I think everybody understood, in the end, that this was the way to go. Naturally it presented a change for some people, certainly when we put an expiry date on the 900 SINs, which are the social insurance numbers that are used for temporary workers in Canada. So each year they have to re-get them, if you like, whereas before they were kept open, which was not considered the way to go at it with integrity. So we changed that, and that helped us reduce our gap, if you like, which the Auditor General just spoke about.
I don't think there has been a big outpouring against this. I think people understand that it's what you need to have to truly prove who you are. The documents we use have come out of a conversation we had with other departments in the federal government and provinces to ensure that we are using, truly, the most robust documents to establish something as important as a social insurance number.
I think we have found that there are tiny populations that perhaps are a bit inconvenienced by this because of where they might have been born. For instance, we've had to make sure there's an extra step, if you like, for Canadian children who were born abroad. So there's an extra step in doing that. We find these things out along the way. But basically the system is working well.
