Sure. All I can mention is that the costs associated with the change to the program are very dependent on the specificity with which we're provided in terms of the change. So it's not to say the costs provided in 2004 were incorrect; they were the baseline preliminary estimates we could do in two days, based on the question we had from the committee. There's a lot more detail in the proposed changes in the context of Bill C-265. We've tried to cost it based on the way it's described in the bill.
If we go back to 2004, the question was quite a general one posed by the committee, and we did the best we could, I think, as Mr. Brown mentioned at the time, in the time we had. The cost estimate at that time, again, was a minimum cost and a preliminary estimate, and I believe it was indicated that with additional detail and more time we could improve on those estimates.
For the purposes of Bill C-265, we've taken the much more specific information provided in the proposed bill and we've costed those individual elements, and that's how we've arrived at a more accurate estimate.
