As far as we can see now, it's not creating a clear new threat for Canadian sovereignty in the north. My concern about this is when Canada will actually make its claim regarding the continental shelf, which is when there will be risk of conflict between the Russian and Canadian views.
What could happen now in eastern Ukraine and Europe could have an effect on this, just by putting a bitter tone to the discussions regarding the North Pole, for example, because the two countries both want to have the North Pole. It's funny but it seems to be going in that direction. So the impact it could have is that Russia and Canada could have a bitter tone to their relationship and be less likely to compromise on this issue. So it could have an impact on this, yes, but not directly on Canadian sovereignty—not now.
