Mr. Chair, again, thank you for the question.
I would respectfully disagree with the premise that there was a failure in this case. As referenced earlier by our minister, there are several lines of defence—security screening programs are one—and they do begin before people arrive in Canada, as they come to our border and also once they have arrived in Canada.
I would say that the third line of defence, which is national security investigations, in this case was very successful.
I can again assure the committee that as soon as CSIS had that information, we acted, we assessed, and we mitigated the threat in conjunction with our security partners.
