second heat event to hit Toronto this week
Environment Canada has issued a heat warning for Toronto and southern Ontario as temperatures are expected to reach the mid-30s with high humidex values. Residents are advised to take precautions against heat-related illnesses, and the city has activated its heat relief strategy, including mobile water stations.
Why it matters
Extreme heat events pose significant public health risks, particularly for vulnerable populations, necessitating coordinated municipal and environmental responses.
Toronto will bake under another heat event this week with daytime highs in the mid-30s and humidex values as high as 45.
As a result, Environment Canada has issued a yellow heat warning for the city and the rest of southern Ontario.
The heat event is set to begin on Monday and will last until either Wednesday or Thursday evening, Environment Canada said.
“Tuesday will mark the peak of this heat event. Maximum temperatures are expected to reach near 36 C in some areas,” the national weather agency noted in its advisory.
During the heat event, Ontario residents could see humidex values of 38 to 45.
There will be little relief from the heat, as temperatures won’t dip to lows below 20 C for the duration of the heat wave.
