A heat warning has been issued for Toronto and much of southern Ontario this weekend, with temperatures set to feel like 40 with the humidity.
Environment Canada issued the alert Friday afternoon and said daytime highs of 31 C to 33 C are expected on both Saturday and Sunday.
“Take action to protect yourself and others – extreme heat can affect everyone’s health,” the national weather agency said in the alert.
Officials say there will be “little relief” overnight Saturday, when the temperature will only drop to between 21 C and 25 C.
The heat is expected to break Sunday night. Environment Canada urged the public to stay hydrated, use air conditioning if available, limit direct exposure to the sun and limit outdoor activities to the coolest parts of the day.
