Smog Warning

Issued at 22:26 Wednesday 22 February 2017

Atmospheric conditions could result in a deterioration in air quality.

High levels of pollutants are expected tonight into Thursday morning.


Smog especially affects asthmatic children and people with respiratory ailments or heart disease. It is therefore recommended that these individuals avoid intense physical activity outdoors until the smog warning is lifted.

In Quebec, wood heating is the main source of fine particles that contribute to smog during winter. This activity generates the largest number of these particulates, more than industrial activities and transportation.
