Air Quality in Québec

In Quebec, a series of programs have been put forward to measure air pollutants. The following programs provide you with information on the quality of the air you breathe.

Info-SMOG

Info-SMOG is an air quality forecasting program which includes a public alert component. In summer, the program covers all of southwestern Quebec, while in winter, it concentrates on the Greater Montreal area.

National Air Pollution Surveillance Network

The National Air Pollution Surveillance (NAPS) Network, a joint federal-provincial program, has been keeping an eye on pollution in Canada for almost 30 years. This program measures conventional pollutants present in the air such as sulfur dioxide (SO₂), ground-level ozone (O₃), nitrogen dioxide (NO₂) , total reduced sulfur (TRS), carbon monoxide (CO), fine particles (PM_2.5), and several other substances.

Ministère du Développement durable, de l’Environnement et des Parcs - Québec

The Ministère du Développement durable, de l’Environnement et des Parcs du Québec also has stations throughout Quebec for measuring air pollutants and finding out the level of exposure of the population of Quebec to air pollution. The ministry's network covers the entire province except for the island of Montreal, responsibility for which is delegated to the City of Montreal .

To learn about your exposure to air pollution, consult the Ministère du Développement durable, de l’Environnement et des Parcs du Québec's website.

The City of Montreal Network

The City of Montreal maintains a network of air quality measuring stations on the island of Montreal. Most of these stations are part of the National Air Pollution Surveillance Network. The City of Montreal publishes its results online as an air quality index. We invite you to follow the Montreal air quality index (French only)
