Maybe I'll start, Mr. Chair.
It was unfortunately the Auditor General who shone the spotlight on the discrepancy letters, the 153,000. It wasn't, in fairness, until the OAG report arrived that we started looking at those in detail. The letter process was new. I think there was a sense within the IRCC that the number would come down naturally as people got used to the process and there would be fewer mistakes, and that after several years, it would be a good time to kind of pounce and start looking in detail.
What I would describe is a process of weeding down that list, but we're not done. There is work ahead of us in terms of confirming whether the people without status have effectively left the country or not. I don't want to leave this committee with the impression that the work is done. We have narrowed down the list to people who don't have valid status in Canada, but we have yet to fully confirm whether they have actually left the country or not. Finally, on the hard work—the people who ought to have left the country and who haven't—that's going to be tough work, and that work is ahead of us.
