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.
