Guide to Environment Canada's Air Quality Health Index (AQHI) Forecasts
The Air Quality Health Index (AQHI) was developed, in partnership with Health Canada, the provinces and other local partners. It is a public information tool that provides daily forecasts about air quality levels. It lists, on a scale from one to 10, the health risks associated with certain air pollutants known to be harmful to human health. Using the scale, Canadians can be better prepared to deal with air pollution and take the appropriate steps to limit their exposure.
The AQHI is forecasted twice daily for certain locations across Canada; it also predicts maximum AQHI values over the next two days, and provides other related health messages. To get the latest AQHI forecast for a specific location, click on one of our regional maps.
