The major issue here again is tax leakage. There seems to be a significant discrepancy between Mr. Bruce's testimony and Mr. Normand's testimony.
You seem to be using exactly the same model as the one the department is using. You seem to be working on exactly the same information that the department is using. Something has to give here. You're working on the basis of information that is in the public realm, but it seems you can't reconcile the two ways in which these numbers seem to have been arrived at.
I can understand the political imperative to up the numbers to show tax leakage. I can understand how the provincial folks basically have to go along with the federal folks. But there is a significant discrepancy between your numbers and the department's numbers.
On all four items that you've itemized as the differences, where do you see the numbers? What is the discrepancy as you see it?
