The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Air health trends indicators were developed as a tool to monitor trends in public health impacts in Canada attributable to short-term exposure to 2 major outdoor air pollutants: ground-level ozone (O3) and fine particulate matter (PM2.5). Specifically, the indicators estimate over time the change in the percentage of all deaths, excluding those from injuries, and hospitalizations that can be attributed to exposure to O3 and PM2.5. Exposure to these air pollutants can lead to chronic lung disease, heart attacks, strokes, and mortality. These adverse health effects contribute to economic costs through lost productivity, additional visits to doctors’ offices and hospitals, and burden on the health care system. They also influence overall well-being when individuals and families must deal with illness and death. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for the data sources and details on how the data were collected and how the indicator was calculated.
