No, I absolutely do not. There are some costs perhaps that need to be kept private, but I believe that for a parliament to weigh, say, the value of a crime bill versus aid for immigrant children so they can assimilate better in terms of our official languages of Canada, or to understand that, you have to ask how much it is going to cost to do the one and how much it is going to cost to do the other. That balance has to be taken into account to make an informed decision.
So I firmly do not believe that the cost estimates should be kept confidential. In fact, what I've suggested here is the opposite. The House of Commons should require the government to present a cost estimate for implementation of a bill when it's introduced, or at least before second reading, and that the Parliamentary Budget Officer be asked to make an assessment of the methodology and the accuracy of the other figures in those cost estimates.
