I would assure Canadians that we have multiple lines of defence in place. If we don't capture them at the stage of security screening, we also look at people coming to the country. As you heard from earlier testimony, about 7,500 people were “no boarded” prior to even departing for Canada. About 37,000 people were turned away from Canada upon entry.
Then we have an additional line of defence in terms of our inland investigations. Last year we launched 8,000 inland investigations based on concerns about inadmissibility. When we find inadmissibility, we take those cases to the Immigration and Refugee Board, who's the decision-maker. Last year we removed 15,000 people, of whom about 700 to 800 were cases of serious inadmissibility.
There are multiple lines of defence in place. We don't rely on a single point of failure. We have multiple lines of defence. We're asking ourselves, do improvements need to be made? I think that's a powerful message for Canadians. We do want to know if improvements can be made. If there can be, we will make improvements.
