Weather warning issued for much of Ontario due to ‘dangerously’ hot, humid conditions
A heat warning has been issued for the Greater Toronto Area and many other southern, eastern and northern Ontario regions as a ‘prolonged’ stretch of hot, humid weather is set to move in.
According to the warning issued by Environment and Climate Change Canada meteorologists Sunday afternoon, the extended “heat event” will begin on Monday.
“Dangerously hot and humid conditions are expected through most of the week,” the warning said.

“Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high-risk category.”
The warning said daytime temperature highs are forecast to be between 30 and 35 C. If humidex values are factored in, it could feel like it’s between 40 and 45 C.
Meteorologists added there will be “little relief” during the night with temperature lows forecast to be between 20 and 23 C, and humidex values between 26 and 30 C.
A map of the affected regions under the heat warning included communities such as Windsor, London, Kitchener-Waterloo, Peterborough, Kingston, Cornwall, Barrie, Huntsville, Algonquin Park, Sudbury, Timmins, Cochrane, Moosonee and Fort Severn.
