As much of Ontario sweltered through Canada Day, advocates warned that vulnerable populations are at the greatest risk from the extreme heat.
Orange heat warnings blanketed Environment Canada’s weather map, stretching from Windsor to Toronto to Ottawa.
Temperatures reached into the mid-30s in those areas.
“The hottest days are expected to be today and Thursday, with maximum temperatures of 34 to 37 degrees Celsius expected,” the national weather service said in its statement. “Minimum temperatures of 21 to 25 degrees Celsius will provide little relief from the heat.”
Environment Canada said the hot and humid conditions across the province could last through the weekend.
There were also heat warnings in place for northern Ontario, where places like Sault Ste. Marie, Timmins and Thunder Bay saw temperatures in the 30s, with humidex values near 40.
Keith Hambly, CEO of Fred Victor, a Toronto-based organization that provides shelter, housing, and support services across the city, said it was important for all community members to support one another.
