Perhaps I can address that. It's interesting because the timeframe that's necessary in order to produce the main estimates documents, of which you have an example, plus the reports on plans and priorities that are done by virtually 90 departments and agencies, takes several months. So in fact the closing date for getting new approvals that are required by, say, the Treasury Board to include items in main estimates...it's actually finished almost in October for the following year. So it's very difficult in the approval process to ensure that all those things are lined up and then have a document that's produced and accurately reflects all of the kinds of information that you would require. So there's a huge lag between when in fact the departments prepare the material and when it's presented to Parliament, which causes the first problem.
Again, to allow parliamentarians to see the changes during the year, yes, now we have three supplementary estimates; in days gone by we've had up to seven or eight. So it's very difficult, and it's the lengthy times it takes to prepare the information, to get the approvals necessary to include it before Parliament, as well, of course, as the review by Parliament itself. It just takes a long time.
