CUSMA’s 2026 Review in Canada

Canada’s most important trade relationship reached a defining milestone on July 1, 2026, when the Canada-United States-Mexico Agreement (CUSMA) underwent its first mandatory Joint Review, exactly six years after the deal replaced NAFTA. Built into the agreement from the start, this review required all three countries to confirm in writing whether they wanted to extend CUSMA for another 16 years, through 2042. Canada and Mexico both formally confirmed their support for extension, while the United States, represented by U.S. Trade Representative Jamieson Greer, declined to renew the agreement in its current form, a decision that shifts CUSMA into a new, less predictable phase without ending the agreement itself.

This report lays out the most current, verified CUSMA review statistics for Canada in 2026, sourced exclusively from Global Affairs Canada, the Office of the United States Trade Representative, and the Prime Minister’s Office. Readers will find figures on the scale of trade CUSMA governs, how the July 1 review actually unfolded, the tariff measures already reshaping cross-border commerce, and what happens next under the newly triggered annual review process. Every number reflects the latest published federal data, giving exporters, manufacturers, and policymakers a single reliable reference point on where North American trade truly stands after this landmark review.

Understanding this moment requires separating two distinct but overlapping storylines. The first is the formal CUSMA Joint Review itself, a structured, treaty-mandated process with defined legal outcomes and timelines. The second is the broader, more turbulent landscape of unilateral U.S. tariff actions that have been imposed under separate legal authorities entirely, some of which respect CUSMA’s preferential treatment and some of which do not. Both storylines matter enormously to Canadian businesses, and this article addresses each in turn using only verified government sources.

Interesting Facts About the CUSMA 2026 Review in Canada

Before the detailed breakdown, here is a quick-reference table of standout figures defining this year’s review.

These figures capture both how deeply integrated the North American economy has become under CUSMA and how much uncertainty now surrounds its future path. Trade between Canada and its CUSMA partners has grown 39%, or $741 billion, since the agreement replaced NAFTA in 2020, with roughly C$3.5 billion in goods and services crossing the Canada-U.S. border every single day in 2025. Despite this deep integration, the July 1, 2026 review ended without the unanimous extension Canada and Mexico both sought, triggering a new phase of annual reviews rather than a clean 16-year renewal.

The stakes behind this outcome are amplified by Canada’s structural trade dependence on the United States, with roughly 75% of Canadian exports flowing south of the border compared to just 30% of American exports moving in the opposite direction, a leverage imbalance that shaped much of the negotiating dynamic leading into the review. Layered on top of the review itself, Canadian exporters are already navigating a complex patchwork of U.S. Section 232 tariffs on steel, aluminum, and copper ranging from 15% to 50%, tariffs that apply regardless of CUSMA compliance status, showing that the trade relationship’s challenges extend well beyond the review process alone.

What Happened on July 1, 2026: The CUSMA Joint Review

July 1, 2026 Review Outcome by Country
Canada: Support Extension     ████████████████████████████████████████ Confirmed
Mexico: Support Extension     ████████████████████████████████████████ Confirmed
United States: Declined       ██████████████████████████████████████░░ Not Confirmed

Source: White & Case LLP, “USMCA 2026 Joint Review: United States declines to extend Agreement, triggering annual reviews,” July 2026, citing USTR and Global Affairs Canada statements.

The Free Trade Commission, comprising Canada’s Minister Dominic LeBlanc, U.S. Trade Representative Jamieson Greer, and Mexico’s Secretary of Economy Marcelo Ebrard, held its mandatory six-year review virtually on July 1. Both Canada and Mexico had formally signaled their intent to renew CUSMA before the meeting even took place, with Canada submitting formal written recommendations to its trading partners on June 1, 2026. The United States, by contrast, stated it “did not agree to renew the USMCA in its current form,” a position that had been previewed through weeks of bilateral negotiating rounds between American and Mexican officials in the lead-up to the deadline.

Critically, this outcome does not mean CUSMA has expired or lapsed. Under Article 34.7.1, the agreement carries a 16-year term running through July 1, 2036, and the option for a full extension remains available at any future point if all three governments confirm it in writing. What changed on July 1 is procedural: rather than a single confirmed 16-year extension, CUSMA now enters a cycle of mandatory annual reviews for the remainder of its current term, giving the United States a recurring yearly opportunity to press for further concessions on issues like market access, dairy quotas, and rules of origin.

Minister LeBlanc’s public statement following the meeting emphasized continuity rather than crisis, describing Canada’s position as reaffirming “unwavering support” for the agreement and noting that CUSMA “supports millions of jobs across North America” while providing Canadian businesses with “secure and predictable access” to two of the country’s most important trading partners. This framing reflects Canada’s broader negotiating posture throughout the review process: rather than treating the U.S. decision not to extend as a rupture, Canadian officials have consistently characterized it as one step in an ongoing, multi-year process, with further trilateral and bilateral engagement expected in the weeks and months following the initial July 1 meeting.

The sheer scale of commerce riding on CUSMA’s continued stability is difficult to overstate. The agreement underpins roughly US$2 trillion in annual trade across all three countries, with the automotive sector alone representing up to US$120 billion of that total, an industry defined by vehicles and parts crossing the Canada-U.S.-Mexico borders multiple times during a single assembly process. Investment flows are just as deeply intertwined as trade in goods: the United States represented 51% of all foreign direct investment stock in Canada in 2025, while Canada in turn accounted for 50% of Canadian Direct Investment Abroad stock held specifically in the United States.

This level of integration is precisely why trade analysts describe the current review environment as carrying outsized stakes despite CUSMA remaining technically in force. Industry estimates cited by risk advisors suggest that a meaningfully weakened CUSMA could see bilateral trade contract by 20% to 30%, a scenario that would disrupt integrated supply chains built up over more than three decades since NAFTA first took effect in 1994. With automotive manufacturing, aerospace, steel, aluminum, agriculture, and semiconductors all identified as sectors where Canadian, American, and Mexican firms operate within shared production systems, the economic consequences of instability extend well beyond any single industry.

The automotive sector offers the clearest illustration of how CUSMA’s specific rules translate directly into dollar-and-cents outcomes for manufacturers. Under current U.S. tariff policy, CUSMA-compliant vehicles assembled in Canada or Mexico pay duties only on their non-U.S. content, while vehicles that fail to meet the agreement’s rules of origin face the full 25% tariff on their entire value. This gap in treatment has meaningfully increased the value of formal CUSMA compliance for automakers, creating a strong financial incentive for manufacturers to invest in meeting the agreement’s regional content thresholds even amid the broader uncertainty surrounding the review’s longer-term outcome.

Even as the CUSMA review process unfolds, Canadian exporters have spent much of 2026 navigating a separate, overlapping layer of U.S. tariff measures imposed under different legal authorities entirely. As of April 6, 2026, goods within the scope of Section 232 steel, aluminum, and copper tariffs face rates ranging from 15% to 50% on their full value, a significant escalation from the earlier approach of taxing only the metal content within a finished product. Notably, CUSMA compliance provides no exemption whatsoever from these Section 232 measures, meaning fully qualifying Canadian goods under the trade agreement can still face steep tariffs if they fall into these specific product categories.

Elsewhere, CUSMA’s protections remain more meaningful: when the U.S. imposed a global 10% tariff under Section 122 of the Trade Act on February 24, 2026, replacing the previous IEEPA-based tariffs that the U.S. Supreme Court had ruled invalid, CUSMA-compliant Canadian and Mexican exports were explicitly exempted from that new baseline levy. This distinction, some tariffs bypassing CUSMA entirely while others respect its preferential treatment, illustrates why the ongoing review carries such weight for Canadian businesses: the rules determining which of these overlapping tariff regimes applies to a given shipment are becoming increasingly complex, and the review process is one of the few venues where Canada can seek to have CUSMA’s protections broadened rather than narrowed.

Alongside the CUSMA review process, Canada has rolled out a substantial package of domestic measures designed to shield strategic industries from the fallout of U.S. tariffs while continuing to press for the agreement’s renewal. The new Buy Canadian Policy requires federal contracts and grant programs above $25 million to prioritize Canadian steel, aluminum, and softwood lumber whenever contract values exceed $250,000 for those materials, a direct effort to redirect domestic demand toward Canadian producers facing reduced access to the U.S. market.

The softwood lumber sector, which anchors a forest industry contributing more than $21 billion to GDP and supporting over 194,000 direct jobs including 11,000 Indigenous positions, has received particular federal attention, with $1.2 billion in pledged support alongside a planned 50% rail freight discount on interprovincial steel and lumber shipments beginning in spring 2026. These measures reflect a dual-track Canadian strategy: continuing to advocate for CUSMA’s full 16-year extension through the ongoing annual review process, while simultaneously building resilience against the possibility that key tariff relief does not materialize even if the broader agreement eventually survives intact.

What’s Next: The Annual Review Process Through 2036

CUSMA Timeline: Review Process and Key Dates
2026 (First Joint Review)           ████████████████████████████████████████ Completed, not extended
2027-2035 (Annual Reviews)          ████████████████████████████████████████ Ongoing
2036 (Term Expiry, if no extension) ████████████████████████████████████ Final deadline

With the 16-year extension not confirmed on July 1, CUSMA now enters a period of mandatory annual reviews that will continue through 2035, the year before the agreement’s current term is set to expire in 2036. At any of these yearly check-ins, all three governments retain the ability to agree to the full extension at once, meaning the door to a 16-year renewal through 2042 remains open even though it was not exercised at the first opportunity. The only path to an earlier end to the agreement would be a formal withdrawal by one of the three parties, which under CUSMA’s terms requires a minimum of six months’ advance notice.

In the immediate term, attention has shifted to bilateral negotiations between the United States and Mexico, with a third negotiating round scheduled for the week of July 20, 2026 in Mexico City focused on resolving outstanding issues around rules of origin, agriculture, labor, and trade in steel, aluminum, and automobiles. Canada, notably, has not been announced as a participant in that specific round, having only participated in the trilateral July 1 Commission meeting itself, a detail that underscores how the post-review negotiating dynamic may increasingly play out through separate bilateral tracks rather than a single unified trilateral process. For Canadian exporters and manufacturers, this means the coming months will likely bring continued incremental developments rather than a single decisive resolution, reinforcing why close monitoring of both the CUSMA review process and the separate tariff landscape remains essential through the rest of 2026.

For businesses operating across the Canada-U.S.-Mexico border, the practical guidance emerging from this review is notably consistent across legal and trade advisory firms: no immediate operational changes are required as a direct result of the July 1 outcome, since CUSMA’s preferential tariff treatment for qualifying goods remains fully intact. However, the shift to annual reviews introduces a recurring point of uncertainty each year going forward, and firms with significant cross-border exposure are being advised to strengthen their origin documentation, valuation records, and transfer pricing support in anticipation of potentially heightened scrutiny during future review cycles. This blend of near-term stability and longer-term uncertainty is likely to define the North American trade relationship for the remainder of CUSMA’s current term running through 2036.
