It's funny. Every time I travel in the States, I always have to tell people that the person who was on duty on 9/11 and triggered the evacuation of North American airspace was a Canadian, and that Canadian fighters routinely will go across the border, as we permit U.S. fighters to cross. We use integrated border enforcement teams on the Great Lakes and in the waterways with the RCMP and the Coast Guard and everything else.
All of those things add back to that strategic goal of having the confidence of the Americans that we are doing our share in continental defence, which is one of the things that makes them treat the northern border maybe differently than the southern border. As I tell my American friends when I'm joking with some of them, and I hope I don't offend anybody, “There are not 13 million Canadians looking for a legal path to citizenship in the United States, and we're not your problem.”
However, with respect to NORAD and to Mr. Harris's point—and I think Ferry and I both have mentioned this—we are a continental resident, and this continent, aside from just parochial Canadian interests, has continent-wide concerns. To Ms. Gallant's point, our computer networks are entirely tied and do not recognize a border. Our hydroelectric facilities and the power grid do not recognize a border. Those things pass transparently across borders, so we both have an interest in that security. We would argue to expand NORAD into even the maritime domain and other domains.
