Environment and Climate Change Canada (ECCC) 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 or higher.

WeatherCAN

Environment and Climate Change Canada (ECCC) has launched a new mobile app called WeatherCAN. The app provides Canadians with access to reliable weather information directly at the tip of their fingers. Download WeatherCAN directly from the ECCC website.

Toronto’s Hot Weather Response Framework

The City of Toronto Hot Weather Response Framework 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 framework is to provide education and services to vulnerable groups at increased risk for heat-related illnesses.

Heat Warnings in 2019

Following direction of City Council and the Board of Health, a City-wide Heat Relief Strategy is being implemented beginning in May 2019. This approach will integrate the services and responses to heat provided by several divisions.

To avoid duplication with the Heat Warnings issued by Environment and Climate Change Canada, Toronto Public Health will no longer issue these warnings to the public as they are already communicated broadly.
