Emergency Alert Messages and the National Public Alerting System (NPAS)

NEW! In April 2017, the Commission directed wireless service providers to implement a wireless public alerting system on their networks: Wireless service providers must join the National Public Alerting System.

Emergency alert messages are currently distributed to Canadians over the broadcasting system (TV and radio). They are issued by public officialsFootnote 1 who are designated by your province or territory to warn the public of imminent or unfolding hazards to life (e.g., fire, natural disasters, biological threats, hazardous materials, environmental disasters, civil emergencies). These officials are also responsible for issuing scheduled test messages. Read more about alert types at AlertReady.

In 2014, the CRTC required that FM radio, AM radio and over-the-air (OTA) television stations, as well as subscription-based service providersFootnote 2  broadcast and distribute emergency alert messages. The system used to deliver these alert messages is known as the National Public Alerting System (NPAS). Read more about the NPAS on publicsafety.gc.ca


The table of the subscription-based service providers that distribute emergency alert messages.

This table lists the subscription-based service providers that distribute emergency alert. These service providers offer multiple services that are available across the country. If you subscribe to one or more of the services in the table, you should be receiving emergency alert messages. If you require more details, please contact your service provider.

Important Notes

There might be stations or subscription service providers broadcasting or distributing emergency alert messages that aren’t on our map or listed in the table. Why?

There are two possible reasons.

First, we created the map and table using data collected from two CRTC surveys that were issued to FM radio, AM radio and over-the-air (OTA) television stations, as well as subscription-based service providers. Data from the first survey was received on March 31, 2015 and from the second on December 31, 2015. Any station or service provider that started broadcasting or distributing emergency alerts after December 31, 2015 do not appear on the map.

Second, the surveys were only sent to FM radio, AM radio and over-the-air (OTA) television stations and subscription-based service providers holding a broadcasting licence from the CRTC. Some stations or service providers, under very specific conditions, are not required to have a licence and so they do not appear in the map or table.
