I'll perhaps start with that, Madam Chair.
My background, as I think I've mentioned before at the committee, is as a provincial deputy minister. This process is a little bit different from the provincial process as well, but essentially departments build most of their A-base, the known expenditures that they will have year to year, into the regular budget process, and that's what gets tabled early in the year. But then as we go through, for example, in a budget, we would often be involved with the budget discussions. For example, one of the items in our supplementary estimates this year is to recognize increased demands for programs under the Indian residential school support program. That would have become apparent to us, that the base we had in the budget we didn't feel was going to be sufficient to meet the demands we were seeing, and that's a requirement, that we'd be able to provide those supports for everyone who comes forward. So with that, we would have gone with the revision, essentially, to say that we are seeing greater numbers, and if that then is approved in the budget, then we hear often in a budget announcement a number of those programs, and indeed most of the ones that I mentioned in my opening remarks were things you would have heard as part of the budget. Then the process for regularizing and finalizing the details and getting them before Parliament occurs later in the year through the Treasury Board process in here.
Essentially it's a staged process, partly because of a difference between what things are fundamentally in an A-base that we can deal with at one point in time versus other things that arise later either because they're new or because we have revised estimates, for example.
