Roughly 17,000 residents in the Canadian province of Manitoba have been evacuated because of nearly two dozen active wildfires, officials said Saturday.

Wildfires in Canada have forced thousands of residents to evacuate in three provinces, impacting air quality in the U.S. — and smoke from the deadly fires has even blown across the Atlantic and reached the U.

Wildfire smoke is spreading throughout Central Canada and into parts of the U.S., with air quality warnings being issued in both countries.
