The direct answer is no. I don't think we have a cost, but I think I can offer some observations to help inform the discussion.
First of all, in relation to the technical bill itself, technical bills generally are generally made up of comfort letters that are relieving changes by definition. Taxpayers identify an issue in the legislation that restricts their ability to do a transaction in one way versus another. There is a commercial reason for doing it in the way they wish, which the tax law impedes; in looking at that, we determine that there's not a difference between the two and recommend a relieving change in that area. There's not a revenue cost associated with that, or an abuse associated with it.
Having said that, we have used--and Bill C-10 is an example of this--technical amendment packages to include press releases that have been put out to try to deal with certain concerns or revenue issues. Bill C-10 itself includes provisions dealing with charitable contributions, donation schemes that were encountered a few years ago. There are also provisions dealing with restrictive covenants, an issue discussed in the Auditor General's report. While we believe that the announcement of those changes has been effective in constraining those transactions, it's obviously important that the legislation ultimately be enacted in order to give effect to those changes.
I can't point to a revenue cost associated with non-enactment; nonetheless, your essential point remains valid. Enactment, of course, is required, and it would be desirable for it to be done as efficiently as possible.
