Canada is part of the DPSA, the Defence Production Sharing Agreement. We are considered a domestic source in the U.S. As you know, my company and many others in Canada and Quebec--Northrop Grumman and Lockheed Martin--do quite a bit of work for the U.S. Department of Defense. There are very close ties between the Canadian defence industry and the U.S. defence industry because of the treaties that were put in place by Canada and the U.S.
