It's interesting the way you asked your question. If you review the literature, some of which you received from Dr. Lajeunesse and others about the sovereignty issue....
Frankly, I don't see that Canadian sovereignty is under attack or under threat. We have sovereignty in Canada. It's ours, and I think you've heard from Global Affairs Canada, which spoke from a legal perspective about what sovereignty is. From a defence perspective, I guess our interest in sovereignty is speaking to what you offered, Commissioner, in terms of the security piece—sovereignty ignored is perhaps sovereignty lost.
From a defence perspective, our key interest in the north is maintaining an awareness of what's going on up there and having a presence year-round both to be able to see what's happening and to respond to what's going on, be that incursions from the kayakers, who were mentioned there, or other ships that weren't forecasted, or those who might seek to do us harm at some point when the waterways open up to the point where maritime traffic is significantly increased perhaps over the next decade or two. Those are the kinds of things we pay attention to.
