Air Quality Health Index

Source: Environment Canada, 2017

In June 2015, in partnership with Environment Canada, the Ontario Ministry of the Environment and Climate Change adopted the National Air Quality Health Index to report air quality in Ontario.

The Air Quality Health Index is a tool designed to communicate the health risk for students vulnerable to the effects of air pollution (students with diabetes, heart and lung disease) as well as for the general student body. It forecasts local air quality for the current day and the next day. It is designed to assist in health-related decisions. The index does not measure the effects of odour, pollen, dust, heat, or humidity on health.
