Since 1994, Environment and Climate Change Canada has been producing daily air quality forecasts and timely smog warnings for Quebec. The Info-Smog program is available for 95% of Quebec's population. There are three categories of air quality: good, fair and poor. When air pollutant concentrations are likely to reach or actually reach levels harmful to the health and environment, Environment and Climate Change Canada issues a smog warning for the affected areas. The warning message is accompanied by advice on protecting your health and improving local air quality.
