August 29, 2014 – Ottawa-Gatineau – Canadian Radio-television and Telecommunications Commission (CRTC)

The Canadian Radio-television and Telecommunications Commission (CRTC) today acted to ensure that, in the event of an emergency situation, Canadians receive timely warnings over the radio and through their televisions. The CRTC is requiring the broadcasting industry to participate and relay emergency alert messages to Canadians.

Cable and satellite companies, radio stations, over-the-air television stations and video-on-demand services must begin issuing such messages by March 31, 2015. Campus, community-based and Native broadcasters have until March 31, 2016 to comply with this new requirement.

Emergency alert messages are issued by emergency management officials such as fire marshals, police officers and public health personnel to warn the public of dangers to life and property. For example, alerts could be issued to warn Canadians of Amber Alerts, tornadoes, forest fires, floods, meteors, water contamination and industrial disasters.

Currently, participation in the National Public Alerting System is voluntary.
