Toronto is about to experience its hottest day of the year, with the temperature expected to climb to 37°C on Tuesday, July 14. Combined with the humidity, it could feel as hot as 46°C, making it one of the most intense heat events of the summer.
Environment Canada’s heat warning remains in effect as a powerful stretch of hot, humid weather continues across the city. While Toronto has already endured several sweltering days this week, Tuesday is forecast to be the peak of the heat wave, with humidex values reaching between 45°C and 46°C.
The last time conditions came close was on Canada Day, when the humidex reached 44°C. Officials are also warning that deteriorating air quality could make spending extended periods outdoors even more uncomfortable. Residents are encouraged to limit strenuous outdoor activities during the hottest part of the day and watch for symptoms of heat-related illness, including dizziness, headaches, nausea, and fatigue.
If you’re looking for a place to cool down, Toronto has activated its heat relief network, with more than 500 air-conditioned spaces available across the city. Several civic centres, including Metro Hall and Scarborough Civic Centre, will remain open until 9:30 p.m. as designated cooling centres. Free bottle-filling stations are also available through mobile water trailers located at Nathan Phillips Square, Mel Lastman Square, East York Civic Centre, and Barbara Hall Park.
For anyone hoping to beat the heat outdoors, the city’s splash pads are operating daily from 9 a.m. to 9 p.m., while select outdoor pools will stay open later than usual for evening swims. Extended hours are available at Alex Duff Pool, Monarch Park Pool, Sunnyside Gus Ryder Pool, and North Toronto Memorial Pool, among others.
Whether you’re heading to a pool, staying indoors, or simply running errands, it’s a good idea to drink plenty of water, wear sunscreen, avoid prolonged sun exposure, and check in on friends, family, and neighbours who may be more vulnerable to extreme heat.
The City of Toronto has also published a complete list of cooling centres and pools with extended hours for anyone needing relief from the soaring temperatures.
