Alberta Emergency Alert

Alberta Emergency Alert (AEA) was a public warning system in Alberta. The system was implemented in October 2011, replacing the former Alberta Emergency Public Warning System (EPWS). Based on Common Alerting Protocol (CAP), alerts were disseminated through various media outlets including television and radio, internet, social media mobile apps, and cell broadcast.

In March 2015, per an order by the CRTC, it became mandatory for all radio and television broadcasters to participate in an emergency alert system such as AEA. In April 2018, it also became mandatory for all wireless service providers to participate. In 2023, AEA was decommissioned by the Alberta government as an autonomous system, in favor of migrating all participants to the national Alert Ready system operated by Pelmorex.
