On our part, with the coast guard, we have a strong and increasing relationship with National Defence around these issues. First of all, we, along with others, are part of the marine security operation centres that are run by DND. As you're probably well aware, there's one on the east coast and one on the west coast. There are coast guard people embedded in that. All of our information regarding marine domain awareness and so forth gets fed into those processes.
In the last three years we've also begun to have ongoing joint exercises in the Arctic, working with DND. What we've been doing in those exercises is testing our ability to work together, the ability of our respective systems to communicate with each other, and we practised joint exercises in a number of situations.
I'll give you one example, simply for context, of the benefit of those. Coming out of last summer's exercise, for the first time we were able to develop the protocols and procedures that would allow coast guard helicopters to land on DND vessels and vice versa. We are working on that interoperability, to be better placed, obviously, to support the Canadian Forces in the north and wherever else they may need help from us.
