Could I just jump in?
I would go a bit beyond what Professor Coates is saying, in that sovereignty isn't just about who owns the land and where it is. As the second section of the sovereignty declaration in front of you says, there's an evolving nature of sovereignty in the Arctic. I think Canada would do well to look at that. There are different interpretations of what sovereignty means in the Arctic, and I don't think that just because it's not cut and dried in the way Professor Coates said doesn't mean that we don't move forward on it. I'm sure Professor Coates didn't mean that's the only way sovereignty is defined, but we're looking at it more broadly.
