Location of Broadcast and Wireless Emergency Alert Distributors
Emergency alert distributors fall into the following categories:
- FM and AM radio stations
- over-the-air television stations
- subscription-based television service providersFootnote 1
- wireless providers
The map below shows the location of AM and FM radio stations, over-the-air television stations and subscription-based television service providers. It is considered current as of November 2019.
The map also includes a layer showing the aggregated distribution of LTE wireless coverage across Canada. It is current as of December 2019.
How data is gathered and why some providers may not be listed
Each year, the CRTC distributes a survey to update the data. These surveys are sent to AM and FM radio and over-the-air television stations and to subscription-based service providers that hold a broadcasting licence issued by the CRTC. Under certain conditions, no licence is required; in that case, the provider will not appear on the map.
In addition, if a provider started distributing emergency alerts after the survey cut-off date, it will not appear on the map.
