Toronto's heat warning has been extended through Saturday, meaning residents will endure at least another full day of dangerous temperatures and humidity.
Environment Canada originally expected the warning to end Friday but extended it after parts of southern Ontario, including Toronto Pearson Airport, set new Canada Day temperature records. Humidex values have climbed into the 40s.
The City of Toronto says its Heat Relief Strategy remains in effect. More than 500 Cool Spaces—including libraries, community centres, and civic centres—are open across the city. Outdoor pools, splash pads, and supervised beaches remain open. Four mobile drinking water stations are stationed at Nathan Phillips Square, Mel Lastman Square, East York Civic Centre, and Barbara Hall Park. Nathan Phillips Square's station will stay throughout the FIFA World Cup.
At FIFA Fan Festival Toronto, the city has set up misting stations, shaded cooling areas near Fort York, free drinking water, and on-site medical staff. Toronto Public Health reminds residents to drink water regularly, wear lightweight clothing, and check on older adults and vulnerable neighbours. Heat exhaustion symptoms include dizziness, nausea, headache, confusion, and extreme fatigue; anyone experiencing severe symptoms should seek immediate medical attention.
