Most Canadians consider the Labour Day weekend the unofficial end to summer, but in southern Ontario, temperatures continue to soar.
A humidex advisory is in place for parts of southwestern Ontario. The City of Toronto also issued a heat alert Friday morning with temperatures set to reach 32 degrees.
"Factor in the humidity and it will be feeling closer to 40," says Gerald Cheng, a meteorologist at The Weather Network.
Health officials are urging people to keep cool by drinking water and staying hydrated.
“You want to try and stay out of the sun as much as possible as well,” says Tanya Elliot with the Canadian Red Cross. “Avoid any strenuous activity particularly between the hottest part of the day, which is around 11am to 4pm.”
During a heat alert, the city also encourages people to check on relatives or friends who are at a greater risk of suffering from heat-related illnesses.
