Environment Canada says air quality has improved across most of Quebec and Ontario as changes in wind and rain ease the situation east of the Prairies, where wildfires continue to rage.

Smoke from the Canadian wildfires has triggered air quality warnings in several provinces and surrounding U.S. states. As of Friday, June 6, much of southern Ontario and southern Quebec, including Toronto, Ottawa and Montréal, have been placed under special air quality alerts.

Wildfires are still raging in Canada, where there have been dozens of active fires, and over 33,000 people have been forced to evacuate their homes.
