Environment & Climate Change Canada issues Heat Warnings across Canada. A Heat Warning is issued for southern Ontario (including Toronto) when there is a forecast of two or more consecutive days with daytime maximum temperatures of 31°C or warmer, together with nighttime minimum temperatures of 20°C or warmer or when there is a forecast of two or more consecutive days with humidex values expected to reach 40°C or higher.
Check Environment & Climate Change Canada website for information on your local forecast and weather alerts or download their mobile app, WeatherCAN, which provides weather alert notifications in your area, as well as in your saved locations.
The City of Toronto’s Heat Relief Strategy is a protocol for hot weather response that aims to reduce the incidence of heat-related illness and death in Toronto due to extreme heat. The main focus of the strategy is to provide education and services to vulnerable groups at increased risk for heat-related illnesses.
The City’s Heat Relief Network features cool spaces that are open during and beyond Heat Warnings and others open only during Heat Warnings. It includes pools, wading pools, splash pads and community centres.
The City’s Streets to Homes outreach team does wellness checks for clients who live outdoors.
