A man walks along the St. Lawrence River on Friday, as smoke from the wildfires in the Canadian Prairies is causing poor air quality and reduced visibility in the Greater Montreal region.

Wildfires in Western Canada have forced thousands of people to flee their homes and the heavy smoke has prompted more than 400 air quality warnings and advisories in seven provinces and one territory as of Friday.

Toronto, Ottawa, Montreal and Quebec City are under advisories for the first time this year. Smoke from the more than 200 wildfires being battled in Canada has also made it to the United States and prompted an air quality advisory in New York City and as far as the midwest earlier this week.
