Canada’s national public alerting system was tested in Ontario on Wednesday.
A test message and tone from Alert Ready was broadcast on television, radio and compatible wireless devices.
In Ontario, the test was scheduled for 12:55 p.m. ET but first appeared on wireless devices and aired on the radio. It then displayed on television screens at 12:57 p.m.
The system is also being tested across Canada. Test messages will be issued in every province and territory at specific times between late morning and early afternoon.
The system is typically tested in May and November to help ensure it works and so officials can practise issuing alerts for emergencies such as tornadoes, wildfires and Amber Alerts.
There is no option to opt out of the test or actual emergency alerts.
The Alert Ready system had issued nearly 900 emergency alerts this year in Canada as of Oct. 31.
