Canada's Air Quality: Health Canada's Role And Responsibility

Air pollution is a pressing issue in Canada, with Health Canada estimating that it contributes to around 15,300-17,400 premature deaths in the country each year. The organisation also calculates the economic costs of these health impacts, which amount to billions of dollars annually. This article will explore Health Canada's role in addressing air pollution and its health impacts, including the policies and regulations it implements to improve air quality and protect Canadians' health.

Health Canada estimates that air pollution in 2018 contributed to about 17,400 premature deaths in Canada

Health Canada plays an important role in monitoring and assessing the health impacts of air pollution in the country. It does this by estimating exposures to ambient air pollution across Canada, evaluating the associated adverse health impacts on the population, and calculating the corresponding economic costs of these health impacts.

Health Canada's analysis takes into account national demographics, including population counts, age profiles, and baseline health status. This comprehensive approach allows the organisation to quantitatively estimate the population health impacts of air pollution, which is a well-established method used by international health science organisations.

In 2018, Health Canada estimated that air pollution contributed to about 17,400 premature deaths in Canada. This figure includes the impacts of above-background air pollution, which refers to air pollution levels that exceed the natural or typical levels in a given area. The modelling showed that the national average exposures to air pollution during 2017-2019 were higher than desired for several pollutants, including PM2.5 and NO2.

The health impacts of air pollution in Canada are expected to worsen in the future due to climate change. Unless these impacts are mitigated by reducing air pollution, the number of premature deaths and illnesses attributed to air pollution is projected to increase. Therefore, it is crucial for Health Canada to continue its efforts in monitoring and assessing the health impacts of air pollution to inform policies and regulations aimed at improving air quality and protecting the health of Canadians.

Air pollution is a leading environmental cause of death and illness in Canada

Health Canada has published reports on the health impacts of air pollution, which rely on data and scientific knowledge, including ambient air pollution exposure estimates and demographic data. The reports estimate exposures to ambient air pollution across Canada, the associated adverse health impacts in the population, and the corresponding economic costs of these health impacts. The approach for quantitatively estimating the population health impacts of air pollution is well-established by international health science organisations.

The focus on above-background air pollution is relevant to air quality management in Canada because policies and regulations to improve air quality generally target human-made emissions. Modelling showed that above-background national average exposures to air pollution in 2017 to 2019 were 5.32 µg/m3 for PM2.5, 7.11 ppb for NO2, 11.16 ppb for annual O3 and 12.39 ppb for summer O3. These averages are weighted by population to account for the geographic distribution of Canada's population.

The health impacts of air pollution in Canada are expected to worsen in the future due to the influence of climate change. Unless these impacts are offset by reducing air pollution, hundreds of deaths annually are expected to result by mid-century. Increasing wildfire emissions are one of the most significant climate-related risks to air quality in Canada.

Air pollution has been linked to increased heart and breathing problems, hospitalisations and emergency room visits

Health Canada has published several reports on the health impacts of air pollution. These reports rely on data and scientific knowledge, including ambient air pollution exposure estimates and demographic data. The reports estimate exposures to ambient air pollution across Canada, the associated adverse health impacts, and the corresponding economic costs. This analysis accounts for national demographics, including population counts, age profiles, and baseline health status.

These averages are weighted by population to account for the geographic distribution of Canada's population.

Health Canada estimates that above-background air pollution, including air pollution from human sources in North America, contributes to 15,300 premature deaths per year in Canada. The health impacts of air pollution in Canada, including premature death and disease, are expected to worsen in the future due to the influence of climate change. Unless these impacts are offset by reducing air pollution, hundreds of deaths annually are expected to result by mid-century.

Health Canada estimated the economic costs of the health impacts of air pollution

Health Canada plays an important role in monitoring and assessing the health impacts of air pollution in the country. It publishes reports on the health impacts of air pollution, relying on data and scientific knowledge, including ambient air pollution exposure estimates and demographic data.

The report also estimated exposures to ambient air pollution across Canada, the associated adverse health impacts, and the corresponding economic costs. This analysis accounted for national demographics, including population counts, age profiles, and baseline health status.

Health Canada's modelling showed that above-background national average exposures to air pollution in the years 2017 to 2019 were 5.32 µg/m3 for PM2.5, 7.11 ppb for NO2, 11.16 ppb for annual O3, and 12.39 ppb for summer O3. These averages are weighted by population to account for the geographic distribution of Canada's population.

The health impacts of air pollution in Canada are expected to worsen in the future due to the influence of climate change. Unless these impacts are offset by reducing air pollution, hundreds of additional deaths annually are expected by mid-century. Increasing wildfire emissions are one of the most significant climate-related risks to air quality in Canada.

Air pollution from wildfires is one of the most significant climate-related risks to air quality in Canada

Health Canada has also estimated that above-background air pollution, including pollution from human sources in North America, contributes to 15,300 premature deaths per year in Canada. This figure is expected to worsen in the future due to the influence of climate change, with hundreds of additional deaths expected annually by mid-century unless these impacts are offset by reducing air pollution.

The focus of air quality management in Canada has been on above-background air pollution, which is relevant to human-made emissions.

Health Canada plays a crucial role in understanding and mitigating the health impacts of air pollution in the country. The organisation publishes reports on the health impacts of air pollution, relying on data and scientific knowledge. These reports estimate exposures to ambient air pollution across Canada, the associated adverse health impacts, and the corresponding economic costs. By aligning with established approaches from international health science organisations, Health Canada contributes to the development of policies and regulations aimed at improving air quality and protecting the health of Canadians.
