I think we have an opportunity to establish what those shipping lanes will be. Completing the mapping of the Northwest Passage is probably at the top of the list of what's required in order to make decisions about how to manage that. I see it as being firmly within Canada's rights and jurisdiction to complete the mapping. It's going very slowly right now. We need to look at some different technologies that will allow us to do that more effectively.
Then, in terms of your question about how to enforce and regulate, I think there are mechanisms for doing that, but what we should be looking at is establishing the shipping lanes and not just letting free passage through any of the channels in the archipelago.
