The Government of Canada has been exploring a number of options, and we are obviously aware that one of the critical factors that determine the success of exposure notification applications is uptake and the degree to which there is widespread adoption.
One of the ways to fuel that adoption is to allow for commonality and jurisdictional interoperability. That's been one of the key priorities as we've worked through this file. We continue to work with provinces and territories to arrive at a possible solution that would provide that level of interoperability and fuel that uptake.
As you note, with the absence of sufficient uptake, you actually run two risks. One is that you potentially fuel false confidence from folks who don't believe they've necessarily been exposed, but that's actually a function of the fact that they're not coming into contact with other people who have downloaded the application. The other is that we know there's interjurisdictional and interprovincial travel, and we need to ensure interoperability across those that recognizes the realities of Canadians who are crossing interprovincial borders.
We continue to work toward that interoperability goal.
