Air quality warnings are in effect for Manitoba as wildfire smoke continues to blanket much of the province. Environment Canada says Winnipeg and the city of Flin Flon in the province’s northwest are expected to see air quality health index ratings of over 10.

The smoke is expected to remain over the northern and central Plains of the United States for the next couple of days, according to meteorologists.

Smoke from wildfires in the Prairies is causing poor air quality and reduced visibility in the Hamilton-Niagara area and much of southern Ontario, Environment Canada says.
