Environment Canada has issued a heat warning for parts of Southern Ontario.

Temperatures in Mississauga, Brampton, Oakville, Burlington, Milton, Halton Hills, and Hamilton are expected to be especially high this week, and as high as 40 degrees over the next three days.

From Tuesday to Thursday, temperatures are expected to be in the high 20’s during the day, but, with the humidity, they’re expected to climb to as high as 40 degrees.

Extreme heat affects everyone, but pregnant women, young children, the elderly, and people who work outside are especially susceptible to adverse effects.

Additionally, hot and humid air can cause the air quality to deteriorate and cause the Air Quality Health Index to approach the high-risk category.

On Friday, cooler, less-humid air is expected to reach these areas and bring temperatures down.

However, they could still reach 40 degrees on Friday during the day.
