I'll start, and if Chief Superintendent Oliver wants to comment, he can follow up.
The Canadian passport, as you've described it, is an extremely valuable document for anyone travelling. As a result, it is subject to use and abuse in a limited number of circumstances by a small group of people who would seek to use it to facilitate terrorist movement and terrorist activity. We certainly see intelligence reporting that suggests that individuals actively seek the Canadian passport for those purposes.
Individuals may come to Canada and attain dual citizenship to gain the Canadian passport so that they can subsequently travel under that passport. We also see the active use of the passport with individuals who travel overseas. It makes it extremely difficult to track, because the vast majority of people, of course, travelling on a Canadian passport are travelling for good and legitimate reasons. So it's not immediately subject to question.
We see certain terrorist organizations in particular target the use of the Canadian passport because of its value, because it facilitates travel so easily and so smoothly. They will seek out dual nationals for the purpose of using that passport to facilitate travel. We've seen at least some indications of that in regard to Hezbollah, for instance.
So that document is an extremely valuable document, and gaining citizenship in order to be able to use that document is a noted goal.
