It is a question that I can't duck as an admiral. It's a really good question.
The NORAD agreement was amended a few years ago to incorporate maritime warning in its mandate, looking at the maritime approaches in North America. It's a very important mission set.
I would assure you that NORAD pays a significant amount of attention to the maritime approaches to North America, as we do in the Canadian Armed Forces. We're very concerned about what is happening in our waters, on all three of our coasts. We work with the Americans to create a common picture of what is going on in our continental approaches. We use naval assets, as you would imagine, but we also make extensive use of space-based surveillance systems, including Canada's RADARSAT constellation mission.
It is a very important aspect of NORAD, and obviously for Canada and the Canadian Forces, we want to make sure we understand who's in our waters and what they're doing.
