Cool Spaces
To help ensure the safety and wellbeing of all residents during the summer season, the City of Toronto activates its Heat Relief Strategy from May 15 to September 30 each year.
A key part of the strategy is the Heat Relief Network where people can access Cool Spaces across the city including libraries, community centres and pools, to seek relief from summer heat.
Yesterday, the City’s 10 wading pools and 10 outdoor pools opened ahead of schedule to provide residents with more options for staying cool during hot weather. For more information, including pool hours, visit the City’s Swimming & Water Play webpage.
An interactive map of all Cool Spaces is available on the City’s website.
