It's a great question. At the end of the day, is surveillance about sovereignty? I would pose the question to this committee. It would have been a great question to ask the last group. I know the answer for when I was there.
Does the United States of America advise the Government of Canada whenever its nuclear submarines pass through our Arctic? The short answer is no. Would it be great to know that they're there? They usually provide us with a block of 100 square kilometres. It could be found somewhere in there. My colleague might know. He was south of the border at the time. Beyond that, there's not a lot of detail.
Is that about sovereignty? Is it about surveillance? Yes, they tell you that they're up there in this area, but I think we need more. In 2010, we did a pilot. We put some underwater cables through a very small part of the Northwest Passage, from a surveillance perspective, and it worked.
Part of the challenge in the north is that a whale gives off almost the same echo that a submarine does. I've been there. I got a call in the middle of the night once, saying they'd found a submarine. I think it turned out to be a whale at the end of the day.
All that is to say that it comes back, seriously, to the question of whether it is just about surveillance, or is it also about sovereignty? It's not about just knowing; it's about how this is Canada. This is ours.
Internationally, the United States of America still argues that from an international point of view.
