The city of Toronto issued a heat alert Monday with temperatures forecast to reach a high of 33 C while a Humidex advisory remains in effect.
The hot muggy, conditions are expected to last for much of week.
“It is going to be sticky and temperatures are going to be above 30 C for most of the work week,” said CBC meteorologist Jay Scotland. “We will see relief toward the end of the week with thunderstorms.”
When a heat alert is issued, the city opens seven cooling centres which offer visitors an air-conditioned environment, along with water and light snacks.
