We’ve both installed the COVID Alert app, even though it’s not fully functional in our province (so far it’s just Ontario). We can’t report a COVID diagnosis, but we can get notified if someone from Ontario we’ve come into contact with does report a positive COVID test result. Since we live near the Ontario-Quebec border, and sometimes have to cross into Ontario for errands and such, there’s already some value in installing it.
It can’t run on older phones (on the Apple side, older than an iPhone 6S or first-gen SE) because of hardware limitations, I believe. It makes use of the Apple/Google API, which has strong privacy protections: the only things it shares with the server or with other phones are anonymous tokens. The privacy protections are such that Michael Geist is comfortable installing it, which is something.
It’s in that context that I have to look really sideways at a CBC article that suggests that some people could be identified by the COVID Alert app.
