Heat Alerts and Extreme Heat Alerts

This dataset is no longer being maintained. To avoid duplication with the Heat Warnings issued by Environment and Climate Change Canada, the City of Toronto will no longer issue these warnings to the public as they are already communicated broadly. For historical/archived data, please see link below.

Information about Heat Alerts and Extreme Heat Alerts is updated daily. Alerts are issued by Toronto's Medical Officer of Health.

Toronto Public Health monitors the Heat Health Alert System every day from May 15 to September 30 each year, to alert those people most at risk of heat-related illness that hot weather conditions presently exist and to take appropriate precautions.
