Wildfires unleash thousands of evacuations in Canada and ‘unhealthy’ air quality in these U.S. states

More than 25,000 residents in three provinces have been evacuated as dozens of wildfires remained active Sunday and diminished air quality in parts of Canada and the U.S., according to officials.

Most of the evacuated residents were from Manitoba, which declared a state of emergency last week. About 17,000 people there were evacuated by Saturday along with 1,300 in Alberta. About 8,000 people in Saskatchewan had been relocated as leaders there warned the number could climb.
