Environment Canada has issued a Heat Warning for Toronto ahead of several days where feels-like temperatures are expected to reach 40°C.

According to the weather agency, a “hot and humid tropical air mass” will start impacting the city today, and the heat and humidity will last until at least Monday.

Friday and Saturday are expected to be sunny, with Sunday showing a chance of showers and Monday calling for clouds.

Afternoon temperatures will reportedly reach the low to mid thirties, with humidex values reaching 40°C each afternoon. Temperatures overnight will remain in the low to mid twenties, providing little relief from the heat.

Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category.

Extreme heat affects everyone, and the risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.

Symptoms of heat illness include dizziness/fainting; nausea/vomiting; rapid breathing and heartbeat; extreme thirst; and decreased urination with unusually dark urine.

To preserve their safety, people or pets should never be left inside a parked vehicle. Eating light, cool meals during the heat is also recommended by Environment Canada.

As a safety measure, starting today, the City of Toronto will open Emergency Cooling Centres for the duration of the Heat Warning — these spaces are available to residents who do not have access to a cool space and cannot keep cool in their home or outdoors.

Slightly cooler and less humid conditions may arrive on Tuesday, Environment Canada says.
