A smog warning is in effect for parts of southern Quebec, where high levels of pollutants are expected to last until Wednesday morning.
Environment Canada issued the notice on Tuesday for several areas, including Montreal, Vaudreuil-Soulanges, Lanaudière and Lachute.
“Smoke plumes are moving into Southwestern Quebec from several wildfires in Northwestern Ontario,” the weather agency said. “Air quality may deteriorate at ground level.”

Children with asthma and people with respiratory ailments or heart disease are most at risk during periods of smog, according to Environment Canada.
As a result, they should avoid high-intensity physical activities outside until the warning is lifted.
The weather agency says residents can help improve air quality by opting for public transit instead of driving.
For those who are driving, reducing speed on the road and not letting cars idle also help during periods of smog.
