The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The International comparison of urban air quality indicators compare ambient levels (concentrations) of air pollutants in selected Canadian urban areas with levels in selected international urban areas. The indicators report the concentration of ground-level ozone (as the annual average of the daily maximum 8-hour average), fine particulate matter, sulphur dioxide and nitrogen dioxide (as the annual average of the daily 24-hour average) in ambient air. These indicators are intended to provide a general comparison of ambient levels of air pollutants in selected Canadian urban areas with those measured in other international urban areas. 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.
