Environment Canada has issued orange and yellow weather warnings as a prolonged heat wave moves across much of Ontario, including Toronto and Ottawa, starting today.
Daytime highs are expected to reach 33 C, with humidex values making it feel like 42 C. The hot, humid weather could last until Friday or even into the weekend, with northern Ontario also expected to see dangerous heat.
Heat warnings are also in effect for parts of Quebec, including Montreal. Officials are urging people to stay hydrated, avoid too much time in the sun, and check on older adults, neighbours, and others at higher risk of heat-related illness.
