Emergency Alert Messages and the National Public Alerting System

In 2014, the CRTC required that FM radio, AM radio and over-the-air (OTA) television stations, as well as subscription-based broadcasting service providersFootnote 1, to participate in the National Public Alerting System (NPAS).

Since April 6, 2018, the CRTC requires that all wireless service providers participate in the NPAS and begin distribution of wireless public emergency alerts on their long-term evolution (LTE) networks.

Emergency alert messages are issued by public officialsFootnote 2 who are designated by the federal government or your province or territory to warn the public of imminent or unfolding hazards to life and property (e.g., fire, natural disasters, biological threats, hazardous materials, environmental disasters, civil emergencies). These officials are also responsible for issuing scheduled test messages.

Each year, during Emergency Preparedness Week in May, wireless service providers and broadcasters will distribute a test alert. Read more about alert types and testing at Alert Ready.

Wireless Public Alerting

To be able to receive wireless alerts, your mobile device must be an LTE device like a smartphone, compatible with wireless public alerting, and connected to an LTE cellular network at the time the emergency alert is issued.

Emergency alerts are issued to a defined geographic area, such that only people in the defined area will receive the emergency alerts. If you are travelling in another province when an alert is issued, your compatible wireless device will receive the alert, provided your phone is powered on and connected to the LTE cellular network. There is no need to enable the location services on your wireless device to receive alerts.

When an alert is issued, you will hear the same alert tone on your mobile devices as you currently do while listening to the radio or watching television. The alert will also trigger a unique vibration cadence.

To know more about the compatible wireless devices offered by your wireless service provider, visit Alert Ready.

Important Notes

There might be radio or TV stations or subscription service providers broadcasting or distributing emergency alert messages that aren’t on our map or that do not appear in the list. Why?

There are two possible reasons.

First, the map and list are created by using data collected from CRTC annual surveys that are issued to FM radio, AM radio and over-the-air (OTA) television stations, as well as subscription-based broadcasting service providers. Recipients are required to submit the surveys to the CRTC no later than November 30 of each year. The data contained in the list and map were collected as part of the November 30, 2016 annual surveys. Any station or service provider that started broadcasting or distributing emergency alerts after November 30, 2016 may not appear on the map and in the list.

Second, the surveys were only sent to FM radio, AM radio and over-the-air (OTA) television stations and subscription-based broadcasting 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 therefore do not appear in the map or list.
