This is based on the Apple/Google API initiative. Now if only we can get the provinces onboard with this. One of the things about Canada is that the provinces are largely responsible for funding and delivering health so that federal government can not mandate that the various provincial governments adopt this. A couple of provinces have their own applications but none of these apps have approval to use the Apple/Google APIs so hopefully they'll drop them and use the Canadian one instead. It makes more sense to have a single app for the whole country.
