Canada's defining trade relationship — and its greatest structural vulnerability
The United States is Canada's overwhelmingly dominant trading partner — accounting for approximately 75% of all Canadian merchandise exports and making Canada economically more dependent on a single bilateral relationship than any other OECD country. Total goods trade reached approximately $1.03T CAD in 2024 (StatCan), a figure that dwarfs every other bilateral relationship Canada has by an order of magnitude. CUSMA (Canada-US-Mexico Agreement), in force since July 2020, governs the relationship with a mandatory joint review scheduled for 2026. The relationship is simultaneously Canada's greatest commercial opportunity and its greatest strategic vulnerability: the 2025 tariff actions under President Donald Trump — including 25% tariffs on non-CUSMA-compliant Canadian goods and 10% energy tariffs — demonstrated that the US is willing to act outside the CUSMA framework, creating acute policy uncertainty. Canadian trade diversification is a long-term structural imperative that the 2025 tariff shock significantly accelerated.
Donald Trump's Republican administration, in office since January 20, 2025, holds majorities in both the House of Representatives and the Senate. Trade policy under Trump is driven by executive action — the administration has demonstrated willingness to impose tariffs outside established legal frameworks and has used "51st state" rhetoric as a bargaining posture toward Canada. The 25% tariff on Canadian goods announced in February 2025 and partially implemented represents the most significant disruption to Canada-US commercial relations since NAFTA was negotiated. The tariff environment is unpredictable: decisions are made through executive order, applied inconsistently, and can be reversed or escalated on short notice.
The 2026 CUSMA joint review is the most consequential trade policy event on Canada's near-term horizon. The US has historically used review periods as negotiating leverage. Outcomes of the 2026 review could affect rules of origin, dairy access provisions, digital trade governance, state-owned enterprise disciplines, and dispute resolution mechanisms. All five major Canadian export sectors have material exposure to review outcomes.
The US economy grew at 2.8% in 2024 — outperforming most G7 peers — driven by consumer spending, technology investment, and federal fiscal expansion. Inflation has been sticky above the Federal Reserve's 2% target, keeping interest rates elevated relative to historical norms. Moody's downgraded the US sovereign credit rating in 2025, citing fiscal trajectory concerns, though the practical impact on US borrowing costs has been limited. The US economy remains the world's largest and most dynamic by most measures.
For Canadian exporters, the US economic strength is a double-edged signal: strong US demand supports Canadian exports, but the tariff environment under the Trump administration partially offsets this advantage. Tariff costs on Canadian goods have reduced Canadian export competitiveness in sectors where substitutes are available, though integrated supply chains in energy, automotive, and aerospace make full substitution impractical.
Top 5 Canadian exports to the US: Energy (crude oil, natural gas, electricity) at approximately $230B, motor vehicles and parts at approximately $95B, consumer goods and food at approximately $65B, industrial machinery at approximately $40B, and forest products at approximately $35B. Energy dominates the export mix — stripping out energy, the goods relationship is substantially more balanced than headline figures suggest. This matters politically because US framing of trade "deficits" often ignores energy flows.
Top 5 Canadian imports from the US: Motor vehicles at approximately $65B, industrial equipment at approximately $55B, petroleum products at approximately $45B, chemicals at approximately $35B, and food and agri-food at approximately $30B. The deep integration of Canadian and American supply chains means that many "imports" are components that will be incorporated into Canadian goods and re-exported to the US, often multiple times before final sale.
Buy American provisions in US federal procurement — including expanded requirements in the Infrastructure Investment and Jobs Act and IRA — create friction for Canadian suppliers in certain sectors despite CUSMA's government procurement chapter. The practical effect is that Canadian companies bidding on US federally-funded infrastructure projects face higher US content requirements than CUSMA's general market access provisions would imply. This is a persistent and growing constraint that Canadian advocacy has not yet reversed.
The scale of Canadian business presence in the United States is without parallel in any other bilateral relationship. All of Canada's Big Five banks — RBC, TD, BMO, Scotiabank, and CIBC — have substantial US retail, commercial, and investment banking operations, with TD in particular operating as a major US consumer bank with over 1,000 US branches. Manulife Financial and Sun Life Financial both have significant US insurance and wealth management businesses operating under US brand names. Brookfield Asset Management manages more alternative assets in the United States than almost any other entity, with a portfolio spanning infrastructure, real estate, renewable energy, and private equity. Magna International employs over 100,000 people in the US through its automotive parts manufacturing network embedded in US-based OEM supply chains. Enbridge and TC Energy operate critical US pipeline and energy infrastructure that the American energy system depends upon. Shopify, despite its Canadian headquarters, derives the majority of its revenue from US merchants. CGI Group holds major US federal technology contracts. CPPIB manages one of the largest non-US institutional investment portfolios in American real estate, infrastructure, and private equity. The concentration of Canadian business interests in the US makes the relationship not simply a trade relationship but an integrated economic union — one that cannot be meaningfully separated without structural disruption to both economies.
| Risk Category | Level | Assessment |
|---|---|---|
| Political | Elevated | Trump administration has demonstrated willingness to act outside CUSMA framework via executive tariff orders; "51st state" rhetoric reflects a political posture that treats Canada as a trade adversary rather than ally. |
| Regulatory | Moderate | US and Canadian regulatory standards are broadly compatible but diverging in food safety, chemicals, and digital privacy; Canadian exporters face compliance costs that have grown over the past decade. |
| Commercial | Moderate | Strong US domestic demand supports Canadian exports; the tariff overhang creates uncertainty for capital investment decisions but has not yet caused structural exit from the US market. |
| Currency | Moderate | CAD/USD volatility is significant — the Canadian dollar weakened materially in late 2024 and 2025; most major Canadian exporters hold natural USD hedges through US-denominated revenues. |
| Supply Chain | Moderate | Border delays from tariff administration and increased customs scrutiny have added friction and cost to cross-border supply chains, particularly in automotive and agri-food. |
| Geopolitical | Low | Canada and the US remain NATO allies and Five Eyes partners; defence and intelligence cooperation has not been affected by the commercial tensions; no security risk to Canadian personnel or assets in the US. |
The United States is a low-corruption commercial environment with strong federal and state anti-bribery enforcement. Canadian companies operating in the US under CFPOA obligations face minimal incremental compliance burden — standard corporate anti-corruption policies are sufficient for most commercial engagements. The US Foreign Corrupt Practices Act (FCPA) applies to US persons and companies, not directly to Canadian companies operating in the US market, though Canadian companies with US-listed securities or US dollar clearing face FCPA-adjacent obligations. US enforcement agencies (DOJ, SEC) are highly active in global anti-bribery enforcement, and Canadian companies engaged in US-connected international transactions should maintain FCPA-aligned compliance programs.
The primary compliance considerations for Canadian companies in the US market are export controls (EAR/ITAR) and sanctions compliance (OFAC), not bribery. US state-level political donation rules and lobbying disclosure requirements require attention for companies engaged in government relations. The US is not FATF-listed. CTI rates the United States Low Compliance Risk — with the specific note that US export control and sanctions compliance (EAR/ITAR/OFAC) are critical parallel obligations for defence, technology, and dual-use product sectors.
US federal procurement is the world's largest government procurement market — estimated at over $700B USD annually. Canadian suppliers have access under the WTO-AGP and CUSMA provisions, though Buy American requirements in certain programs create friction that the agreements do not fully neutralize.
