When supplementary estimates are presented, there is a list of vote transfers, increases to votes. You'll see that it could be new money that's being voted or it could be money that's coming to a department from another department. You will see that in the supplementary estimates: the vote for one department is increasing, and you'll see a corresponding decrease from another department. I did mention the example of the Canadian Food Inspection Agency and Agriculture Canada. It's quite common, but you will see that through supplementary estimates. It's the mechanism.
