Legal.
There's not too much push-back right now, as you said, but I'm just wondering about the future, with the ice melting. Part of our rationale in our defence for invoking our pollution laws to 200 miles is that Canada clause in UNCLOS. I think it's article 284, but it says in ice-covered waters we can enforce our environmental laws. I'm wondering what you think, as the ice is melting, about whether we're going to lose that defence and that authority to implement those laws.
The second example is the American and European claim of an international strait in the Northwest Passage. To make that claim, they have to prove there's frequent international, useful, commercial use, which, as you've said, is not practical right now. But as the ice melts it may be practical, so will they have a better claim, and will that impose a threat that we don't have right now on our sovereignty in that passage?
