The Government of Canada position, up to this point, has been to really lecture the Americans about the virtues of global free trade and to assume that Canada's interests are best served by getting rid of buy America policies.
I guess the way I'd frame it is that Canadian producers certainly do need access to the American market, but the best case scenario for Canada is not actually a removal of buy America provisions but rather a specific Canadian exemption from those provisions, because then our producers could sell into the U.S. market with less competition from offshore producers.
I don't think this is a totally unrealistic goal. When the United States put tariffs on steel imports in 2002, it actually did exempt Canada from those tariffs. That's the position my union has put before Congress in the United States: we support buy America, but we'd like to see Canada exempted.
And certainly, you're right that a buy Canada policy would provide a very valuable negotiating tool, in the sense that we could say to the Americans we'll exempt you from a buy Canada policy as long as you exempt us from a buy America policy. I think that's the way to go.
