Alberta Emergency Alert

Alberta Emergency Alert (AEA) is a public warning system in Alberta that warns the public on impending or occurring emergencies affecting an area. The system was implemented in October 2011, replacing the former Alberta Emergency Public Warning System. Alerts are disseminated through various media outlets including television and radio,[1] internet,[2] social media [3][4] mobile apps, and cell broadcast.

This article is about the alert system in Alberta since 2011. For former alert method in Alberta, see Emergency Public Warning System.

Alerts are set into two stages; an "Information Alert", in which the public is advised to be prepared for potentially life-threatening emergencies. Information Alerts do not interrupt TV and radio broadcast. A "Critical Alert" in which potentially life-threatening danger is imminent or present such as a tornado touchdown. TV and radio stations in Alberta must transmit "Critical" messages from Alberta Emergency Alert. The system also broadcasts alerts in the event of an AMBER alert.

Unlike the previous system (where the alerts were read on-air by a recorded voice), alerts are read using a text-to-speech system. Initially, the quality of its voice was criticized, with viewers considering it unclear and prone to mispronouncing the names of locations.[5] In 2013, a new, male voice was implemented, which was programmed to have clearer pronunciations of various terms and place names.[6]

Effective March 31, 2015 for television and radio broadcasters, and April 6, 2018 for LTE wireless networks, carriage of AEA "Critical" messages is mandatory under CRTC rules regarding the implementation of Alert Ready, a national emergency notification system developed by Pelmorex that also uses Common Alerting Protocol. As AEA has compatibility with Alert Ready's format and distribution system (besides minor differences in AEA's XML schema for Common Alerting Protocol), the CRTC has considered participation in AEA to sufficiently in compliance with the national alerting mandate.[7][8]
