Federal Budget 2026: Big Bank Stakeholder Brief

Executive Summary

1. The $0 cap on consumer liability for unauthorised account access moves those losses onto banks, and if the $704 million reported in 2025 is 5% to 10% of actual fraud, total losses run about $7.0 billion to $14.1 billion a year (calculated), with no estimate of the share banks will carry.
2. Raising the widely held threshold from $12 billion to $25 billion in equity lets a closely held challenger grow to more than twice (calculated) today's limit before it must sell down to the public.
3. A $250,000 deposit insurance limit with no limit on eligible registered and tax-free deposits removes much of the safety edge the largest banks hold with large savers, and the budget prints no estimate of the premium cost.

Top 5 Relevant Budget Measures

Anti-fraud. The framework requires financial, telecom and digital platform firms to "prevent, detect, disrupt, and respond to fraud" and to resolve complaints across sectors (Budget 2026: Masters of Our Destiny, Chapter 5, s. 5.3). The Bank Act would cap consumer liability at $0 for any transaction from unauthorised access to an account, absent gross negligence. Draft legislation goes to consultation first, and the Strategy's details come in 2027. How gross negligence is defined will set the size of the bill for banks.

AML supervision. Annex 3 moves AML/ATF supervision of federally regulated financial institutions from FINTRAC to OSFI, "to enhance the anti-money laundering and anti-terrorist financing supervision and compliance of the largest financial institutions." Chapter 5 describes only better information sharing between the two. This suggests OSFI examiners, who already set capital and liquidity rules, will also grade AML programs. That raises the stakes of an AML finding for a bank's wider supervisory standing.

OSFI's competition objective. The OSFI Act would add a secondary objective covering "proportionality, compliance burden, and market impacts" (Budget 2026: Masters of Our Destiny, Chapter 1, s. 1.5). Annex 3 adds "statutory interpretive principles." OSFI has already lowered the Domestic Stability Buffer for the largest banks. The new objective could support further easing, and it gives challengers a legal footing to seek lighter rules.

Deposit insurance. The CDIC limit rises to $250,000, with temporary high-balance cover for events such as a home sale (Budget 2026: Masters of Our Destiny, Chapter 1, s. 1.5). Large depositors who now spread money across institutions, or keep it at the largest banks for safety, get the same protection at a credit union or digital bank. CDIC premiums are charged on insured deposits, so the largest banks may pay more under the higher limit.

Challenger ownership. Foreign bank subsidiaries under $8 billion in equity can skip the 35% public holding requirement if the parent is widely held and listed. The threshold for becoming widely held rises from $12 billion to $25 billion (Budget 2026: Masters of Our Destiny, Annex 3). That keeps controlling owners in place for mid-sized banks longer, which helps them raise capital and make acquisitions.

Fines and penalties are the one costed line aimed at banks. The package raises OSFI's maximum penalties and books $186 million over four years from 2027-28 across all statutes. Higher tax penalties account for $117 million of that, which leaves about $69 million (calculated) from OSFI, the FCAC and other regulators combined (Budget 2026: Masters of Our Destiny, Chapter 6, s. 6.3). The expenditure review page covers the package.

Asked For vs. Delivered

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

The lending-side asks that cost little got through, and the tax and savings-product asks did not. Higher limits for securitization and private mortgage insurance were already in Bill C-31, so the budget does not count them as new. National Bank's call for a full tax rewrite now rests on the Spring Economic Update 2027 tranche.

Risks

Fraud liability. The $0 cap covers "any form of transaction resulting from unauthorised access." Authorised scams, where a customer is tricked into sending money, appear to fall outside that wording. The framework's cross-sector complaint duty may still pull them in. Banks will want the consultation to set clear lines for gross negligence and for telecom and platform responsibility.

One supervisor for prudential and AML. Moving AML/ATF supervision to OSFI joins two exam regimes. OSFI's administrative penalties are also being strengthened, and the OSFI Act gets a statutory basis for actuarial cost recovery (Budget 2026: Masters of Our Destiny, Annex 3). The budget gives no transition date or cost.

National security divestiture. The Minister of Finance could order a bank, bank holding company or foreign bank affiliate to sell an investment in a Canadian business if national security concerns emerge after review (Budget 2026: Masters of Our Destiny, Annex 3). Merchant banking, venture and infrastructure stakes carry a new exit risk. The budget does not say what triggers the power.

Competition pressure. The OSFI objective, the $25 billion threshold, a one-year clock for new-entrant decisions and a ministerial statement on credit union continuance all favour new rivals. Deposit insurance at $250,000 lets them compete for large balances.

Conduct rules. Regulations will require an annual statement of account fees. The government will consult on applying credit card payments to the highest-interest balance first, as in Quebec, and on prepayment penalty transparency for insured mortgages (Budget 2026: Masters of Our Destiny, Chapter 3, s. 3.2 and s. 3.3). The Bank of Canada will publish insured mortgage rates. Branch closures will require online notices and fee waivers (Annex 3). Each one cuts fee income or makes pricing easier to compare.

Fiscal backdrop. The deficit is $62.3 billion in 2026-27, and gross borrowing rises to $611 billion in 2027-28 (Budget 2026: Masters of Our Destiny, Annex 2). The 10-year bond yield is assumed at 3.6% in 2026 and 3.8% in 2027 (Annex 1, Table A1.2). Heavy issuance supports trading and dealer revenue. It also competes with bank bond issues for investor demand.

Opportunities

Distribution. Canada Strong Notes launch in 2027 through "participating financial institutions" (Budget 2026: Masters of Our Destiny, Chapter 2, s. 2.1). The Canada Strong Fund receives $25 billion over three years and co-invests with private investors. The Crown corporations page covers the Fund's structure. The budget does not set fees for selling the notes.

Mortgages. Optional mortgage insurance rises to a $1.5 million price limit with 30-year amortisations for first-time buyers or new builds. From February 1, 2027, three- and four-unit new builds can get insured construction financing up to 90% of value, and private insurers can cover five- to fifty-unit buildings (Budget 2026: Masters of Our Destiny, Chapter 3, s. 3.2). The CRA income verification service gives lenders a fraud check, with industry funding expected after the pilot. Financial requirements for 2027-28 include up to $30 billion for Canada Mortgage Bond purchases (Annex 2).

Defence and project finance. The chapter cites CIBC's $2 billion for defence and dual-use SMEs and Scotiabank's Canadian Defence Issuance Framework (Budget 2026: Masters of Our Destiny, Chapter 5, s. 5.1). The Defence, Security and Resilience Bank will be headquartered in Canada and operate from 2027. A AAA-rated lender at home creates syndication and advisory work. The airport concession model and wider infrastructure rules for life insurers add project-finance pipelines.

Payments. Real-Time Rail launches November 9, 2026, and the next payments consultation comes in early 2027. Bank of Canada oversight of payment service providers is also being strengthened (Budget 2026: Masters of Our Destiny, Chapter 1, s. 1.5). The Bank of Canada will be able to provide emergency lending in foreign currencies (Annex 3).

Tax administration. Large financial institutions can get GST/HST input tax credit allocation methods pre-approved for three fiscal years, for fiscal years beginning after June 30, 2027. The CRA will be able to report tax debts over $50,000 to credit bureaus after royal assent, which adds data to credit files (Tax Measures: Supplementary Information).

Likely Government Intent

The government wants more competition in banking and says the sector "would benefit from being a more competitive market." It promises "more choice, lower prices, and greater access to innovative financial services." It also wants bank capital and distribution behind its projects. The budget credits the lower Domestic Stability Buffer with freeing capital "that can be deployed in support of the Canadian economy." Placing fraud, AML and national security duties on banks fits the budget's affordability and sovereignty themes and adds almost nothing to its cost.

Open Questions

1. Gross negligence and shared liability. The Department of Finance's draft fraud legislation will define what customers must do and how telecoms and platforms share losses. Those terms decide most of the $0 cap's cost.
2. The AML transition. Neither the date nor the cost of moving supervision from FINTRAC to OSFI is given. OSFI and Finance hold the plan, and OSFI's assessments on institutions will show who pays.
3. CDIC premiums. The budget gives no premium estimate for the $250,000 limit or the registered-account change. CDIC sets the premium rules that decide how much the largest banks pay.
4. Canada Strong Notes terms. Finance and the Fund have not said which institutions will sell the notes or on what fees and capital treatment.
5. Divestiture triggers. The Minister of Finance's office holds the criteria and review process for the national security power, which affect the value of bank equity stakes.

Key Dates

Suggested Message Frames

For government. Banks and telecoms launched the Cross-Sector Anti-Fraud Exchange in October 2026. A $0 liability rule protects customers best when telecoms and platforms carry matching duties, against $704 million in reported losses.

For investors and business media. OSFI's lower Domestic Stability Buffer freed capital for lending, and banks are using it. CIBC's $2 billion for defence and dual-use SMEs is in the budget's own text.

For customers and consumer media. A $250,000 deposit limit protects savers at every institution. Large banks will compete for those deposits on price and service under the same rules.

Opposition and Media Narratives to Anticipate

The NDP and the Bloc Québécois will treat the annual fee statement, the credit card allocation consultation and the $0 cap as overdue. They will say the budget still leaves bank fees and profits alone. Consumer groups will press for authorised scams to fall under the cap.

Conservatives are likely to attack the deficit, at $62.3 billion in 2026-27, and $60.2 billion in public debt charges (Annex 1, Table A1.8). They may also question Canada Strong Notes as government borrowing sold through banks. Credit unions and challenger banks will praise the threshold and deposit insurance changes. The business press will read them as a turn against the incumbents.

The Parliamentary Budget Officer is likely to examine Canada Mortgage Bond purchases and the $611 billion borrowing program. Provinces will watch the payments rules, which call for harmonised consumer protection for payment service providers with the provinces and territories.

Data Points to Monitor

• Rates. The 3-month treasury bill is assumed at 2.3% in 2026 and 2.6% in 2027, and the 10-year bond at 3.6% and 3.8% (Annex 1, Table A1.2). Margins and mortgage renewals depend on that curve.
• Credit quality. Unemployment is projected at 6.6% in 2026, falling to 6.2% in 2027.
• Draft fraud legislation and CDIC Act amendments, for liability definitions and premium effects.
• OSFI's capital decisions under the new competition objective, including any further change to the Domestic Stability Buffer.
• Treasury bill and bond issuance against the $611 billion 2027-28 plan and the Canada Mortgage Bond purchase amount.
• The Spring Economic Update 2027, for the second tax simplification tranche and Canada Strong Notes terms.
