Canada's fiscal calendar now has its date. The Carney government will present the federal budget on November 4, a fall fiscal plan that Finance Minister Francois-Philippe Champagne says will feature generational investments.

The budget is expected to concentrate on housing, infrastructure and defence, the files the government has tied to its argument that Canada must build faster and rely less on a single trading partner.

Opposition reaction was immediate. Conservative Leader Pierre Poilievre dismissed the plan's framing as 'generational debt,' setting up the central argument of the fall sitting: big-ticket building programs against the size of the deficit they require.

The November 4 date also matters procedurally. A budget is a confidence matter, so the vote will test the minority Parliament's arithmetic and each opposition party's appetite for an election.

Between now and budget day, expect a stream of pre-announcements designed to build the government's case — and opposition efforts to define the document before Champagne rises in the House.
