This is one of the final stops of the train, the parliamentary approval of spending plans or an appropriation act.
Before it gets here, there needs to be a case made in the budget: someone has to convince the Minister of Finance and other cabinet ministers that a program is worth pursuing. That's step one.
Step two is the work of the Treasury Board itself. Before money can be spent, there are some detailed questions asked about how much is needed, what the objectives of the program are, how the department will achieve them, whether you could reallocate from within the department to fund the request. That's the Treasury Board piece.
It then comes here.
Then there's ongoing oversight of actual spending. I would point to deputy ministers as the accounting officer for each department. They are supported by such things as departmental audit committees, an internal audit function, and an evaluation function, which I have already mentioned.
Lastly, when the government's financial statements are prepared, there is an independent audit done to make sure that the departments are accurately reflecting their results in the way they were accounted for.
That's a kind of complete picture in 30 seconds.
