Yes, I definitely have. I'm glad you asked.
I guess the first thing I would say is that while you say “tied to”, I think we either go into a common North American currency or we don't do it. We don't do the peg thing, and that's a long story.
Should we have a common North American currency? It would certainly have some definite economic benefits. Frankly, I don't think the appetite is there for it in Canada, and it's not there for it in the U.S. But if the political climate changed, I think it could be something that from an economic point of view we should take pretty seriously.
A lot of the arguments against a common North American currency don't hold up very well. Obviously, the Bank of Canada cannot even whisper, hardly, that they would consider it. If I were the government, I wouldn't want to get into those discussions, and if I were a senior finance department official, I wouldn't either, because there's a real danger in saying that we want to. Among other things, you rather lose your negotiating power with the Americans.
But that's not to say that a common North American currency.... It's something that's out there as a possibility, yes. I think it has more attractive benefits.
