NORAD, when it comes to the Arctic, is going to be more concerned with the classic foreign defence aspects of this, because the military of course doesn't have the mandate to be fining ships for vessel pollution and things like that. That's done by Transport Canada and other agencies.
That said, because we're talking about the Arctic and the austere conditions, one of the issues is that something like a search and rescue event that may or may not involve the military could easily turn into a bigger situation just because of those austere conditions. For the most part, though, the military operating in the Arctic has the function of aiding civilian powers. We are keen to call on the military because they have that unlimited liability, and there is always a possibility of dying when you go to the Arctic.
Really, in Canada especially, there's always been a whole-of-government approach. There are many other agencies, before the military, that have primary mandate for making sure that the Northwest Passage is navigable, that we have the aid, that we have them charted, etc.
What I'm saying is that the more we do of that, the less NORAD has to be tracking everything going on.
