Madam Chair, I'll just respond to that.
I think, as I said in my earlier response, there's cost, and one could do a cost-benefit analysis, but there's also the element of time, so we have to....
If we go back to that moment in time, we were building a brand new system. This wasn't running off of our existing CRA system; we built a new system. In terms of the time that would have been required to make sure that the employers could provide the SIN and build into our IT system the ability to use that information effectively, we're certainly talking about way more than a couple of days. We would have been having to delay for a period of time. Now, can I put a cost on that? I'd have to think a little bit more about how one would cost that.
On the other side, we knew we'd have an opportunity to get that information and come back at the back end.
