I can go by the Arctic marine shipping assessment, which was done through the Arctic Council. I think it has already been referred to here in this committee by other speakers. It was done two or three years ago. It was a comprehensive study of shipping in the Arctic, both in terms of some legal stuff—fortunately not too much, so it's moderately readable—and also about expectations. The projections they made were not so much in terms of dates as routes. They said that the northern sea route, the northeast passage, if you will, over Russia will probably be open first. We have seen, and I'm sure you have read about, commercial traffic through the northern sea route of Russia. It is still at the point where every particular passage is noted, so it's not yet on a regular basis.
The Northwest Passage is seen as probably being the third to open for commercial shipping. As I understand from the Arctic marine shipping assessment, it is not perceived as a high priority for international navigation.
I want to distinguish what I'm talking about here. We're talking about international vessels passing through the area, as opposed to “local traffic” increasing. It's not meant to be a determinant, but it's about where the traffic is coming from, and that it is stopping in Canada to do something and then going away. I understand, from what I have read, that this will increase. We have, of course, seen the proposals for different mines and things like that taking place in the north.
