Not having seen the detailed cases themselves, I would have to assume.... Let's back up.
The 800 were investigations that were a result of a quality assurance exercise. As the deputy explained, we take a snapshot of a number of cases and do a review. That found that 800—most of them were student direct stream applicants—had some kind of fraudulent document as part of their application.
On the question of how they would become permanent residents, the officer who would have reviewed the permanent resident application would have had a conversation, a back-and-forth—what's called a procedural fairness letter—with the client to ask for the situation of the document and would have made a finding that either their response was acceptable or they got a new document. I wouldn't be able to postulate on each case, on the basis of its merit.
I don't know that it's a reward, but there are checks and balances, especially when we move into a PR stream, to check on the validity of those documents.
