We're definitely satisfied with the information we're getting from CRA. I think there's been a tremendous improvement over the last several years. One should not stop making improvements; however, both the methodological changes that have been put in place and the frequency and quality of the data we get from the agency have improved tremendously.
In terms of the projections of the department, I think what one needs to bear in mind is the underlying volatility out there in the economy. Going to your point on the revision in the deficit for the year that's under way, half—not quite half, almost half—of that revision was due to greater expenses related to the auto sector, and the other half, roughly, was due to the further deterioration in the economy vis-à-vis what we expected at the time of the 2009 budget.
I'd give you just one number by way of example. In 2007-08 corporate income tax revenues were $40.6 billion, and we're projecting them to be $23.8 billion in 2009-10. That's tremendous volatility, and it's something we have to deal with. Yes, we'll forecast as best we can, as do others, but the amount of uncertainty that's out there is still tremendously high. It's not going away. We provide the best projections we can, but I don't think one should underestimate just how difficult it is to come down on a point estimate when one has roughly $500 billion in combined expenses and revenues. For me, that's the biggest issue.
