Mr. Chair, I would say there's obviously an opportunity cost to everything—if you do more of one thing, you're going to have to do less of another—but I don't characterize this as an issue of resources from the CRA's perspective. We were given the resources to carry out a compliance program consistent with what you would see in international best practices.
Again, there's just a bit of confusion around the $15.5 billion. That's an estimate of what might potentially be out there, based on GST monthly data from the pandemic. I'm just not sure that it's worthwhile investigating all of those cases, because when we have looked at the GST monthly data, we have found that it's not a great indicator of whether or not someone's eligible for the CEWS. Obviously there's some overlap, but we don't find that it's a great indicator.
If we were to go down that route and probe into all of the cases that make up that $15.5 billion—and that number itself is an extrapolation of a small sample—that would take more effort and, in my view, based on what we've seen so far, it wouldn't be worth the effort. As I said, we have found some cases, particularly in the promoter space, of people misrepresenting or committing fraud, and we're going after those people, but for the vast majority of people we're finding it's more within the realm of what you might expect, particularly with some of the prepayment controls we had and some of the education we did to help people fill out their forms.
Yes, everything has an opportunity cost, but I think at this stage it wouldn't be worth it based on what we have seen so far.
