In the U.S. case, everybody in the marketplace knows that the U.S. economy is at full employment and that they have begun to normalize interest rates. Everybody also knows that the Canadian economy is in a different spot and that we're likely to strike an independent course. Those two understandings are built into the marketplace and are in the prices that we see today.
Assuming that those two things unfold as people expect, I would not expect large movements in the Canadian dollar, but if something else changes, such as the price of oil, for example, then it would.... It's why we can't make some sort of firm prediction. It's really the market that drives it, and we appreciate that, because the market sees everything, and all those transactions, billions of transactions, are driving the dollar around. It would be wrong for us to try to offset those things.
Finally, is a low dollar always a good thing? Well, it is selectively good. It is good for a company that has mostly Canadian content in their business. That would be, say, in agriculture, but not necessarily, because equipment may be imported.
