I would decline to comment on the level of the dollar, just as I wouldn't want to make a clear statement about where oil prices might be over a certain horizon. If oil prices were to rise, chances are that the Canadian dollar would rise. If nothing else, we're moving at the same time. If oil prices went down, it would be the same thing.
There is no magic number for us to have on that. It's driven by almost every fundamental in the economy. We tend to think only about those two headline ones, but underneath all that is the economy's competitiveness and the forces acting on it. The exchange rate is a major equilibration channel that is affected by almost everything in the economy and outside of it.
