Together, let's limit the spread of COVID-19 and prevent future outbreaks.
COVID Alert helps us break the cycle of infection. The app can let people know of possible exposures before any symptoms appear.
That way, we can take care of ourselves and protect our communities.
Protect yourself. Protect others. Get notified.

Is it voluntary?
Use of the COVID Alert app is voluntary. We are hoping Canadians will embrace this tool to help slow the spread of COVID-19 and help prevent future outbreaks. The app will be most effective in helping limit the spread of COVID-19 when a majority of Canadians use it.
Starting in Ontario
During this first phase, health authorities in Ontario will begin distributing one-time keys to people who test positive for the virus. When the key is entered in to the app, COVID Alert will notify other users who may have come in close contact with that person. The Government of Canada is working with the other provinces and territories to make this available across Canada.
Even outside Ontario, it's still helpful to download COVID Alert. That way, when people in your area are able to report a positive test result, you'll be notified if you had close contact with them (at least 15 minutes and less than 2 metres apart).
Why do I need to turn on location settings?
For the app to work, Android users must turn on location settings. However, no location information is stored or transmitted. Apple users do not need to change their settings for the app to work. Your phone does not transmit your location to other phones, to Apple or Google, or to any government database.
In order to protect against cyber attacks, Canadian servers will store your IP address for three months (and in the case of an identified security incident, up to 2 years). This is a standard part of how the Government of Canada protects online systems from cybersecurity threats.
What do I do if I receive a notification?
If you receive a notification saying that you have been exposed to COVID-19 in the last 14 days, the app will say that you are at risk of being infected and direct you to your provincial health authority for guidance.
Anyone who believes they may have been exposed to COVID-19, whether notified through the app or otherwise, should follow the guidance from their local public health authority.
