First of all, technically the entire population can have access to this technology. One of the main cases is that you need to have a smart phone to enable the use of this technology. Theoretically, you can deploy this using Google Play store or App Store, and you can give everybody the capability to use this technology.
That said, if a person doesn't have a smart phone, they can also use certain features of this technology by going through a website, where they can see how the spread is happening in their own locality. If they're seeing some symptoms, they can easily go to that website, enter that information, and then do contact tracing. There are various ways we can securely provide that access to Canadians.
