The City of Toronto’s medical officer of health has issued a heat alert for Toronto. It will be in effect until further notice..!

During a heat alert, the public is encouraged check on family, friends and neighbours, especially isolated adults and seniors, who are at greater risk of suffering from heat-related illness. Also, you should not leave seniors, children or pets unattended in a car.

This is the fifth heat alert of the year so far covering seven days: May 28, June 19, June 28-30, July 3 and now, July 12. The city has issued two extreme heat alerts covering five days: June 20-21 and July 4-6.

Meanwhile, Environment Canada confirmed the last 12 months have been the warmest in Toronto in record history.

So far in July, the city had four days of temperatures above 30 C.

And,  it’s been a season of broken records. Toronto had a five-day record warm stretch in March with recording-breaking temperatures.

March record highs were:

  • March 18 – 19.9 C
  • March 19 – 22.8 C
  • March 20 – 21.9 C
  • March 21 – 23.3 C
  • March 22 – 26 C


The city also had below-average rainfall for March, April and May, and above-average rain in June — but not enough to make up for the early spring drought.

Only 15.6 millimetres of ran fell in March, with 42.4 and 44.4 millimetres in April and May, respectively.

How are you dealing with the heat?  Any tips to pass on, for those struggling with it?
