Air Quality Forecasts and Advisories

An air quality forecast, issued daily, is a one to two day prediction of air quality conditions. The air quality is expressed using the Air Quality Index (AQI). The air quality forecasting program works as a partnership between Environment Canada and the provinces.

Air Quality advisories are issued when the air pollution levels exceed national standards. They are issued in partnership with provincial and municipal environment and health authorities and contain advice on action that can be taken to protect the health of Canadians and the environment.

Current Air Quality

Updated hourly, the current air quality gives the level of the various air pollutants. In most provinces it is show using an air quality index or AQI.

Air Quality Maps

Air quality maps are produced at the Canadian Meteorological Centre, Environment Canada’s super computing facility in Montréal. These maps show computer generated air quality forecast conditions that play an important role in the air quality we experience.
