Yes, absolutely, we support it.
You're correct, of course, that it's already an offence to take training for the purpose of supporting the activities of a terrorist group, and Mr. Khawaja was convicted for that very offence.
I'd refer you to the Government of Canada's counter-terrorism strategy, called Building Resilience Against Terrorism. It has four pillars: prevent, detect, deny, and respond. In the case of Mr. Khawaja, we were mainly in the world of responding. I think the government is trying to move its resources in the security intelligence community more into the world of “prevent, detect, and deny”, because those are worlds that it's much better to be in. Anything we can do that would forestall or nip in the bud or cut off a potential terrorist activity before it happens, even before an individual leaves Canada, we consider to be a strengthening of the tools we have at our disposal.
