The Budget Isn't What You Think It Is. How Federal Money Actually Gets Approved — Estimates, Supply, and the Votes That Can Topple Governments.

Canada's federal spending process runs on two parallel tracks that are routinely confused. The budget is a policy statement: the Minister of Finance's plan for taxing, borrowing, and spending, moved as a ways-and-means motion and implemented through budget implementation acts that change tax law and program statutes. Spending authority, however, flows through the estimates-and-supply track: the Main Estimates (the government's itemized departmental spending requests, tabled by the President of the Treasury Board by March 1), reviewed by House committees, and granted through appropriation acts passed in three fixed supply periods ending June 23, December 10, and March 26. Supplementary Estimates (A, B, and C) top up the mains during the year, and interim supply tides departments over before the mains pass. Each supply period also contains the opposition's allotted days — the limited slots on which non-confidence motions ride. Every supply vote is a confidence matter: a government that cannot pass supply cannot govern, which is precisely how Joe Clark's government fell in December 1979. The Parliamentary Budget Officer provides independent costing and analysis throughout — frequently contradicting government projections, as our PBO explainer documents.
