Very briefly, we have really good mechanisms in place, and one is in NORAD.
We also can't look at Arctic sovereignty strictly as national defence. With Minister Tootoo, we have to look at the wider picture of what type of presence we want to have in the Arctic with our Coast Guard. As National Defence, we provide one umbrella for that. We have good mechanisms in place, but we do need to be mindful of what that defence is going to look like, what type of surveillance, what type of presence.
I don't want to get ahead of myself before the defence review in answering some of these questions.
