By 11 a.m., Environment Canada reported that the temperature at Toronto Pearson International Airport stood at 32 C, which was the expected daily high. With the humidex, it felt more like 40 C.
CBC meteorologist Jay Scotland said that it was going to be more of the same in the afternoon.
"It is going to be very hot, very sticky, very hazy," Scotland said, reporting from Toronto's Woodbine Beach late Wednesday morning.
Scotland said the heat is going to continue for the rest of the work week.
"Hot, sticky today, no relief in sight until we get through into the weekend," he said.
8 pools open for extended hours
Not surprisingly, Toronto remains under an extreme heat alert, under which residents are advised to take steps to stay cool and also to check in on those who may be at risk of heat-related illness.
Eight city pools are open for extended hours as a result of the extreme heat and seven cooling centres across the city are available to residents who want to cool down.
The intense heat has left air conditioners running non-stop at many businesses, offices and private residences, which is putting great demands on the power grid.
Toronto Hydro spokesperson Tanya Bruckmueller said that businesses running air conditioners should not be keeping their front doors open while keeping the air conditioning cranked.
"A number of the large businesses are turning off non-essential loads, but we're also asking those businesses along the street not to cool the street — shut the door, please," she said in an interview with CBC News.
