Federal Budget 2026: Critical Minerals Miner Stakeholder Brief

Executive Summary

1. Mine development costs become 100 per cent deductible, up from 30 per cent, yet the $15 million Canada Growth Incentive excludes mining businesses, so miners get the write-off and their investors do not get the new exemption.
2. The strategy renewal adds about $106 million a year (calculated) from 2027-28, and Budget 2025's $2 billion Critical Minerals Sovereign Fund is not mentioned anywhere in Budget 2026.
3. When a miner buys Canadian resource property from a non-resident, the purchaser's withholding falls from 50 per cent to 30 per cent of the price on January 1, 2027, the most direct deal-cost change in the budget.

The budget is positive for explorers and developers and thin for producers. Juniors get five years of flow-through certainty and developers get full write-offs. New program money is small, starts in 2027-28, and most federal project support is Crown financing announced before tabling.

Top 5 Relevant Budget Measures

1. Exploration tax credits. $956 million over five years, $1 million in 2026-27, for flow-through agreements entered into on or before March 31, 2032 (Tax Measures: Supplementary Information, Personal Income Tax Measures). The 15 per cent METC and 30 per cent CMETC were due to expire on March 31, 2027. Antimony joins a list that the Notice of Ways and Means Motion shows already includes copper, nickel, lithium, uranium, zinc and phosphate. The cost peaks at $307 million in 2027-28 and then holds at $216 million a year. Home page.

2. Critical Minerals Strategy renewal. The row costs $1,661 million gross and $1,348 million net over five years, with -$11 million in 2026-27 (Budget 2026: Masters of Our Destiny, Chapter 1, s. 1.3). The net figure deducts $200 million previously provisioned and $113 million in projected revenues. NRCan's share is $424.4 million over four years from 2027-28 for technology, geoscience and targeted project funding. The rest of the row is the exploration credits and $54 million for helium. Home page.

3. Productivity Mega Deduction. $36,055 million over five years, $2,015 million in 2026-27 (Budget 2026: Masters of Our Destiny, Chapter 1, s. 1.1). The Tax Measures supplement says it would raise the Canadian development expense rate from 30 to 100 per cent. Chart 1.2 projects a long-run 8 per cent gain in after-tax returns for oil, gas and mining from accelerated depreciation since Budget 2025. For a developer near a production decision, this moves the tax shield from a decade to year one. Home page.

4. Supporting Canadian workers and businesses. $11,324 million net over five years, $2,178 million in 2026-27 (Budget 2026: Masters of Our Destiny, Chapter 2, s. 2.3). All of it was announced between May 4 and October 21, 2026, so it is re-announced money. It includes targeted support for copper, mining and critical minerals and $6.1 billion for Ontario that covers the Ring of Fire. The chapter does not say how much of that $6.1 billion sits in this row. Home page.

5. Mackenzie Valley Highway. $3,100 million over five years, $38 million in 2026-27, rising to $1,030 million in 2030-31 (Budget 2026: Masters of Our Destiny, Chapter 2, s. 2.1). The budget fully funds construction of an all-season road of about 800 km. It is the only northern corridor with a cost line. Grays Bay Road and Port, built to move critical minerals to export, has none. Home page.

Not in this budget

Apply the critical minerals strategy to phosphates

Jean-Denis Garon, Bloc Québécois, CPAC, Nov 4

Phosphate was already on the exploration credit's list. The draft legislation restates it and extends the credit to 2032, and the strategy renewal names no minerals.

Bringing critical minerals from mine to market

Partly

Asks compiled by Stephen Taylor's AI Public Affairs Toolset, September 15 to November 5, 2026.

The sector can claim the credit renewal, its top tax ask, in full. Permanence and feasibility-study costs did not move. Bill C-31's CEE change was already before Parliament, so the feasibility fight continues there and in the next budget cycle.

Risks

The feasibility-study exclusion stands. Bill C-31 narrows the Canadian exploration expense to exclude economic viability and engineering feasibility costs, as Budget 2025 proposed. Budget 2026 adds nothing to restore them through the exploration credits or any other route.

The credits now carry a 2032 expiry. Agreements entered into after March 31, 2032 lose both credits unless a later budget renews them. The amended flow-through definitions also cap eligible exploration expense at amounts incurred before 2033 (Notice of Ways and Means Motion to amend the Income Tax Act).

Budget 2025's tools have disappeared from view. Budget 2025 gave NRCan $2 billion on a cash basis from 2026-27 for a Critical Minerals Sovereign Fund and $371.8 million for a First and Last Mile Fund (Budget 2025, Chapter 1). Budget 2026 does not name the Sovereign Fund and mentions the First and Last Mile Fund only in an overview table of actions since 2025. It names a $2 billion Canada Critical Minerals Accelerator delivered by EDC. If the Accelerator replaced the Sovereign Fund, the money moved from a department to a Crown lender with different risk rules.

Program timing is late. The minerals row is negative in 2026-27 and strategy money starts in 2027-28. The $113 million in projected revenues booked for 2029-30 and 2030-31 suggests repayable or fee-based elements, which the budget does not explain.

Crown financing is being reorganised. BDC and EDC are being merged into a single development bank under a specially constituted board (Budget 2026: Masters of Our Destiny, Chapter 6, s. 6.3). The budget says existing products will be fully maintained. Deal flow through the Accelerator could still slow during the transition.

Market assumptions are favourable but exposed. The private-sector forecast puts the dollar at 72.1 US cents in 2026 and real growth at 1.0 per cent (Budget 2026: Masters of Our Destiny, Annex 1, Table A1.2). In the global supply disruptions scenario, real growth in 2027 falls to 1.0 per cent from 1.7 per cent (Annex 1, Table A1.12).

Opportunities

The 30 per cent Critical Mineral Exploration Tax Credit covers antimony for flow-through agreements entered into after November 5, 2026. Both credits remain available to agreements entered into on or before March 31, 2032.

The Canada Critical Minerals Accelerator, launched in July 2026 with $2 billion, invests alongside industry in projects that supply minerals for batteries, semiconductors and defence equipment. Its first deal backs Teck's $850 million Trail expansion, alongside $400 million from the Canada Growth Fund (Budget 2026: Masters of Our Destiny, Chapter 1, s. 1.3). Crown financing is covered on the Crown corporations page.

The Canada Strong Fund, with an initial $25 billion over three years, will co-invest alongside federal lenders. The budget's own example is a Canada Infrastructure Bank concessional loan for road and power so a critical mineral mine can reach a final investment decision (Chapter 2, s. 2.1). Legislation to make the Fund a standalone Crown corporation is due in the coming months.

Approvals are being compressed. Bill C-39 targets federal decisions within one year of a comprehensive application, with a lead federal assessor and a Crown Consultation Hub (Chapter 2, Figure 2.2). The Major Projects Office lists Red Chris, Canada Nickel's Crawford Project, McIlvenna Bay, Matawinie, Sisson and the Labrador Trough corridor among its referrals. A new major projects management entity gets $187.4 million over five years.

Indigenous equity partners have new financing routes. The Indigenous Loan Guarantee Program is being consolidated in the Canada Infrastructure Bank, and Annex 3 lets the First Nations Finance Authority lend to Indigenous-owned special purpose vehicles. The Partnerships for Indigenous Workforce Readiness Fund gets $451.8 million over four years from 2027-28.

Deal costs fall for cross-border transactions. From January 1, 2027, purchasers withhold 30 per cent on specified taxable Canadian property such as resource property, down from 50 per cent, and 15 per cent on other capital property, down from 25 per cent (Tax Measures: Supplementary Information, International Tax Measures). Qualifying section 85 rollovers are exempt if filed within 30 days.

Allied capital is opening up. Canada signed a treaty framework letting the European Investment Bank invest in Canadian critical minerals projects and is starting work on a raw materials stockpiling framework (Chapter 2, s. 2.2). GeoNorth's renewal adds $34 million for northern geoscience data.

Likely Government Intent

Chapter 1 says Canada "has fallen behind in bringing those minerals from mine to market" and sets domestic processing as the goal. The budget ties minerals to "resource sovereignty", to defence supply chains and to the target of doubling non-U.S. exports by the end of 2035. It cites more than 50 critical minerals agreements with more than 15 countries and PwC's ranking of Canada as a policy leader.

The tools reflect the fiscal plan. The write-offs and the starred minerals row count as capital investment, and Crown financing such as the Accelerator has no cost line at all. This suggests the government prefers support it can book as capital or keep off the balance to new grant programs, which would count against the operating anchor.

The Brief puts $2.3 billion of new funding against the Critical Minerals Strategy and says it builds on a $5 billion strategy. Chapter 1's net five-year row is $1,348 million. The budget does not reconcile the two, which likely reflects credit costs after 2030-31.

Open Questions

1. Did the Canada Critical Minerals Accelerator replace Budget 2025's Critical Minerals Sovereign Fund, and what happened to the First and Last Mile Fund? NRCan and Finance hold the answer, and it decides whether equity and offtake support still exist outside EDC.
2. What produces the $113 million in projected revenues in the minerals row? Finance and NRCan can say, and repayable terms would change the value of strategy funding to a project.
3. Will feasibility-study costs get any tax route after Bill C-31? Finance's Tax Policy Branch holds it, and those costs are large for developers moving to a construction decision.
4. How much federal money, if any, goes to Grays Bay Road and Port and to Ring of Fire access? The Major Projects Office at the Privy Council Office and Ontario hold the split of the $6.1 billion, and corridor funding decides which deposits become mines.
5. How will the BDC and EDC transition board treat the Accelerator's mandate and risk appetite? Finance appoints the board, and the budget expects financing Crown corporations to take more risk than private lenders.

Key Dates

Suggested Message Frames

1. For government. "Five more years of exploration credits, worth $956 million, keep junior financing open to March 31, 2032, and feasibility-study costs are the unfinished business." The supporting figures are the $307 million peak in 2027-28 and the Bill C-31 exclusion.
2. For investors. "Mine development costs become 100 per cent deductible under the Productivity Mega Deduction, up from 30 per cent, which raises after-tax returns on build decisions taken now." The supporting figure is Chart 1.2's 8 per cent gain in after-tax returns for oil, gas and mining.
3. For members and media. "The budget restates $500 million for Red Chris and $2 billion for the Accelerator, while new minerals program money is $424.4 million over four years from 2027-28." The supporting figure is the -$11 million net cost of the minerals row in 2026-27.

Opposition and Media Narratives to Anticipate

The Conservatives will frame mining support inside a $62.3 billion deficit and argue that faster approvals matter more than credits. They will likely welcome the write-offs. The Bloc Québécois will press its phosphates ask for Saguenay–Lac-Saint-Jean and point to Matawinie and Bécancour.

Indigenous organisations will test Bill C-39's one-year clock against the duty to consult. The budget states the timelines "do not change section 35 rights". The Registered Nurses' Association of Ontario has already asked that project decisions uphold free, prior and informed consent.

Mining reporters will note the absent Sovereign Fund and the gap between the Brief's $2.3 billion and the chapter's $1,348 million. Ontario coverage will focus on the Ring of Fire share of the $6.1 billion, which the budget does not break out. The Parliamentary Budget Officer may ask for the cost of extending the credits beyond 2030-31.

Data Points to Monitor

• Flow-through financings and credit claims against the $307 million projected for 2027-28.
• Bill C-31's CEE clause and Bill C-39's progress through committee.
• NRCan's 2027-28 Main Estimates for the strategy renewal and any repayable terms.
• Accelerator and Canada Growth Fund deal announcements, and the first EIB investment under the treaty framework.
• The BDC and EDC transition board's mandate, and Canada Strong Fund legislation.
• Counter-tariff relief, with $8.9 billion of $14.1 billion assessed remitted or relieved since March 2025 (Budget 2026: Masters of Our Destiny, Annex 1).
• The exchange rate against the 72.1 US cents assumed for 2026, and the spring economic update.
