Alert Ready delivers critical and potentially life-saving alerts to Canadians through television, radio and LTE-connected and compatible wireless devices.
The Alert Ready system was developed with many partners, including federal, provincial and territorial emergency management officials, Environment and Climate Change Canada, Pelmorex, the broadcasting industry and wireless service providers.
Together, these partners work to ensure Canadians receive alerts immediately and know when to take action to stay safe.
The City of Markham will use an Alert Ready Notification if there is an emergency/disaster that impacts the City.
During an Alert Ready notification, you will hear a distinctive tone on television, radio or on your wireless device, please pay attention and take action right away.
Notice for the Visually and Hearing Impaired: Alternate formats of the alerts may be issued. However, not every alerting authority or device has the capability to produce or receive these formats. Broadcasters may use text-to-speech software to create an audio version of an alert message. Emergency alerts may be read to the recipient if your device supports this feature. The vibration feature that accompanies emergency alerts is available to alert Canadians. Please contact your wireless provider for more services which may be available to you.
