Step outside and you'll probably smell it—smoke has been a major issue across much of Eastern Canada this weekend. Montreal and Toronto made the list for the top-five major global cities with the worst air quality on Sunday. The cities ranked fourth and fifth, respectively, with air quality values in the “unhealthy for sensitive groups” range.

Wildfire smoke from the Prairies prompted special air quality statements and warnings across the country Saturday.

An elevated flooding risk persists on Sunday for some parts of the Southeast as Alabama, Georgia and the Florida Panhandle brace for heavy rainfall.
