The test alerts scheduled for May 9th were successfully processed by the National Alert Aggregation and Dissemination System (NAAD System), part of the Alert Ready system. Managed by Pelmorex, the NAAD System delivers public alert messages issued by authorized government agencies to TV/radio/cable/satellite companies, and now, wireless service providers. It is then the responsibility of these Last Mile Distributors (LMDs) to deliver alert messages directly to Canadians.
Wireless service providers are working to identify any issues with compatible handsets. It is important to note that not all wireless devices are compatible and able to receive messages from Alert Ready. A device needs to be connected to an LTE network. Compatibility depends on many factors, including the handset and the software version on the device. You can check compatibility here, or with your carrier.
The intent of these tests is to validate all components of the Alert Ready system before an actual emergency. By running these tests, all Alert Ready partners get valuable information and feedback that will help improve the system. Canadians can feel confident the alerts will continue to be delivered via TV and radio.
