Thank you for that question.
There's a colleague of ours, Frédéric Lasserre, who has done some very interesting work looking at the extent to which industry is actually interested in using the Northwest Passage. In fact, if he appeared here, he would probably be an excellent witness for this standing committee.
Basically, the point he underscored in his work is that shipowners are not rushing to build world-class vessels yet. There may be a number of factors there, at least for the Canadian Arctic. The Russian Arctic is a totally different story. Of course, there is the potential for paradigm shifts. What Professor Dawson was referring to is, potentially, one of those: What if you have a major disruption to the established maritime routes? Will there be more pressure on the northern routes? In theory, it is possible, but what we have to bear in mind too is that shipping in the north is seasonal, whereas shipping through the Panama Canal relies on accessibility all year round.
Then there's the issue of lack of predictability on how open the season is going to be—the navigation season in the Arctic, the shoulder season and so on. This could be a real disincentive to move shipping through northern waters.
Then, of course, there is also the question of infrastructure—
