Wireless Public Alerting explained
Wireless Public Alerting (WPA) description and device compatibility list
What is Wireless Public Alerting/Alert Ready?
is a service designed to deliver critical and potentially life-saving emergency alert messages to Canadians over radio, TV and now wireless smartphones.
The Alert Ready system was developed in partnership with federal, provincial and territorial emergency management officials, Pelmorex Corp., the broadcast industry and wireless service providers including TELUS to ensure you receive emergency alerts immediately and know when to take action to keep you and your family safe.
TELUS and all Canadian wireless service providers are required to broadcast emergency alerts received from alerting authorities directly to consumers’using Cell Broadcast distribution.
Wireless service providers will only receive and broadcast alerts that are issued for.
Emergency alerts intended for wireless devices are issued to a defined geographic area, which can be as small as a few city blocks, so that only people in the defined area receive the emergency alerts. The defined area is selected by the alerting authorities. Compatible wireless devices in the targeted area, including devices that are roaming, will receive the emergency alerts within seconds of alert issuance, provided the devices are powered on and connected to the LTE cellular network. If you are travelling outside of Canada to a country that has a functional wireless alerting service, you may receive alerts issued to the geographic location you are in.
NOTE: As mandated by the CRTC, you cannot opt out of receiving threat-to-life emergency alerts.
What do Wireless Public Alerts look like?
While the alerts may look like text messages, they are not text messages and are not billed like text messages nor do they count towards data usage.
Emergency alerts begin with a distinct sound, known as theand may also cause the device to vibrate.
On compatible wireless devices, the emergency alert will display an EMERGENCY ALERT/ALERTE D’URGENCE banner with information describing the situation, instructions on what actions to take and where to learn more. At the top of each emergency alert, the issuing government agency will be clearly indicated.
As a general rule, emergency alerts will only be issued once. In the event that the issuing government has an update to the original alert, you will receive updated alert messages.
Note: You will occasionally receive a test alert that allows the government to ensure the system is working as expected. The test alert text will clearly indicate that it is a test alert.
If you are a person with a sight or hearing disability, alternate formats of the emergency alert can be issued. Emergency alerts may be read to the recipient if their device supports this accessibility feature and the vibration feature that accompanies emergency alerts sent to wireless devices will help make hearing impaired aware of alerts.
