There's a lot in that question.
CBSA, of course, reports to the Minister of Public Safety, with whom I work, obviously, very closely. The fact is that we revoke these credentials regularly. We have a constant system of ongoing revocation of credentials. We take this very seriously.
As you know, the system that we implement requires us to assess the risk to aviation safety. I've asked my officials to examine whether that is an appropriate test, but I would point out that, substantially, many of the people who were the objects of interest in the recent television report all had their credentials revoked.
