Maybe I will start and see if colleagues want to offer anything from a departmental perspective.
It does go to the heart of the role of the Treasury Board, and I'm not speaking of the Treasury Board Secretariat, but Treasury Board, the cabinet committee. Our system for expenditure control is very much based on the challenge function and additional details that departments need to submit before they get spending authority.
You're quite right, from a projection perspective, could departments actually project in a document what they would like to spend during the year, what they think they will spend? Yes, they could. By putting that number into an estimates document that goes to Parliament and is the basis for an appropriation act—remember, this is the key for parliamentary control over spending—I think you'd be circumventing the role of the Treasury Board, which is where you get a key challenge function. And these estimates do support the appropriation acts, which is Parliament's fundamental control over spending. So if you were to actually include additional dollars in those documents, without having been through the challenge function of the Treasury Board and the approval of the Treasury Board, I think you'd be potentially risking one of our key controls, which is that departments can't spend money until they've been through Treasury Board, which then eventually goes to Parliament.
