No. Regulations mandated by the CRTC require all commercial, campus, community and Indigenous radio and television broadcasters, cable, satellite and IPTV providers, as well as wireless service providers to distribute emergency alerts.
There is no sign-up or opt-in required. Emergency alerts will be automatically sent through these broadcast channels, and to compatible wireless devices.
You cannot opt out of receiving threat-to-life emergency alerts. This is for your safety.
