Limit time outdoors,” Environment and Climate Change Canada advises everyone as it issues special air-quality advisory for large parts of the province, including Montreal.

Wildfire smoke in Manitoba could be even more toxic than usual and more research needs to be done on the pollutants being released into the air, according to scientists.
