The committee's work this session has been dominated by two overlapping tracks: clause-by-clause scrutiny of the spring budget implementation bill, Bill C-30, and the pre-budget consultations for the 2026 budget, with a second budget implementation bill, Bill C-31, and the fuel affordability bill, Bill C-38, appearing at the most recent meeting. Across the Bill C-30 meetings, departmental officials from Finance, the Canadian Food Inspection Agency, Health Canada, Employment and Social Development and the Bank of Canada appeared repeatedly to explain measures on CPP contribution rates, the labour mobility deduction, pesticide and food security mandates, Bank Act national security review, disability tax credit certification and the fuel excise tax suspension. A recurring procedural pattern emerged: Conservative members proposed numerous amendments and subamendments seeking added reporting requirements on transparency and accountability grounds, while government members opposed them as duplicative of existing actuarial and tax expenditure reports, or as requiring data not yet available. Debate was lengthy, with the committee spending over 22 hours on one amendment alone, and several meetings ended without votes being reached.

The pre-budget consultations drew an unusually broad cross-section of civil society. Indigenous organizations were prominent, with the Assembly of First Nations, Inuit Tapiriit Kanatami, the Métis National Council and the Ontario Federation of Indigenous Friendship Centres all presenting distinctions-based asks, from a $360-billion infrastructure gap and drinking water advisories to an Inuit Nunangat fund, a university and tuberculosis elimination. Housing and homelessness groups—the Co-operative Housing Federation, Habitat for Humanity, Indwell, Options for Homes, the Women's National Housing and Homelessness Network and the Intentional Community Consortium—converged on calls for clearer targets, dedicated capital streams for supportive and deeply affordable housing, and continued CMHC and rental assistance funding beyond expiring programs. Business and industry voices, including the Canadian Federation of Independent Business, Canadian Manufacturers and Exporters, the Conseil du patronat du Québec, the Fédération des chambres de commerce du Québec, the Canadian Bankers Association, the Canadian Vehicle Manufacturers' Association and the Aerospace Industries Association, generally pressed for tax competitiveness, regulatory simplification, procurement reform and measures to counter tariff-driven job losses. Labour, anti-poverty, health, food security, media, arts, municipal, clean technology and financial technology organizations rounded out the witness lists.

Witnesses agreed on some points and diverged sharply on others. There was broad support for the disability tax credit reforms—lifelong certification and expanded certifier eligibility—though organizations like March of Dimes, Community Living Toronto and the Canadian Council on Rehabilitation and Work argued the reforms should go further, toward a portable disability status outside the tax system. Skilled trades measures in the spring update were widely welcomed by operating engineers, labourers and mechanical contractors. On the fuel excise tax suspension, however, witnesses split: the Canadian Taxpayers Federation urged making the cut permanent, while economists Genest-Grégoire and Godbout called the holiday poorly targeted and regressive in benefit, and Au questioned only whether its duration matched the roughly 34-week energy market recovery he sketched. Similar disagreement ran through fiscal policy, where the Montreal Economic Institute and C.D. Howe warned of deficits reaching $117 billion by 2035 and urged spending restraint, while unions and anti-poverty groups called for progressive taxation, windfall levies on oil and gas, and expanded social investment. On the sovereign wealth fund, Robson and Brossard criticized it as debt-financed and unlike Norway's model, while departmental officials provided only partial costing.

Several themes recurred across otherwise disparate testimony: the need for longer, more predictable funding terms and simpler application processes; the argument that social spending—child care, mental health, housing, food security—is economic infrastructure with measurable returns; and concern about U.S. tariffs and trade uncertainty shaping manufacturing, agriculture and automotive recommendations. Over time, the committee's focus shifted from pre-budget consultation hearings in May and June, where witnesses laid out spending and tax asks, toward intensive clause-by-clause work on Bill C-30 through June, marked by procedural friction and a sustained Conservative amendment campaign. By the October meeting on Bills C-31 and C-38, the committee had moved to a new legislative package, with the minister appearing on both bills, the fuel tax suspension's cost pegged at $5.3 billion and its phase-back schedule set out, and amendments carried on division to extend the full suspension to July 1, 2027 and set a 50% rate through September 1, 2027—an outcome that ran against the advice of the economists who testified against the holiday.
