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, including AEA.

In 2023, AEA was decommissioned by the Alberta government, in favor of migrating all participants to the national Alert Ready system operated by Pelmorex.

[6] Effective March 31, 2015 for television and radio broadcasters, and April 6, 2018 for LTE wireless networks, carriage of AEA "Critical" messages became mandatory under CRTC rules regarding the implementation of Alert Ready, a national emergency notification system developed by Pelmorex that uses a modified version of the Common Alerting Protocol (CAP) also used by AEA.

[7][8] On April 30, 2022, the Alberta Emergency Management Agency (AEMA) announced that the AEA infrastructure would be decommissioned by March 2023, in favour of fully adopting NAAD; broadcasters would be required to reprogram their CAP decoders to point to the national system.

[14][15] In Alberta, AEMA employs a "decentralized" model for operating emergency alerts, under which local authorities have direct access to the system.
