I think it's safe to say, based on what the Auditor General found, that this was not being followed and there were definite gaps in the department.
I'll go back to the Auditor General.
You found that IRCC did not identify which students were expected to leave. This has to do with removal tracking after permits had expired. The report says, “We identified”, which means your office. You talked about 39,500 individuals who shouldn't have been in Canada because they'd lost their status.
Was IRCC not aware of that number?
