If they are refugee claimants, for example, when they have begun the process we would have written up a report on them. That report would remain dormant while they go through the process. They would go through the IRB a number of months later—or many months or years later, but that's going to be resolved—they would make their case, and then the IRB would decide if they are refugees or not.
If they are refugees, then of course they would be given information about how to apply for permanent residence and that would work its way through.
If they were refused refugee status, at that point the removal order becomes executable, so at that point directly CBSA would be notified, not necessarily by CIC but with the records through IRB, and then it would go into a backlog to start processing towards removal.
While they're doing that, the client might apply for status within Canada. If we became aware of it, we would likely advise CBSA that this person is not entitled to stay in Canada.
If they made a refugee claim or something like that and at that moment we became aware that they have a criminal record in the United States or somewhere, we would likely call either the police or CBSA at that point for them to come and interview the person early in the process.
