Public weather alerting program

When severe weather threatens, Environment Canada, the authoritative source of Weather Alerts 24/7, is here for you, issuing special alerts that notify those in affected areas so that they can take steps to protect themselves and their property from harm. These public alert bulletins are issued through the media, as well as through the department’s Weatheradio service, and our Canada.ca/weather website.

Type of Alerts

The type of alert used depends on the severity and timing of the event.

New: Visit our Weather alerts page for weather alert type definitions and more. 

These alerts are updated regularly so that members of the public can stay on top of a developing situation and take the appropriate action.
