The Canadian navy, operating as part of the Canadian Forces, establishes a presence in the Arctic, so there's a physical manifestation of that. The Canadian navy and the Canadian Forces have the ability to work with the whole of government to deliver a range of capability that is not necessarily naval capability, but it is bringing together the Canadian Coast Guard, Environment Canada, NRCan, INAC, and a bunch of other partners in the north to make the best use of the capability that exists in Canada and to be able to focus it. Rather than the Canadian navy, it's far more my organization in Canada Command that helps the whole of government deliver that, where Canadian Forces capabilities are involved.
I would say that the Canadian armed forces and the Canadian navy, as part of that, have a very good ability to manage relations with our Arctic neighbours in order to understand what they're doing, what they're working on, and to work together on creating capacity in the Canadian north and in the Arctic, as a region, so that we can exchange information, we can exchange awareness, and we can be prepared to deal with current and future threats as they emerge. I think all of that promotes Canadian sovereignty and responsibility in the Arctic domain.
I'm not sure I've given you an exhaustive answer, but off the top of my head, that's what I would say.
