A hot and humid day is ahead, and Environment Canada has issued a heat warning for Toronto.

Expect temperatures to reach 32°C, with humidex values nearing 36°C to 40°C.

“Slightly cooler temperatures are expected on Saturday and Sunday before a possible rebound in temperatures early next week,” states the national weather agency.
