles in Canada. We describe an unusual outbreak of measles in Ontario, Canada, in early 2015 that involved cases with a unique strain of virus and no known association among primary case-patients. A total of 18 cases of measles were reported from 4 public health units during the outbreak period (January 25-March 23, 2015); none of these cases occurred in persons who had recently traveled. Despite enhancements to case-patient interview methods and epidemiologic analyses, a source patient was not identified. However, the molecular epidemiologic analysis, which included extended sequencing, strongly suggested that all cases derived from a single importation of measles virus genotype D4. The use of timely genotype sequencing, rigorous epidemiologic investigation, and a better understanding of the gaps in surveillance are needed to maintain Ontario's measles elimination status.

  20. The short-term impact of Ontario's generic pricing reforms.

    Directory of Open Access Journals (Sweden)

    Michael R Law

    Full Text Available Canadians pay amongst the highest generic drug prices in the world. In July 2010, the province of Ontario enacted a policy that halved reimbursement for generic drugs from the public drug plan, and substantially lowered prices for private purchases. We quantified the impact of this policy on overall generic drug expenditures in the province, and projected the impact in other provinces had they mimicked this pricing change.We used quarterly prescription generic drug dispensing data from the IMS-Brogan CompuScript Audit. We used the price per unit in both the pre- and post-policy period and two economics price indexes to estimate the expenditure reduction in Ontario. Further, we used the post-policy Ontario prices to estimate the potential reduction in other provinces.We estimate that total expenditure on generic drugs in Ontario during the second half of 2010 was between $181 and $194 million below what would be expected if prices had remained at pre-policy level. Over half of the reduction in spending was due to savings on just 10 generic ingredients. If other provinces had matched Ontario's prices, their expenditures over during the latter half of 2010 would have been $445 million lower.We found that if Ontario's pricing scheme were adopted nationally, overall spending on generic drugs in Canada would drop at least $1.28 billion annually--a 5% decrease in total prescription drug expenditure. Other provinces should seriously consider both changes to their generic drug prices and the use of more competitive bulk purchasing policies.

    This paper describes how the Collective Impact framework facilitated the design, implementation and development of a quality improvement initiative aimed at changing the way healthcare is provided to older adults living with mental health, addictions, neurocognitive and behavioral issues in southwestern Ontario. By promoting a common agenda, shared measurement systems, mutually reinforcing activities, continuous communication and with leadership from a backbone organization, system-wide change occurred. Outcomes, operational/strategic, clinical, capacity enhancement and community support structures as well as challenges are discussed. Improved coordination with primary care will further support enhanced clinical activities and capacity development strategies. Large-scale, multisectoral change is possible when aligned with a collaborative, problem-solving framework that promotes the commitment of many service providers/agencies to a common agenda.

    Energy Technology Data Exchange (ETDEWEB)

    1989-09-19

    This technical report was assembled by the Ontario Petroleum Institute as a source document for the discussion of the environmental issues which now confront the industry. The purpose of the report is to provide technical information to government about the nature of current practice, to inform industry on existing regulations and to promote discussion between government and industry. Oil drilling, production and stimulation are discussed. The material in a drilling pit usually separates into a liquid and a slurry phase. The liquid phase in a drilling pit contains the drilling fluid, formation water, rainfall, crude oil, surfactant, and soluble drilling additives. Drilling slurry contains rock cuttings, cement chips, clay, bentonite. The total volume of solids generated was estimated at 6,500m{sup 3} in 1988. Oilfield brine consists of formation water with minor quantities of soluble chemicals. The total volume of oilfield brine produced in 1988 was estimated at 1.308 million m{sup 3}. The total volume of stimulation fluids generated in 1988 was estimated at 1.264 m{sup 3} (8,000 barrels). It as recommended that operators and contractors take responsibility to avoid the use of material which are likely to become registerable wastes; that industry meet with regulatory authorities to discuss disposal standards, procedures and guidelines and to solve jurisdictional conflicts between regulatory bodies. It was also recommended that landfill operators be kept better informed about the nature and quantity of materials being disposed.

  13. Deregulation and the Alberta experience : the implications for Ontario

    International Nuclear Information System (INIS)

    Desrochers, J.P.

    2002-01-01

    An overview of the first year of electric power industry deregulation in Alberta was presented. The way in which electricity is bought and sold in Ontario and throughout North America is changing. Costs are no longer fixed and regulated. Electricity is becoming a commodity with high levels of price volatility. The paper presented hedging options for Alberta consumers, contracting lessons, market issues and lessons for Ontario. A comparison of Alberta's deregulation schedule with that of Ontario's was included. One year after market opening in Alberta, power prices have dropped significantly. There is a greater than expected demand side response, increased development in power generation, and a decrease in natural gas prices. Issues that still need to be addressed in Alberta include billing and load settlement issues, invoicing/billing standards, the lack of competition at the retail level, and future balancing of pool charges. Energy Advantage Inc. (EA) does not foresee the same drastic increase in price as seen in Alberta market opening, but suggests that uncertainty and volatility will exist in Ontario. In Alberta, customers who did nothing and stayed on default were the ones who benefited, but took a great risk. EA suggests that customers must understand how and when they use electricity, how much is used during on- and off-peak hours, and in the summer versus the winter. When electricity is priced hourly, it is important to know consumption patterns. 7 figs

    During the five year period 1985 to 1990, Ontario Hydro conducted a major study with the objective to reduce the cost and construction duration for future nuclear generating facilities in Ontario. This paper reports on the study called Major Projects: Schedule and Cost Reduction Study (SCRS). Ontario Hydro is a public utility with the responsibility for meeting electricity need for the province of Ontario with a population of 9.6 million. In order to adequately address future electricity needs, Ontario Hydro has developed and submitted a demand/supply plan which covers the next 25 years. The SCRS for major projects contributed to this demand/supply plan

  4. Towards a sustainable electricity system for Ontario : interim report

    International Nuclear Information System (INIS)

    2004-04-01

    More changes have occurred in Ontario's electricity sector in the past 5 years than over the preceding 9 decades since the creation of Ontario Hydro Electric Power Commission in 1906. The province's nuclear generating facilities were taken out of service in 1997 for safety and maintenance overhauls. The existing nuclear facilities, which account for 28 per cent of the province's generating capacity, will reach the end of their operational lifetimes by 2018. The government of Ontario also announced the phasing out of Ontario Power Generation's coal-fired plants by 2007 due to the environmental health impacts of their operation. These changes have ignited debate over the province's future electricity needs and how they might be met. This study examined by how much electricity demand in Ontario could be reduced through the adoption of energy efficient technologies, fuel switching, cogeneration and demand response measures. It also examined how much future supply could be obtained from renewable energy sources such as wind, the upgrading of existing hydroelectric facilities, and the development of new solar, biomass and small-scale hydro facilities. It also examined how to accommodate the remaining grid demand and which public policies should be adopted to maximize efficiency and other demand side measures. The impacts of the policies were simulated using the Canadian Integrated Modelling System (CIMS) computer model developed by the Energy and Materials Research Group at Simon Fraser University. The CIMS simulations were conducted under the assumptions that barriers to cogeneration would be removed, financial incentives would be provided along with innovative financing programs. The study revealed that capital investments of $18.2 billion over the 2005-2020 period would be required to reduce peak demand of 12,300 MW relative to the business and usual forecast through efficiency, fuel switching and cogeneration. 13 refs., 8 tabs

  7. Creating a competitive electricity market in Ontario - The energy consumer perspective

    International Nuclear Information System (INIS)

    Ford, M.

    1997-01-01

    The large consumers' perspective on the Ontario Government's decision to delay action on restructuring the electric power industry was provided, and recommendations were offered as to the best course of action that the Government ought to take. Ontario Hydro's proposal to restructure itself into separate generation, transmission and retail corporations, and to introduce competition into the Corporation was attacked as unworkable, in that it could not help but encourage price manipulation. The large consumer group also argued that retail distribution in Ontario needs major rationalization without an Ontario Hydro presence. In place of the Ontario Hydro proposal the Association of Major Power Consumers in Ontario (AMPCO) recommends a separate transmission system including an independent system operator, a restructuring of local distribution within a definite time frame and consistent criteria, to be worked out by municipal utilities and Ontario Hydro Retail, and establishment of a Transition Authority independent of Ontario Hydro with a mandate to carry out these changes. While the Ontario Government appears to be unlikely to undertake such a'risky' initiative at this stage of its mandate, significant change, including competition, remains inevitable. It is not a question of whether, but when a fully competitive energy market in Ontario will become a reality. tabs., figs

  10. The safety of Ontario's nuclear power reactors. A scientific and technical review. Ontario Hydro Submission to the Ontario Nuclear Safety Review

    International Nuclear Information System (INIS)

    1987-01-01

    Ontario Hydro is responsible for the safety of its nuclear stations: safety analysis, design and construction, training of operators, operating practices, and maintenance procedures. The utility must demonstrate to the regulatory body and the public that it is capable of operating nuclear stations safely. the dedicated attention of management and workers alike has been given to the achievement of an excellent safety record. Safety begins with well understood corporate goals, objectives and policies, and the clear assignment of responsibilities to well-trained, competent people who have the relevant experience and the right information and equipment. A prime cause of both the Chernobyl and the Three Mile Island accidents was a breakdown in operational procedures and human factors. On the contrary, the pressure tube failure at Pickering unit 2 in 1983 was understood almost immediately by the operators, who took the correct steps to shut down the reactor. This success is related to well-designed control room information systems and good understanding of fundamentals by the operators. Increasingly, in the design of nuclear plant control and instrumentation systems and in training in Ontario Hydro, the well-being, capabilities and limitations of humans are being taken into account. This report describes the series of barriers between the radioactive material in the fuel and the series of barriers between the radioactive material in the fuel and the environment, and the stringent quality control and technical measures taken to make the likelihood of malfunctions very small. Defence in depth protection for the public is a feature of all Ontario Hydro nuclear stations. As safety-related systems are updated in new stations, improvements are in some cases being backfitted to older stations

    Cruess, Gordon

    2003-12-01

    On 7 October 2003, the Ontario Court of Appeal upheld the Ontario Superior Court of Justice decision in Hitzig, which found that the Marihuana Medical Access Regulations (MMAR) represented an unconstitutional barrier to accessing a legal supply of marijuana for persons with a recognized medical need. The Court of Appeal tailored its remedial order by striking down the second specialist test required for certain applicants, and eliminating the unconstitutional eligibility and supply provisions, rather than declaring unconstitutional the entire MMAR as the lower court had done. The court's declaration was made effective immediately, in order to maintain the prohibition for non-medicinal possession of marijuana under section 4 of the Controlled Drugs and Substances Act (CDSA), and to constitutionalize the medical exemption for marijuana possession created under the MMAR.

  12. New avenues in cobalt-60 production at Ontario Hydro

    International Nuclear Information System (INIS)

    Mylvaganam, C.K.; Ronchka, R.A.

    1990-01-01

    Ontario Hydro produces cobalt-60 in the control rods of twelve power reactors. These reactors have a typical flux of 2 x 10 14 neutrons/cm 2 /s, making them efficient producers of cobalt-60. Current annual production is 45 million curies. Since the primary function of these reactors is the production of electricity, their flexibility to meet the needs of commercial cobalt production by the control rod route is limited. Ontario Hydro is therefore developing innovative production techniques, making use of the CANDU reactor's unique ability to be fuelled on-power. These techniques will enable production to better respond to the market's requirements for quantity and specific activity. As it is supplementary to control rod production, annual supply could potentially reach 165 million curies. (author)

    Little is known about job satisfaction among Canada's social work workforce in aging, although social workers remain a key component of interdisciplinary care in health and social service settings. This study begins to address this gap in knowledge by examining individual, interpersonal, and job-design factors influencing the job satisfaction of gerontological social workers in Ontario. Data were collected via two online surveys with a sample drawn from the Ontario Association of Social Workers' membership list (N = 104). A multiple regression model explained 37% of the variance in job satisfaction, F = 5.47[10, 93], p job satisfaction, advancing promotional opportunities for social work clinicians, and providing educational and clinical supports to clinicians.

  14. Deregulation and the Alberta experience : the implications for Ontario

    2002-01-01

    This paper provides a 15 month assessment of Alberta's new competitive electricity market. It also presents lessons that Ontario customers could learn from Alberta's experience. The goal for restructuring is to achieve lower electricity prices, competitive retail markets, increased flexibility of contracts, and to remove investment risks from consumers. Alberta's restructured market includes power generation, high voltage transmission, low voltage transmission and retail sales. Economists agree that deregulation has brought lower prices and other consumer benefits despite some imperfections. After one year, prices in Alberta have gone down from $130/MWh to $30/MWh. Power supply has increased along with demand response, market competitiveness, liquidity, and thermal and economic efficiency. In 2001, Alberta was a net exporter of electricity. In 2001, it was ranked by the Center for Advancement of Energy Markets (CAEM) which ranks states and provinces by 22 attributes for how they are restructuring their power markets. Alberta ranked first overall in North America. Ontario ranked sixteenth. 4 tabs., 5 figs

  15. Comparison of Ontario Hydro's performance with world power reactors - 1981

    1982-04-01

    The performance of Ontario Hydro's CANDU reactors in 1981 is compared with that of 123 world nuclear power reactors rated at 500 MW(e) or greater. The report is based on data extracted from publications, as well as correspondence with a number of utilities. The basis used is the gross capacity factor, which is defined as gross unit generation divided by the perfect gross output for the period of interest. The lowest of the published turbine and generator design ratings is used to determine the perfect gross output, unless the unit has been proven capable of consistently exceeding this value. The first six reactors in the rankings were CANDU reactors operated by Ontario Hydro

    This article overviews the second phase of a two-phase study which examined experiences of health and social exclusion among mothers experiencing homelessness in Ontario, Canada. A critical discourse analysis was employed to analyze the policy document, Realizing Our Potential: Ontario's Poverty Reduction Strategy, 2014-2019. In nursing, analysis of policy is an emerging form of scholarship, one that draws attention to the macro levels influencing health and health promotion, such as the social determinants of health, and the policies that impact them. The clear neo-liberal underpinnings, within the strategy, with a focus on productivity and labor market participation leave little room for an understanding of poverty reduction from a human rights perspective. Further, gender-neutrality rendered the poverty experienced by women, and mothers, invisible. Notably, there were a lack of deadlines, target dates, and thorough action and evaluation plans. Such absence troubles whether poverty reduction is truly a priority for the government, and society as a whole.

    The implementation of a program for the naturalization of Nanticoke Park, a 30 hectare area located on the property of Ontario Hydro's Nanticoke Generating Station was discussed. The station, which is located in southern Ontario very near to noted wildlife areas, is the largest coal-fired generating station in North America. Naturalization of Nanticoke Park began with passive naturalization of interior areas. An active naturalization program involving four to five hectare size areas annually was begun in 1997, to be completed over a five -year period. This presentation described the site preparation, planting methods, post-planting tending methods, survival assessment of planted areas, and scientific research initiatives including mulch trials with zebra mussel shells to increase soil moisture. The lessons learned from the two year experiment in determining the optimum planting strategy and methods were described. 7 refs., 1 tab

    Problems that can arise when Western oil companies invest in developing countries suffering under political instability are described using Calgary-based Talisman Energy Inc.'s recent experiences in the Sudan as example. In 1998 Talisman acquired a 25 per cent interest in an oil project by cash-poor Arakis Energy Corporation, thus acquiring a foothold in the Middle East , and more importantly, access to one of the world's largest oil reserves at a bargain-basement price. A UN report accusing the Sudanese government of gross human rights violations , the chagrin expressed by the US Secretary of State that a Canadian company would do business with a country that the US officially regards as 'a state sponsor of terrorism', a warning by the Canadian Minister of Foreign Affairs of economic sanctions unless Talisman demonstrates active promotion of human rights in the Sudan, led the Ontario Teachers Federation to threaten to withdraw its $ 184-million stake in Talisman if reports of human rights abuses in the country can be corroborated. A fact finding mission has been dispatched by the Minister of Foreign Affairs to establish by next month who is killing whom in the Sudan and whether oil revenue from Talisman is being used to fund a campaign of terror and killing that have claimed the lives of some two million Sudanese citizens in the past 16 years. As a result of the turmoil caused by these actions Talisman lost nearly $ 700 million in value in the last week of October, and several institutional investors are actively considering selling their shares in Talisman. The company has hired a top public relations firm to defend itself against the 'coordinated attack' by human rights groups, Sudanese refugees, and Christian fundamentalists whose aim is said to be to shut down oil production in the Sudan. Talisman management is confident that given the company's reputation and its large asset base, it can weather the storm that its Sudanese assets have generated, however

    The goal of this research was to understand factors that affect future practice intentions of physicians who practise in rural and underserviced areas. The following 2 research questions are answered: "How many physicians in Northwestern Ontario intend to leave their practice in 5 years?" and "What is the association between professional, personal/family and community factors in physician satisfaction and intention to stay in practice?" Between September and October 2004, physicians practising in Northwestern Ontario were mailed a survey measuring professional, personal/family and community satisfaction as well as future practice intentions. Future practice intention (question 1) was analyzed through a frequency distribution, while the factors that influenced intention (question 2) were analyzed using a 3-step process: a factor analysis, the creation of scales and a logistic regression. The themes of the scales emerging from the factor analysis were family/community, time, professional support and efficacy, and sense of belonging and appreciation. The means of these 4 scales were entered into a logistic regression model along with demographic variables that were independent predictors of future practice intention. Three hundred and twenty-eight physicians were sent the survey. After 3 consecutive mailings, the response rate was 61.3% (n=201). Over two-thirds of Northwestern Ontario physicians intended to remain in practice in 5 years; however, most of these physicians were from Thunder Bay, the only city (100 000+ population) in Northwestern Ontario. Physicians were significantly more likely to intend to stay in practice if they were younger, practised in Thunder Bay and scored higher on the family/community scale. These findings underscore the importance of addressing family and community factors, as opposed to strictly professional factors, in future retention initiatives.

  20. Adaptation to climate change in the Ontario public health sector

    Full Text Available Abstract Background Climate change is among the major challenges for health this century, and adaptation to manage adverse health outcomes will be unavoidable. The risks in Ontario – Canada’s most populous province – include increasing temperatures, more frequent and intense extreme weather events, and alterations to precipitation regimes. Socio-economic-demographic patterns could magnify the implications climate change has for Ontario, including the presence of rapidly growing vulnerable populations, exacerbation of warming trends by heat-islands in large urban areas, and connectedness to global transportation networks. This study examines climate change adaptation in the public health sector in Ontario using information from interviews with government officials. Methods Fifty-three semi-structured interviews were conducted, four with provincial and federal health officials and 49 with actors in public health and health relevant sectors at the municipal level. We identify adaptation efforts, barriers and opportunities for current and future intervention. Results Results indicate recognition that climate change will affect the health of Ontarians. Health officials are concerned about how a changing climate could exacerbate existing health issues or create new health burdens, specifically extreme heat (71%, severe weather (68% and poor air-quality (57%. Adaptation is currently taking the form of mainstreaming climate change into existing public health programs. While adaptive progress has relied on local leadership, federal support, political will, and inter-agency efforts, a lack of resources constrains the sustainability of long-term adaptation programs and the acquisition of data necessary to support effective policies. Conclusions This study provides a snapshot of climate change adaptation and needs in the public health sector in Ontario. Public health departments will need to capitalize on opportunities to integrate climate change into

    "Road rage" has increasingly generated public concern, however, the prevalence of this behaviour has not been available. We examine the prevalence and demographic correlates of road rage victimization and perpetration based on a population survey of adults in Ontario. Data are based on the CAMH Monitor, a repeated cross-sectional telephone survey of Ontario adults (n = 1,395). The contribution of demographic factors to road rage was examined with logistic regression analysis. About half of respondents (46.6%) were shouted at, cursed at or had rude gestures directed at them in the past year, and 7.2% were threatened with damage to their vehicle or personal injury. Nearly a third of respondents (31.7%) admitted to shouting, cursing, etc. at someone, and 2.1% threatened to hurt someone or damage their vehicle. Being a Toronto resident, being younger, and earning a higher income were associated with greater likelihood of being a victim of shouting, cursing and rude gestures; however, income was not associated with being threatened with vehicle damage or injury. The likelihood of admitting to shouting, etc. at someone was greater for males, younger respondents, Toronto residents, higher income earners, and never married respondents; however, threatening someone was associated with younger age and lower education level. These results provide a first indication of the prevalence of road rage in Ontario. Road rage, in its milder forms, appears to be common, involving between a third and a half of respondents as either a victim or a perpetrator. Nearly 1 in 10 Ontario residents were threatened with damage or personal injury.

    Gaboury, J.

    2001-01-01

    The focus of this presentation was on the generation and sale of electricity. Prior to deregulation, companies that generated electricity had a readily available customer base to whom the electricity could be sold. The author discussed some of the changes affecting the industry as a result of deregulation of the electricity market in Ontario: the increasing number of companies, as well as the increased number of generators supplying power within the province. Currently 85 per cent of the generation in Ontario is met by Ontario Power Generation (OPG) and this percentage will decrease through de-control. De-control can be achieved in a variety of ways, either through the sale of assets, leases, asset swaps. The market rules dictate that OPG not control in excess of 35 per cent of the generation supply in Ontario, OPG is examining the situation. New supply being constructed or new interconnections with neighboring markets could affect the total assets that would have to be de-controlled. OPG has a mix of generation that includes hydroelectric, fossil, and nuclear, as well as a single wind turbine. Green power, defined as electricity generation deemed less intrusive environmentally than most traditional generation, includes wind, water, landfill gas, solar and others, and could affect the mix of generation. It is expected that there will be a niche market for green power, especially when one considers the reduction in emissions. It could represent a viable option for smaller startup companies, as less capital is required. The options for selling the power, either to the spot market or by entering into a bilateral contract with another customer, were explained

    1989-03-01

    This report summarizes the preliminary results of geological and geophysical investigations of possible neotectonic features in Prince Edward County, southern Ontario, made by the Ontario Geological Survey during 1988. Low magnitude seismic events indicative of contemporary stress relief occurred during 1987-88 near Salmon Point and Consecon (M 2.2). These events were located proximal to a major regional fault system crossing Lake Ontario and consisting of the Clarendon-Linden Fault System in New York State and the Salmon River-Picton fault systems in Ontario. Detailed observations were made of regional jointing orientations (predominantly 60 degrees and 125 degrees), erosion of surficial deposits adjacent to open fractures, a local fault displacement (post-glacially), dome structures located at Point Petre, and dissolution/karst terrains in the eastern part of the study area. Excavations of four pop-up structures indicate that three are classical pop-ups and one is atypical in structure. Level transects were conducted across complex structures in the eastern part of the study area. Detailed refraction seismic and resistivity surveys were conducted on pop-up and fault features. Preliminary results indicate that the Picton Fault is a complex zone of fractures with differing bedrock on each side. The central zone of the East Duck Pond pop-up is fractured and may contain variable amounts of water. Overturned and upright folds in the Consecon Quarry located outside of the primary research area were documented and found to be trending in a west-northwest to northwest direction. This fold orientation is compatible both with a glacial shove origin and with the present stress field orientations. Although glacial shove can produce overturned folds, it cannot form upright folds. A regional, tectonic deformation oriented northeasterly is therefore suggested as the causative mechanism

    Relatively few longitudinal studies have explored the relationship between psychosocial work conditions and diabetes incidence. Given the increasing global burden of diabetes this is an important area for public health research. To examine the relationships between dimensions of the psychosocial work environment on the subsequent incidence of diabetes among men and women in Ontario, Canada over a 9 year period. We used data from Ontario respondents (35 to 60 years of age) to the 2000-01 Canadian Community Health Survey linked to the Ontario Health Insurance Plan database for physician services and the Canadian Institute for Health Information Discharge Abstract Database for hospital admissions. Our sample of actively employed labour market participants with no previous diagnoses for diabetes was followed for a 9 year period to ascertain incident diabetes. There were 7443 participants. Low levels of job control were associated with an increased risk of diabetes among women, but not among men. Counter to our hypotheses high levels of social support were also associated with increased diabetes risk among women, but not among men. No relationship was found between any psychosocial work measure and risk of diabetes among men. Given the increasing prevalence of diabetes worldwide, job control could potentially be an import ant modifiable risk factor to reduce the incidence of diabetes among female, but not among male, workers. More research is needed to understand the pathways through which low social support may protect against the development of diabetes.

    To understand the factors that affect the distribution of physiotherapists in Ontario by examining three potential influences in the multi-payer physiotherapy (PT) market: population need, critical mass (related to academic health science centres [AHSCs]), and market forces. Physiotherapist density and distribution were calculated from 2003 and 2005 College of Physiotherapists of Ontario registration data. Physiotherapists' workplaces were classified as not-for-profit (NFP) hospitals, other NFP, or for-profit (FP), and their locations were classified by census division (CD) types (cities and counties). Physiotherapist density varied significantly and distribution was neither uniformly responsive to population need, nor driven primarily by market forces. The largest factor was an AHSC in a CD; physiotherapists locate disproportionately in NFP hospitals in AHSCs rather than in the growing FP sector. While some patterns can be discerned in the distribution and densities of physiotherapists across Ontario, further work needs to be done to identify why population need and market forces appear to be less influential, and why CDs with AHSCs are so attractive to physiotherapists. With this additional information, it may be possible to identify ways to influence uneven distribution in the future.

    On June 28, 2001, the Ontario Legislative Assembly appointed the Select Committee an Alternative Fuel Sources, comprised of representatives of all parties, with a broad mandate to investigate, report and offer recommendations with regard to the various options to support the development and application of environmentally sustainable alternatives to the fossil fuel sources already existing. The members of the Committee elected to conduct extensive public hearings, conduct site visits, attend relevant conferences, do some background research to examine a vast number of alternative fuel and energy sources that could be of relevance to the province of Ontario. A discussion paper (interim report) was issued by the Committee in November 2001, and the present document represents the final report, containing 141 recommendations touching 20 topics. The information contained in the report is expected to assist in the development and outline of policy and programs designed to specifically support alternative fuels and energy sources and applicable technologies. Policy issues were discussed in Part A of the report, along with the appropriate recommendations. The recommendations on specific alternative fuels and energy sources were included in Part B of the report. It is believed that the dependence of Ontario on traditional petroleum-based fuels and energy sources can be reduced through aggressive action on alternative fuels and energy. The benefits of such action would be felt in the area of air quality, with social, and economic benefits as well. 3 tabs

    The purpose of the workshop was to review available geological and seismological data which could affect earthquake occurrence in southern Ontario and to develop a consensus on approaches that should be adopted for characterization of seismic hazard. The workshop was structured in technical sessions to focus presentations and discussions on four technical issues relevant to seismic hazard in southern Ontario, as follows: (1) The importance of geological and geophysical observations for the determination of seismic sources, (2) Methods and approaches which may be adopted for determining seismic sources based on integrated interpretations of geological and seismological information, (3) Methods and data which should be used for characterizing the seismicity parameters of seismic sources, and (4) Methods for assessment of vibratory ground motion hazard. The format of each session involved invited presentations of relevant data followed by open presentations by participants, a general discussion focusing on the relevance of the presented information for seismic hazard assessment in southern Ontario, then development of conclusions and recommendations. In the final session, the conclusions and recommendations were summarized and an open discussion was held to develop consensus. This report presents perspective summaries of the workshop technical sessions together with conclusions and recommendations prepared by the session chairs and the general chairman. 2 refs

    Kelly, B. [EcoPathways Consulting Inc., Whitby, ON (Canada)

    1997-12-31

    A review of Ontario Hydro`s green power program was provided. Market research indicates that the public is interested in renewable energy, that a significant portion of the public claim to be `green` consumers, and that they are willing to pay a premium for green power. There is, however, very little actual experiential evidence to show who is truly willing to pay and what price would be acceptable. Sources of `green electricity` include renewables such as hydro, solar, wind, biomass from farm and forest waste, methane from landfills, and geothermal. Public support in Ontario, and in most other parts of Canada, is strong for investment by power utilities in `green electricity`. In a limited program, Ontario Hydro is currently offering greenpower pricing for some of its proposed green power projects. To those willing to pay, a premium of 4 cents per kWh will be added to the current costs from the electricity retailer. The general impression of industry experts is that the demand for green power is there, however, the supply is not. Continued delays and uncertainty about the power industry`s future structure are considered to be the major impediments to implementing the green program. 1 tab., 7 figs.

  12. Ontario electricity outlook : smaller reserve margins and higher prices

    International Nuclear Information System (INIS)

    2002-01-01

    Privatization of Hydro One has been delayed, but this will not postpone the scheduled launch of restructuring the electricity markets in Ontario on May 1, 2002. The main concern of Ontario consumers is whether they will undergo an energy crisis such as the one experienced in California. A report released in February 2002 stated that electricity bills will be higher under the new electricity regime. It appears that electricity supply reserve margins will be tighter than originally thought, raising price volatility in the summer and fall. The authors claim that the chance for an energy crisis are low because of the added generating capacity. However, regardless of whether consumers sign a fixed term price contract with retailers, it is likely that electricity bills will be higher in 2002 and 2003. The Independent Electricity Market Operator (IMO) is assuring the public that the power generation resources currently available are sufficient to meet expected demand. However, in June through July, it is possible that reserves will fall short. It is also evident that charges for distribution, transmission and other services will be higher under the restructured system. Electricity bills are likely to be about 5 to 15 per cent higher in 2003 than they were before March 1, 2002. Higher prices might not last indefinitely. Initially, they will be used to pay off the debt, but competition and opportunities for profit should allow for greater efficiencies and innovation in Ontario's electricity system and prices could potentially fall lower than pre-deregulation prices. 1 tab., 3 figs

    1998-01-01

    The principles and concepts behind the development of the new business plan of the Ontario Ministry of Natural Resources, as it relates to the petroleum/salt industries in the province are described. The business planning approach adopted by the Progressive Government of the Province, is expected to provide the framework within which to examine alternate service delivery mechanisms in an environment of reducing budgets and staff. It is expected to implement a new business approach with client industries which focuses on innovative concepts of alternative service delivery and government/industry partnership. The foundation of this new approach is Bill 52, proclaimed in June 1997, which created new legislation, called the 'Oil, Gas and Salt Resources Act' which facilitated implementation of the new business approach. According to the business plan, the provincial focus will be confined to the development of new policies and standards, provision of technical approvals, assurance of compliance and maintenance of a technical and administrative database. It is expected that the new government/industry partnership will result in greater self-reliance, co-operative accountability and responsibility by industry, and a stronger and more vibrant industry sector. 1 ref

    This paper reported on a study which generated experimental data for validating weathering algorithms and computerized oil weathering models in the presence of ice and snow. Over a 4-year period, 6 laboratory-scale experiments were conducted at 3 facilities, notably an outdoor test facility near Ottawa, Ontario; an indoor wind/wave tank in Ottawa; and the Ohmsett Facility in New Jersey. The goals of the experiments were to study the fate of 4 Alaskan crude oils in terms of spreading on ice and in snow; evaporation in ice and snow; slick thickness on cold water; migration rates through brine channels; formation of water-in-oil emulsions; and full spill-related characterization of crude oil samples. The fate, behaviour and interactions of fresh crude oil spilled with first-year, land-fast sea ice were investigated using extensive laboratory testing with meso-scale verification. It was not possible to develop algorithms for emulsification process in drift or ice, or for the rate of appearance of oil on the surface of melting ice in spring. The study showed that oils whose pour point exceeds ambient temperature have unusual physical characteristics. As these oils cool, wax particles begin to precipitate from solution in the bulk oil and eventually form a polymer-like matrix in the oil that renders it a gel-like semi-solid. The oil therefore develops a resistance to flow. These changes significantly reduce the spreading of oil on water, on ice and through snow. The onset of the internal wax matrix also restricts diffusive movement of the volatile molecules through the slick to the air/oil surface that changes the way in which the oil evaporates. The reduced evaporation can be modelled using an internal resistance to mass transfer. 13 refs., 14 tabs., 18 figs

We analyzed a database of all patient clinic visits, laboratory tests for urine toxicology screening, and methadone scripts from a group of methadone clinics in Ontario. The database consisted of patient visits and visit information from 1 January 2003 to 31 December 2009. We estimated the cost of providing methadone maintenance treatment as the sum of physician costs, laboratory costs for urine samples (toxicology screens), methadone costs, and pharmacy costs. Pharmacy costs include dispensing fees and markups. All costs are expressed in 2010 Canadian dollars. The database consisted of 9479 unique patients. The average age on the date of the first recorded visit was 34.3, and among the patients 62.3% were male. There were 6,425,937 patient days of treatment and the total cost of all treatment-related services was approximately $99,491,000. The total cost was comprised of physician billing (9.8%), pharmacy costs (39.8%), methadone (3.8%), and performing urine toxicology screens (46.7%). The average cost per day for treatment was $15.48, corresponding to $5651per year if patients were to remain in treatment continuously. The cost of providing methadone maintenance treatment in Ontario is comparable to estimates from the United States and Australia. This information is important to policy makers for planning and budgeting purposes and as part of a full cost-benefit or cost-effectiveness analysis of methadone treatment.

    The purpose of this study is to analyze the relationship between newly introduced primary care models in Ontario, Canada, and patients' primary care and total health care costs. A specific focus is on the payment mechanisms for primary care physicians, i.e. fee-for-service (FFS), enhanced-FFS, and blended capitation, and whether providers practiced as part of a multidisciplinary team. Utilization data for a one year period was measured using administrative databases for a 10% sample selected at random from the Ontario adult population. Primary care and total health care costs were calculated at the individual level and included costs from physician services, hospital visits and admissions, long term care, drugs, home care, lab tests, and visits to non-medical health care providers. Generalized linear model regressions were conducted to assess the differences in costs between primary care models. Patients not enrolled with a primary care physicians were younger, more likely to be males and of lower socio-economic status. Patients in blended capitation models were healthier and wealthier than FFS and enhanced-FFS patients. Primary care and total health care costs were significantly different across Ontario primary care models. Using the traditional FFS as the reference, we found that patients in the enhanced-FFS models had the lowest total health care costs, and also the lowest primary care costs. Patients in the blended capitation models had higher primary care costs but lower total health care costs. Patients that were in multidisciplinary teams (FHT), where physicians are also paid on a blended capitation basis, had higher total health care costs than non-FHT patients but still lower than the FFS reference group. Primary care and total health care costs increased with patients' age, morbidity, and lower income quintile across all primary care payment types. The new primary care models were associated with lower total health care costs for patients compared to the

    Mainhood, Lindsay Ann

    In nearly all countries of the world, at every level of education, physics as a field of science is failing to recruit and retain women. This phenomenon is believed to relate to girls' educational experiences from K-12, but the reasons for the gender gap in physics are not fully understood. The purpose of this phenomenological research is to explore and understand the barriers encountered by Ontario female high school students during their physics education and the meanings attributed to those barriers by these young women. This research is guided by social cognitive career theory (SCCT) and uses the concept of physics identity as a lens through which the influence of contextual barriers can be understood. Nine participants, selected via snowball sampling from an Eastern Ontario university, together participated in four semi-structured focus group meetings and individually participated in a single in-depth, one-on-one interview. Audio data was transcribed verbatim and analyzed using a general inductive approach. Emergent themes are descriptively presented as the findings of the research study: perceiving the high school physics experience, experiencing high school physics education, and identity and gender in the high school physics experience. Sub-themes presented include limited prior experiences, negative perceptions of physics, images of physics learners, decision-making, reactions to pedagogy, learning needs, physics identity, gender-dependent influences, and making meaning of the experiences in high school physics. The shared experience of high school physics education for young women is understood as both a richly challenging and rewarding experience. Based on the findings of this research, recommendations are made for practical and research settings, and for future work in this area. Drawing on literature on underrepresentation of women in physics, this research contributes to the physics education research community and beyond; it offers voices of Ontario

    2014-08-01

    Accreditation in Ontario, Canada, requires that licensed clinical laboratories participate in external quality assessment (also known as proficiency testing) and perform competency evaluation of their staff. To assess the extent of ongoing competency assessment practices, the Quality Management Program--Laboratory Services (QMP-LS) Microbiology Committee surveyed all 112 licensed Ontario microbiology laboratories. The questionnaire consisted of a total of 21 questions that included yes/no, multiple-choice, and short-answer formats. Participants were asked to provide information about existing programs, the frequency of testing, what areas are evaluated, and how results are communicated to the staff. Of the 111 responding laboratories, 6 indicated they did not have a formal evaluation program since they perform only limited bacteriology testing. Of the remaining 105 respondents, 87% perform evaluations at least annually or every 2 years, and 61% include any test or task performed, whereas 16% and 10% focus only on problem areas and high-volume complex tasks, respectively. The most common methods of evaluation were review of external quality assessment (EQA) challenges, direct observation, and worksheet review. With the exception of one participant, all communicate results to staff, and most take remedial action to correct the deficiencies. Although most accredited laboratories have a program to assess the ongoing competency of their staff, the methods used are not standardized or consistently applied, indicating that there is room for improvement. The survey successfully highlighted potential areas for improvement and allowed the QMP-LS Microbiology Committee to provide guidance to Ontario laboratories for establishing or improving existing microbiology-specific competency assessment programs.

    Emergency Preparedness Plans (EPPs) are essential during dam emergencies or failures; the absence of legislation about dam safety does not exempt dam owners of legal liabilities and responsibilities for dam safety. Ontario Hydro instituted a dam safety EPP program in 1992. An overview of the Plan, and its recent integration with overall site emergency planning was described, with case studies to illustrate development, implementation, testing and training processes. A recent development was the network version of the EPP, which not only streamlined maintenance of the Plan, but also increased its effectiveness by providing instant access to the most up-to-date version of the Plan. 6 refs., 5 figs

    The risk of colorectal cancer (CRC) varies around the world and between females and males. We aimed to compare the risk of CRC among immigrants to Ontario, Canada, to its general population. We used an exposure-control matched design. We identified persons in the Immigration, Refugees and Citizenship Canada Permanent Resident Database with first eligibility for the Ontario Health Insurance Plan between July 1, 1991 and June 30, 2008 at age 40 years or older, and matched five controls by year of birth and sex on the immigrant's first eligibility date. We identified CRC from the Ontario Cancer Registry between the index date and December 31, 2014. All analyses were stratified by sex. We calculated crude and relative rates of CRC. We estimated risk of CRC over time by the Kaplan-Meier method and compared immigrants to controls in age and sex stratified strata using log-rank tests. We modeled the hazard of CRC using Cox proportional hazards regression, accounting for within-cluster correlation by a robust sandwich variance estimation approach, and assessed an interaction with time since eligibility. Among females, 1877 cases of CRC were observed among 209,843 immigrants, and 16,517 cases among 1,049,215 controls; the crude relative rate among female immigrants was 0.623. Among males, 1956 cases of CRC were observed among 191,792 immigrants and 18,329 cases among 958,960 controls; the crude relative rate among male immigrants was 0.582.. Comparing immigrants to controls in all age and sex stratified strata, the log rank test p  = 75 years at index, where p = 0.01. The age-adjusted hazard ratio (HR) for CRC among female immigrants was 0.63 (95% CI 0.59, 0.67) during the first 10 years, and 0.66 (95% CI 0.59, 0.74) thereafter. Among male immigrants the age-adjusted HR = 0.55 (95% CI 0.52, 0.59) during the first 10 years and increased to 0.63 (95% CI 0.57, 0.71) thereafter. The adjusted HR > = 1 only among immigrants born in Europe and Central Asia. The risk

    The author's aim was to give very precise information on the many causes and effects of the oil crises that have occurred since 1900, and at the same time offer the reader the possibility to build up a basic knowledge of the oil industry and market, as he feels that the public is often subjected to misleading information. Political and economical aspects are elaborated. First-hand sources such as statistics and investigations have been used as far as possible to give information on the oil market. An oil crisis is defined by the author as a significant change in the price of oil compared to prices of other goods. Changes can be in the form of either rising or falling prices. A special chapter concentrates on Denmark in relation to the oil crises. (AB) (165 refs.)

    Wetmiller, R.J.; Cajka, M.G.

    1989-01-01

    The northern Ontario seismograph network, which has operated under the Canadian Nuclear Fuel Waste Management Program since 1982, has provided valuable data to supplement those recorded by the Canadian national networks on earthquake activity, rockburst activity, the distribution of regional seismic velocities, and the contemporary stress field in northern Ontario. The combined networks recorded the largest earthquake known in northwestern Ontario, M 3.9 near Sioux Lookout on February 11, 1984, and many smaller earthquakes in northeastern Ontario. Focal mechanism solutions of these and older events showed high horizontal stress and thrust faulting to be dominant features of the contemporary tectonics of northern Ontario. The zone of more intense earthquake activity in western Quebec appeared to extend northwestward into the Kapuskasing area of northeastern Ontario, where an area of persistent microearthquake activity had been identified by a seismograph station near Kapuskasing. Controlled explosions of the 1984 Kapuskasing Uplift seismic profile experiment recorded on the northern Ontario seismograph network showed the presence of anomalously high LG velocities in northeastern Ontario (3.65 km/s) that when properly taken into account reduced the mislocation errors of well-recorded seismic events by 50% on average

  4. Energy utility reform in eastern Canada: electric monopolies still in the dark ages. Can Ontario`s gas reforms light the way?

    Energy Technology Data Exchange (ETDEWEB)

    Adams, T. [Energy Probe, Toronto, ON (Canada)

    1997-08-01

    The electric and gas utility reform in eastern Canada jurisdictions, specifically in New Brunswick, Quebec and Ontario were reviewed. Progress towards a more competition-oriented operation was the principal theme. With regard to New Brunswick, the financial and operational crisis of NB Power, the provincially owned utility, was described. It was argued that in keeping with the trend towards privatization it would be preferable to privatize NB Power rather than allowing it to become an even larger monopoly by taking control of Sable Island gas distribution. In Quebec, two government-owned utilities, Hydro-Quebec and Gaz Metropolitain, were consolidated to strengthen the government`s monopoly. In view of the lack of competition and unequal access to meet the criteria of the Federal Energy Regulatory Commission (FERC), Hydro-Quebec`s main challenge is to retain access to the US market. The US FERC order is a major barrier to Hydro-Quebec. In the Ontario portion of the review, the financial crisis facing Ontario Hydro received extensive coverage. Ontario Hydro was accused of protecting its monopolistic power to control provincial power users, and to prevent independent producers to do business in the province. By contrast, in the Ontario natural gas sector competition is growing, led by initiatives of the Ontario Energy Board and supported by all major gas utilities. Energy Probe is advocating an Independent System Operator (ISO) for the gas system, a concept universally accepted as necessary in competition-oriented integrated electric power systems.

  5. Tobacco Retail Outlets and Vulnerable Populations in Ontario, Canada

    Directory of Open Access Journals (Sweden)

    Michael O. Chaiton

    2013-12-01

    Full Text Available Interest has been increasing in regulating the location and number of tobacco vendors as part of a comprehensive tobacco control program. The objective of this paper is to examine the distribution of tobacco outlets in a large jurisdiction, to assess: (1 whether tobacco outlets are more likely to be located in vulnerable areas; and (2 what proportion of tobacco outlets are located close to schools. Retail locations across the Province of Ontario from Ministry of Health Promotion data were linked to 2006 Census data at the neighbourhood level. There was one tobacco retail outlet for every 1,000 people over age 15 in Ontario. Density of outlets varied by public health unit, and was associated with the number of smokers. Tobacco outlets were more likely to be located in areas that had high neighbourhood deprivation, in both rural and urban areas. Outlets were less likely to be located in areas with high immigrant populations in urban areas, with the reverse being true for rural areas. Overall, 65% of tobacco retailers were located within 500 m of a school. The sale of tobacco products is ubiquitous, however, neighbourhoods with lower socio-economic status are more likely to have easier availability of tobacco products and most retailers are located within walking distance of a school. The results suggest the importance of policies to regulate the location of tobacco retail outlets.

  6. Deregulation and the Alberta experience : the implications for Ontario

    International Nuclear Information System (INIS)

    Spearman, C.

    2002-01-01

    The government of Alberta deregulated its electric power industry to introduce industry structure and regulatory reforms that would promote competitive electricity prices. The objective was to ensure fairness for customers and generating facilities. A graph depicting power pool prices shows the reality of soaring prices at the onset of deregulation in Alberta. Today, there remains uncertainty in the development of retail choice, additional rate riders, new generation, transmission expansion, other jurisdictions and future prices. Consumers are still poorly equipped to make decisions and farmers have no means of protection from fluctuating electricity prices. They see deregulation as a complete failure because costs are up and benefits are nowhere to be seen. Ontario can learn from the Alberta experience by adopting the recommendations to set financial penalties for incompetence, financial compensation to customers for errors, and to be fully ready with systems tested ahead of deregulation. Anticipated customer benefits should be clearly identified in advance. The future electric power industry in Ontario needs vision, stability, a cohesive plan, and leadership devoid of complacency. 1 fig

  7. Regulating Traditional Chinese Medicine Practitioners and Acupuncturists in Ontario, Canada

    Directory of Open Access Journals (Sweden)

    Glen E. Randall

    2015-12-01

    Full Text Available In 2006, the Ontario government passed the Traditional Chinese Medicine Act, which granted Traditional Chinese Medicine practitioners and Acupuncturists (TCM/A practitioners self-regulatory status under the Regulated Health Professions Act, 1991. The goal of the legislation was to create a new regulatory college that would set and enforce high standards of care and safety in order to enhance public protection and access to a range of traditional and alternative therapies. In April 2013, the College of Traditional Chinese Medicine Practitioners and Acupuncturists of Ontario was officially launched. Several factors account for the government’s decision to delegate self-regulatory authority to TCM/A practitioners through the creation of a regulatory college. In particular, the government’s decision seems to have been influenced by lobbying of some practitioners, greater public acceptance of alternative medicines, patient safety concerns related to acupuncture cases in the media, and the precedence of self-regulatory status being granted to these practitioners in other provinces. The degree to which the legislation has achieved its goals is difficult to determine given the short period of time the regulatory college has existed. However, the fact that the college has developed standards of practice to guide TCM/A practitioners and has a process in place to address public complaints is an early indication of movement toward achieving the policy’s goals.

  8. Electricity transmission and distribution in Ontario : a look ahead

    International Nuclear Information System (INIS)

    2004-01-01

    This paper addressed changes and challenges that can guide the Ontario government in developing a policy framework for sustainable development in the electric power industry, particularly the power distribution and transmission sector. The government is taking action to adopt a balanced approach to energy policy that combines features of both regulated and competitive industries. It is taking a more responsible approach to electricity pricing that ends subsidies in order to reflect the true cost of electricity. The major issues facing the wires sector are: improving efficiencies by consolidating activities, streamlining operations and unbundling power transmission and distribution into separate entities; developing distributed generation; and, investing in new transmission to relieve congestion. It was noted that distributed generation will become more important as coal-fired generation facilities are replaced. Distributed generation offers many benefits for the wires sector, including delaying the need to upgrade the existing wires network, offering local solutions to transmission constraints, reducing system losses, improving load factor and improving the reliability of supply. An increase in distributed generation will likely mean that more of Ontario's electricity supply will come from small-scale renewable generation facilities. The government promotes private sector investment to assist in the rebuilding of the electricity sector

  9. Legislation governing tobacco use in Ontario's retirement homes.

    2018-01-01

    Legislation banning smoking in public places is a key component of comprehensive tobacco control programs, yet residential facilities for aging adults are often exempt from such legislation. In Ontario, Canada, provincial legislation does not comprehensively safeguard retirement homes' residents and staff from tobacco-related health and safety concerns. This study provides a descriptive analysis of municipal-level bylaws in order to begin understanding the regulatory context of tobacco use in retirement homes in the Province. A stratified random sample of retirement homes (n = 75) was selected. A rubric was developed highlighting various components that a model policy would include, to allow for the independent review of municipal-level bylaws governing these 75 homes. Results indicate that 75% of retirement homes were located in areas without municipal-level tobacco legislation that addressed retirement homes. The remaining 25% (n = 19 retirement homes) were governed by eight different municipal-level bylaws, all of which lacked in overall comprehensiveness. Amending Ontario's regulatory framework to eliminate loopholes and include retirement homes, as well as the creation and modification of municipal-level legislation, will aid in safeguarding smokers and nonsmokers from the dangers of tobacco-related risks, including secondhand smoke, fires, igniting cigarettes while connected to oxygen, burns to skin, and damage to clothing and property.

    2014-01-01

    A comprehensive survey of respirable dust and respirable silica in Ontario gold mines was conducted by the Ontario Ministry of Labor during 1978-1979. The aim was to assess the feasibility of introducing gravimetric sampling to replace the assessment method which used konimeters, a device which gave results in terms of number of particles per cubic centimeter (ppcc) of air. The study involved both laboratory and field assessments. The field assessment involved measurement of airborne respirable dust and respirable silica at all eight operating gold mines of the time. This article describes the details of the field assessment. A total of 288 long-term (7-8 hr) personal respirable dust air samples were collected from seven occupational categories in eight gold mines. The respirable silica (α-quartz) was determined by x-ray diffraction method. The results show that during 1978-1979, the industry wide mean respirable dust was about 1 mg/m(3), and the mean respirable silica was 0.08 mg/m(3.)The mean% silica in respirable dust was 7.5%. The data set would be useful in future epidemiological and health studies, as well as in assessment of workers' compensation claims for occupational diseases such as silicosis, chronic obstructive pulmonary disease (COPD), and autoimmune diseases such as renal disease and rheumatoid arthritis.

    2000-01-01

    The conditions and approaches required for a successful implementation of economic instruments in Ontario are reviewed. The advantages and disadvantages of economic instruments are discussed, as are some design issues. Some best practices and practical experiences from Canada, the United States, and Europe are examined through the use of nine specific case studies. Each one highlights a different environmental challenge, such as energy efficiency, air pollution, water pollution, waste management along with the solutions that were implemented. The situations described were not all successful, but there is much to be learned from unsuccessful episodes. Lessons learned from the review of the case studies were presented. The points to ponder when using economic instruments in Ontario were highlighted. The command and control policy instrument must be kept in context when considering economic instruments. The reasons that underline the preference of the economic theory for economic instruments are discussed. The different types of economic instruments are described, and the considerations related to the design and comparison of economic instruments is briefly discussed. The authors concluded with several points to ponder: there are a number of options available, details must not be neglected, consultation with the interested parties is important, there is a need for frequent reassessment, and using a number of instruments is helpful. 55 refs., tabs., figs

    This study determined the prevalence of diseases and pathogens associated with mortality or severe morbidity in 72 Ontario beef feedlots in calves that died or were euthanized within 60 days after arrival. Routine pathologic and microbiologic investigations, as well as immunohistochemical staining for detection of bovine viral diarrhea virus (BVDV) antigen, were performed on 99 calves that died or were euthanized within 60 days after arrival. Major disease conditions identified included fibrinosuppurative bronchopneumonia (49%), caseonecrotic bronchopneumonia or arthritis (or both) caused by Mycoplasma bovis (36%), viral respiratory disease (19%), BVDV-related diseases (21%), Histophilus somni myocarditis (8%), ruminal bloat (2%), and miscellaneous diseases (8%). Viral infections identified were BVDV (35%), bovine respiratory syncytial virus (9%), bovine herpesvirus-1 (6%), parainfluenza-3 virus (3%), and bovine coronavirus (2%). Bacteria isolated from the lungs included M. bovis (82%), Mycoplasma arginini (72%), Ureaplasma diversum (25%), Mannheimia haemolytica (27%), Pasteurella multocida (19%), H. somni (14%), and Arcanobacterium pyogenes (19%). Pneumonia was the most frequent cause of mortality of beef calves during the first 2 months after arrival in feedlots, representing 69% of total deaths. The prevalence of caseonecrotic bronchopneumonia caused by M. bovis was similar to that of fibrinosuppurative bronchopneumonia, and together, these diseases were the most common causes of pneumonia and death. M. bovis pneumonia and polyarthritis has emerged as an important cause of mortality in Ontario beef feedlots.

    Paramyxovirus-1 (PMV-1) infection was diagnosed in racing pigeons in Ontario during 1985, but it was not until January 1989, that the virus was isolated from feral pigeons (Columba livia) in this province. During an 18 month period beginning January 1988, a total of 43 feral pigeons was submitted to the Wildlife Diseases Laboratory, Pathology Department, Ontario Veterinary College. A history of neurological signs accompanied most of the birds. Tissues from 29 birds were submitted for PMV-1 isolation. Allantoic inoculation of embryonated chicken eggs yielded PMV-1 in 10 of the pigeons submitted. On the basis of histological criteria, we believe that 12 other birds were also infected with PMV-1. Gross pathological changes were unremarkable. Lymphplasmacytic interstitial nephritis was observed histologically in all birds from which PMV-1 was isolated. Other lesions seen, in decreasing frequency of occurrence, were lymphoplasmacytic interstitial hepatitis and multifocal hepatic necrosis, lymphoplasmacytic interstitial pancreatitis, nonsuppurative encephalitis and myelitis. The existence of PMV-1 in feral pigeons poses a potential threat to the poultry population since there is ample opportunity for mingling with poultry under open housing management. There is also a concern that pigeons may harbor the virus, perhaps in the kidney, and become chronic carriers and potential long-term disseminators of the disease. ImagesFigure 1.Figure 2.

    There is no reliable estimate of costs incurred by motorcycle crashes. Our objective was to calculate the direct costs of all publicly funded medical care provided to individuals after motorcycle crashes compared with automobile crashes. We conducted a population-based, matched cohort study of adults in Ontario who presented to hospital because of a motorcycle or automobile crash from 2007 through 2013. For each case, we identified 1 control absent a motor vehicle crash during the study period. Direct costs for each case and control were estimated in 2013 Canadian dollars from the payer perspective using methodology that links health care use to individuals over time. We calculated costs attributable to motorcycle and automobile crashes within 2 years using a difference-in-differences approach. We identified 26 831 patients injured in motorcycle crashes and 281 826 injured in automobile crashes. Mean costs attributable to motorcycle and automobile crashes were $5825 and $2995, respectively ( p motorcycle crashes compared with automobile crashes (2194 injured annually/100 000 registered motorcycles v. 718 injured annually/100 000 registered automobiles; incidence rate ratio [IRR] 3.1, 95% confidence interval [CI] 2.8 to 3.3, p motorcycles v. 12 severe injuries annually/100 000 registered automobiles; IRR 10.4, 95% CI 8.3 to 13.1, p motorcycle in Ontario costs the public health care system 6 times the amount of each registered automobile. Medical costs may provide an additional incentive to improve motorcycle safety. © 2017 Joule Inc. or its licensors.

    To understand physiotherapists' roles and how they are enacted within Ontario primary health care (PHC) teams. Following a pragmatic grounded theory approach, 12 physiotherapists practising within Ontario PHC teams participated in 18 semi-structured in-depth in-person interviews. All interviews were audiotaped and transcribed verbatim, then entered into NVIVO-8. Coding followed three progressive analytic stages and was iterative in nature, guided by grounded theory. An explanatory scheme was developed. Physiotherapists negotiate their place within the PHC teams through five interrelated roles: (1) manager; (2) evaluator; (3) collaborator; (4) educator; and (5) advocate. These five roles are influenced by three contextual layers: (1) inter-professional team; (2) community and population served; and (3) organizational structure and funding. Canada's PHC mandate (access, teams, information, and healthy living) frame the contexts that influence role enactment. To fulfill the PHC mandate, physiotherapists carry out multiple roles that are based on a broad holistic perspective of health, within the context of a collaborative inter-professional team and the community, through an evidenced-informed approach to care. There appear to be multiple ways of successfully integrating physiotherapists within PHC teams, provided that role enactment is context sensitive and congruent with the mandate of PHC.

    Navigant Consulting is a large investor-owned management consulting firm specializing in energy-based and other networked and regulated industries across Canada. The company works with clients to create delivery and protect shareholder value in the face of uncertainty and change. This presentation discussed the issue of price volatility in competitive electricity markets. The points to keep in mind for pricing in competitive power markets is that: (1) electricity should be generated simultaneously with use, (2) rates in administered markets are average over some time period, (3) competitive pool markets do not average costs, (4) in competitive pool markets, prices are set in very short (hourly or less) intervals, (5) prices in competitive markets are more volatile than in administered markets for both economic and market structure reasons, and (6) the degree of volatility and price levels can change quickly. The Ontario power market was also discussed with reference to price volatility in Ontario and what this means for electricity customers. tabs., figs

    OBJECTIVE: To estimate the prevalence of anemia among First Nations children of northwestern Ontario. DESIGN: Retrospective review of all hemoglobin determinations between 1990 and 1992 in the Sioux Lookout Zone. SETTING: The Sioux Lookout Zone Hospital, a secondary care referral hospital for 28 remote First Nations communities in northwestern Ontario, affiliated with the University of Toronto's Sioux Lookout Program. PARTICIPANTS: All First Nations children age 3 to 60 months who had produced venipuncture or fingerprick blood samples between 1990 and 1992 (614 children had a total of 1223 hemoglobin determinations). MAIN OUTCOME MEASURES: Prevalence of anemia by age, sex, geographical location, and diagnosis. Anemia was defined as a hemoglobin value less than 110g/L. RESULTS: Prevalence of anemia peaked in the age range of 6 to 24 months with prevalence rates of 51.7% to 79.3%. Conditions most commonly associated with anemia were respiratory tract infections. Children living in communities in the western part of the Sioux Lookout Zone were 1.64 times more likely to have anemia (95% confidence interval 1.15, 2.35) than children in the other communities. CONCLUSIONS: Anemia appears to be a serious public health problem among preschool children in the Sioux Lookout Zone. PMID:9111982

    Purpose: To investigate the prevalence of total quality culture (TQC) within radiation therapy (RT) departments across Ontario, Canada. Methods: A prospective quantitative survey was distributed within RT departments across Ontario, Canada using the Miller Consulting Group Quality Culture survey. Findings: Ninety percent of managers (9/10) and 50% of employees (261/519) participated. There was concordance between managers and staff that overall RT departments exhibit a work culture that somewhat resembles TQC. Both groups scored 55% of the categories as somewhat agree with TQC and 9% of categories as no TQC. There was discordance in views for 36% of the categories, where managers scored a higher prevalence of TQC compared to their therapists. Larger RT departments (>50 employees) had more prevalence of discrepancy between group scores. Conclusions: This is the first study to report on the prevalence of TQC within RT departments. Strategies designed for on-going continuous improvement will benefit staff, RT managers, continuity of patient care and patient safety within RT departments.

    When households, institutional and commercial buildings, industry, and especially auto transportation use fossil fuel based energy, they generate carbon dioxide emissions. Considering the environmental concerns and the soaring fuel prices, this could be the opportunity for the municipal fleet operator to assume a leadership position regarding environmental issues and look for new cost efficiencies. To begin, a meticulous examination of the fuel expenditures, a good management approach of fleet operations and a clearly defined system or guidance for lowering fleet fuel costs would be helpful for municipal fleet managers. This document is involved in a pilot program aimed at helping Ontario municipalities understand and promote fleet efficiencies and obtain related environmental benefits. Existing and cost-effective automotive fleet management policies and practices that can mitigate pollution causing global warming are given in this guide. These policies and practices also allow money savings and contribute to a better workplace health and livability of the community. This document is based on the experience of fleet management experts and local governments in Ontario. 54 refs.

    1998-01-01

    The government of Ontario is a shareholder in Ontario Hydro and is responsible for ensuring that the public receives electricity service at the lowest, most prudent price. The current monopoly arrangement provides Ontario with a revenue stream that is predictable and amenable to control. However, the emerging restructuring of Ontario's electricity supply system will be strongly dependent on the direction determined by government policy. Other factors that will have significant influence on developments will be the restructuring initiatives outside the province, and the attractiveness of the electricity sector to investors. In November 1997, Ontario released a white paper by the Minister of Energy, Science and Technology, entitled 'Direction for change'. This document is a preliminary statement of potential policy regarding electricity restructuring in Ontario. Some of the key elements of the White Paper were: (1) the creation of a competitive market in the year 2000 for both wholesale and retail customers, (2) separating monopoly operations from competitive business activities throughout the electricity sector, (3) expanding the role on the Ontario Energy Board to give it regulatory power over the electricity sector, and (4) introducing measures to ensure environmental protection. Three other relevant reports were also released in December 1997: (1) Report of the Select Committee on Ontario Hydro Nuclear Affairs, (2) Ontario Energy Board Advisory Report on Legislative Change Requirements for Natural Gas Deregulation, and (3) Report of the Toronto Transition Team. The government policy indicated by these various reports appear to represent a careful balance of many conflicting interests and obligations. According to expert observers, the emerging policy appears to have the necessary technical, financial and political support to ensure a successful competitive electricity supply system in Ontario. 4 refs

    Although stable, intraplate region of eastern Canada is considered low rate deformation area in the North American plate, the retreat of large ice sheets during deglaciation in the last 20 ka has resulted in horizontal and vertical deformation of the Earth's in eastern Ontario. Present-day glacial isostatic adjustment (GIA) uplift rates approach 10 mm/yr or more at Hudson Bay and decrease with distance southeastward. Current GIA models forecast that the hinge line between uplift to the northwest and subsidence to the southeast lies somewhere near the Saint Lawrence valley in eastern Canada [Tushingham and Peltier, 1991; Peltier, 2002]. Employing continuous Global Positioning System (cGPS) observations and high precision tools for processing and then analyzing each component of derived time series are important tools to monitor the associated regional crustal deformation with good accuracies. Here we describe the analysis of coordinate time series of cGPS stations scattered sparsely throughout southeastern Ontario and between Ottawa and the east coast of Hudson Bay. Here, the two most reliable local networks, each including 4 to 6 reference stations, were selected for analysis. Data for period of approximately five years, 2008-2012.9, was processed with Bernese 5.0 over several campaigns. Individual cGPS coordinate time series were generated for each station and basic parameters, such as mean, variance and repeatability, were estimated. The time series are corrected with respect to the rigid plate motion and seasonal variations and advanced time series analysis techniques, including spectral analysis and principal component analysis were implemented. Post-processing of the time series reproduces the general GIA spatial pattern. Results also show that the vertical velocities of all stations in the solution are consistent with the GIA model uplift rate and are consistent with other cGPS sites in eastern Canada and increases from north of lake of Ontario (approximately

    Avian metapneumovirus (aMPV) is an emerging poultry pathogen that has a significant economic impact on poultry production worldwide. The geographic range of the virus continues to expand, and wild birds have been implicated as reservoirs of aMPV that have the potential to spread the virus over long distances. Our objective was to determine the apparent prevalence of aMPV subtype C in wild waterfowl in Ontario, Canada. Wild waterfowl were captured in August and September, 2016 as part of routine migratory waterfowl population monitoring by the Ontario Ministry of Natural Resources and Forestry. Oropharyngeal and cloacal swabs were collected from each bird and placed together for aMPV testing using real-time RT-PCR. A total of 374 live wild birds from 23 lakes were sampled and tested for aMPV. Among all ducks tested, 84 (22%) were positive for aMPV. The proportion of samples that tested positive ranged from 0% in ring-necked ducks (Aythya collaris) and green-winged teal (Anas carolinensis) to 44% (8 of 18) in American black ducks (A. rubripes). Waterfowl positive for aMPV were found at 14 of 23 lakes in the study area and the percent positive at these 14 lakes ranged between 5% and 84%. Although subtype C aMPV has been detected in a variety of wild birds in North America, this is the first report of aMPV in wild ducks in Ontario, Canada. The high apparent prevalence, particularly in mallards and American black ducks (37 and 44%, respectively), suggests that these species may be important reservoirs of aMPV. Given the potential impact of aMPV on domestic poultry and the potential role of wild birds as reservoirs of the virus, further investigation of the geographic distribution, risk factors associated with aMPV carriage in wild waterfowl and potential role of other birds in the epidemiology of aMPV in Canada is warranted. © 2018 Blackwell Verlag GmbH.

  3. Mercury rising : mercury emissions from Ontario Power Generation's coal-fired plants

    Rang, S.

    2004-09-01

    Ontario Power Generation (OPG) operates 5 coal-fired power plants which are the largest single source of mercury emissions in Ontario. Mercury is a persistent, bioaccumulative neurotoxin which is considered toxic under the Canadian Environmental Protection Act. This report examines the health and environmental impacts of mercury, and the trends for mercury emission in Ontario. In 2002, the 5 coal-fired plants emitted 527 kg of mercury into the atmosphere and contributed 39 per cent of the total amount of mercury emitted into the air. While many other sectors have reduced their mercury emissions since 1988, Ontario's coal-fired plants have lagged behind and have actually increased mercury emissions by 16 per cent since 1988. This paper suggests that phasing out OPG coal-fired plants by 2007 could lead to a 39 per cent reduction in airborne mercury emissions. It would also allow Ontario to achieve the Canada Wide Standard for mercury emissions 3 years early, and would help both Ontario and Canada meet air pollution reduction commitments under international agreements. It was noted that phasing out coal-fired power plants by one-third will help Ontario achieve its goal of a 90 per cent reduction in mercury emissions by 2010. It was suggested that alternative power sources can offer a wide range of environmental advantages. 16 refs., 3 tabs., 2 figs

    An historical look at what triggered the creation of Imperial Oil`s joint industrial council (JIC) system was presented. A tragic episode known as the Ludlow massacre occurred in the spring of 1914 in a small coal-mining community in Colorado when striking coal miners were demanding recognition for the United Mine Workers Union to represent them in negotiations with the Colorado Fuel and Iron Company. The strike was overshadowed by skirmishes and gunfights. The death toll reached 200 by the time the strike was over. The tragedy triggered a series of events that would affect Canadian workers, including employees of Canada`s oldest oil company, Imperial Oil. William Lyon Mackenzie King a Canadian expert on labour law and policy, and later Canada`s longest-serving prime minister who led the nation during the Second World War, was consulted by the owner of the Colorado Fuel and Iron Company, John D. Rockefeller Jr. King set to develop some organization in the mining camps to ensure employees the right for collective bargaining and other advantages of membership in a union. King proposed the establishment of company or industry-sponsored boards or councils comprising delegates representing both management and wage-earning employees. Imperial Oil`s first JIC was inaugurated at the company`s refinery in Sarnia, Ontario on December 19, 1918. By 1921, 14 JICs covered all 6,000 employees in the company`s five refineries and six marketing divisions. The system enjoyed remarkable longevity. This year the JIC at the Sarnia Refinery will celebrate its 80. anniversary, evidence that the essential partnership of management and labour forged in 1918 was a durable one.

  5. Developments in steam generator leak detection at Ontario Hydro

    1998-01-01

    A method for locating small tube leaks in steam generators has been developed and implemented at Ontario Hydro. The technique utilizes both helium leak detection and moisture leak detection. The combination of these two methods allows tube leaks to be detected in any part of the tube bundle, including those submerged below water near the tubesheet. The estimated detection limits for the helium and moisture leak detection systems are 0.001 kg/hr and 0.05 kg/hr respectively, expressed as leak rates measured at typical boiler operating conditions. This technology is best utilized in situations where the leak rate under operating conditions is smaller than the practical limit for fluorescein dye techniques (∼2 kg/hour). Other novel techniques have been utilized to increase the reliability and speed of the boiler leak search process. These include the use of argon carrier gas to stabilize the buoyant helium gas in the boiler secondary. (author)

    1995-11-01

    A variety of options to reduce greenhouse gas emissions from the automotive sector in Ontario over the next decade were discussed. Each option was assessed in terms of practicality and implications for implementation. I was concluded that improvements in fuel economy anticipated from advancing technology, with or without new mandated standards, will not be enough to offset the impact of growth in vehicle fleet size and kilometres driven. If the goal is to stabilize greenhouse gas emissions, other measures such as reducing the fleet size and vehicle kilometres travelled and accelerated vehicle retirement (scrappage) programs must be considered. Key constraints on expansion of the alternative fuel fleet were identified. These include: (1) limited availability of an adequate range of alternative fuel vehicles at competitive prices, (2) limited refuelling facility infrastructure in the case of natural gas, limited range and fuel storage capacity for natural gas; (3)current limited fuel ethanol production capacity, and (4) market perceptions of performance, reliability and safety. tabs

    1988-01-01

    Scenarios for climatic change associated with a doubling of atmospheric carbon dioxide were employed in an assessment of the impacts of climate change on tourism and recreation in Ontario. A warmer climate resulting from such change may mean declining lake levels with associated changes in the ecological interest and recreational potential of wetlands, as shown by case studies on two parks near Great Lakes shorelines. In the skiing industry, the length of ski seasons will be reduced in the northern part of the province, but the key holiday periods (when a large portion of total business is conducted) should still fall within the reliable ski season. Further south, the ski season in the South Georgian Bay region could be eliminated. Summer recreational activities are likely to have extended seasons, and the viability of summer recreational enterprises may increase, with associated positive benefits to neighboring communities. 2 refs., 6 figs., 3 tabs

    West Nile virus encephalomyelitis was diagnosed in 28 horses presented to the Ontario Veterinary College Veterinary Teaching Hospital between August 20 and October 15, 2002. The age range of affected horses was 5 months to 20 years (mean 6.9 years, median 6 years). Clinical signs were highly variable. Duration of hospitalization ranged from < 1 to 12 days (mean 5 days, median 5.4 days). Overall, 16 of the 28 (57%) horses were discharged and, of the 14 from which follow-up information was available, 13 (93%) were reported to be clinically normal 4 to 6 weeks following discharge, while the other horse had markedly improved. This pathogen is emerging as an important cause of neurological disease in Canada. PMID:12839240

    During the period April 1983 to March 1986, lymphoreticular lesions in cattle were surveyed at an Ontario abattoir. Postmortem examination of 171,157 cattle revealed macroscopic lesions in 696 animals (0.4%). The most frequent finding was abscessation of a single lymph node, a finding that was observed in 353 cases (50.7% of animals with lesions/0.2% of total slaughter). Actinobacillary granulomas were present in 252 lymph nodes (36.2%/0.1%). Other specific lesions included mycobacteriosis and mycotic or parasitic lymphadenitis. Cases of nonspecific chronic lymphadenitis or granulomas in lymph nodes, pigmentations, malformations, hyperplasia, and neoplasia were also seen. Abscesses were the most common splenic lesions. One animal had localized lymphangiectasia of the epicardium. ImagesFigure 1., Figure 2., Figure 3., Figure 4., Figure 5., Figure 6. PMID:17423120

    Little is known about the risk of injury among adolescents who drive after the use of alcohol or cannabis or ride in cars driven by drunk drivers. We examined data from self-administered interviews with 1846 students in grades 7 to 13 who participated in the 2001 Ontario Student Drug Use Survey about their experiences related to alcohol, cannabis and driving during the 12 months preceding the survey. In all, 31.9% of the students reported being a passenger in a car driven by a drunk driver; of the students in grades 10 to 13 who had a driver's licence, 15.1% reported driving within an hour after consuming 2 or more drinks, and 19.7% reported driving within an hour after using cannabis. Our study shows that a sizeable proportion of adolescents are exposed to alcohol- and drug-related driving risks.

    Ontario Hydro (OH) is currently investigating the feasibility of using electrochemical techniques for the corrosion monitoring of service water systems. To date all evaluations have been carried out in a field simulator. The studies include examining the effects of; system startup after periods of stagnation, sodium hypochlorite injection, and zebra mussel settlement on metallic surfaces. Carbon steel and Type 304L stainless steel have been evaluated. Electrochemical potential noise (EPN), electrochemical current noise (ECN) potential and coupling current were semi-continuously monitored over a period of up to one year. Data obtained from the electrochemical noise monitoring has given OH valuable insights into the mechanisms of degradation in service water systems. The high sensitivity of the electrochemical noise technique, particularly to localized corrosion has proved to be the major attraction of the system

    1979-02-01

    Six fuel-cycle strategies for use in CANDU reactors are examined in terms of their uranium-conserving properties and their ease of commercialization for three assumed growth rates of installed nuclear capacity in Ontario. The fuel cycle strategies considered assume the continued use of the natural uranium cycle up to the mid-1990's. At that time, the low-enriched uranium (LEU) cycle is gradually introduced into the existing power generation grid. In the mid-2020's one of four advanced cycles is introduced. The advanced cycles considered are: mixed oxide, intermediate burn-up thorium (Pu topping), intermediate burn-up thorium (U topping), and LMFBR. For comparison purposes an all natural uranium strategy and a natural uranium-LEU strategy (with no advanced cycle) are also included. None of the strategies emerges as a clear, overall best choice.

    2011-01-01

    In April 2010, the Ontario government announced another reduction in the maximum price of generic drugs permitted under the Ontario Drug Benefit (ODB) program, demanding that generic drugs now be sold for no more than 25% of the branded product's price. Other provinces are following Ontario in setting unprecedentedly low price-caps to reduce the cost of generic drugs. Generic product substitution legislation is vital to reducing costs to provincial drug plans, yet lower and lower price-caps may undo some of the benefits of substitution legislation if generics find it difficult to survive.

Data is also grouped into large and small cities to establish if demographic success comes mostly from inter- or intraregional migrants. Relevant characteristics of individuals migrating in a knowledge economy, specifically education and employment data, are also examined. These findings are then placed within two important paradigms of economic geography, brain circulation and institutionalism. The intention is to measure migration patterns but also use these findings to re-evaluate the core-periphery model as it applies to northern and southern Ontario.

    This paper deals with the social construction of illegal drug use in the context of the counterculture movement. It looks at the actions and reactions of three groups in particular: the Ontario government, the Addiction Research Foundation of Ontario and citizens. It demonstrates that the debate about drug use took place in particular circumstances characterized by ignorance about the health consequences of illegal drug use but also within a moral panic context. Medical expertise was solicited to provide guidance to the Ontario government but it was gradually challenged by other medical groups and citizens who, by sending letters to their Provincial Premier and the Minister of Health, tried to shape public policy.

  18. Green tide: indoor marihuana cultivation and its impact on Ontario

    2003-07-01

    This paper discusses the apparent proliferation of marihuana grow-ops in Ontario over the last five years. Estimated revenues from indoor marihuana were detailed, as well as estimates of quantities of marihuana produced, forecasted trends and annual and weekly historical trends. The potential economic impact of this criminal activity was examined, with particular reference to increased police activities. The potential for fire and other human health risks included: exposure to mould associated with hydroponic cultivation and growth chemicals and higher concentrations of carbon dioxide and carbon monoxide. The socio-economic impact of grow ops were examined, with detailed estimates of law enforcement costs, insurance costs and costs to the justice system. Societal costs, such as environmental hazards, violence associated with organized crime, and the perceived threat to Ontario's children and communities were also outlined. Costs stemming from hydro theft were cited, including hydro repair and administration. Details of the bypass systems installed for hydro theft were also provided. It was concluded that it was unlikely that grow ops will be entirely eradicated. Measures that may limit the scope of grow ops included: developing avenues to increase effectiveness and efficiency of law enforcement approaches to grow ops, enhancing lines of communication and sharing of intelligence between police and other key stakeholders such as insurance companies, real estate agencies and banks and educating persons in the justice system on the issue of grow ops so that sentencing more accurately reflects the crime. It was recommended that lenient sentencing for marihuana possession and cultivation be re-examined. 70 refs., 12 tabs, 38 figs.

  19. Ontario-U.S. power outages : impacts on critical infrastructure

    International Nuclear Information System (INIS)

    2006-01-01

    This paper described the power outage and resulting blackout that occurred on August 14, 2003 and identified how critical infrastructure was directly and interdependently impacted in Canada. The aim of the paper was to assist critical infrastructure protection and emergency management professionals in assessing the potential impacts of large-scale critical infrastructure disruptions. Information for the study was acquired from Canadian and American media reports and cross-sectoral information sharing with provincial and federal governments and the private sector. The blackout impacted most of the sources and means of generating, transmitting and distributing power within the area, which in turn impacted all critical infrastructure sectors. Landline and cellular companies experienced operational difficulties, which meant that emergency responders were impacted. Newspapers and the electronic media struggled to release information to the public. The banking and finance industry experienced an immediate degradation of services. The power outage caused shipping and storage difficulties for commercial retailers and dairy producers. A number of incidents were reported where only partially treated waste water was released into neighbouring waterways. The timing of the blackout coincided with the closures of workplaces and created additional difficulties on transportation networks. Many gas station pumps were inoperable. Police, fire departments and ambulance services experienced a dramatic increase in the volume of calls received, and all branches of the emergency services sector encountered transportation delays and difficulties with communications equipment. Nuclear reactors were also impacted. An estimated 150,000 Government of Canada employees were unable to report to work. Estimates have indicated that the power outage cost Ontario's economy between $1 and $2 billion. The outage negatively impacted 82 per cent of small businesses in Ontario. 170 refs., 3 figs

  20. Aquatic dispersion modelling of a tritium plume in Lake Ontario

    Approximately 2900 kg of tritiated water, containing 2.3E+15 Bq of tritium, were released to Lake Ontario via the cooling water discharge when a leak developed in a moderator heat exchanger in Unit 1 at the Pickering Nuclear Generating Station (PNGS) on 1992 August 2. The release provided the opportunity to study the dispersion of a tritium plume in the coastal zone of Lake Ontario. Current direction over the two-week period following the release was predominantly parallel to the shore, and elevated tritium concentrations were observed up to 20 km east and 85 km west of the PNGS. Predictions of the tritium plume movement were made using current velocity measurements taken at 8-m depth, 2.5 km offshore from Darlington and using a empirical relationship where alongshore current speed is assumed to be proportional to the alongshore component of the wind speed. The tritium migration was best described using current velocity measurements. The tritium plume dispersion is modelled using the one-dimensional advection-dispersion equation. Transport parameters are the alongshore current speed and longitudinal dispersion coefficient. Longitudinal dispersion coefficients, estimated by fitting the solution of the advection-dispersion equation to measured concentration distance profiles ranged from 3.75 to 10.57 m 2 s -1 . Simulations using the fitted values of the dispersion coefficient were able to describe maximum tritium concentrations measured at water supply plants located within 25 km of Pickering to within a factor of 3. The dispersion coefficient is a function of spatial and temporal variability in current velocity and the fitted dispersion coefficients estimated here may not be suitable for predicting tritium plume dispersion under different current conditions. The sensitivity of the dispersion coefficient to variability in current conditions should be evaluated in further field experiments. (author). 13 refs., 7 tabs., 12 figs

    In recent years, Lean manufacturing principles have been applied to health care quality improvement efforts to improve wait times. In Ontario, an emergency department (ED) process improvement program based on Lean principles was introduced by the Ministry of Health and Long-Term Care as part of a strategy to reduce ED length of stay (LOS) and to improve patient flow. This article aims to describe the hospital-based teams' experiences during the ED process improvement program implementation and the teams' perceptions of the key factors that influenced the program's success or failure. A qualitative evaluation was conducted based on semistructured interviews with hospital implementation team members, such as team leads, medical leads, and executive sponsors, at 10 purposively selected hospitals in Ontario, Canada. Sites were selected based, in part, on their changes in median ED LOS following the implementation period. A thematic framework approach as used for interviews, and a standard thematic coding framework was developed. Twenty-four interviews were coded and analyzed. The results are organized according to participants' experience and are grouped into four themes that were identified as significantly affecting the implementation experience: local contextual factors, relationship between improvement team and support players, staff engagement, and success and sustainability. The results demonstrate the importance of the context of implementation, establishing strong relationships and communication strategies, and preparing for implementation and sustainability prior to the start of the project. Several key factors were identified as important to the success of the program, such as preparing for implementation, ensuring strong executive support, creation of implementation teams based on the tasks and outcomes of the initiative, and using multiple communication strategies throughout the implementation process. Explicit incorporation of these factors into the

  2. Types of Permeability Development in Carbonate Aquifers: Examples From Ontario

    Science.gov (United States)

    Worthington, S. R.

    2009-05-01

    Paleozoic carbonates are common in Ontario and form highly-productive aquifers that are widely utilized for water supplies. However, carbonates may have rapid groundwater velocities with little attenuation of bacterial contamination. One such example is at Walkerton, where more than 2000 people became ill and seven died after the municipal wells became contaminated with pathogenic bacteria. Subsequent studies showed that almost all the flow into the wells was from a few solutionally-enlarged fractures (or channels) at depths up to 70 m below the water table. Measured velocities from tracer tests to one of the municipal wells showed that groundwater velocities over distances up to 350 m were 200 - 500 m/day. This implies that there is an interconnected network of channels with apertures of at least 3 mm. An important question is whether such channel networks are common in carbonate aquifers. Advances over the last forty years have resulted in a clear understanding of how dissolution processes enhance aquifer permeability. First, laboratory experiments established that there is a precipitous drop in dissolution rates as chemical equilibrium is approached. Then numerical models showed how channel pathways become enlarged and integrated over time, forming self-organized networks that typically have apertures in the millimeter to centimeter range. The models have shown that two end-member channel network types may be distinguished, one with many channels of similar size (microkarstic aquifers) and one where a small number of large channels conduct most of the flow (macrokarstic aquifers). Macrokarstic development often occurs in Ontario where overburden is minimal and is manifested by sinking streams, springs, and occasionally caves; some dozens of examples have been documented. Microkarstic development is much more common; tracer tests suggest that natural-gradient groundwater velocities often exceed 30 m/day. Wide-ranging studies of bacterial contamination of wells

    Full Text Available Background: Chemical contaminants in the Canadian subarctic present a health risk with exposures primarily occurring via the food consumption. Objective: Characterization of soil contaminants is needed in northern Canada due to increased gardening and agricultural food security initiatives and the presence of known point sources of pollution. Design: A field study was conducted in the western James Bay Region of Ontario, Canada, to examine the concentrations of polychlorinated biphenyls, dichlorodiphenyltrichloroethane and its metabolites (ΣDDT, other organochlorines, and metals/metalloids in potentially contaminated agriculture sites. Methods: Exposure pathways were assessed by comparing the estimated daily intake to acceptable daily intake values. Ninety soil samples were collected at random (grid sampling from 3 plots (A, B, and C in Fort Albany (on the mainland, subarctic Ontario, Canada. The contaminated-soil samples were analysed by gas chromatography with an electron capture detector or inductively coupled plasma mass spectrometer. Results: The range of ΣDDT in 90 soil samples was below the limit of detection to 4.19 mg/kg. From the 3 soil plots analysed, Plot A had the highest ΣDDT mean concentration of 1.12 mg/kg, followed by Plot B and Plot C which had 0.09 and 0.01 mg/kg, respectively. Concentrations of other organic contaminants and metals in the soil samples were below the limit of detection or found in low concentrations in all plots and did not present a human health risk. Conclusions: Exposure analyses showed that the human risk was below regulatory thresholds. However, the ΣDDT concentration in Plot A exceeded soil guidelines set out by the Canadian Council of Ministers of the Environment of 0.7 mg/kg, and thus the land should not be used for agricultural or recreational purposes. Both Plots B and C were below threshold limits, and this land can be used for agricultural purposes.

    2015-01-01

    The dominant theme in the world energy market was the fall in oil prices in 2014. From 115 US-$/bbl in June it dropped to below 50 US-$/bbl in January 2015. Thereby the shale oil revolution has had the strong impact on the global energy situation, to this point has been predicted for three years. Although no one could predict the exact height of the fall in oil prices, but with oil as a reserve currency for all other fuels, it has not only had an impact on the gas and coal prices, but other commodities, such as copper, have also yielded. About cause and effect, there is a lot of speculation - not all of which are supported by wisdom. [de

  7. The role of LDCs in conservation and demand management in 2007 : the Ontario Clean Air Alliance's response to the Ontario Power Authority's options paper

    Gibbons, J.

    2006-01-01

    A response to The Ontario Power Authority (OPA) discussion paper on the role of local distribution companies (LDC) was presented, with reference to conservation and demand management (CDM). This paper examined 2 implicit issues raised by the OPA paper: (1) the appropriate role of the OPA with respect to conservation and demand management, and (2) the role of the Ontario Energy Board (OEB) in streamlining its CDM regulatory approval process. It was suggested that LDCs are ideal agencies for the delivery of CDM as they are trusted sources of energy information and have existing business relationships with electricity consumers. Local electric utilities understand local conditions and needs and are better placed to meet them. Ontario's electric utilities are now eligible for conservation profit bonuses equal to 5 per cent of the bill savings that their energy efficiency programs create for customers. It was noted that the benefits of CDM programs have already been demonstrated. The establishment of CDM budget targets was advised. Options to finance CDM programs were reviewed, as well as various energy efficiency programs. It was suggested that the OPA should continue to be a strong public advocate for CDM, and promote stricter provincial and federal energy efficiency standards. Recommendations for streamlining the OEB's CDM regulatory approval process were presented. It was concluded that marginalizing the role of Ontario's electric utilities in the delivery of CDM programs will short-circuit Ontario's efforts to develop a conservation culture. 13 refs

  8. Macro-economic benefits of an expanded oil sands industry

    International Nuclear Information System (INIS)

    1995-01-01

    Probable impact of benefits of expanded oil sands development on employment and government revenues were analyzed. Investment in proposed oil sands facilities was forecast to create about 1 million person-years of direct and indirect employment. Forty percent of employment gains would be created in Alberta, with remaining positions mostly in Ontario and Quebec. Government taxes, royalties, reduced debts interest costs and revenues to municipalities, hospitals and pension plans would increase by $97 billion (1994 dollars) between 1995 and 2025. Additional benefits would include increases in average Canadian disposable incomes, substitution of imported with domestic oil, and expansion of gross domestic product in Alberta by 5%. Some variation may be expected because of accuracy of assumptions that were made in the analysis, but the character of the results were not expected to change

    In 2004, the international media recognized Alberta's oil sands as part of the global oil reserves, thereby establishing Canada as second to Saudi Arabia as potential oil producing nations. The economic impacts of Alberta's oil sands industry on economies were assessed at regional, provincial and international levels for the 2000 to 2020 period. A customized input-output model was used to assess economic impacts, which were measured in terms of changes in gross domestic product; employment and labour income; and, government revenues. Cumulative impacts on employment by sector and by jurisdiction were also presented. An investment of $100 billion is expected through 2020, resulting in production of crude bitumen and synthetic crude oil outputs valued at about $531 billion. The impact of the oil sands industry on local employment was also evaluated. It was shown that activities in the oil sands industry will lead to significant economic impact in Alberta, Ontario, Quebec and the rest of Canada. Alberta's local economy would be the main beneficiary of oil sands activities with nearly 3.6 million person years employment created in Alberta during the 2000 to 2020. Another 3 million person years employment would be created in other Canadian provinces and outside Canada during the same time period. A sensitivity analysis on the responsiveness to oil prices and the removal of various constraints incorporated in the main analysis was also presented. The federal government will be the largest recipient of revenues generated to to oil sands activities. The results of the study were compared with that of the National Task Force on Oil Sands Strategies. This first volume revealed the results of the study while the second volume includes the data and detailed results. 48 refs., 57 tabs., 28 figs

    This study focused on the environmental impacts of fossil-fired generation that is expected to be displaced by electrical efficiency improvement programs and higher efficiency standards in the province on Ontario by the year 2000. Air emission dispersions were modelled by generating station. The impacts of air emission reductions on human mortality, human morbidity, building materials, agricultural crops, forests and lakes and fisheries were quantified using dose-response functions taken from the literature or estimated for the province of Ontario. Environmental impacts were monetized using cost data specific to Ontario. The final outcome was an estimate of the environmental benefits associated with emission reductions in fossil-fuelled power plants due to efficiency improvements in electricity use in the province of Ontario.

    2011-01-01

    The production of biogas through the anaerobic digestion of cattle manure and its subsequent use in the generation of electricity on larger farms in Ontario is currently economically attractive. This is a result of the Ontario Feed-In Tariff (FIT) program, which provides incentivized rates for the production of electricity from biogas. Although larger farms can take advantage of the higher rates for electricity, there are substantially more smaller farms for which individually designed and engineered biogas systems would be prohibitively expensive. By employing the concept of modular biogas plants, this analysis evaluates the economics of small-scale biogas utilization systems. Dairy farms with at least 33 animals and beef farms with at least 78 animals can operate economically attractive biogas systems. This analysis shows that approximately 9000 additional Ontario cattle farms would be able to take advantage of the FIT program, which would add 120 MW e of renewable energy capacity to the Ontario electrical grid.

    Full Text Available Rural emergency departments (EDs are important safety nets for the 20% of Canadians who live there. A serious problem in access to health care services in these regions has emerged. However, there are considerable geographic disparities in access to trauma center in Canada. The main objective of this project was to compare access to local 24/7 support services in rural EDs in Quebec and Ontario as well as distances to Levels 1 and 2 trauma centers.Rural EDs were identified through the Canadian Healthcare Association's Guide to Canadian Healthcare Facilities. We selected hospitals with 24/7 ED physician coverage and hospitalization beds that were located in rural communities. There were 26 rural EDs in Quebec and 62 in Ontario meeting these criteria. Data were collected from ministries of health, local health authorities, and ED statistics. Fisher's exact test, the t-test or Wilcoxon-Mann-Whitney test, were performed to compare rural EDs of Quebec and Ontario.All selected EDs of Quebec and Ontario agreed to participate in the study. The number of EDs visits was higher in Quebec than in Ontario (19 322 ± 6 275 vs 13 446 ± 8 056, p = 0.0013. There were no significant differences between Quebec and Ontario's local population and small town population density. Quebec's EDs have better access to advance imaging services such as CT scanner (77% vs 15%, p < .0001 and most the consultant support and ICU (92% vs 31%, p < .0001. Finally, more than 40% of rural EDs in Quebec and Ontario are more than 300 km away from Levels 1 and 2 trauma centers.Considering that Canada has a Universal health care system, the discrepancies between Quebec and Ontario in access to support services are intriguing. A nationwide study is justified to address this issue.

    2005-01-01

    In 2004, Ontario held 4 Requests for Proposals (RFPs) to encourage the development of new clean renewable combined heat and power generation and the implementation of conservation and demand management programs. Details of a stakeholder consultation related to the RFP process were presented were in this paper. The aim of the consultation was to synthesize stakeholder comments and to provide appropriate recommendations for future RFPs held by the Ontario Power Authority (OPA). The financial burden of bidding was discussed, as well as communications procedures and contract ambiguities. Issues concerning the criteria used for qualifying potential bidders and evaluating project submissions were reviewed. Recommendations for future processes included prequalification, a simplification in collusion requirements, and a fixed time response. It was also recommended that the process should not emphasize financing as lenders do not make firm commitments to bidders prior to a bid being accepted. It was suggested that the amount of bid security should vary with the project size and phase of development, and that the contracts for differences format should be refined to allow participants to propose parameters. Issues concerning audit procedures and performance deviations were reviewed. It was suggested that contract terms should be compatible with gas markets. It was also suggested that the OPA should adopt a more simplified approach to co-generation proposals, where proponents can specify amounts of energy and required prices. The adoption of the Swiss challenge approach of allowing other vendors an opportunity to match or beat terms on an offer was recommended. It was suggested that renewables should be acquired through a targeted and volume limited standard-offer process to be set yearly. Conservation and demand management recommendations were also presented. It was suggested that the OPA should serve as a facilitator of clean development mechanism (CDM) programs. It was

    Full Text Available Introduction: A lack of identifiers in health administrative databases limits our understanding of the cancer burden in First Nations. This study compares cancer risk factors and screening between First Nations in Ontario (on and off reserve and non-Aboriginal Ontarians using two unique health surveys. Methods: We measured age-standardized prevalence estimates using the First Nations Regional Health Survey (RHS Phase 2, 2008/10 (for First Nations on reserve and the Canadian Community Health Survey (CCHS, 2007–2013 (for First Nations off reserve and non-Aboriginal Ontarians. We used prevalence rate ratios (RR and Pearson’s chisquare tests for differences in proportions to compare estimates between First Nations (on and off reserve and non-Aboriginal Ontarians. Results: A higher proportion of First Nation men, women and adolescents on reserve smoked (RR = 1.97, 2.78 and 7.21 respectively and were obese (RR = 1.73, 2.33 and 3.29 respectively compared to their non-Aboriginal counterparts. Similar patterns were observed for First Nations off reserve. Frequent binge drinking was also more prevalent among First Nation men and women living on reserve (RR = 1.28 and 2.22, respectively and off reserve (RR = 1.70 and 1.45, respectively than non-Aboriginal Ontarians. First Nation men and women on reserve were about half as likely to consume fruit at least twice per day and vegetables at least twice per day compared to non-Aboriginal men and women (RR = 0.53 and 0.54, respectively. Pap test uptake was similar across all groups, while First Nation women on reserve were less likely to have had a mammogram in the last five years than non-Aboriginal women (RR = 0.85. Conclusion: First Nations, especially those living on reserve, have an increased risk for cancer and other chronic diseases compared to non-Aboriginal Ontarians. These results provide evidence to support policies and programs to reduce the future burden of cancer and other chronic diseases in

    Forest firefighters are faced with multiple physical and psychological challenges as a result of their duties. Little is known about the determinants of injury among these workers. The Ontario Ministry of Natural Resources (OMNR) Aviation, Forest Fire and Emergency Services (AFFES) records detailed information on two mutually exclusive types of workplace injury: First aid (self-reported) and Workplace Safety Insurance Board (WSIB, i.e. received medical attention). To identify the contributions of physical and psychological factors on the likelihood of injury among forest firefighters. Participants were male and female forest firefighters aged between 18 and 65. Data were collected using two self-administered instruments: The NEO Personality Inventory and the Job Stress Survey. Secondary data were collected from the OMNR AFFES and data were analysed by way of multivariate statistical procedures. There were 252 participants. Those who were older, had a history of injury, had high scores for the personality construct of Neuroticism or low scores for the Openness construct were significantly more likely to incur a first aid injury, while those with high experience levels were significantly less likely to incur injury (P stress was the only significant predictor of WSIB injury (P stress, personality and the prior occurrence of injuries in their assessment of risk. © The Author 2014.

    1992-01-01

    Tritium is a by-product of CANDU heavy water reactor operations and is the major contributor to internal dose for plant workers. The Darlington Tritium Removal Facility (DTRF) is decontaminating heavy water by removing tritium and storing it as a metal hydride. In view of the large tritium separation capacity, (24 MCi/a, 888 PBq/a). This paper reports that Ontario Hydro is interested in pursuing markets for the peaceful uses of tritium. One of these peaceful uses is in self-luminous lighting. The state of the art at present is a phosphor coated tube filled with tritium gas. However, safety considerations have restricted the use of these lights to outdoor or essential safety applications. Binding the tritium to a solid non-volatile matrix would increase the safety of tritium lights and allow the use of other phosphors, matrices and construction geometries. Solid, organic based tritium lights were produced using two different polymer matrices. While both these materials produced visible light, the intensity was low and radiolytic damage to the polymers was evident

The mine selected for the study was that of Agnew Lake Mines Limited in Northern Ontario. This is a relatively new mine with the combined mine/mill facilities first operational in mid-1977. Uranium is recovered from broken ore by in-situ leaching. The ventilation study was divided into two phases. A laboratory study was undertaken to develop a practical sampling technique, provide an evaluation of the logistics of long range sample transport and develop a laboratory analytical technique. Field programmes demonstrated the SF 6 tracer gas technique for mine ventilation trouble-shooting with the intent of providing information which will lead to more efficient use of existing mine ventilation capacity. This report outlines the findings of the laboratory study and the two field programmes

  6. A departmental brief to the Ontario Nuclear Safety Review

    1987-09-01

    The major nuclear activity in Canada is that associated with the generation of electricity by nuclear power stations. This area is in part subject to federal jurisdiction under the authority of the Atomic Energy Control Board. Environment Canada can play a significant role in influencing decisions regarding environmental aspects of nuclear energy development. The Department believes that the best way to preserve the quality of the environment is to anticipate and prevent problems before they arise. However, even if all precautionary measures were taken in the design and operating procedures of nuclear power stations, accidents can occur and radionuclides and toxic pollutants may escape and disperse into the environment. This brief outlines the rationale for Environment Canada's involvement and role in the nuclear area, and the major programs and activities of the Department with respect to environmental protection and emergency preparedness. The brief also makes recommendations for consideration of environmental protection technologies for nuclear power stations, for improved measurement and modelling capabilities relating to release and dispersion of radionuclides during accident conditions, and for improved communication with the public following a nuclear emergency. Environment Canada recommends that an appropriate environmental review process be undertaken for new or expanded nuclear facilities in Ontario

    Managing ageing steam generators involves costly decisions for the utility, both in terms of the cost of the maintenance activities andin terms of having the unit shutdown and consequent power loss while performing these activities. The benefits of these activities are seldom guaranteed and are sometimes very intangible. For nuclear utilities the most pertinent questions that arise are have we identified all the problem(s), can we predict the risk due to these problems? Can we implement corrective and preventive activities to manage the problem and what is the optimum timing of implementation? Is the money spent worthwhile, i.e. has it given us a return in production and safety? Can we avoid surprises? How can we tangibly measure success? This paper touches briefly on all the questions mentioned above but it mainly addresses the last question: 'how can we tangibly measure success?' by using several success indicators proposed by EPRI and by applying them to actual Ontario Hydro experience. The appropriateness of these success indicators as the means to assess the success of these programs, to feed back the results, and to enhance or revise the programs will be discussed. (author)

    On May 31, 2006, Ontario joined a small group of international jurisdictions to implement legislative restrictions on tobacco point of sale promotions. This study compares the presence of point of sale promotions in the retail tobacco environment from three surveys: one prior to and two following implementation of the legislation. Approximately 1,575 tobacco vendors were randomly selected for each survey. Each regionally-stratified sample included equal numbers of tobacco vendors categorized into four trade classes: chain convenience, independent convenience and discount, gas stations, and grocery. Data regarding the six restricted point of sale promotions were collected using standardized protocols and inspection forms. Weighted estimates and 95% confidence intervals were produced at the provincial, regional and vendor trade class level using the bootstrap method for estimating variance. At baseline, the proportion of tobacco vendors who did not engage in each of the six restricted point of sale promotions ranged from 41% to 88%. Within four months following implementation of the legislation, compliance with each of the six restricted point of sale promotions exceeded 95%. Similar levels of compliance were observed one year later. Grocery stores had the fewest point of sale promotions displayed at baseline. Compliance rates did not differ across vendor trade classes at either follow-up survey. Point of sale promotions did not differ across regions in any of the three surveys. Within a short period of time, a high level of compliance with six restricted point of sale promotions was achieved.

    An outbreak of fowl pox, which occurred in south-eastern Ontario between July 1988 and April 1989, was investigated in the spring of 1989 to determine factors associated with the spread of the disease. Clinical fowl pox was confirmed on five farms (cases). Twenty-seven farms, out of 35 egg producers with quota from Durham region to Northumberland county, provided information as controls. Bivariate analyses were performed on mail survey data using Fisher's exact test and odds ratios. Although the tests of hypotheses lacked statistical power because of the small number of case farms, and barns, a number of significant associations were found. At the farm level, fowl pox infection was associated with pullets purchased from a particular pullet grower. At the barn level, fowl pox infection was associated with pullets from a particular grower, mixing different groups of pullets, and a trend towards having birds early in the laying period, and higher numbers of birds placed. Fowl pox-infected barns had higher mortality and lower egg production postoutbreak. The results may indicate that the virus enters the laying barn at, or near, the time new birds are placed. Better communication among producers, catch-and-fill crews, and others associated with the egg industry, as well as more complete records of dates, sources, and persons involved with pullet placements, are recommended.

    Full Text Available To prevent further range recession, habitat features essential to the life-history requisites of woodland caribou (Rangifer tarandus caribou such as calving and nursery sites need to be protected for the persistence of the species. Woodland caribou may minimize predation risk during calving by either spacing out or spacing away from predators in the forest to calve on islands, wetlands, or shorelines. Our objective was to determine the characteristics of shoreline habitats used as calving and nursery sites by female woodland caribou in northern Ontario. Detailed vegetation and other site characteristics were measured at nursery sites used by cow-calf pairs in Wabakimi and Woodland Caribou Provincial Parks for comparison with shoreline sites that were not used by caribou within each park. Differences in habitat variables selected by female caribou in the two study areas reflect broad ecoregional differences in vegetation and topography. In Wabakimi Provincial Park, understorey tree density and ground detection distance played key roles in distinguishing nursery sites from sites that were not used. In Woodland Caribou Provincial Park, groundcover vegetation and shrub density were important in the selection of nursery sites by female caribou. Generally, female caribou in both parks selected nursery sites with greater slope, lower shrub density but thicker groundcover vegetation, including greater lichen abundance, and higher densities of mature trees than shoreline sites that were not used. The identification of these important features for caribou nursery sites provides a basis for improving their protection in future management policies and legislation.

    In 2003, Ontario's newly elected provincial government announced ten commitments to environmental, social and economic sustainability in urban development patterns. This presentation discussed the smart growth alternative versus the consequences of the business as usual urban development scenario. The economic benefits of smart growth are reduced development costs, reduced public service costs, reduced transportation costs, economies of agglomeration, more efficient transportation, and support for industry. The social benefits of smart growth are improved transportation options, improved housing options, better community cohesion, preservation of cultural resources, and increased physical exercise for individuals. The environmental benefits of smart growth are increased green space, reduced air and water pollution, increased energy efficiency, reduced urban heat island effects, and reduced demand for aggregates. This report examined the government's progress in its commitment to sustainability in urban development. It provided a status report and commentary on infrastructure funding policies, land-use policies, taxation policies, and governance structures. It was concluded that in general, the new government has made a good start on issues related to urban sustainability. The critical actions that remain outstanding were listed. refs., tabs., figs.

  12. Linking traditional knowledge and environmental practice in Ontario.

    2009-01-01

    Beginning in the late 1980s with the release of Our Common Future by the World Commission on Environment and Development, followed by the development of international accords such as the 1992 Convention on Biological Diversity, international pressure to resolve Indigenous rights issues has been steadily mounting. Successive Canadian governments have been striving increasingly to recognize and incorporate Aboriginal traditional knowledge into resource management planning. Following more than a decade of such efforts, the question of how to achieve such incorporation appropriately remains inadequately answered. This essay contributes to the resolution of this issue by first clarifying some key differences between Aboriginal and non-Aboriginal definitions of "traditional knowledge." Then, three Ontario case studies are briefly described that highlight the most and least successful aspects of previous undertakings. Among the lessons learned are the need to value traditional knowledge on a par with Western science while recognizing the particular capabilities of each system, and the requirement that Aboriginal peoples and their knowledge participate on a mutually respectful basis.

    Ortech is a consulting firm that provides engineering services to investors and developers in planning and operating solar, wind and water projects. This study discusses the issues involved in the renewable energy Feed-in Tariff (FIT) program in Ontario. Initially hailed as the poster child of innovative renewable programs in North America, the FIT program has been under increasing attack from political parties, anti wind groups and legal suits. The reason was the negative media coverage of noise, birdlife and health effects. Criticism was first voiced over health concerns and lack of consultation. Local governments and the legislature debated these issues and began to split along political lines over them. The lack of public support was because there was insufficient effort put into creating public awareness. Boosting grass-roots support by creating awareness is a recommendation of the paper, which also emphasises the need for a win-win strategy when the government is involved. It can be concluded that the FIT program has gone from poster child to industry crisis but has provided several learning opportunities along the way.

  14. Steam generator life cycle management: Ontario Power Generation (OPG) experience

    International Nuclear Information System (INIS)

    A systematic managed process for steam generators has been implemented at Ontario Power Generation (OPG) nuclear stations for the past several years. One of the key requirements of this managed process is to have in place long range Steam Generator Life Cycle Management (SG LCM) plans for each unit. The primary goal of these plans is to maximize the value of the nuclear facility through safe and reliable steam generator operation over the expected life of the units. The SG LCM plans integrate and schedule all steam generator actions such as inspection, operation, maintenance, modifications, repairs, assessments, R and D, performance monitoring and feedback. This paper discusses OPG steam generator life cycle management experience to date, including successes, failures and how lessons learned have been re-applied. The discussion includes relevant examples from each of the operating stations: Pickering B and Darlington. It also includes some of the experience and lessons learned from the activities carried out to refurbish the steam generators at Pickering A after several years in long term lay-up. The paper is structured along the various degradation modes that have been observed to date at these sites, including monitoring and mitigating actions taken and future plans. (author)

    Understanding the sexual activities and partnerships of women living with human immunodeficiency virus (HIV) remains important to promote healthy sexuality and to reduce the transmission of HIV and other sexually transmitted infections. We described sexual behaviors of women living with HIV enrolled in an ongoing study in Ontario, Canada. Data were available from 582 women who self-completed a sexual behavior questionnaire between 2010 and 2012. Nearly half (46.1%) of women reported a sexual partner in the preceding three months; women less likely to be sexually active were older, Black/African, separated, divorced, widowed, single, and unemployed. Most sexually active women had one partner (76.4%), a regular partner (75.9%), male (96.2%) partner(s), and partners who were HIV-negative or unknown HIV status (75.2%). Women were more likely to use a condom with HIV-negative/status unknown partners (81.3%) than with HIV-positive partners (58.6%; p   =   .008). Only 8.0% of sexually active women reported condomless sex with a discordant HIV-negative/status unknown partner when their viral load was detectable. Overall, most women living with HIV were sexually inactive or engaged in sexual activities that were low risk for HIV transmission.

  16. Traditional Knowledge: Considerations for Protecting Water in Ontario

    2012-12-01

    Full Text Available In Canada, the water crisis increasingly felt around the world is being experienced primarily in small, usually Indigenous, communities. At the heart of this issue lies an ongoing struggle to have Indigenous voices heard in the decision-making processes that affect their lives, lands, and waters. As part of ancient systems of Traditional Knowledge (TK, Indigenous people bear the knowledge and the responsibility to care for the waters upon which they depend for survival. A series of internationally developed documents has supported Indigenous peoples’ calls for increased recognition of the importance of TK in resolving environmental crises, including those involving water. Ontario provincial and Canadian federal governments have been developing legislative and regulatory documents to help fend off further water-related catastrophes within their jurisdictions. Despite such efforts, a number of barriers to the successful and appropriate involvement of TK in water management remain. Based on years of community-based and policy-related research with First Nations people involved in water-related undertakings, this article highlights progress made to date, and provides Indigenous viewpoints on what further steps need to be taken. Key among these steps are the need to restore and maintain Indigenous access to traditional territories and ways of life, and the requirement for mutually respectful collaboration between TK and Western science.

  17. Mallard Use of Hen HousesTM in Eastern Ontario

    2006-06-01

    Full Text Available Nesting structures for ground-nesting waterfowl may be an effective technique for increasing nesting success in regions in which nest success is below the 15% threshold needed to maintain a stable population. We studied the occupancy rate of artificial nesting structures called hen housesTM by Mallards (Anas platyrhynchos nesting in two different wetland habitats, beaver ponds and sewage lagoons, in eastern Ontario during 1999-2001. We hypothesized that, because natural cover was sparse on sewage lagoons, Mallards would occupy hen houses at a higher rate on sewage lagoons than on beaver ponds. However, of the 248 hen houses distributed between beaver ponds and sewage lagoons, none was occupied by waterfowl. Common Grackles (Quiscalus quiscula were the only avian species that nested in hen houses. However, Mallards successfully nested directly under several structures (n = 6 when water levels were low enough to expose the ground beneath them. Mayfield daily nest survival estimates for Mallards nesting in natural cover were similar on sewage lagoons and beaver ponds for all years (mean = 0.99 and were higher than most published estimates. Factors such as nesting cover, predation pressures, and structure design and material may influence the use of artificial hen houses and should be considered when planning a hen house program outside of the Prairie Pothole Region.

    1986-09-01

    The purpose of this study was to estimate non-radiological risks of occupational fatalities in Ontario industries. The distribution of high-risk occupations was found to vary widely between the different industries for a number of reasons including the fact that insufficient data in some instances resulted in less than desirable reliability. However, in spite of various data limitations, a number of occupations had above average fatal risk rates in several industries, including Material Handlers and Related, N.E.C. (SOC-9319), Welders and Flame Cutters (SOC-8335), Truck Drivers (SOC-9175) and Mechanics and Repairmen, except Electrical (SOC-8589). The majority of occupations had rates below or close to the industry average; however, between 15% and 30% of the occupations in any given industry had fatal risk rates above the industry average. When the number of workers involved in different occupations was considered, between 18% and 40% of workers were in occupations with above average risk. Recommendations for future work are also provided

    2011-01-01

    The paper discusses the legal issues related to the Ontario FIT contract, which includes the FIT waiver agreement, WTO challenge, FIT extension, political risk assessment and issues related to unforeseen events beyond human control (force majeure). The risk of termination of the FIT waiver is omitted for convenience by OPA but timing implications relating to the FIT waiver are included. The binding agreement for supply of generating equipment is also presented and the term sheet for turbine equipment and bill of purchase being understood as binding agreements is questioned. Political risks relate to existing contracts, lawsuit risks and changes to the REA process. Change in government and the implications of minority government can be added to the political risks. A successful WTO challenge has been assumed and the possible implications are discussed. Some of them include risk to FIT contracts already issued; changes in DC requirements and in FIT contract pricing and re-pricing of construction and turbine equipment supply contracts if DC requirements are relaxed.

  20. Zebra mussels mitigation at Ontario Hydro's hydroelectric generating facilities

    1992-01-01

    The Great Lakes and their connecting channels have recently been invaded by a tiny freshwater mollusc that has already cost Ontario Hydro millions of dollars. Dreissena polymorpha, commonly known as the zebra mussel, entered the great lakes in ballast water carried by a ship from Europe in 1985. These mussels threaten to reduce or totally block the flow of water in auxiliary systems of any generating station, water treatment plant or municipal water facility that uses raw lake water and to cause accelerated corrosion of the metallic substrate to which they attach themselves. To satisfy the immediate need for control, chlorination was identified as the most effective interim measure to prevent the biofouling of the raw water systems. Detection and monitoring of mussels and the installation, operation, environmental constraints, benefits and deficiencies of the chemical treatment system are presented. Long term objectives for control of the mussels are to develop alternatives to chlorination (ozone, hydrogen peroxide, protective coatings, thermal shock, mechanical filtration, etc.) for application at existing facilities and for incorporation into the design of new facilities and rehabilitation programs. 3 refs., 5 figs

    2017-09-01

    A cluster of 12 cases of White Chick Syndrome (WCS) in broiler breeder flocks producing affected progeny occurred from June to November 2015 in two broiler chicken hatcheries owned by a single company in Ontario, Canada. Cases were identified by the presence of typical chicks in the hatchery characterized by pale to white down, enlarged abdomens, and occasionally brown wiry fluff on the dorsum of the neck that were generally weak. Affected broiler breeder flocks experienced egg production drops of 0% to 15% and hatchability drops of 1.8% to 49.1%. Some flocks experienced increased feed clean-up duration and/or reduced hatching egg weight. The financial impacts of WCS to affected hatching egg producers averaged $5,912 CAD (US$4,417) per 10 000 hens and were as great as $16,788 CAD (US$12,544) per 10 000 hens. The financial impacts of WCS to the affected hatcheries averaged $1,723 CAD (US$1,287) per 10 000 broiler breeder hens and were as great as $4,096 (US$3,060) per 10 000 hens.

    An historical look at what triggered the creation of Imperial Oil's joint industrial council (JIC) system was presented. A tragic episode known as the Ludlow massacre occurred in the spring of 1914 in a small coal-mining community in Colorado when striking coal miners were demanding recognition for the United Mine Workers Union to represent them in negotiations with the Colorado Fuel and Iron Company. The strike was overshadowed by skirmishes and gunfights. The death toll reached 200 by the time the strike was over. The tragedy triggered a series of events that would affect Canadian workers, including employees of Canada's oldest oil company, Imperial Oil. William Lyon Mackenzie King a Canadian expert on labour law and policy, and later Canada's longest-serving prime minister who led the nation during the Second World War, was consulted by the owner of the Colorado Fuel and Iron Company, John D. Rockefeller Jr. King set to develop some organization in the mining camps to ensure employees the right for collective bargaining and other advantages of membership in a union. King proposed the establishment of company or industry-sponsored boards or councils comprising delegates representing both management and wage-earning employees. Imperial Oil's first JIC was inaugurated at the company's refinery in Sarnia, Ontario on December 19, 1918. By 1921, 14 JICs covered all 6,000 employees in the company's five refineries and six marketing divisions. The system enjoyed remarkable longevity. This year the JIC at the Sarnia Refinery will celebrate its 80. anniversary, evidence that the essential partnership of management and labour forged in 1918 was a durable one

    Public awareness and concern for the potential short and long term impacts of oil spills on the marine environment has generally been high, particularly for regions of special ecological importance or where significant numbers of marine mammals and birds are present. This awareness was further heightened by the extraordinary number of recent large spills in coastal U.S. water: Exxon Valdez, Alaska; World Prodigy, Rhode Island; Presidente Rivera, Delaware; Rachel-B, Texas and American Trader, California. The occurrence of so many spills in a one year period is unprecedented in U.S. spill history. The legislative response to these spills has been immediate. New legislative initiative are rapidly being developed. Improved ways to organize spill response efforts are being devised and implemented. Funds are being allocated to further develop and improve spill response equipment and damage assessment methodologies. These spill events will have a significant impact in both the short and long term on oil exploration, development and transport in marine waters. They will result in major changes in management and operation of oil exploration and development. The purpose of this conference was to provide a forum for discussion of the changes which are currently taking place in oil spill legislation, management, and response strategies

    Increasing water clarity in Lake Ontario has led to a vertical redistribution of phytoplankton and an increased importance of the deep chlorophyll layer in overall primary productivity. We used in situ fluorometer profiles collected in lakewide surveys of Lake Ontario in 2008 to assess the spatial extent and intensity of the deep chlorophyll layer. In situ fluorometer data were corrected with extracted chlorophyll data using paired samples from Lake Ontario collected in August 2008. The deep chlorophyll layer was present offshore during the stratified conditions of late July 2008 with maximum values from 4-13 μg l-1 corrected chlorophyll a at 10 to 17 m depth within the metalimnion. Deep chlorophyll layer was closely associated with the base of the thermocline and a subsurface maximum of dissolved oxygen, indicating the feature's importance as a growth and productivity maximum. Crucial to the deep chlorophyll layer formation, the photic zone extended deeper than the surface mixed layer in mid-summer. The layer extended through most of the offshore in July 2008, but was not present in the easternmost transect that had a deeper surface mixed layer. By early September 2008, the lakewide deep chlorophyll layer had dissipated. A similar formation and dissipation was observed in the lakewide survey of Lake Ontario in 2003.

    1999-01-01

    Amid growing concerns about nitrogen oxide (Nox) emissions, the Ontario Clean Air Alliance is recommending in this report that the Ontario government restrict Nox emissions from Ontario Power Generation (OPG) in the year 2000 and not let the corporation meet its emissions cap by on a net basis by retiring Pilot Emission Reduction Trading (PERT) Nox emission reduction credits. Instead the alliance believes the Ontario government should require OPG to achieve emissions compliance by curtailing coal-fired electricity exports, purchasing renewable and natural-gas electricity and promoting energy efficiency. OPG's inventory of PERT Nox reduction credits are assessed against whether they will cause an increase in the year 2000 as a result of trading. Ontario Power Generation's Nox emissions are a central chemical component of acid rain and smog and are produced from its coal-fired electricity generators. The utility would like to achieve Nox reductions by establishing demand management programs which would reduce the demand for electricity by 5200 megawatts (MW), by purchasing 3100 MW of non-utility generation and by undertaking combustion process modifications at its Lambton and Nanticoke coal-fired generating stations. It has not met its 2000 demand management and non-utility generation targets, and specifically, as of December 31, 1998, Ontario Hydro's successor companies demand management programs have only reduced electricity demand by approximately 1300 MW. Furthermore, the successor companies will have only approximately 1700 MW of non-utility generation capacity under contract by December 31, 1999. The report describes the criteria for ensuring that Nox emissions trading will not lead to a net increase in Ontario's emissions in any given year, and a description is included of why the 'Draft Rules for Emission Trading in Ontario' rules do not meet these criteria. Permitting OPG to use its PERT credits to meet its Nox cap, will allow them to increase coal

    Phosphorus showed high variation across nearshore (10 m depth) sites but was more stable at offshore (20 m and deeper) stations. In June and July, sites at the mouth of the Niagara River and at Oak Orchard had high phosphorus concentrations (20 – 46 μg/L). Epilimnetic average April-Oct total phosphorus (TP) ranged between 6.9 and 19.9 μg/L in the nearshore and between 5.8 and 10.2 μg/L in the offshore. Average April-Oct soluble reactive phosphorus (SRP) ranged from 0.9 to 7.3 μg/L in the nearshore and 0.8 to 1.4 μg/L in the offshore. TP and SRP were significantly higher in the nearshore than in the offshore.Spring TP has declined in the longer data series (since 1981), but not since 1995. It averaged 8.4 μg/L in the nearshore and 5.0 μg/L in the offshore in 2013—below the 10 μg/L target set by the Great Lakes Water Quality Agreement of 1978 for offshore waters of Lake Ontario.Offshore summer chlorophyll-a declined significantly in both the short- (1995-2013) and long-term (1981-2013) time series at a rate of 3-4% per year. Nearshore chlorophyll-a increased after 2003 but then declined again after 2009. Epilimnetic chlorophyll-aaveraged between 0.5 and 1.3 μg/L across sites with no difference between nearshore and offshore habitats. Average seasonal Secchi disk depth ranged from 4.5 m to 10.6 m and was higher in the offshore (average 8.1 m) than nearshore stations (6.3 m). These values are indicative of oligotrophic conditions in both habitats.In 2013, Apr/May - Oct epilimnetic zooplankton size and total biomass were significantly higher in the offshore than the nearshore. However, with the exception of Limnocalanus (higher in offshore), there were no differences between habitats for any of the zooplankton groups.Most of the zooplankton biomass was in the metalimnion and hypolimnion during the day in 2013. Between 65 and 98% of zooplankton biomass was found below the thermocline throughout the year.The predatory cladoceran Cercopagis continued to be

    Soluble reactive phosphorus (SRP) concentrations have been stable in nearshore and offshore habitats since 1998 (0.4 – 3.3 μg/L). SRP concentrations were low in 2014; Apr/May – Oct mean values were Water Quality Agreement of 1978 for offshore waters of Lake Ontario. TP concentrations were low at both nearshore and offshore locations; Apr/May – Oct mean values from individual sites ranged from 4.6 – 9.1 μg/L. Spring TP has declined significantly in the longer data series (since 1981), but not since 1995 indicating stable nutrient loading into Lake Ontario for nearly two decades. It averaged 7.8 μg/L in the nearshore and 5.6 μg/L in the offshore in 2014.Chlorophyll-a and secchi depth values are indicative of oligotrophic conditions in nearshore and offshore habitats. Offshore summer chlorophyll-a declined significantly in both the short- (2000-2014) and long-term (1981-2014) time series at a rate of 4-6% per year. Nearshore chlorophyll-a increased after 2003 but then declined again after 2009. Epilimnetic chlorophyll-a averaged between 0.6 and 1.6 μg/L across sites with no difference between nearshore and offshore habitats. Apr/May – Oct Secchi depth ranged from 4.0 m to 10.8 m at individual sites and was higher in the offshore (average 9.1 m) than nearshore (5.9 m).In 2014, Apr/May – Oct epilimnetic zooplankton density, size, and biomass were not different between the offshore and the nearshore, and there were no differences in epilimnetic biomass between offshore and nearshore areas for any of the zooplankton groups.Zooplankton density and biomass peaked in September, an atypical pattern. This coincided with peaks in calanoid copepod, daphnid, and Holopedium biomass. Holopedium biomass in the nearshore increased significantly since 1995.The predatory cladoceran Cercopagis continued to be abundant in the summer, peaking at ~10 mg/m3in the offshore. Bythotrephes biomass was at its lowest level since 2005 in both offshore and nearshore habitats

    Amidst changing climates, understanding the world's water resources is of increasing importance. In Ontario, Canada, low water conditions are currently assessed using only precipitation and watershed-based stream gauges by the Conservation Authorities in Ontario and the Ministry of Natural Resources and Forestry. Regional groundwater-storage changes in Ontario are not currently measured using satellite data by research institutes. In this study, contributions from the Gravity Recovery and Climate Experiment (GRACE) data are compared to a hydrogeological database covering southern Ontario from 2003 to 2013, to determine the suitability of GRACE total water storage estimates for monitoring groundwater storage in this location. Terrestrial water storage data from GRACE were used to determine monthly groundwater storage (GWS) anomaly values. GWS values were also determined by multiplying groundwater-level elevations (from the Provincial Groundwater Monitoring Network wells) by specific yield. Comparisons of GRACE-derived GWS to well-based GWS data determined that GRACE is sufficiently sensitive to obtain a meaningful signal in southern Ontario. Results show that GWS values produced by GRACE are useful for identifying regional changes in groundwater storage in areas with limited available hydrogeological characterization data. Results also indicate that GRACE may have an ability to forecast changes in groundwater storage, which will become useful when monitoring climate shifts in the near future.

    Ontario has embarked upon a program to restore elk (Cervus elaphus) that were once native to that province. A comprehensive disease-management strategy has ensured that elk are free of infectious diseases such as brucellosis and tuberculosis prior to shipment to Ontario. Postmortem analysis occurs on elk mortalities in Ontario to ensure that elk are not infected with diseases such as chronic wasting disease and tuberculosis. Between 1998 and 2001, a total of 443 elk were transported from Elk Island National Park, Alberta, and released in four different areas of Ontario. Cumulative mortality for elk in all areas was 26% from 1998 to January 2001. The primary causes of mortality were post-release stress-induced emaciation (21%), wolf predation (20%), transport/handling injuries (10%), bacterial infections (10%), and drowning (7%). Female calves had the highest mortality rates (37%) compared to the other sex and age cohorts (23-24%). Preliminary findings suggest an inverse correlation between the length of time elk are held in enclosures prior to release and the distance they disperse from the release site. The 2001 estimated population of elk in Ontario is about 400 individuals.

    This paper uses support vector machines (SVM) based learning algorithm to select important variables that help explain the real-time peak electricity price in the Ontario market. The Ontario market was opened to competition only in May 2002. Due to the limited number of observations available, finding a set of variables that can explain the independent power market of Ontario (IMO) real-time peak price is a significant challenge for the traders and analysts. The kernel regressions of the explanatory variables on the IMO real-time average peak price show that non-linear dependencies exist between the explanatory variables and the IMO price. This non-linear relationship combined with the low variable-observation ratio rule out conventional statistical analysis. Hence, we use an alternative machine learning technique to find the important explanatory variables for the IMO real-time average peak price. SVM sensitivity analysis based results find that the IMO's predispatch average peak price, the actual import peak volume, the peak load of the Ontario market and the net available supply after accounting for load (energy excess) are some of the most important variables in explaining the real-time average peak price in the Ontario electricity market.

    Ontario Hydro has undertaken several studies to assess any possible risk of cancer resulting from electromagnetic fields. Study results appear to support the conclusion that there is a risk of cancer to humans from electromagnetic fields. The risk is small. The conclusions of the National Institute of Environmental Health Sciences are supported by the Royal Society of Canada, monitoring the Electromagnetic Fields Risk Assessment Program of Ontario Hydro. The following three studies sponsored by Ontario Hydro showed evidence for concern regarding possible cancer risk associated with electromagnetic fields: (1) a study by Stuchly on the effect of 60 Hertz (Hz) electric and magnetic fields on the induced electric fields in the body; (2) a study on malignancies among employees of Ontario Hydro; and (3) a study of pediatric leukemia in Ontario. It was recommended that long term maximum exposure to high electromagnetic fields be limited by following the guidelines published by the International Committee on Non-Ionizing Radiation. 55 refs., 1 tab., 8 figs.

    1988-01-01

    In December 1986 a study of the safety of the design, operating procedures and emergency plans associated with Ontario Hydro's nuclear generating plants was commissioned by the government of the province of Ontario. After receiving briefs from many interested groups and individuals, visiting the power plants, and consulting with nuclear industry and regulatory representatives in Canada and other countries, the commissioner presented this report to the Minister of Energy for Ontario. His major conclusion is that Ontario Hydro reactors are being operated safely and at high standards of technical performance. No significant adverse impact has been detected in either the work force or the public. The risk of accidents serious enough to affect the public adversely can never be zero, but is very remote. Major recommendations are that: Ontario Hydro re-examine its operational organization closely and commission a study of factors affecting human performance; and, that priority be given to finding a solution to pressure tube performance problems and to improving in-reactor monitoring. Sixteen other recommendations are presented relating to research and development, information exchange with other organizations, reactor performance, training, severe accident analysis, the provincial nuclear emergency plan, epidemiological studies, the Atomic Energy Control Board, public hearings, and women in the nuclear industry

    2002-01-01

    In late 2002, the Ontario Premier announced a Nine-Point response to the competitive electricity regime in the province, which was followed by the release of draft legislation. This draft legislation called for a government imposed retail price cap of 4.3 cent kilo watt hour for the cost of energy, effective December 1, 2002 to 2006. In addition, the Premier indicated a retroactive refund would be forwarded to customers from May 1, 2002, for charges above the price cap. In this document, the author argued for a lessening of the price cap proposals, and supporting a market allowed to hold its course toward competitive markets in the future. The arguments put forth by the author were: (1) the imposition of price caps will hinder long-term economic viability in Ontario, (2) the benefits of competition cannot be interrupted by politically-motivated responses, (3) if the current path is followed Ontario may be headed towards blackouts, (4) deregulation is essential if Ontario is to remain competitive in the electricity marketplace, and (5) upcoming downgrade in Ontario's red index score. 3 tabs

    Multidisciplinary team approach is an essential component of evidence-based wound management in the community. The objective of this study was to identify and describe community-based multidisciplinary wound care teams in Ontario. For the study, a working definition of a multidisciplinary wound care team was developed, and a two-phase field evaluation was conducted. In phase I, a systematic survey with three search strategies (environmental scan) was conducted to identify all multidisciplinary wound care teams in Ontario. In phase II, the team leads were surveyed about the service models of the teams. We identified 49 wound care teams in Ontario. The highest ratio of Ontario seniors to wound team within each Ontario health planning region was 82,358:1; the lowest ratio was 14,151:1. Forty-four teams (90%) participated in the survey. The majority of teams existed for at least 5 years, were established as hospital outpatient clinics, and served patients with chronic wounds. Teams were heterogeneous in on-site capacity of specialized diagnostic testing and wound treatment, team size, and patient volume. Seventy-seven percent of teams had members from three or more disciplines. Several teams lacked essential disciplines. More research is needed to identify optimal service models leading to improved patient outcomes. © 2014 by the Wound Healing Society.

    This report presents recommendations made by Ontario's Electricity Conservation and Supply Task Force regarding changes that need to be made to Ontario's electricity system to meet future energy demands. Ontario faces a future shortage in supply as coal-fired generation and aging nuclear plants are taken out of service. The Task Force emphasized that early action is needed to ensure a reliable electricity supply and competitive prices. The chapters of the report present: the process and recommendations; the demand and supply outlook; a plan that works for consumers; a plan for delivering sustainable conservation; ensuring adequate supply; enhancing the reliability and responsiveness of Ontario's electricity grid; and, a framework to address Ontario's power needs. The report states that the market approach of the late 1990s needs improvement if it is to deliver adequate new generation and energy conservation. The action plan should include stable prices that reflect the true cost of power, as determined by an independent regulator. A blended price approach has been recommended. The Task Force recognizes that renewable generation should be a vital part of the future energy supply mix, and calls for immediate implementation of the Renewable Portfolio Standard. tabs., figs

  20. The impact of the Market Power Mitigation Agreement on power prices in Ontario

    2000-01-01

    Market power was defined by the Market Design Committee (MDC) as 'the ability to sustain a significant price increase profitably', although it is generally understood to refer to the 'overwhelming dominance of generating capacity and supply capability of Ontario Power Generation' (OPG), the former generating arm of Ontario Hydro. The MDC sought to address market power within the context of the Ontario Government's White Paper on electricity sector reform, entitled 'Directions for Change'. The solution was the Market Power Mitigation Agreement (MPMA), a negotiated agreement between the MDC and OPG that established market share goals and provided incentives and penalties to meet these goals. Briefly, the major instrument used by the MPMA is the price of electric power sold in the Ontario market to reward, or penalize the actions of OPG in moving towards its market share goals as defined in the MPMA. This paper explains the principal elements of the MPMA and how they are expected to influence the market prices for power in Ontario. The principal elements of the Agreement are price cap and rebate, decontrol targets, and intertie capacity and limits, while the instruments comprise licence conditions, settlement agreements, market rules and ministerial directives. The issue of the impact of the MPMA on the cost of power, and the future prospects of market power after the expiration of the MPMA are also addressed

    Full Text Available The purpose of this study was to examine the capability of hyperspectral narrow wavebands within the 400–900 nm range for distinguishing five cash crops commonly grown in Northeastern Ontario, Canada. Data were collected from ten different fields in the West Nipissing agricultural zone (46°24'N lat., 80°07'W long. and included two of each of the following crop types; soybean (Glycine max, canola (Brassica napus L., wheat (Triticum spp., oat (Avena sativa, and barley (Hordeum vulgare. Stepwise discriminant analysis was used to assess the spectral separability of the various crop types under two scenarios; Scenario 1 involved testing separability of crops based on number of days after planting and Scenario 2 involved testing crop separability at specific dates across the growing season. The results indicate that select hyperspectral bands in the visual and near infrared (NIR regions (400–900 nm can be used to effectively distinguish the five crop species under investigation. These bands, which were used in a variety of combinations include B465, B485, B495, B515, B525, B535, B545, B625, B645, B665, B675, B695, B705, B715, B725, B735, B745, B755, B765, B815, B825, B885, and B895. In addition, although species classification could be achieved at any point during the growing season, the optimal time for satellite image acquisition was determined to be in late July or approximately 75–79 days after planting with the optimal wavebands located in the red-edge, green, and NIR regions of the spectrum.

    Utilization of timed virus acquisition access probes in studies of plum pox virus (PPV) transmission by aphids demonstrated that endemic species transmitted the virus readily from plum, Prunus domestica (L.) Batsch; peach, P. persica (L.); or dwarf flowering almond, P. glandulosa Thunberg., to peach seedlings. The green peach aphid, Myzus persicae (Sulzer), was shown to be the most efficient vector. Acquisition of virus by green peach aphids from infected peach leaves resulted in 18-28% infected peach seedlings, while aphids previously fed on infected leaves of plum transferred virus to 36% of peach seedlings. Although the spirea aphid, Aphis spiraecola (Patch), was a less efficient vector than M. persicae it is perhaps more important for the spread of PPV due to its greater abundance and occurrence earlier in the season when peach trees are thought to be more susceptible to infection. Virus transmission rates varied depending on the virus source and healthy test plant species. In contrast to many previous studies, aphid inoculation of the experimental host Nicotiana benthamiana Domin occurred at a low rate, never exceeding 4%. Acquisition of PPV by M. persicae from infected peach fruit was greatly reduced compared with acquisition from leaves. The results of this research indicate that the Ontario isolate of PPV-D is readily transmissible by aphids to peach and natural spread of the virus needs to be considered in future management or eradication programs. © Her Majesty in Right of Canada, as represented by the Minister of Agriculture and Agri-Food Canada.

    This paper presents results of hydrochemical and isotopic analyses of groundwater (fracture water) and porewater, and physical property and water content measurements of bedrock core at the Chalk River Laboratories (CRL) site in Ontario. Density and water contents were determined and water-loss porosity values were calculated for core samples. Average and standard deviations of density and water-loss porosity of 50 core samples from four boreholes are 2.73 ± 12 g/cc and 1.32 ± 1.24 percent. Respective median values are 2.68 and 0.83 indicating a positive skewness in the distributions. Groundwater samples from four deep boreholes were analyzed for strontium (87Sr/86Sr) and uranium (234U/238U) isotope ratios. Oxygen and hydrogen isotope analyses and selected solute concentrations determined by CRL are included for comparison. Groundwater from borehole CRG-1 in a zone between approximately +60 and −240 m elevation is relatively depleted in δ18O and δ2H perhaps reflecting a slug of water recharged during colder climatic conditions. Porewater was extracted from core samples by centrifugation and analyzed for major dissolved ions and for strontium and uranium isotopes. On average, the extracted water contains 15 times larger concentration of solutes than the groundwater. 234U/238U and correlation of 87Sr/86Sr with Rb/Sr values indicate that the porewater may be substantially older than the groundwater. Results of this study show that the Precambrian gneisses at Chalk River are similar in physical properties and hydrochemical aspects to crystalline rocks being considered for the construction of nuclear waste repositories in other regions.

  4. Preschool Early Literacy Programs in Ontario Public Libraries

    Full Text Available This paper reports on research examining how library staff in 10 Ontario libraries’ preschool literacy programs support three- and four-year-old children’s early literacy and school readiness as well as their parents’ and caregivers’ literacy interactions with their children. Multiple data sources included surveys of 82 parents/caregivers, observations of a sample of 65 of the 198 children at the sessions we visited, and interviews with10 library staff. Observations were analyzed for evidence of children’s development of print motivation, phonological awareness, vocabulary, narrative skills, and print awareness: early literacy skills and knowledge that have been shown to be reliably and significantly correlated with future reading success. Analysis of the observational and interview data showed that the programs have been very successful in fostering children’s readiness to participate in school activities and their motivation to read. Participating children learned new vocabulary, demonstrated an awareness of rhymes and sounds of language, and showed an understanding of books that were read by library staff: all early literacy behaviours that are foundational to later literacy development. The programs have also provided parents/caregivers with new ways to interact with children to engage them with books and with print at home. The development of children’s school readiness skills and parents’ awareness of how to support their children’s literacy are outcomes extending beyond library staff goals for their library programs and should be included in literature advertising the programs. Print awareness is an area of literacy development that library staff could encourage to a greater extent, however. Very few instances of such behaviour were observed, with most of the observations taking place in two of the preschool early literacy programs. Concomitantly, developing children’s print awareness is a recommended topic for

The 75 community health centres (CHCs) in Ontario at the time of the study, which have cared for people with barriers to access to traditional health services in community-governed, interprofessional settings, providing medical, social, and community services since the 1970s. Managers and staff of primary care teams in the CHCs. Scores on the short version of the Team Climate Inventory (with subscales addressing vision, task orientation, support for innovation, and participative safety), the Organizational Justice Scale (with subscales addressing procedural justice and interactional justice), and the Organizational Citizenship Behavior Scale, stratified by staff group (clinical manager, FP, nurse practitioner [NP], registered nurse, medical secretary, social worker, allied health provider, counselor, outreach worker, and administrative assistant). A total of 674 staff members in 58 of 75 (77%) CHCs completed surveys. All staff groups generally reported positive perceptions of team function. The procedural justice subscale showed the greatest variation between groups. Family physicians and NPs rated procedural justice much lower than nurses and administrators did. This study provides a unique view of the perceptions of different groups of staff in a long-standing interprofessional practice model. Future research is needed to understand why FPs and NPs perceive procedural justice more negatively than other team members do, and whether such perceptions affect outcomes such as staff turnover and health outcomes for patients.

  6. Ontario demand forecast from January 2004 to December 2013

    2003-01-01

    This document examined the demand forecast for electricity on the Independent Market Operator (IMO)-controlled grid in Ontario for the period 2004-2013. It serves as an assessment tool to determine whether existing and proposed generation and transmission facilities in the province will be sufficient to meet future electricity needs. Changes in methodology have been made to allow for an hourly peak versus the previously reported 20-minute peak value. Actual data through to the end of October 2002 was used to re-estimate energy demand. Compared to other developed countries, the outlook for the Canadian economy is optimistic. In addition, the economic forecast is better than that which formed the basis of the last ten-year forecast. Energy demand in the median growth scenario is increasing at an annual rate of 1.1 per cent rather than 0.9 per cent for the forecasted period of 2003-2012. The combination of a higher growth rate and a higher starting point results in a 2010 forecast of 168 TWh. It is expected that peak demand will grow faster than in the previous forecast. Summer peak demand averaging an annual growth of 1.3 per cent is forecasted for the period 2003-2012, with winter peak demand averaging a growth of 0.8 per cent. Under normal weather conditions, the electricity system is expected to peak in the summer of 2005 due to the continued demand for cooling load. However, under an extreme weather scenario, the system is already summer peaking. The improved economic outlook and higher starting point resulted in a higher forecast for energy. The electricity system is expected to winter peak during the first years of the forecasted period. The heating load is not expected to experience rapid growth in the next few years. 15 tabs., 14 figs

    2005-01-01

    Evaluation of the potential environmental risk posed by metals depends to a great extent on modeling the fate and mobility of metals with soil-solution partitioning coefficients (K d ). However, the effect of biological cycling on metal partitioning is rarely considered in standard risk assessments. We determined soil-solution partitioning coefficients for 5 metals (Cd, Zn, Pb, Co and Ni) at 46 forested sites that border the Precambrian Shield in central Ontario, where soil pH aq varied from 3.9 to 8.1. Foliage from the dominant tree species and forest floor samples were also collected from each site to compare their metal levels with K d predictions. Analogous to other studies, log K d values for all metals were predicted by empirical linear regression with soil pH (r 2 = 0.66-0.72), demonstrating that metal partitioning between soil and soil solution can be reliably predicted for relatively unpolluted forest mineral soils by soil pH. In contrast, whereas the so-called bioavailable water-soluble metal fraction could be predicted from soil pH, metal concentrations in foliage and the forest floor at each site were not consistently related to pH. Risk assessment of metals should take into account the role of biota in metal cycling and partitioning in forests, particularly if metal bio-accumulation and chronic toxicity in the food chain, rather than metal mobility in soils, are of primary concern. - Metal cycling by plants should be considered in risk assessment studies

    Full Text Available The Ontario Ministry of Education has declared a commitment to Indigenous student success and has advanced a policy framework that articulates inclusion of Indigenous content in schooling curriculum (Ontario Ministry of Education, 2007. What are the perceptions among educators and parents regarding the implementation of policy directives, and what is seen to encourage or limit meaningful implementation? To answer these questions, this article draws on interviews with 100 Indigenous (mainly Haudenosaunee, Anishinaabe, and Métis and non-Indigenous parents and educators from Ontario Canada. Policy directives are seen to benefit Indigenous and non-Indigenous students. Interviews also reveal challenges to implementing Indigenous curricular policy, such as unawareness and intimidation among non-Indigenous educators regarding how to teach material. Policy implications are considered.

    Full Text Available Adolescent literacy has emerged via the high-stakesstandardized test known as the Ontario Secondary School Literacy Test (OSSLTas a critical area of debate and study. Research has indicated a directconnection between literacy and identity, and that student literacy practicesdiffer from traditional measures of literacy located in school curriculum andevaluated via standardized tests such as the OSSLT. Outcomes such as limitedachievement, difficulties with literacy and the development of literacy skills,and subsequent below standard scorescan diminish student self-concept, lower self-esteem, and impede self-efficacy.This ethnographic case study illuminated the impact of OSSLT and subsequentmandatory enrolment in the Ontario Secondary School Literacy Course usingsemi-structured interviews involving high-school students from a northernOntario secondary school. Previous related research outcomes, whichdemonstrated a connection between standardized test scores and self-concept,were realized via participants’ understanding and perception of literacy, andthrough mitigating factors impacting literacy engagement and achievement.

    The main focus of this conference was on the current changes within Ontario's electricity industry and what can be learned from the experience of other jurisdictions. Opinions regarding the switch to open competition in Ontario on May 1, 2002 have been extremely varied. It was noted that open competition generally brings down electricity prices and is beneficial in introducing innovations. Opponents of competition are quick to point out that both California and Alberta have experienced the opposite with open markets. The presentations described the factors that contributed to the creation of an open electricity market in Ontario with reference to the unsustainable electricity rates of the 1990s. Participants at the conference also expressed their views regarding future electricity prices, and presented suggestions of how power transmission, distribution and generation can be optimized while protecting the consumer. A total of 18 papers were presented at the conference, of which 4 were indexed separately for inclusion in the database. refs., tabs., figs

    International Nuclear Information System (INIS)

    Fraser, P.

    2003-01-01

    This document presents the power distribution system of Ontario (Canada) and the crisis that followed the opening of the electricity market on May 1, 2002 in Ontario. The author explains the process of reforms of the power market, the re-structuration of Ontario Hydro company and the occurrence of new energy companies (73 new retailers), the launching of a wholesale market, the reasons of the crisis (25% average rise of electricity prices) and the lessons to be learned from. In front of this situation, a freezing of electricity prices to their level prior to May 2002 and a reimbursement of the difference paid by consumers since May 2002 have been decided by the government up to 2006.

    To assess the efficacy and safety of topical Matricaria chamomilla (Chamomile) oil in patients with knee osteoarthritis. Patients were randomized and treated with topical chamomile oil, diclofenac or placebo, 3 times/day for 3 weeks. They were allowed to use acetaminophen as analgesic. The patients were asked about their total acetaminophen use. Moreover, they were assessed in the terms of pain, physical function and stiffness by using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire at the enrolling and weekly. Chamomile oil significantly reduced the patients' need for acetaminophen (P = 0.001) compared with diclofenac and placebo. However, there were no significant differences in WOMAC questionnaire domains. The patients did not report any adverse events by using chamomile oil. Chamomile oil decreased the analgesic demand of patients with knee osteoarthritis. In addition, it may show some beneficial effects on physical function, and stiffness of the patients.

  18. Setting the price for PV for the Advanced Renewable Tariffs program in Ontario

    International Nuclear Information System (INIS)

    McMonagle, R.

    2005-01-01

    Key considerations for the pricing of photovoltaic (PV) energy in an advanced renewable tariff (ART) program in Ontario were presented. This paper addressed solar industry fears concerning a financing mechanism for on-site solar generation in Ontario and its potential to fail if markets are not sufficiently prepared in advance. The mechanism could result in the creation of an unsustainable demand for solar products. It was suggested that in addition to building capacities in the industry, training and public education are important issues that the first phase of an ART's program must address. A 5 year pilot program was recommended in order to build industry infrastructure and capacity, before moving to rates based on the model developed by the Ontario Sustainable Energy Association. An initial price of 0.42 kWh was recommended to stimulate early adopters and to build capacity. It was noted that PV supplied power coincides with peak demand, and that its ART rate should reflect this premium cost value. Ontario ratepayers are already paying millions of dollars for electricity at rates higher than $0.42 per kWh. It was estimated that the average cost of the ART program for PV in the introductory stage would cost ratepayers under $10 million per year. While there have been no Canadian studies done on the value of PV's benefits to the power grid, Californian studies have indicated that benefits for Ontario should range between $0.20-$0.38 CAN per kWh. It was concluded that the price for PV in Ontario's ARTs program needs to be set at a high enough rate to stimulate the sustainable growth of the industry in the province. 10 refs., 3 tabs., 3 figs

    Full Text Available Abstract Background Given the proliferation and the growing complexity of performance measurement initiatives in many health systems, the Netherlands and Ontario, Canada expressed interests in cross-national comparisons in an effort to promote knowledge transfer and best practise. To support this cross-national learning, a study was undertaken to compare health system performance approaches in The Netherlands with Ontario, Canada. Methods We explored the performance assessment framework and system of each constituency, the embeddedness of performance data in management and policy processes, and the interrelationships between the frameworks. Methods used included analysing governmental strategic planning and policy documents, literature and internet searches, comparative descriptive tables, and schematics. Data collection and analysis took place in Ontario and The Netherlands. A workshop to validate and discuss the findings was conducted in Toronto, adding important insights to the study. Results Both Ontario and The Netherlands conceive health system performance within supportive frameworks. However they differ in their assessment approaches. Ontario's Scorecard links performance measurement with strategy, aimed at health system integration. The Dutch Health Care Performance Report (Zorgbalans does not explicitly link performance with strategy, and focuses on the technical quality of healthcare by measuring dimensions of quality, access, and cost against healthcare needs. A backbone 'five diamond' framework maps both frameworks and articulates the interrelations and overlap between their goals, themes, dimensions and indicators. The workshop yielded more contextual insights and further validated the comparative values of each constituency's performance assessment system. Conclusion To compare the health system performance approaches between The Netherlands and Ontario, Canada, several important conceptual and contextual issues must be addressed

    Ontario Hydro is the principal supplier of electricity to the Province of Ontario. It serves 3.6 million customers, with an inservice capacity of 28,200 MW. Ontario Hydro has seven fossil, five nuclear, and four hydraulic stations in the Great Lakes Basin and surrounding watershed. In addition, there are another 60 inland hydraulic stations and numerous dams. As the largest single user of raw water from the Great Lakes Basin, Ontario Hydro recognized the need to control zebra mussels early in 1989. At that time, very little was known in North America about the zebra mussel life cycle and potential impact. European utilities were consulted, but as we now know, zebra mussels are not perceived to be a problem in Europe at this time. To satisfy the immediate need for control, chlorination was identified as the most effective interim measure to prevent the fouling of systems which draw water from the aquatic environment. Due to the current regulatory environment, this solution is considered short term and Ontario Hydro was compelled to initiate a comprehensive research effort aimed at providing alternative methods of control. Most of the research effort during 1990, was methods of control. Most of the research effort during 1990, was directed towards this goal. Many alternative control measures, both chemical and nonchemical were considered. Also considered were the potential effects of the control measures and zebra mussels on station operations. A multidisciplinary team involving aquatic biologists, chemists, corrosion specialists, and civil and mechanical engineers from the various departments of Ontario Hydro was asked to address the problem. Some of the research also involved collaborative studies with universities, US utilities, American Water Works Association, and Canadian industries. Following is a summary of the research effort in 1990, and a preview of the research underway in 1991

    Renewable energy received a boost in Ontario, Canada with the Green Energy and Green Economy Act (GEGEA), ushering in a new Feed-in-Tariff (FIT) program modelled on programs from Germany, Spain, Denmark and other jurisdictions. Information about lessons learned elsewhere has clearly benefited the Ontario experience. Part of the Ontario program included streamlining the impact assessment process to facilitate the swift development of provincial renewable energy capacities. In this context, the GEGEA has been remarkably successful, generating renewable energy sector capacities, resources, projects and their spin-off benefits in Ontario, along with more sustainable electricity system. Environmentalists along with industry continue to laud the benefits of renewable energy and the GEGEA, and with good reason. Renewable energy generation in Ontario has grown from to 2 per cent in 2012 and is expected to reach 10 per cent in 2013. (orig.)

    Prior studies have documented inferior health outcomes in vulnerable populations, including racial minorities and those with disadvantaged socioeconomic status. The impact of immigration on cancer-related outcomes is less clear. Administrative databases were linked to create a cohort of incident cancer cases (colorectal, lung, prostate, head and neck, breast, and hematologic malignancies) from 2000 to 2012 in Ontario, Canada. Cancer patients who immigrated to Canada (from 1985 onward) were compared with those who were Canadian born (or immigrated before 1985). Patients were followed from diagnosis until death (cancer-specific or all-cause). Cox proportional hazards models were estimated to determine the impact of immigration on mortality after adjusting for explanatory variables. Additional adjusted models studied the relationship of time since immigration and cancer-specific and overall mortality. From 2000 to 2012, 11,485 cancer cases were diagnosed in recent immigrants (0 to 10 years in Canada), 17,844 cases in nonrecent immigrants (11 to 25 years), and 416,118 cases in nonimmigrants. After adjustment, the hazard of mortality was lower for recent immigrants (hazard ratio [HR], 0.843; 95% CI, 0.814 to 0.873) and nonrecent immigrants (HR, 0.902; 95% CI, 0.876 to 0.928) compared with nonimmigrants. Cancer-specific mortality was also lower for recent immigrants (HR, 0.857; 95% CI, 0.823 to 0.893) and nonrecent immigrants (HR, 0.907; 95% CI, 0.875 to 0.94). Among immigrants, each year from the original landing was associated with increased mortality (HR, 1.004; 95% CI, 1.000 to 1.009) and a trend to increased cancer-specific mortality (HR, 1.005; 95% CI, 0.999 to 1.010). Immigrants demonstrate a healthy immigrant effect, with lower cancer-specific mortality compared with Canadian-born individuals. This benefit seems to diminish over time, as the survival of immigrants from common cancers potentially converges with the Canadian norm.

    External biosecurity protocols, aimed at preventing the introduction of new pathogens to the farm environment, are becoming increasingly important in the swine industry. Although assessments at the individual farm level occur regularly, efforts to cluster swine herds into meaningful biosecurity groups and to summarize this information at the regional level are relatively infrequent. The objectives of this study were: (i) to summarize external biosecurity practices on sow farms in southern Ontario; (ii) to cluster these farms into discrete biosecurity groups and to describe their characteristics, the variables of importance in differentiating between these groups, and their geographic distribution; and (iii) to identify significant predictors of biosecurity group membership. Data were collected using the Production Animal Disease Risk Assessment Program's Survey for the Breeding Herd. A subset of variables pertaining to external biosecurity practices was selected for two-step cluster analysis, which resulted in 3 discrete biosecurity groups. These groups were named by the authors as: (i) high biosecurity herds that were open with respect to replacement animals, (ii) high biosecurity herds that were closed with respect to replacement animals, and (iii) low biosecurity herds. Variables pertaining to trucking practices and the source of replacement animals were the most important in differentiating between these groups. Multinomial logistic regression provided insight into which demographic and neighborhood variables serve as significant predictors of biosecurity group membership (pbiosecurity group that was open with respect to replacement animals, relative to the low biosecurity group, increased 1.001 times for each additional sow (p=0.001). The odds of belonging to the high biosecurity group that was open with respect to replacement animals, relative to the low biosecurity group, were 6.5 times greater for farms that produced genetic animals than for farms that

    Oliver, F.

    2004-02-01

    This paper presents the position of the Canadian Energy Efficiency Alliance (CEEA) on certain aspects of governance requiring demand side management for electricity reform. It also describes the components that should be included in Ontario's DSM framework. In November 2003, the Ontario government announced legislation to ensure a fair and predictable approach to electricity pricing and energy conservation. An interim pricing structure raises the existing price cap for electricity. On March 1, 2005, local electricity distribution companies will be able to achieve their full commercial return conditional on their reinvestment of one year's worth of monies in conservation and demand management initiatives. The CEEA supports the government's commitment to DSM. The CEEA is also in agreement with a report released by Ontario's Energy Minister in January 2004 which reveals that all reforms for the electricity sector would be focused on: energy conservation; reliability, diversity, and affordability; effective consumer protection; new investment in conservation, generation and transmission; and, clean air by eliminating coal fired generation and replacing it with cleaner sources of energy. This report outlined some of the barriers to efficient energy use and the components that would ensure effective and efficient delivery of DSM programs. It was emphasized that energy prices should reflect true costs in order to address market barriers to efficient energy use

    2010-06-15

    Canada has been blessed with immense energy resources; however, their distribution is not uniform. One such example is crude oil, which is found primarily in western Canada. Eastern Canada, consisting of the six eastern-most provinces (Newfoundland and Labrador, New Brunswick, Nova Scotia, Ontario, Prince Edward Island, and Quebec), produce limited quantities of crude oil, most of which is exported to the United States. Ideally, western Canadian crude oil would meet the demands of eastern Canada; however, the North American Free Trade Agreement (NAFTA) and the absence of oil pipelines means that eastern Canada increasingly relies on supplies of crude oil from a small number of oil exporting countries, many with declining production. This paper examines crude oil production, supply, and its refining in eastern Canada. It shows that crude production in the region has reached its peak and that increasing global competition for crude oil will affect energy security in eastern Canada, either through price increases or supply shortages, or both.

    1999-01-01

    A field study was conducted in the lower Great Lakes to assess changes in spatial distribution and population structure of dreissenid mussel populations. More specifically, the westward range expansion of quagga mussel into western Lake Erie and toward Lake Huron was investigated and the shell size, density, and biomass of zebra and quagga mussel with depth in southern Lake Ontario in 1992 and 1995 were compared. In Lake Erie, quagga mussel dominated the dreissenid community in the eastern basin and zebra mussel dominated in the western basin. In southern Lake Ontario, an east to west gradient was observed with the quagga mussel dominant at western sites and zebra mussel dominant at eastern locations. Mean shell size of quagga mussel was generally larger than that of zebra mussel except in western Lake Erie and one site in eastern Lake Erie. Although mean shell size and our index of numbers and biomass of both dreissenid species increased sharply in southern Lake Ontario between 1992 and 1995, the increase in density and biomass was much greater for quagga mussels over the 3-year period. In 1995, zebra mussels were most abundant at 15 to 25 m whereas the highest numbers and biomass of quagga mussel were at 35 to 45 m. The quagga mussel is now the most abundant dreissenid in areas of southern Lake Ontario where the zebra mussel was once the most abundant dreissenid; this trend parallels that observed for dreissenid populations in the Dneiper River basin in the Ukraine.

    The authors document the status of Lake Ontario's open-water fish community in 1972, near the beginning of an era of massive fish stocking and when phosphorus levels in the lake from anthropogenic inputs, were near their peak. They then describe changes that occurred in the fish community in 1978-98. This was a period when large numbers of young salmonid piscivores were released annually, sea lamprey control continued to improve, and phosphorus levels were declining due to successful nutrient abatement programs. Coincident with the above, the lower food web was changed by the addition of new exotic invertebrates, the zooplankter Bythotrephes cederstroemi and particularly the zebra mussel, Dreissena polymorpha, and quagga mussel, D. bugensis. The picture of the fish community structure is drawn from records of catches in bottom trawls and gill nets during surveys of southern Lake Ontario conducted the the U.S. Geological Survey (USGS) and the New York Department of Environmental Conservation (NYDEC), from records of fish stocked in Lake Ontario by the NYDEC, and from a creel census of boat anglers returning to southern Lake Ontario ports conducted by the NYDEC.

    2001-01-01

    This power point presentation discussed the meaning of market power and how Ontario Power Generation's market power is one of the most contentious market implementation issues in the deregulation debate. Market power was described as being the ability to profitably maintain prices above competitive levels for a significant period of time. The presentation referred to the key elements of the market power mitigation framework (MPMF) of Ontario and how it strikes a balance between the three major objectives of creating a competitive marketplace, to pay down the stranded debt, and to ensure viable power generation in the province. It was concluded that there will be a viable competitive market in Ontario in the near future, but a pragmatic, fact-based view of the market is needed to allow market forces to work. It was emphasized that markets by nature are unpredictable and volatility does not necessarily means that the market is not working. The author stated that Ontario Power Generation recognized that it is important to coordinate roles and responsibilities to minimize duplication and reduce confusion. tags., figs

  10. The Market Surveillance Panel in Ontario's electricity market : monitoring, investigating and reporting : backgrounder

    International Nuclear Information System (INIS)

    2002-04-01

    The Market Surveillance Panel (MSP) is an independent body appointed by and accountable to the Independent Directors of Ontario's Independent Electricity Market Operator (IMO). The MSP is fundamental to the development of competitive electricity markets because it is instrumental in monitoring the activities of the Ontario electricity market open to competition as of May 2002. The role of the MSP is to monitor, investigate and report on the behaviour of markets that are administered by the IMO. It is instrumental in promoting the benefits of competition to Ontario energy users. While the MSP is not a regulator, it is empowered to make recommendations to the IMO, the Ontario Energy Board and the Competition Bureau. The role of the MSP is to identify, understand and explain market outcomes that are anomalous, with particular focus on real-time energy price movements and market outcomes, gaming and the exercise of local market power. The report notes that energy prices are expected to fluctuate more in a competitive market than in a regulated market, and that price movements are actually healthy. However, the role of the MSP is to assess energy prices by asking important questions regarding the signaling role of prices, and to ensure that the changes in prices are not a result of abuse of market power. The MSP will also focus on the impediments to effective competition and on recommending actions to mitigate them. 5 refs

    2013-04-01

    The Council of Ontario University Programs in Nursing offers a nine-university, consortium-based primary health care nurse practitioner education program and on-line continuing education courses for primary health care nurse practitioners. Our study sought to determine the continuing education needs of primary health care nurse practitioners across Ontario, how best to meet these needs, and the barriers they face in completing continuing education. Surveys were completed by 83 (40%) of 209 learners who had participated in continuing education offered by the Council of Ontario University Programs in Nursing between 2004 and 2007. While 83% (n=50) of nurse practitioners surveyed indicated that continuing education was extremely important to them, they also identified barriers to engaging in continuing education offerings including; time intensity of the courses, difficulty taking time off work, family obligations, finances and fatigue. The most common reason for withdrawal from a continuing education offering was the difficulty of balancing work and study demands. Continuing education opportunities are important to Ontario primary health care nurse practitioners, and on-line continuing education offerings have been well received, but in order to be taken up by their target audience they must be relevant, readily accessible, flexible, affordable and offered over brief, intense periods of time using technology that is easy to use and Internet sites that are easily navigated.

  18. Physician prescribing of opioid agonist treatments in provincial correctional facilities in Ontario, Canada: A survey.

    Directory of Open Access Journals (Sweden)

    Fiona G Kouyoumdjian

    Full Text Available Substance use and substance use disorders are common in people who experience detention or incarceration in Canada, and opioid agonist treatment (OAT may reduce the harms associated with substance use disorders. We aimed to define current physician practice in provincial correctional facilities in Ontario with respect to prescribing OAT and to identify potential barriers and facilitators to prescribing OAT.We invited all physicians practicing in the 26 provincial correctional facilities for adults in Ontario to participate in an online survey.Twenty-seven physicians participated, with representation from most correctional facilities in Ontario. Of participating physicians, 52% reported prescribing methadone and 48% reported prescribing buprenorphine/naloxone to patients in provincial correctional facilities. Nineteen percent of participants reported initiating methadone treatment and 11% reported initiating buprenorphine/naloxone for patients in custody. Participants identified multiple barriers to initiating OAT in provincial correctional facilities including concerns about medication diversion and safety, concerns about initiating treatment in patients who are not currently using opioids, lack of linkage with community-based providers and the Ministry of Community Safety and Correctional Services policy. Identified facilitators to initiating OAT were support from institutional health care staff and administrative staff, adequate resources for program delivery and access to linkage with community-based OAT providers.This study identifies opportunities to improve OAT programs and to improve access to OAT for persons in provincial correctional facilities in Ontario.

  1. Metals and Organohalogen Contaminants in Bald Eagles (Haliaeetus leucocephalus) from Ontario, 1991-2008.

    Science.gov (United States)

    Martin, P A; Hughes, K D; Campbell, G D; Shutt, J L

    2018-02-01

    We examined the degree of exposure of lead (Pb), mercury (Hg), and several organohalogen contaminants and its potential impact on survival of bald eagles in Ontario from 1991 to 2008. Overall, results for 43 dead or dying bald eagles collected in the province indicate that 23% (10/43) of birds died of Pb poisoning and 9% (4/43) died of suspected Hg poisoning. Pb poisoning was diagnosed based on exceedances of toxicity thresholds in liver and kidney and supported by clinical observations, necropsy results, and histology findings when available. Evidence for Hg poisoning in eagles was limited; however, Hg concentrations exceeded the toxicity threshold in kidney. Pb concentrations ranged widely in liver and kidney. Total Hg concentrations were relatively higher in kidney compared with liver and were significantly correlated with selenium (Se) concentrations in both tissues. Concentrations of p,p'-DDE and sum PCBs in livers of 12 bald eagles collected from 2001 to 2004 were likely below concentrations associated with adverse effects. Hepatic concentrations of total polybrominated diphenyl ethers were generally higher in birds collected from southern Ontario compared with northern Ontario. Potential impacts of exposure to these flame retardants and others are not known. Elevated metal exposure appears to influence survivorship and may affect the recovery of bald eagles in the province, particularly in southern Ontario and along the Great Lakes where a disproportionate number of poisoned eagles were collected. Increased efforts are needed to identify sources of exposure and develop measures to reduce metal exposure in this top predator.

  3. A heuristic simulation model of Lake Ontario circulation and mass balance transport

    Science.gov (United States)

    McKenna, J.E.; Chalupnicki, M.A.

    2011-01-01

    The redistribution of suspended organisms and materials by large-scale currents is part of natural ecological processes in large aquatic systems but can contribute to ecosystem disruption when exotic elements are introduced into the system. Toxic compounds and planktonic organisms spend various lengths of time in suspension before settling to the bottom or otherwise being removed. We constructed a simple physical simulation model, including the influence of major tributaries, to qualitatively examine circulation patterns in Lake Ontario. We used a simple mass balance approach to estimate the relative water input to and export from each of 10 depth regime-specific compartments (nearshore vs. offshore) comprising Lake Ontario. Despite its simplicity, our model produced circulation patterns similar to those reported by more complex studies in the literature. A three-gyre pattern, with the classic large counterclockwise central lake circulation, and a simpler two-gyre system were both observed. These qualitative simulations indicate little offshore transport along the south shore, except near the mouths of the Niagara River and Oswego River. Complex flow structure was evident, particularly near the Niagara River mouth and in offshore waters of the eastern basin. Average Lake Ontario residence time is 8 years, but the fastest model pathway indicated potential transport of plankton through the lake in as little as 60 days. This simulation illustrates potential invasion pathways and provides rough estimates of planktonic larval dispersal or chemical transport among nearshore and offshore areas of Lake Ontario. ?? 2011 Taylor & Francis.

  10. Market readiness report : status of preparation for Ontario's competitive retail electricity market

    International Nuclear Information System (INIS)

    2002-01-01

    The Ontario Energy Board (OEB) assumes a leadership role in the electricity sector to ensure the readiness of retail participants in Ontario's competitive electricity market. The Market Readiness Project Team is instrumental in this activity. The team, led by the Independent Electricity Market Operator, provides information and advice regarding the technical readiness of the retail industry, with particular focus on the readiness of distributors to carry out their important functions in a competitive market. This report provides an assessment of the team regarding the industry's technical readiness based on information as of December 14, 2001. The status of retail market readiness was reviewed in terms of the viability of the design of the new competitive market and on the status of Ontario distributors in enabling a competitive market. The workplan for the remaining industry activities needed to achieve market opening were then summarized along with the contingency arrangements for any distributors that are not ready for market opening. Based on several projections, an estimated 88 per cent of Ontario contracts will be served by a distributor starting on a May 1, 2002 market opening. tabs., figs., appendices

  17. Ontario is not ready to face a large-scale nuclear accident

    International Nuclear Information System (INIS)

    2017-07-01

    On paper, in Japan as elsewhere, nuclear emergency plans are based on international standards and all look similar. The counter measures are sheltering, potassium iodate prophylaxis, evacuation and control of foodstuffs. With 18 nuclear reactors to produce electricity and a research reactor, Ontario should be especially well prepared. Moreover, in USA, there are six power plants located at less than 100 km from the Canadian border. Would Ontario do better than Japan in case of a severe nuclear disaster? Ontario is not ready to face a severe nuclear accident and the population surrounding nuclear power stations are at risk. The large number of inhabitants will hamper protective response actions. Consequently, Canadian authorities keep lax protective action levels. Using more stringent levels would mean to extend the protection zone that would include a too large number of persons. Canadian authorities should openly acknowledge that a severe nuclear accident could happen in Ontario like in any other country and trigger a complete reorganisation of emergency preparedness and response (EP and R) to cope with such a possibility. New response plans should be defined with the involvement of stakeholders

    Full Text Available Abstract Background Invasive meningococcal disease (IMD caused by serogroup B is the last major serogroup in Canada to become vaccine-preventable. The anticipated availability of vaccines targeting this serogroup prompted an assessment of the epidemiology of serogroup B disease in Ontario, Canada. Methods We retrieved information on confirmed IMD cases reported to Ontario’s reportable disease database between January 1, 2000 and December 31, 2010 and probabilistically-linked these cases to Public Health Ontario Laboratory records. Rates were calculated with denominator data obtained from Statistics Canada. We calculated a crude number needed to vaccinate using the inverse of the infant ( Results A total of 259 serogroup B IMD cases were identified in Ontario over the 11-year period. Serogroup B was the most common cause of IMD. Incidence ranged from 0.11 to 0.27/100,000/year, and fluctuated over time. Cases ranged in age from 13 days to 101 years; 21.4% occurred in infants, of which 72.7% were Conclusions Although rare, the proportion of IMD caused by serogroup B has increased and currently causes most IMD in Ontario, with infants having the highest risk of disease. Although serogroup B meningococcal vaccines are highly anticipated, our findings suggest that decisions regarding publicly funding serogroup B meningococcal vaccines will be difficult and may not be based on disease burden alone.

    2011-06-01

    We documented the extent of point-of-sale (POS) lottery promotions in Ontario, Canada and the relationship between lottery promotions and store and city characteristics. This is the first quantitative study of POS lottery promotions. A total of 366 stores-independent and chain convenience stores, gas stations and grocery stores-were visited across 20 cities in Ontario. Data collectors unobtrusively observed the type of lottery promotions in each store and completed a data collection checklist. A lottery promotion index was created and hierarchical linear modeling (HLM) was conducted to examine the relationship between extent of lottery promotions and independent variables such as neighbourhood socioeconomic status and city prevalence of lottery ticket purchasing. POS lottery promotions were widespread across Ontario, with the highest level of promotion found in independent convenience stores. In the multivariable HLM model, none of the remaining independent variables remained statistically significant, except for store type. Lottery promotions are extensive at the POS in Ontario. These findings can help initiate discussions around the appropriateness and possible future regulation of this form of advertising.

  12. Legal requirements for human-health based appeals of wind energy projects in ontario.

    Science.gov (United States)

    Engel, Albert M

    2014-01-01

    In 2009, the government of the province of Ontario, Canada passed new legislation to promote the development of renewable energy facilities, including wind energy facilities in the province. Throughout the legislative process, concerns were raised with respect to the effect of wind energy facilities on human health. Ultimately, the government established setbacks and sound level limits for wind energy facilities and provided Ontario residents with the right to appeal the approval of a wind energy facility on the ground that engaging in the facility in accordance with its approval will cause serious harm to human health. The first approval of a wind facility under the new legislation was issued in 2010 and since then, Ontario's Environmental Review Tribunal as well as Ontario's courts has been considering evidence proffered by appellants seeking revocation of approvals on the basis of serious harm to human health. To date, the evidence has been insufficient to support the revocation of a wind facility approval. This article reviews the legal basis for the dismissal of human-health based appeals.

  15. Mo & Fe Influences on Nitrate Assimilation in Lake Ontario and the St Lawrence River

    Lake Ontario has undergone a steady increase in nitrate since the early 1970s, a phenomenon also occurring in other large lakes. Possible causes of this increase include rising urban and agricultural runoff, atmospheric deposition, less demand for N due to effective point source P control, and trace metal-N co-limitation as observed in Lake Erie. Despite the abundance of nitrate in Lake Ontario, heterocystous cyanobacteria have been detected here setting up the paradoxical situation wherein some cyanobacteria are investing in the more costly diazotrophy whilst surrounded by a form of N that requires less energy and metal quota to assimilate. Mo and Fe are involved in reductive nitrate assimilation making it possible that reductive nitrate assimilation in Lake Ontario is limited in phytoplankton by low trace metal bioavailability. To test this hypothesis, 1-d enrcihment experiments were conducted using trace metal clean techniques in June 2013 at two coastal sites in Lake Ontario, and 4-d enrichment experiments were conducted in July 2013 on main channel waters of the St. Lawrence River, the outflow of Lake Ontario. Water was sampled from the metalimnion of Lake Ontario and from surface water of the main channel of the river. Water was enriched with the the following treatments in triplicate: control, 100 nM KH2PO4, 50 nM FeCl3, 50 nM Na2MoO4, and a mix of P, Fe & Mo. Experiments in the river showed significant effects due to P (increase in Chl-a, NO3 and SiO2 drawdown, changes in phytoplankton community, increase in photosynthetic efficiency [Fv/Fm]) but less impact of trace metals relative to control, presumably due to greater ambient trace metal bioavailability. As measured using FluoroProbe, the phytoplankton community changed very little (over 1 d) in lake waters; there was no significant change in total chl-a. However, as in the river, Fv/Fm revealed significant metal and P effects with the P, Fe & Mo mix being significantly greater than control (Fig. 1; we

  16. Double-crested Cormorant studies at Little Galloo Island, Lake Ontario in 2013: Diet composition, fish consumption and the efficacy of management activities in reducing fish predation

    Johnson, James H.; McCullough, Russ D.; Mazzocchi, Irene

    2014-01-01

    For almost two decades Little Galloo Island (LGI) has supported a large colony of Double-crested Cormorants (Phalacrocorax auritus) in the eastern basin of Lake Ontario. Cormorant nest counts on the island since the early 1990's have averaged 4,297 per year. However, less than 2,000 pairs have nested on the island in three of the past five years. The highest count was reached in 1996 with 8,410 nesting pairs on the island. Johnson et al. (2013) estimated that cormorants from LGI alone have consumed 504 million fish since 1992. The proliferation of cormorants in the eastern basin of Lake Ontario coincided with declines in two important recreational fish species, smallmouth bass (Micropterus dolemieu) and yellow perch (Perca falvescens). Lantry et al. (2002) and Burnett et al. (2002) provide convincing evidence linking cormorant population increases to declining eastern basin smallmouth bass and yellow perch stocks. Decline of these fish stocks was evident only in the eastern basin, suggesting a localized problem, which is consistent with the halo effect where large piscivorous waterbird colonies may deplete local fish stocks (Birt et al. 1987). The year 2013 marked the twenty second consecutive year of study of the food habits and fish consumption of LGI cormorants and the fifteenth consecutive year evaluating the efficacy of management activities to control the reproductive success of cormorants nesting at LGI. The program consists mainly of spraying cormorant eggs with food grade vegetable oil as well as the culling of adult and immature birds. This paper reports the findings of work carried out in 2013 at LGI.

    A study initiated to find a non-toxic environmentally friendly fluid suitable for use in hydraulic systems, such as in marine and food processing operations, has resulted in a fish-oil-based fluid that appears promising. This paper describes the fluid testing and laboratory and field system tests used to evaluate the fish oil with additive packages. The fish oil with non-toxic additives was endurance tested for durability in complete hydraulic systems in the laboratory and introduced into a commercial system. The results indicate that the oil functioned very well in the systems and the components were compatible with the oil, giving no degradation, wear or performance problems. (author)

    2003-01-01

    The authors described the mysterious oil spill which occurred in the Detroit River in 2002. Advanced chemical fingerprinting and data interpretation techniques were conducted on spill samples collected by Environment Canada, Ontario Region, to determine the chemical composition of the oil and find out where it came from. The objective was to gather information concerning the nature, type, and components of the spill samples. The authors checked if the samples were identical to determine if they originated from the same source. They used a tiered analytical approach which facilitates the detailed compositional analysis by gas chromatograph-mass spectrometer (GC-MS) and GC-flame ionization detection (FID). A wide range of diagnostic ratios of source-specific marker compounds for interpreting chemical data was determined and analyzed. The results proved that: (1) the spill samples were largely composed of lube oil mixed with a smaller portion of diesel fuel, (2) sample number 3 collected from N. Boblo Island was more weathered than samples 1 and 2, (3) the oil in three samples was the same and originated from the same source, as shown by fingerprinting results, (4) most PAH compounds were from the diesel portion in the spill samples, and the biomarker compounds were mostly from the lube oil, (5) the diesel in the samples had been weathered and degraded, and the lube oil in the spill samples was waste lube oil, and (6) input of pyrogenic PAHs to the spill samples was clearly proven. The spill likely came from a place where both combustion and motor lubrication processes occur. 46 refs., 4 tabs., 6 figs

  1. Ontario emissions trading code : emission reduction credit creation, recording and transfer rules, rules for renewable energy projects and conservation projects, and rules for the operation of the Ontario Emissions Trading Registry

    International Nuclear Information System (INIS)

    2001-12-01

    Emissions trading has been an integral part of Ontario's air quality strategy since December 31, 2001. Ontario has adopted the 'cap, credit and trade' type of emissions trading system, a hybrid that takes the best features of pure 'cap-and-trade' and 'baseline-and-credit' type systems. It covers nitric oxide and sulphur dioxide. The Ontario Emissions Trading Code supplements Ontario Regulation 397/01 and sets out rules for renewable energy projects and conservation projects for which applications for emission allowances can be made. This Code describes the rules for the creation and transfer of emission reduction credits (ERCs). It also explains the rules for the operation of the registry that has been established to provide information to the public about the emissions trading program and records decisions about credit creation and credit and allowance retirement. 3 tabs

    Full Text Available Objective: The main purpose of this study was to evaluate the effects of virgin olive oil phonophoresis on female athletes' anterior knee pain (AKP. Materials and Methods: A double blinded randomized clinical trial was conducted. Ninety-three female athletes suffering from AKP voluntarily participated in this study. Patients were randomly assigned into olive oil (n=31, piroxicam (n=31 or base gel phonophoresis (n=31 groups. At the baseline visit, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC questionnaire was filled by subjects who were then treated with olive oil, piroxicam or pure phonophoresis for 12 sessions. After 6 and 12 sessions of physiotherapy, subjects filled the questionnaire again. Main outcomes were significant improvement in pain, stiffness, physical function, and total WOMAC scores. Results: Although, there was a significant reduction in symptoms of AKP at the end of the therapy in all groups (p< 0.05, but in olive oil group, this improvement was seen after 6 sessions of treatment (p< 0.001. A significant difference between olive oil group and piroxicam and/or phonophoresis group was observed after 6 sessions of therapy (p< 0.05. Conclusion: It could be proposed that phonophoresis with virgin olive oil is as effective as piroxicam gel on lowering WOMAC scores of AKP in female athletes and also has several beneficial properties including faster effect and shorter duration of therapy. The exact mechanism of beneficial action of virgin olive oil on AKP is not clear and requires further studies.

    Full Text Available Major depression affects up to half of people living with HIV. However, among HIV-positive patients, depression goes unrecognized 60-70% of the time in non-psychiatric settings. We sought to evaluate three screening instruments and their short forms to facilitate the recognition of current depression in HIV-positive patients attending HIV specialty care clinics in Ontario.A multi-centre validation study was conducted in Ontario to examine the validity and accuracy of three instruments (the Center for Epidemiologic Depression Scale [CESD20], the Kessler Psychological Distress Scale [K10], and the Patient Health Questionnaire depression scale [PHQ9] and their short forms (CESD10, K6, and PHQ2 in diagnosing current major depression among 190 HIV-positive patients in Ontario. Results from the three instruments and their short forms were compared to results from the gold standard measured by Mini International Neuropsychiatric Interview (the "M.I.N.I.".Overall, the three instruments identified depression with excellent accuracy and validity (area under the curve [AUC]>0.9 and good reliability (Kappa statistics: 0.71-0.79; Cronbach's alpha: 0.87-0.93. We did not find that the AUCs differed in instrument pairs (p-value>0.09, or between the instruments and their short forms (p-value>0.3. Except for the PHQ2, the instruments showed good-to-excellent sensitivity (0.86-1.0 and specificity (0.81-0.87, excellent negative predictive value (>0.90, and moderate positive predictive value (0.49-0.58 at their optimal cut-points.Among people in HIV care in Ontario, Canada, the three instruments and their short forms performed equally well and accurately. When further in-depth assessments become available, shorter instruments might find greater clinical acceptance. This could lead to clinical benefits in fast-paced speciality HIV care settings and better management of depression in HIV-positive patients.

    2004-02-01

    This report presents the views of the Ontario Division of the Canadian Union of Public Employees (CUPE) on the Ontario Energy Board's consideration to promote further efficiencies in the power distribution sector. CUPE claims that efficiencies aimed at lowering costs through amalgamations often lead to increased costs, degradation in services and decreased reliability of power distribution. CUPE also argues that the main concerns of Ontario ratepayers is reliability and the threat of increased prices. CUPE recommends that the Ontario Energy Board hold open consultations with ratepayers, who are in fact shareholders in their local utilities. This report reviewed the current regulatory regime known as Performance Based Regulation and its effect on local distribution utilities. It also reviewed the impacts of mergers, amalgamations, acquisitions and divestitures (MAAD), with particular reference to rates, privatization of utility services, service degradation and job losses

    Full Text Available Rural patients with opioid use disorder (OUD face a variety of barriers when accessing opioid agonist therapy (OAT and psychiatric services, due to the limited supply of physicians and the vast geographic area. The telemedicine allows for contact between patients and their physician—regardless of physical distance. Objective. We characterize the usage of telemedicine to deliver psychiatric services to patients with OUD in Ontario, as well as traits of treatment-seeking patients with opioid dependence and concurrent psychiatric disorders. Methodology. A retrospective cohort study was conducted using an administrative database for patients who received psychiatric services via telemedicine between 2008 and 2014 and who also had OUD. Results. We identified 9,077 patients with concurrent opioid use and other mental health disorders who had received psychiatric services via telemedicine from 2008 to 2014; 7,109 (78.3% patients lived in Southern Ontario and 1,968 (21.7% in Northern Ontario. Telemedicine was used more frequently to provide mental health services to patients residing in Northern Ontario than Southern Ontario. Conclusion. Telemedicine is increasingly being utilized throughout Ontario for delivering mental health treatment. There is an opportunity to increase access to psychiatric services for patients with opioid dependence and concurrent psychiatric disorders through the use of the telemedicine.

    2001-01-01

    One of the responsibilities of Ontario's Independent Electricity Market Operator (IMO) is to make sure that existing and proposed generation and transmission facilities can meet the province's energy needs. This report presents an assessment of the adequacy of resources and transmission for Ontario's electricity system for the 18 month period from October 2001 to March 2003. It is also meant to advise the Ontario Energy Board of any adverse conditions that might be avoided through adjustment or coordination of maintenance plans for generation and transmission equipment. The assessment is based on forecasts of electricity demand, available supply and capability of the existing transmission system. Outage plans of generators and transmitters were based on information as of August 3, 2001. An 18 month forecast of electricity demand for Ontario was presented along with the resources and transmission systems that are expected to be available during the study period. The overall assessment is that there will be sufficient resources and transmission available in Ontario to supply the predicted energy demand and to meet the specified reserve margins under the forecasted conditions. The report included graphs which depicted how the weekly peak Ontario demand plus a weekly reserve requirement can be met for each week of the Outlook timeframe. The resource adequacy assessment takes into account all types of weather conditions on a probabilistic basis. 16 tabs., 8 figs

    2017-01-01

    This paper examines inter-bureaucracy tension, negotiation, and resolution in the case of the oversight of beverage room sanitation in Ontario in the 1930s and 1940s. Both the Liquor Control Board of Ontario (LCBO) and various public health authorities claimed authority over the health status of public drinking spaces. But the LCBO had legislative priority. The ensuing debates regarding health and cleanliness linked issues of beverage room glass sanitation to a biopolitical approach to public drinking. Developing a more scientifically sophisticated approach to beverage glass cleaning required a balancing of administrative priorities. Perfect sanitation was expensive and complicated, and the LCBO's mandate demanded attention to the financial viability of beverage rooms. The LCBO needed to forge a trade off between safety and viability, while maintaining a public drinking system that dissuaded illegal drinking. The subsequent compromise in beverage room glass sanitation tied contemporary chemical sanitizers to the challenging economics of depression-era beverage room management.

    2005-07-01

    A survey of 1,000 people was conducted in Waterloo, Ontario to obtain an idea of public attitudes towards electricity supply issues and environmental issues. Most respondents identified hydropower as the resource most used for generating electricity in Ontario, although nuclear power dominates the province's electricity system. Most respondents expressed their preference for green electricity, particularly solar and wind power, but also felt that the future prospects were better for more traditional resources such as nuclear, hydropower and natural gas. Gender and age helped predict those likely to be more optimistic about green electricity. Perceived consumer effectiveness, liberalism and ecological concern also determined the respondent's choice of future energy source prospects. It was suggested that the broad lessons learned from this study could be applied to other jurisdictions undergoing electricity restructuring. 14 refs., 9 tabs., 1 fig.

    Full Text Available Locational data collected over a one year period from 10 female woodland caribou, Rangifer tarandus caribou, collared with Argos satellite collars in northwestern Ontario, Canada were superimposed on supervised Landsat images using Geographical Information System (GIS technology. Landscape parameters, land cover classifications, and drainage were utilized to create the basemap. Using ARCVIEW software, all digital fixes from collared caribou with information of date, time, and activity status were overlain on the basemap to facilitate a preliminary analysis of habitat use in this species. Results supported the conclusions (1 that woodland caribou in northwestern Ontario select habitats containing high to moderate conifer cover and avoided disturbed areas and shrub-rich habitats, (2 that seasonal changes in habitat utilization occurs in females of this species, and (3 that satellite telemetry technology can be employed in the boreal forest ecosystem to assess habitat utilization by large ungulate species.

    Ontario Hydro presently operates 18 CANDU reactors in the province of Ontario, Canada. All of these reactors are of the CANDU Pressurized Heavy Water design, although their design features differ somewhat reflecting the evolution that has taken place from 1971 when the first Pickering unit started operation to the present as the Darlington units are being placed in service. Over the last three years, two significant neutronic transients took place at the Pickering Nuclear Generating Station 'A' (NGS A) one of which resulted in a number of fuel failures. Both events provided valuable lessons in the areas of operational safety, fuel performance And accident analysis. The events and the lessons learned are discussed in this paper

    1977-01-01

    Antibacterial drug resistance among 219 salmonella isolates recovered during 1974 from poultry and poultry environments at the various production stages of broiler chickens in three integrated Ontario companies are recorded. All isolates were susceptible to ampicillin, trimethroprim-sulfamethoxazole complex, furazolidone, cephaloridine and amoxicillin. A relative increase in resistance to tetracycline and streptomycin with an accompanying decrease in resistance to triple sulfa compound was recorded when compared to a previous investigation of avian salmonella isolates in Ontario. The percentage and patterns of antimicrobial resistance were comparable at the various stages of production. Resistance to tetracycline and streptomycin was the most common pattern found among both Salmonella typhimurium and other serotypes. A notably high prevalence of resistance was found among Salmonella enteritidis isolates including some isolates with R factors for chloramphenicol resistance. This latter finding is of particular concern because of the high prevalence of this serotype in poultry and in human salmonellosis. PMID:318909

    1988-01-01

    The Review commissioned 31 consultants to prepare detailed analyses of specific safety-related questions raised by the design and operation of Ontario Hydro's CANDU reactors. This volume presents 10 of these reports, which I judge to be of sufficient general importance to justify the cost of wide circulation. They have been reproduced precisely as they were submitted. They do not express the Review's own judgements, but do contain a major part of the evidence that influenced those judgements. In several cases the consultants have presented formal recommendations. Some of these have been incorporated, often in modified form, as Review recommendations, in the Minister's Report. Others remain simply as recommendations from the individual consultants. I agree with most of them, but have not seen them as central to the Review's conclusions. I suggest that appropriate institutions--most notably Ontario Hydro and Atomic Energy Control Board--study them, and act as they see fit

  18. Zoning out methadone and rising opioid-related deaths in Ontario: Reforms and municipal government actions.

    Science.gov (United States)

    Strike, Carol; Miskovic, Miroslav

    2017-06-16

    In this commentary, we argue that the use of amendments to bylaws by Ontario cities and municipalities to restrict where and how methadone maintenance treatment (MMT) clinics and pharmacies operate may run counter to efforts to prevent record high rates of opioid-related overdoses. As the province of Ontario seeks to reform the opioid treatment system, it is crucial to understand the structural (e.g., stigma) and treatment system organization factors that drive the actions of municipalities such as those described above. Changes that exacerbate these factors may lead to increased use of bylaws to curtail access at a time when efforts are underway to reduce alarming rates of opioid-related overdose.

    Cisco Coregonus artedi, a historically abundant and commercially important fish in the Great Lakes, have declined drastically in the last century due to the impacts of invasive species, overfishing, and habitat degradation. Chaumont Bay, New York is believed to contain one of the last remaining spawning populations of cisco in Lake Ontario although direct evidence of spawning has remained elusive. We document cisco spawning in Chaumont Bay for the first time in decades through the use of an egg pumping device specifically developed to sample through lake ice. Forty-one eggs were identified as cisco using genetic barcoding of the mitochondrial cytochrome c oxidase I (COI) gene. Cisco eggs were associated with shallow, rocky shoals. Contemporary knowledge of spawning behavior is an important step toward the successful restoration of cisco in Lake Ontario and across the Great Lakes.

    Microplastics contamination of Lake Ontario sediments is investigated with the aim of identifying distribution patterns and hotspots in nearshore, tributary and beach depositional environments. Microplastics are concentrated in nearshore sediments in the vicinity of urban and industrial regions. In Humber Bay and Toronto Harbour microplastic concentrations were consistently >500 particles per kg dry sediment. Maximum concentrations of ~28,000 particles per kg dry sediment were determined in Etobicoke Creek. The microplastic particles were primarily fibres and fragments microplastics in terms of how and where to implement preventative measures to reduce the contaminant influx. Although the impacts of microplastics contamination on ecosystem health and functioning is uncertain, understanding, monitoring and preventing further microplastics contamination in Lake Ontario and the other Great Lakes is crucial.

    The objective of the study was to determine the proportion of practitioners from Ontario, Canada who perform onychectomy, identify the techniques utilized, and obtain practitioners views on the procedure. An anonymous survey was distributed to Ontario Veterinary Medical Association members. Mann-Whitney U-tests were used to compare responses of opinion questions related to declawing between respondents who indicated they perform declawing procedures and those who do not. Of 500 respondents, 75.8% reported performing onychectomy, with 60.1% of those reporting performing the procedure less than monthly and 73.3% only performing the procedure after recommending alternatives. Statistically significant differences were found between those who do and those who do not perform onychectomy for perception of procedural pain, concept of mutilation, perception of procedural necessity for behavior modification or prevention of euthanasia, and support of province-wide procedural bans.

    Full Text Available In this paper, a biofuel production supply chain optimization framework is developed that can supply the fuel demand for 10% of Ontario. Different biomass conversion technologies are considered, such as pyrolysis and gasification and subsequent hydro processing and the Fischer-Tropsch process. A supply chain network approach is used for the modeling, which enables the optimization of both the biorefinery locations and the associated transportation networks. Gasification of corn stover is examined to convert waste biomass into valuable fuel. Biomass-derived fuel has several advantages over traditional fuels including substantial greenhouse gas reduction, generating higher quality synthetic fuels, providing a use for biomass waste, and potential for use without much change to existing infrastructure. The objective of this work is to show the feasibility of the use of corn stover as a biomass feedstock to a hydrocarbon biofuel supply chain in Ontario using a mixed-integer linear programming model while accounting for the uncertainty in the availability of corn stover. In the case study, the exact number of biorefineries is left as a policy decision and the optimization is carried out over a range of the possible numbers of facilities. The results obtained from the case study suggests implementing gasification technology followed by Fischer-Tropsch at two different sites in Ontario. The optimal solution satisfied 10% of the yearly fuel demand of Ontario with two production plants (14.8 billion L of fuel and requires an investment of $42.9 billion, with a payback period of about 3 years.

    Full Text Available Woodland caribou {Rangifer tarandus caribou range across northern Ontario, occurring in both the Hudson Bay Lowlands and the Boreal Forest. Woodland caribou extend south well into the merchantable forest, occurring in licensed and/or actively managed Forest Management Units (FMU's across the province. Caribou range has gradually but continuously receded northward over the past century. Since the early 1990's, the Ontario Ministry of Natural Resources (OMNR has been developing and implementing a woodland caribou habitat management strategy in northwestern Ontario. The purpose of the caribou habitat strategy is to maintain woodland caribou occupancy of currently occupied range in northwestern Ontario. Long-term caribou habitat needs and predator-prey dynamics form the basis of this strategy, which requires the development of a landscape-level caribou habitat mosaic across the region within caribou range. This represents a significant change from traditional forest management approaches, which were based partially upon moose (Alces alces habitat management principles. A number of issues and concerns regarding implications of caribou management to the forest industry are being addressed, including short-term and long-term reductions in wood supply and wood quality, and increased access costs. Other related concerns include the ability to regenerate forests to pre-harvest stand conditions, remote tourism concerns, implications for moose populations, and required information on caribou biology and habitat. The forest industry and other stakeholders have been actively involved with the OMNR in attempting to address these concerns, so that caribou habitat requirements are met while ensuring the maintenance of a viable timber industry, other forest uses and the forest ecosystem.

    The challenge facing Ontario in gaining access to affordable, flexible and reliable energy at a time when energy demand is escalating was discussed. The Durham Strategic Energy Alliance (DSEA) was created in 2005 to position Ontario's Durham Region as a Canadian leader in timely, sustainable and reliable energy solutions. Durham employs about 10,000 workers directly in the energy industry. The region also produces nearly 30 per cent of the province's power from local generating stations. It is also home to an energy focused teaching and research institution at the University of Ontario Institute of Technology. The DSEA is composed of business, industry, government and academic institutions committed to taking action on advancing energy solutions in all aspects of the energy life-cycle. Members have a stake in promoting sustainable energy solutions in energy supply and generation, manufacturing of energy solutions, transmission, distribution, conservation and/or consumption of all forms of energy. Since its creation, the DSEA has taken measures to exploit the energy opportunities in Durham Region and plans to significantly expand its activities in the future, particularly in building commercialization capabilities through an energy cluster. New links and formalized networks will be established to achieve this goal. Innovative networks will be developed to connect Durham's academic community with business, industry and energy clusters which are developing globally. The overall DSEA strategy is to develop Durham's energy cluster so that it evolves quickly into Ontario's energy commercialization center. There are three areas where such strategy will be recognized: energy technology adoption/demonstration centre; energy technology adoption officer; and, energy cluster outreach/network. 1 fig

    A large body of evidence clearly shows that cancer patients experience significant health benefits with smoking cessation. Cancer Care Ontario, the provincial agency responsible for the quality of cancer services in Ontario, has undertaken a province-wide smoking cessation initiative. The strategies used, the results achieved, and the lessons learned are the subject of the present article. Evidence related to the health benefits of smoking cessation in cancer patients was reviewed. A steering committee developed a vision statement for the initiative, created a framework for implementation, and made recommendations for the key elements of the initiative and for smoking cessation best practices. New ambulatory cancer patients are being screened for their smoking status in each of Ontario's 14 regional cancer centres. Current or recent smokers are advised of the benefits of cessation and are directed to smoking cessation resources as appropriate. Performance metrics are captured and used to drive improvement through quarterly performance reviews and provincial rankings of the regional cancer centres. Regional smoking cessation champions, commitment from Cancer Care Ontario senior leadership, a provincial secretariat, and guidance from smoking cessation experts have been important enablers of early success. Data capture has been difficult because of the variety of information systems in use and non-standardized administrative and clinical processes. Numerous challenges remain, including increasing physician engagement; obtaining funding for key program elements, including in-house resources to support smoking cessation; and overcoming financial barriers to access nicotine replacement therapy. Future efforts will focus on standardizing processes to the extent possible, while tailoring the approaches to the populations served and the resources available within the individual regional cancer programs.

    Purpose: To describe the use of palliative radiotherapy (PRT) for bone metastases in Ontario between 1984 and 2001 and identify factors associated with the choice of fractionation. Methods and Materials: Electronic RT records from the nine provincial RT centers in Ontario were linked to the Ontario Cancer Registry to identify all courses of PRT for bone metastases. Results: Between 1984 and 2001, 44,884 patients received 74,432 courses of PRT for bone metastases in Ontario. The mean number of courses per patient was 1.7, and 65% of patients received only a single course of PRT for bone metastasis. The mean number of fractions per course was 3.9. The proportion of patients treated with a single fraction increased from 27.2% in 1984-1986 to 40.3% in 1987-1992 and decreased thereafter. Single fractions were used more frequently in patients with a shorter life expectancy, in older patients, and in patients who lived further from an RT center. Single fractions were used more frequently when the prevailing waiting time for RT was longer. There were wide variations in the use of single fractions among the different RT centers (intercenter range, 11.8-62.3%). Intercenter variations persisted throughout the study period and were not explained by differences in case mix. Conclusions: Despite increasing evidence of the effectiveness of single-fraction PRT for bone metastases, most patients continued to receive fractionated PRT throughout the two decades of this study. Single fractions were used more frequently when waiting times were longer. There was persistent, unexplained variation in the fractionation of PRT among different centers

  17. Analysis of passive-sampler monitored atmospheric ammonia at 74 sites across southern Ontario, Canada

    Weekly/biweekly concentrations of atmospheric NH3 were collected using passive samplers at 74 sites across southern Ontario, Canada during the period from June 2006 to March 2007 with tens of sites running as early as March 2006. The annual average of NH3 (AAN) at all the sites across southwestern Ontario was over 1 µg m-3, a value that was recently proposed as the new critical level for protecting vegetation. High ANN values (3.6-6.1 µg m-3) were observed at eight sites located inside the intensive livestock production zones. The AAN values at the sites across southeastern Ontario were generally less than 1 µg m-3 and the values were less than 0.4 µg m-3 at non-agricultural sites. Regional transport from the southwest region to the southeast region was identified to be the main contributor to the observed NH3 at the southeastern non-agricultural sites. However, different transport mechanisms were proposed in different seasons. The transport of NH3 produced through bi-directional air-surface exchange along air mass trajectories was believed to be the main mechanism in the hot seasons while the transport of NH4NO3 produced at source locations followed by its evaporation at receptor sites was thought to be dominant in the cold seasons. A sharp increase in NH3 concentration was surprisingly observed at 20 out of the 74 sites during the coldest two weeks when ambient temperature was lower than -7 °C, and cannot be explained by known sources or with existing knowledge. Recently developed NH3 emission inventory for southern Ontario was also evaluated with the measurement data and emissions within two small zones were identified to be potentially underestimated.

    All Canadian immigrants undergo screening for tuberculosis (TB) before immigration, and selected immigrants must undergo postimmigration surveillance for the disease. We sought to quantify the domestic health impact of screening for TB in all new immigrants and to identify mechanisms to enhance effectiveness and efficiency of this screening. We linked preimmigration medical examination records from 944,375 immigrants who settled in Ontario between 2002 and 2011 to active TB reporting data in Ontario between 2002 and 2011. Using a retrospective cohort study design, we measured birth country-specific rates of active TB detected through preimmigration screening and postimmigration surveillance. We then quantified the proportion of active TB cases among residents of Ontario born abroad that were detected through postimmigration surveillance. Using Cox regression, we identified independent predictors of active TB postimmigration. Immigrants from 6 countries accounted for 87.3% of active TB cases detected through preimmigration screening, and 10 countries accounted for 80.4% of cases detected through postimmigration surveillance. Immigrants from countries with a TB (all-sites) incidence rate of less than 30 cases per 100 000 persons resulted in pre- and postimmigration detection of 2.4 and 0.9 cases per 100 000 immigrants, respectively. Postimmigration surveillance detected 2.6% of active TB cases in Ontario residents born abroad, and TB was detected a median of 18 days earlier in those undergoing surveillance than in those who were not referred to surveillance or who did not comply. Predictors of active TB postimmigration included radiographic markers of old TB, birth country, immigration category, location of application for residency, immune status and age. Universal screening for TB in new immigrants has a modest impact on the domestic burden of active TB and is highly inefficient.

  20. Participating in Ontario's competitive electricity market: an overview by the Independent Electricity Market Operator

    International Nuclear Information System (INIS)

    1999-12-01

    In Ontario's new competitive electricity market, suppliers will sell their product in new ways by offering choices to consumers for the first time, and generators from both within and without the province can participate in providing electricity to Ontario clients. Businesses and industries for whom electric power is a large part of their overall costs ought to consider the new option of participating directly in the wholesale market by buying and selling electric power themselves. At the opening of the new market, the manner in which electric power is purchased and sold will undergo a basic change: at the wholesale level, purchasers will be capable of submitting price bids for electric power and suppliers will be able to submit offers. These bids and offers are stacked by increasing price to be matched with the constantly changing demand for electric power throughout each day to determine which bids and offers are accepted. The Electricity Act ended the previous monopoly system for generating and selling electricity in Ontario, and created five new companies from the former Ontario Hydro. The Independent Electricity Market Operator (IMO) is completing the Market Rules for IMO administered markets in consultation with industry for approval by the government. The new wholesale electricity market provides equal, unbiased access to all generators, buyers, and sellers who are qualified to participate. The success of the market depends on wholesale market rules that promote competition, provide a level playing field, ensure the reliability of electric power, and facilitate new investments. The main roles of the IMO are to oversee the IMO-administered markets and to ensure the reliability of the integrated power system. For businesses to consider whether to become an active market participant the following categories apply: the generating of electric power, the importing or exporting of electric power, managing the amount of electricity used at different times as well as

    2012-01-01

    The development of feed-in tariff (FIT) programs to support green electricity in Ontario (the Green Energy and Green Economy Act of 2009) and Germany (the Erneuerbare Energien-Gesetz of 2000) is compared. The two policies are highly comparable, offering similar rates for most renewable electricity technologies. Major differences between the policies include the level of differentiation found in the German policy, as well as the use of a price degression strategy for FIT rates in Germany compared to an escalation strategy in Ontario. The German renewable electricity portfolio is relatively balanced, compared to Ontario where wind power dominates the portfolio. At the federal level, Canada does not yet have a policy similar to the European Directive on Renewable Energy, and this lack may impact decisions taken by manufacturers of renewable technologies who consider establishing operations in the province. Ontario's Green Energy and Green Economy Act could be benefit from lessons in the German system, especially with regard to degression of feed-in tariff rates over time, which could significantly reduce payments to producers over the course of a contract, and in turn encourage greater competitiveness among renewable power providers in the future. - Highlights: ► We compare two jurisdictions that utilize feed-in tariffs to support renewable electricity. ► Complementary policy such as mandated renewable energy use in conjunction with tariffs increases certainty for investors. ► Targeted incentives in the form of adders can deliver more diversity in renewable generation capacity. ► Degression of tariff rates delivers renewable generation capacity at lower cost.

    Full Text Available Micro-scale/small wind turbines, unlike larger utility-scale turbines, produce electricity at a rate of 300 W to 10 kW at their rated wind speed and are typically below 30 m in hub-height. These wind turbines have much more flexibility in their costs, maintenance and siting, owing to their size, and can provided wind energy in areas much less suited for direct supply to the grid system. In the future under climate change, the energy landscape will likely shift from the present centralized electricity generation and delivery system to a more distributed and locally-generated electricity and delivery system. In the new system configuration, the role of relatively small sustainable electricity generators like small wind turbines will likely become more prominent. However, the small wind industry has been substantially slow to progress in Ontario, Canada, and there is much debate over its viability in a growing energy dependent economy. This study seeks to demonstrate the performance of a small wind turbine, and speculate on its potential power output and trend over Ontario historically over the last 33 years using the North American Regional Reanalysis (NARR data. We assessed the efficiency of a Bergey Excel 1 kW wind turbine at the pre-established Kortright Centre for Conservation test site, located north of Toronto. Using a novel approach, the Bergey optimized power curve was incorporated with reanalysis data to establish power output across Ontario at three-hour resolution. Small turbine-based wind power around the Great Lakes and eastern James Bay increased during winter and fall, contributing up to 10% of the annual electricity demand in some regions in Ontario. We purport that increases in power output are driven by long-term reductions in sea and lake ice concentrations affecting atmospheric stability in surrounding regions.

    Full Text Available Fentanyl is prescribed to patients suffering from severe chronic pain. Transdermal patches are the best mode of delivery for patients who have developed tolerance for opioids. However, used patches still contain fentanyl that can be extracted and misused, with potentially severe consequences. To address this issue, patients who are prescribed fentanyl patches in Ontario are now required to return previously dispensed patches to receive new patches under the Safeguarding Our Communities Act: Patch for Patch (P4P Return Policy. The problem is significant in Ontario because the province has the largest annual dispense rate of high-dose prescription fentanyl (112 units per 1,000 population in Canada even though the prevalence rate of chronic pain is lower than the national reported range (16.6% in Ontario versus 19.6 to 21.9% in other provinces, according to Gomes et al. 2014. The primary goal of this reform is to instill responsible use of fentanyl patches, and to improve safety for patients and the public by having a central disposal process. The reform was modeled after a community initiative that was pioneered in North Bay after receiving great support from health professional colleges and communities that voluntarily integrated the program prior to the introduction of Bill 33. Preliminary data suggest that the P4P policy is positively received by health professionals, although ongoing evaluation is needed to assess the effectiveness of the policy in reducing misuse and abuse of prescribed fentanyl patches.

    Canada supplies nearly 100 per cent of U.S. electricity imports. By 2025, U.S. energy demand is expected to rise by 30 per cent. This PowerPoint presentation examined the relevance of recent developments in the United States to Ontario's electricity sector. A chart of U.S.-Canada energy trade from 1990 to 2002 was presented. It was noted that the Federal Energy Regulatory Commission (FERC) has increased its emphasis on reliability in response to recommendations by the U.S.-Canada Power System Outage Task Force Report. The creation of the Electric Reliability Organization (ERO) was discussed. An outline of the current reliability framework was presented, along with a map of National Electric Reliability Council (NERC) regions. Issues concerning mandatory compliance with reliability standards were examined with reference to various provinces in Canada. It was noted that achieving mandatory and enforceable standards in the U.S. has been a high priority for Canadian entities. An overview of U.S. legislation relating to reliability standards was presented. An outline of current and proposed regional transmission organizations (RTOs) in North America was presented, along with outlines of their reliability and planning protocols. A map of current transmission lines was presented. The implications of independent system operator (ISO) and RTO developments for Ontario were reviewed. Issues concerning emissions reductions and renewable energy credits trading were discussed. It was concluded that reliability legislation will be a positive development for Ontario, Canada, and U.S. jurisdictions. tabs., figs

    2011-01-01

    Traits that converge in appearance under similar environmental conditions among phylogenetically independent lineages are thought to represent adaptations to local environments. We tested for convergence in nest morphology and composition of birds breeding in two ecologically different locations in Canada: Churchill in northern Manitoba and Elgin in southeastern Ontario. We examined nests from four families of passerine birds (Turdidae: Turdus, Parulidae: Dendroica, Emberizidae: Passerculus and Fringillidae: Carduelis) where closely related populations or species breed in both locations. Nests of American Robins, Yellow Warblers, and Carduelis finches had heavier nest masses, and tended to have thicker nest-walls, in northern Manitoba compared with conspecifics or congenerics breeding in southeastern Ontario. Together, all species showed evidence for wider internal and external nest-cup diameters in northern Manitoba, while individual species showed varying patterns for internal nest-cup and external nest depths. American Robins, Yellow Warblers, and Carduelis finches in northern Manitoba achieved heavier nest masses in different ways. American Robins increased all materials in similar proportions, and Yellow Warblers and Common Redpolls used greater amounts of select materials. While changes in nest composition vary uniquely for each species, the pattern of larger nests in northern Manitoba compared to southeastern Ontario in three of our four phylogenetically-independent comparisons suggests that birds are adapting to similar selective pressures between locations.

Together, all species showed evidence for wider internal and external nest-cup diameters in northern Manitoba, while individual species showed varying patterns for internal nest-cup and external nest depths. American Robins, Yellow Warblers, and Carduelis finches in northern Manitoba achieved heavier nest masses in different ways. American Robins increased all materials in similar proportions, and Yellow Warblers and Common Redpolls used greater amounts of select materials. While changes in nest composition vary uniquely for each species, the pattern of larger nests in northern Manitoba compared to southeastern Ontario in three of our four phylogenetically-independent comparisons suggests that birds are adapting to similar selective pressures between locations.

    Full Text Available The range of Ontario’s woodland caribou (Rangifer tarandus caribou (forest-dwelling ecotype has receded northward substantially over many decades, leading to its current Threatened designation. Ontario released its Caribou Conservation Plan (CCP in the fall of 2009. This policy responded to public input and recommendations from the Ontario Woodland Caribou Recovery Team and the Caribou Science Review Panel, and outlines conservation and recovery actions to conserve and recover caribou. Within an adaptive management framework, the CCP builds upon a recent history of managing at large landscape scales in Ontario to implement a range management approach as the basis for recovery actions. These commitments and actions include enhanced research and monitoring, improved caribou habitat planning at the landscape scale, an integrated range analysis approach using advanced assessment tools to evaluate thresholds of habitat amount, arrangement and disturbance, the assessment of probability of persistence, consideration of cumulative effects, meeting forest management silvicultural performance requirements, consideration of caribou recovery implications when managing other wildlife, an initial focus on the southern edge of caribou distribution where threats are most significant, improved outreach and stewardship, and consideration of Aboriginal Traditional Knowledge in recovery actions. Implementation of the CCP signifies a long-term provincial commitment to caribou recovery, initially focusing on identified priorities within the CCP.

    A workshop on seismic hazard assessment in southern Ontario was conducted on June 19-21, 1995. The purpose of the workshop was to review available geological and seismological data which could affect earthquake occurrence in southern Ontario and to develop a consensus on approaches that should be adopted for characterization of seismic hazard. The workshop was structured in technical sessions to focus presentations and discussions on four technical issues relevant to seismic hazard in southern Ontario, as follows: The importance of geological and geophysical observations for the determination of seismic sources; Methods and approaches which may be adopted for determining seismic sources based on integrated interpretations of geological and seismological information. Methods and data which should be used for characterizing the seismicity parameters of seismic sources. Methods for assessment of vibratory ground motion hazard. This document presents transcripts from recordings made of the presentations and discussion from the workshop. It will be noted, in some sections of the document, that the record is incomplete. This is due in part to recording equipment malfunction and in part due to the poor quality of recording obtained for certain periods

    Full Text Available The incidence of extreme school violence as a direct consequence of bullying among peers, exacerbated by vast media attention, has caused educational institutions worldwide to put bullying intervention and prevention strategies into operation. This study focused on an overview of two provincewide antibullying incentives in the Canadian provinces of Ontario and Saskatchewan, and an analysis of the quality of their respective antibullying policies. An itemized list of beneficial practices for bullying intervention and prevention originated from Smith, Smith, Osborn and Samara (2008’s scoring scheme. The scoring scheme was adapted to the current study by linking research-based program elements that have been found to be effective in reducing school bullying to a content analysis of both provincial frameworks. The final scoring scheme comprised a total of 39 criterions, divided into five categories: Defining Bullying Behaviors, Establishing a Positive School Climate, Disseminating, Monitoring and Reviewing Policy, Reporting and Responding to Bullying, and Involving the Broader Community. Results showed that policies contained a total average of 60% of the criterions in Ontario, and 59% in Saskatchewan. The conclusion of this study observes from policy lenses key essentials of bullying intervention and prevention initiatives in elementary and secondary educational settings. Recommendations are proposed to bridge the gap between areas that have received extensive attention and areas that have received less treatment in bullying intervention and prevention endeavors, using the content of Ontario and Saskatchewan policies as a basis for discussion.

    Adolescents admitted to youth custody facilities are often in need of physical and mental health care. To describe primary health care practices in Ontario's youth custody facilities. A questionnaire regarding facility characteristics and primary health care practices was distributed to the directors of all youth custody facilities in Ontario. Most (87.8%) facilities obtained medical histories after the youth arrived, and 92% used health care professionals to perform that assessment. Intake medical examinations were performed on each youth admitted to custody at 94% of all facilities; however, only 57.2% of facilities reported that these examinations were performed by a doctor within 72 h of admission. Performing suicide assessments on all youth at intake was reported by 77.6% of facilities. Continuous health education was provided by 76% of facilities. Facility type and type of management appear to be related to some areas of health services provision. Youth custody facilities in Ontario are providing primary health care services. Weaknesses are, however, evident, particularly in relation to untimely intake medical examinations, failure to provide continuous health education and failure to conduct suicide assessments on all youth at intake. Future research on barriers to health service provision in Canadian youth custody facilities is recommended.

    Intimate partner violence (IPV) affects 4 in 10 women in North America in their lifetime and 13-27 % in the past year. The basis for estimates stems largely from studies involving Caucasian women. Less is known about other minority populations such as South Asian women. This study aimed to assess the prevalence of IPV in the past year among South Asian women living in Southern Ontario. We conducted a survey of South Asian women living in Southern Ontario. All adult self-identified South Asian women attending a cultural event celebrating South Asian women who could understand English or Punjabi were eligible to participate. The survey contained three IPV prevalence questions adapted from the Woman Abuse Screening Tool. A total of 188 women (45 % of potentially eligible women) participated. Nearly 1 in 5 women reported IPV within the past year (19.3 %, 95 % CI 13.9-26.1 %). In this study single women were significantly more likely to have experienced IPV in the past year compared to married women (p = 0.035). Self-identified immigrant and non-immigrant South Asian women in this sample of women living in Southern Ontario experienced violence in proportions comparable to the general population. Programs for women should ensure accessibility and support of all ethnicities given equivalent rates of violence in the community.

    Full Text Available Introduction The Ontario Stroke System was developed to enhance the quality and continuity of stroke care provided across the care continuum. Research Objective To identify the role evidence played in the development and implementation of the Ontario Stroke System. Methods This study employed a qualitative case study design. In-depth interviews were conducted with six members of the Ontario Stroke System provincial steering committee. Nine focus groups were conducted with: Regional Program Managers, Regional Education Coordinators, and seven acute care teams. To supplement these findings interviews were conducted with eight individuals knowledgeable about national and international models of integrated service delivery. Results Our analyses identified six themes. The first four themes highlight the use of evidence to support the process of system development and implementation including: 1 informing system development; 2 mobilizing governmental support; 3 getting the system up and running; and 4 integrating services across the continuum of care. The final two themes describe the foundation required to support this process: 1 human capacity and 2 mechanisms to share evidence. Conclusion This study provides guidance to support the development and implementation of evidence-based models of integrated service delivery.

  15. Demand-side management and demand response in the Ontario energy sectors

    A directive from the former Minister of Energy was received by the Ontario Energy Board (OEB), directing the Board to consult with stakeholders on options for the delivery of demand-side management (DSM) and demand response (DR) activities within the electricity sector, including the role of local distribution companies in such activities. The implementation costs were to be balanced with the benefits to both consumers and the entire system. The scope of the review was expanded by the Board to include the role of gas distribution companies in DSM. A consultation process was implemented and stakeholders were invited to participate. A series of recommendations was made, including: (1) a hybrid framework utilizing market-based and public-policy approaches should deliver DSM and DR activities in Ontario's energy markets, (2) DSM and DR activities should come under the responsibility of a central agency, (3) DSM and DR activities should be coordinated through cooperation between the Ministry of Energy, the Independent Electricity Market Operator (IMO) and the Ontario Energy Board, (4) regulatory mechanisms to induce gas distributors, electricity transmitters and electricity distributors to reduce distribution system losses should be put in place, (5) all electricity consumers should fund electricity DSM and some retail DR initiatives through a transparent, non-bypassable consumption charge, and (6) the Board should design, develop and deliver information to consumers regarding energy conservation, energy efficiency, load management, and cleaner sources of energy. refs., 4 figs

    We conducted two surveys of Ontario (Canada) fishers: a stratified sample of licensed anglers in two Lake Ontario communities (anglers, n=232) and a shore and community-based sample in five Great Lakes' Areas of Concern (AOC eaters, n=86). Among the 176 anglers consuming their catch, the median number of sport-fish meals/year was 34.2 meals and 10.9, respectively, in two communities, with a mean blood total mercury level among these sport-fish consumers of 2.8 μg/L. The vast majority of fish eaten by AOC eaters was from Ontario waters (74%). For AOC eaters, two broad country-of-origin groups were assembled: Euro-Canadians (EC) and Asian-Canadians (AC). EC consumed a median of 174 total fish meals/year and had a geometric mean total mercury level of 2.0 μg/L. Corresponding AC figures were 325 total fish meals/year and 7.9 μg/L. Overall, mercury levels among AOC eaters were higher than in many other Great Lakes populations but lower than in populations frequently consuming seafood. In multivariate models, mercury levels were significantly associated with levels of fish consumption among both anglers and EC AOC eaters. Given the nutritional and social benefits of fish consumption, prudent species and location choices should continue

    We determined polychlorinated biphenyl (PCB) concentrations in 61 female lake trout (Salvelinus namaycush) and 71 male lake trout from Lake Ontario (Ontario, Canada and New York, United States). To estimate the expected change in PCB concentration due to spawning, PCB concentrations in gonads and in somatic tissue of lake trout were also determined. In addition, bioenergetics modeling was applied to investigate whether gross growth efficiency (GGE) differed between the sexes. Results showed that, on average, males were 22% higher in PCB concentration than females in Lake Ontario. Results from the PCB determinations of the gonads and somatic tissues revealed that shedding of the gametes led to 3% and 14% increases in PCB concentration for males and females, respectively. Therefore, shedding of the gametes could not explain the higher PCB concentration in male lake trout. According to the bioenergetics modeling results, GGE of males was about 2% higher than adult female GGE, on average. Thus, bioenergetics modeling could not explain the higher PCB concentrations exhibited by the males. Nevertheless, a sexual difference in GGE remained a plausible explanation for the sexual difference in PCB concentrations of the lake trout.

    Concentrations of current-use pesticides (CUPs) in water, zooplankton, precipitation, and air samples as well as stereoisomer fractions (SF; herbicidally active/total stereoisomers) of metolachlor were determined in water samples collected from 10 remote inland lakes in Ontario, Canada, between 2003 and 2005. The most frequently detected chemicals in lake water, precipitation, and air were α-endosulfan, atrazine, metolachlor, chlorpyrifos, chlorothalonil, and trifluralin, and α-endosulfan and chlorpyrifos were the chemicals detected frequently in zooplankton. Air concentrations of these CUPs were within the range of previously reported values for background sites in the Great Lakes basin. High detection frequency of CUPs in lake water and precipitation was attributed to high usage amounts, but some CUPs such as ametryn and disulfoton that were not used in Ontario were also detected. Mean bioaccumulation factors (wet wt) in zooplankton for endosulfan ranged from 160 to 590 and from 20 to 60 for chlorpyrifos. The overall median SF of metolachlor in precipitation samples (0.846) was similar to that of the commercial S-metolachlor (0.882). However, the median SF of metolachlor in water from all sampled inland lakes (0.806) was significantly lower compared with Ontario rivers (0.873) but higher compared with previous measurements in the Great Lakes (0.710). Lakes with smaller watershed areas showed higher SFs, supporting the hypothesis of stereoselective processing of deposited metolachlor within the watersheds, followed by transport to the lakes.

    The Ministry of Health and Long-Term Care mandated a rapid and thorough change in the delivery of cancer services in Ontario to integrate ambulatory services offered by Cancer Care Ontario (CCO) with the inpatient services of affiliated hospitals. The CCO Surgical Oncology Program held a strategic planning retreat to establish the basis upon which to implement surgery-specific changes. Participants completed a pre-retreat survey. Based on survey results, the retreat was organized around 4 themes: role of the Surgical Oncology Program; knowledge transfer; funding for cancer surgery; and research priorities. These topics were discussed in small breakout groups and by the entire assembly. Retreat participants (n = 55) included hospital CEOs, vice-presidents of cancer services, surgeons from cancer centres and community hospitals, academic chairs of surgery, clinician researchers and managers from CCO. Responses to the pre-retreat survey (n = 38) and recommendations made by retreat participants showed strong support for the Surgical Oncology Program to take a leadership role in the development and monitoring of quality indicators, research related to cancer surgery and the creation of regional communities of practice. Funding mechanisms for cancer surgeons and hospitals performing cancer surgery were also highlighted. The Surgical Oncology Program used the results to develop a strategic plan that was approved by retreat participants and the board of the CCO. The program has embarked on a multifaceted approach to facilitate, monitor and report on the organization and delivery of cancer surgery in Ontario.

    To determine the prevalence and diversity of Leptospira serogroups circulating in wildlife on farms in Ontario, we tested samples from 51 raccoons (Procyon lotor), seven skunks (Mephitis mephitis), four rats (Rattus norvegicus), and three opossums (Didelphis virginiana) that were trapped on 27 livestock (swine [Sus scrofa], cattle [Bos taurus]) farms in 2010. Seventeen of 51 raccoons (33%; 95% confidence interval [CI], 21-48%) sampled were positive for at least one Leptospira serogroup using the microscopic agglutination test. None of the other 14 animals had detectable Leptospira antibodies. On swine farms, 13 of 30 raccoons (43%; 95% CI, 27-61%) were antibody positive, and on cattle farms, four of 21 raccoons (19%; 95% CI, 8-40%) were positive. Leptospira antibody prevalence in raccoons did not differ between swine and cattle farms. Raccoons were positive to serovars representative of serogroups Grippotyphosa, Australis, Icterohaemorrhagiae, and Pomona and were negative to serovars of serogroups Autumnalis, Canicola, and Sejroe. The prevalence of Leptospira antibodies in raccoons in this study is similar to what has been reported previously; however, the diversity of serogroups was higher in this study than what has been reported in raccoons from an urban area of Ontario, Canada. Understanding the prevalence and distribution of Leptospira serogroups in wildlife in Ontario, Canada, is important for the development and maintenance of appropriate disease management strategies in humans, livestock, and companion animals.
