Sir, I'm going to have to beg off that question and delegate up, if it's possible. I will clarify that we have that infrastructure in the north. I will make use of it when I'm able to. For my operations, I can make use of NORAD's infrastructure, but I do not own or control it. We now have all of our infrastructure in the north under our assistant deputy minister for infrastructure and the environment, so we have a centralized control of infrastructure.
The primary user is NORAD for that, and for our forward operating locations and installations that go along with that. There are four of those. I make use of those because they're there. Infrastructure is limited, and they can be launching points for other operations.
In terms of the north warning system itself and the future, I'm not on the inside track of any of that analysis or discussion, so I don't think I can really add any value there.
