Toronto Heat Relief Strategy expands Cool Spaces, water access and outreach during extreme summer heat
TORONTO — The City of Toronto has officially activated its annual Heat Relief Strategy as officials warn that hotter and longer summers are increasing health risks across the city.
Toronto Medical Officer of Health Dr. Michelle Murti and Toronto Emergency Management Executive Director Joanna Beaven-Desjardins announced Wednesday that the strategy is now in effect through September 30.
The City says the initiative is designed to help residents stay safe during extreme heat events by expanding access to cooling spaces, drinking water and emergency outreach services.
