Certainly.
The Canadian dollar has a very important role to play, given that it impacts both our exports and our imports because it determines the cost of imports. One way or another, there has to be a rate at which it optimizes the impact on the Canadian economy. Nobody really knows what that rate is. There are some estimates of what they call the purchasing power parity of the dollar, which used to be around 89¢ or 90¢. I don't really know exactly what it is right now. That doesn't necessarily mean that's an optimum rate for the exchange rate.
