In terms of the review, we're both reviewing these specific individuals and backchecking what occurred and whether procedures were followed, and if procedures were followed, what changes to procedures may be required. We're also taking a representative sample of closed files that were similarly screened positive to see, in light of the information available today, whether changes to the procedures are needed.
As the minister said, there are three lines of defence. The CBSA's first involvement is actually in the security screening process before people are issued a visa or status in Canada. In 2023, concern of various levels was expressed about 7,000 people based on that process. Liaison officers are situated around the world, and roughly 7,500 people were “no boarded” before they even got on a plane to Canada. In 2023, there were 35,000 people who were allowed to leave but who did not enter the country, and roughly 3,500 people, because of serious inadmissibility concerns, not just national security but organized crime and others, were stopped.
What I'm trying to say is that we do have checks and balances that work thousands of times a year, but we're asking ourselves the same tough questions about whether procedures were followed and whether, if they were and this individual was not caught, different procedures could catch them in the future.
