Thanks very much, Mr. Chair.
We can only spend money that Parliament provides to us. As you know, we get money in dribs and drabs through the year. We have the main estimates, and then we have supplementary estimates. So just about every single organization will carry forward an amount. It's a timing difference. Managing to one percent, as our deputy said, is basically what we have to do, or we would not be complying with authorities. We do get some money that comes in at the end of the year.
In terms of your question about what we've done with the $13 million, well, of course we've allocated that to other priorities, including the Canadian Wildlife Service. We have supplementary estimates before the House. If they are approved, then we'll be able to use that money. Otherwise, we are in a position of only being able to budget and spend the amount of money that Parliament authorizes for us. Indeed, we've done that.
If I could, I'll just provide a bit of a skeleton in terms of our main estimates and our supplementary estimates. Included in our main estimates is also about $74.5 million that's dedicated for new work. So we have to spend it on clean air initiatives, on toxics, and on the clean air agenda. It's also decreased by a certain amount of temporary funding we had for species at risk, but our supplementary estimates are fixing that. There's a bit of a timing difference. Also, as our minister said, there's an expenditure reduction of somewhere in the order of $10 million.
So that brings us to a net increase of about $38 million. Now our supplementary estimates, as we said, are close to about $290 million, but there's a big item in there for Harbourfront Centre, which we can't use.
So it's a bit more than last year, but we are doing everything we can to reallocate. One other area that we did focus on department-wide was one of our larger expenditures, which is travel and correspondence, and not just in one program. We believed we could create efficiencies, and we've done that as well.
