If you hear the Alert Ready siren this week, don't call 911. Most provinces and territories will receive a nationwide test of the Alert Ready emergency-alert system on Wednesday, May 6, 2026, with broadcasts on television, radio and compatible wireless devices. Officials' corrected release notes Ontario's test time has been adjusted to 1:55 PM EDT. The test will start with the Canadian Alert Attention Signal and will clearly say it's a test, and officials say no action is required. Before the test, check your device settings and software and consult the Alert Ready website or your provincial emergency-management page for the confirmed schedule and compatibility details.

If you are wondering whether your phone, TV or radio will blare the Alert Ready tone this week, here is what to expect and what to do. Emergency Preparedness Week is the backdrop for the exercise, and the national test is meant to confirm the system works and to help people recognise the alert signal in a real emergency. The corrected schedule published by officials lists most provinces and territories taking part on May 6, with Ontario's test time corrected to 1:55 PM EDT.

Where and when the test will play

Look, the corrected timetable gives test times in local time for each participating province and territory. Alberta, British Columbia, Manitoba, Nova Scotia, Nunavut, Saskatchewan, Yukon and several other jurisdictions are scheduled for 1:55 PM in their respective zones on May 6. New Brunswick is listed at 10:55 AM ADT, Newfoundland and Labrador at 9:55 AM NDT, Prince Edward Island at 12:55 PM ADT, and the Northwest Territories at 9:55 AM MDT. Quebec isn't scheduled to receive a test on May 6 under the published timetable.

Ontario’s test time was corrected to 1:55 PM EDT. Media accounts and provincial bulletins repeat that most jurisdictions will receive the test, and they describe the same distribution channels of television, radio and compatible cellphones.

How the alert will arrive and who might not get it

The test will begin with the Canadian Alert Attention Signal, followed by a spoken message that will state clearly it's a test and that no action is required. It will be sent through conventional broadcasters and through compatible wireless devices using LTE or 5G networks.

Not every mobile device will receive the alert. Device compatibility, network connectivity, cell tower coverage and a device’s settings or software configuration can all affect whether an individual phone gets the message.

Mastheads

Officials note there's no opt-out option for Alert Ready alerts, including tests, because the system is designed to warn the public of imminent threats to life.

Some wireless carriers may conduct silent tests, which means a test message could arrive without sound depending on your phone settings. People who use emergency notification apps might also receive the test through those apps. After the exercise, some participating jurisdictions may follow up with a link to an online survey asking for feedback about the alerting experience in that area.

Why the test happens and practical steps for you

Government and emergency-management statements make the purpose plain. The test aims to increase public awareness of the alert system, to encourage household conversations about emergency preparedness, to validate reliability across broadcasters and wireless providers, and to give emergency-management organisations practice issuing real-time alerts. The Alert Ready system is routinely tested in May and November to keep the network functioning and familiar to the public.

By the end of April, the system had issued multiple real alerts in Canada covering events such as AMBER Alerts, tornado warnings and other immediate threats. That history is part of why officials say the public shouldn't be given the option to opt out. The priority is warning people when there's a real and immediate danger.

There are a few concrete steps you can take this week. Check your phone’s notification settings and make sure system notifications for emergency alerts are enabled. Install any pending software updates for your device, because compatibility hinges on both hardware and software. If you rely on an emergency notification app, make sure it's updated and that its alerts are enabled. Finally, consult the Alert Ready website or your provincial emergency-management page for the official compatibility list and the confirmed schedule for your area.

Right now, officials also ask residents not to call 911 for information about the test. Non-emergency calls can delay response for people facing actual crises. If you want to give feedback after the test, watch for a survey link from your local jurisdiction.

One outstanding discrepancy to check locally

There is a disagreement in the public reporting about Saskatchewan’s participation. The corrected official schedule lists Saskatchewan at 1:55 PM CST as a participating jurisdiction on May 6. Several media reports, however, say tests will be issued in nearly every province and territory except Quebec and Saskatchewan, effectively excluding Saskatchewan from the May 6 test. Another report lists all provinces and territories except Quebec, which would include Saskatchewan.

If you live in Saskatchewan, or if you want absolute certainty about any local timing, check with your provincial emergency-management authority or the Alert Ready website for the definitive status in your area. Local emergency-management pages will carry the confirmed timetable and any last-minute changes.
