Obviously, any model the federal government would endorse or seek to help drive uptake toward would have to do a number of things. One of them is obviously that we'd be pushing for something that could be interoperable. The second is that it needs to conform to the guidance that's been provided by the chief privacy commissioners across all of the provinces and territories and the Office of the Privacy Commissioner of Canada, Daniel Therrien. One of those is that you need to be very clear up front with Canadians about what it is you're providing to them, what information is potentially taken into account and what control they have over that information.
I won't speak to the specifics of opt-in or opt-out, but I'll just say that, for any application, we'd need to make sure it conforms to the guidance that's been provided.
