The Canadian Emergency Alert System was tested again on November 25, 2020, to make sure the emergency alerts are effectively reaching cellphones, radio, and TV stations. Past tests have revealed technical issues that led to notification delays. Authorities are still working to make sure the system is compatible with different networks and cell towers. The Alert Ready system has been used more than 170 times since it was launched on January 1, 2020, and its notifications can be sent by emergency management officials, warning of severe weather or when there is an imminent threat to life. The alerts have been valuable in warning the public and have also prompted the public to provide tips. The Ontario Provincial Police have also begun using Alert Ready to keep residents safe and notify the public about AMBER Alerts. The system has been used four times in Ontario since July 2020.
