An analysis of the benefits and costs of the agreement entering annual review, written from the perspective of Canada’s agriculture and agri-food portfolio – July 1, 2026
Executive Summary
On July 1, 2026 – the sixth anniversary of the Canada-United States-Mexico Agreement’s entry into force – the mandated joint review under Article 34.7 concluded without the unanimous confirmation needed to extend the agreement for a fresh sixteen-year term. United States Trade Representative Jamieson Greer confirmed that the United States did not agree to renew CUSMA in its current form, citing “structural shortcomings” – and in the American telling of the story, Canadian dairy sits near the very top of the list of those shortcomings. Canada, through Minister Dominic LeBlanc, reaffirmed its support for the agreement and its renewal; Mexico did the same. Under the treaty’s architecture, one holdout is enough. CUSMA now enters a decade of annual joint reviews, remaining in force until its scheduled expiry on July 1, 2036 unless extended at a future review – or terminated earlier through the six-month withdrawal clause in Article 34.6.
No sector of the Canadian economy experiences this outcome as unevenly as agriculture. The portfolio splits into two constituencies whose interests point in nearly opposite directions. On one side sit the export-oriented sectors – beef, pork, canola, grains, oilseeds, pulses, maple syrup, processed foods – for whom CUSMA is, in the words of the Canadian Agri-Food Trade Alliance, one of the best agreements in the world, and for whom every year of uncertainty is a year of eroded market position. On the other side sit the supply-managed sectors – dairy, poultry, eggs – for whom the joint review was never an opportunity but a siege, and for whom non-renewal, paradoxically, may represent a form of victory: the review closed without Canada making the dairy concessions Washington demanded.
This article works through what non-renewal actually means in legal and commercial terms, and then examines the negatives and the genuine benefits from the standpoint of Canadian agriculture as a whole – farm gate to processor to exporter – recognizing throughout that “Canadian agriculture” is not one interest but a coalition of interests that the annual review era will repeatedly test.
Part I: What Actually Happened – The Legal Mechanics of Non-Renewal
The sunset architecture
CUSMA was built to expire. At American insistence during the 2017–2018 renegotiation of NAFTA, Article 34.7 embedded a sixteen-year sunset: the agreement terminates on July 1, 2036 unless renewed. To forestall expiry, the parties were required to conduct a joint review on the sixth anniversary – July 1, 2026 – at which each government had to confirm in writing its desire to continue. Unanimous confirmation would have reset the clock to 2042, with the next review in 2032.
That confirmation did not come. The consequence is not termination but a change of state: the agreement remains fully in force, with preferential tariff treatment, dispute settlement, and all chapters operative, but the parties must now conduct joint reviews annually through 2036. At any annual review, a sixteen-year extension can still be agreed. Trade lawyers spent the spring emphasizing that July 1 was never a legal cliff – and for agriculture specifically, nothing changed at the border on July 2 that was not already true on June 30.
The withdrawal wildcard
Article 34.6 permits any party to withdraw on six months’ written notice, with the agreement continuing between the remaining two. University of Ottawa professor Patrick Leblond has made the uncomfortable but important point that the notice period is, in practice, only as binding as Washington chooses it to be: an administration could simply stop applying the agreement and dare its partners to litigate. Arbitrators would likely rule against the United States and authorize retaliation, but Canada and Mexico would still face the practical question of whether and how to retaliate against a customer that dwarfs them. For agriculture, whose perishable products and just-in-time livestock logistics cannot tolerate even brief border disruption, this asymmetry between legal rights and practical remedies is not academic.
The dairy siege that shaped the review
To understand agriculture’s position on July 1, one must understand the eighteen months that preceded it. The United States entered the review process having made Canadian dairy a named, structural grievance. USTR Greer explicitly tied any sixteen-year extension to fixes for “specific and structural issues,” placing Canada’s dairy policies near the top. Roughly eighty members of Congress from both parties wrote to Greer urging him to hold Canada accountable on dairy commitments during the review. A U.S. International Trade Commission investigation into Canadian dairy pricing and quota practices reported its findings in March 2026, three months before the review – timing that handed Washington a fresh evidentiary brief on the eve of negotiations.
The mechanics of the grievance sit inside tariff-rate quotas. Under CUSMA, the United States is entitled to tariff-free access equivalent to roughly 3.5% of the Canadian dairy market through TRQs; imports beyond those volumes face over-quota tariffs reaching approximately 300% on some products – a wall high enough to block trade in most circumstances. American exporters and politicians allege that Canada administers the quotas to frustrate their use, pointing to average fill rates that have ranged between 27% and 39% in recent years and to the concentration of quota allocation in the hands of Canadian processors rather than retailers and food-service buyers closer to the consumer. Two CUSMA dispute panels have already fought over this ground: the first, in January 2022, found Canada’s processor-exclusive allocation pools inconsistent with its obligations and forced revisions; the second, concluding in late 2023, upheld Canada’s revised system. Canada thus met the letter of its commitments while preserving the intent of supply management – a legal victory that did nothing to reduce American political fury, and arguably intensified it.
Canada, meanwhile, entered the review with its own hands deliberately tied. Parliament passed legislation prohibiting federal negotiators from granting any additional market access for supply-managed products in trade negotiations – a law with overwhelming political support, championed as protection against farmers being traded away as they were, incrementally, in CETA, CPTPP, and CUSMA itself. Prime Minister Carney publicly stated that supply management would not be on the table. Dairy Farmers of Canada estimates that the combined access already granted under those three agreements is equivalent to 8.4% of Canadian milk production, representing average annual revenue losses to farmers of roughly $450 million – losses the federal government has partially offset with compensation packages, including $1.75 billion over eight years tied to CETA and CPTPP.
The result was an immovable object meeting an unstoppable force. Washington demanded structural dairy concessions as the price of renewal; Ottawa was legally and politically incapable of paying it. Non-renewal was, in that light, the predictable outcome – and Canadian agriculture must now live in the world it creates.
The tariff backdrop – and agriculture’s crucial carve-out
The broader tariff wall erected since early 2025 – IEEPA-based measures, Section 232 metals tariffs at 50%, a 35% tariff on non-CUSMA-originating goods, 10% on non-originating energy and potash – largely rests on U.S. domestic authorities that sit outside the agreement. Critically for agriculture, CUSMA-compliant agri-food goods have been exempted from the general tariff measures. That exemption is the single most valuable fact in Canadian agriculture’s trade position today: it means that origin qualification under CUSMA is the difference between duty-free access and punitive tariffs for beef, pork, canola products, grains, and processed foods moving south. It also means the agreement’s continuation – even in annual-review limbo – is existential for exporters in a way that abstract debates about 2036 do not fully capture.
Part II: The Negatives – What Non-Renewal Costs Canadian Agriculture
1. The exemption now lives on an annual leash
The agri-food carve-out from U.S. tariff measures exists because CUSMA exists and because Washington has, so far, chosen to respect the agreement’s preference for originating agricultural goods. Annual reviews convert that shelter from a fixture into a hostage. Every year, the exemption is implicitly on the table; every annual review is an opportunity for the United States to demand payment – in dairy access, in regulatory alignment, in digital or industrial concessions – for its continuation. Export sectors now face a decade in which their market access can be repriced annually by a counterparty that has demonstrated both the willingness and the legal creativity to weaponize uncertainty. For a cow-calf operator planning herd expansion, a hog barn investor, or a canola crusher siting new capacity, the planning horizon that agriculture requires – biological cycles measured in years, capital cycles in decades – is fundamentally mismatched with a trade framework renegotiated every twelve months.
2. Integrated livestock and grain supply chains are uniquely exposed
North American agriculture is not two national industries that trade; it is one integrated system. Feeder cattle move from Prairie ranches to U.S. feedlots and return as boxed beef; weanling pigs born in Manitoba are finished in Iowa; corn, soymeal, and distillers grains flow north while canola oil and meal flow south; fertilizer, seed genetics, and machinery cross the border in both directions. This integration – deeper than in almost any manufactured-goods sector outside automotive – means that even the threat of disruption imposes costs. Basis levels widen, packers and processors demand risk discounts, and long-term supply contracts acquire trade-contingency clauses that shift risk onto the party with less leverage, which is usually the Canadian farmer. The withdrawal scenario, however improbable, is uninsurable for live-animal logistics: a six-month notice period would trigger immediate herd liquidation decisions that could not be reversed for years.
3. Dairy’s reprieve is a suspended sentence, not an acquittal
Supply management survived the July 1 review intact – no new access was granted, the tariff wall stands, and the domestic legislation held. But the sector would be badly mistaken to read this as final. The annual review structure means the American dairy lobby, with Wisconsin’s electoral weight behind it and the White House’s ear, gets a fresh formal opportunity every single year. The pressure will not arrive as a frontal demand to dismantle supply management – analysts note that no serious American ask targets the tariff wall itself – but as relentless, technical grinding on TRQ administration: allocation methodology, fill rates, transparency requirements, eligibility rules. Higher fill rates on existing quotas alone could bring quantities equivalent to roughly 2% of the Canadian market into the country over a visible horizon, capturing a share of market growth that would otherwise accrue to Canadian farms as quota growth. That is not the end of supply management, but it is a permanent tax on its expansion – and each annual review is a fresh chance for the grinding to produce concessions, dispute panels, or retaliatory linkage to other files.
4. The dairy shield forces other sectors to pay the toll
The legislation shielding supply management is a triumph for dairy, poultry, and egg producers and a strategic burden for everyone else in the portfolio. With supply management off the table by statute, Canadian negotiators must find their concessions elsewhere – and the sectors most likely to be conscripted are agriculture’s own exporters (through regulatory or access asks) or the manufacturing files (autos, steel, aluminum) whose tariff relief matters to the broader economy. Critics of the legislation warned precisely this: that boxing in negotiators on dairy forces yield in other sensitive areas. The internal politics of Canadian agriculture, always delicate, will be strained annually as export sectors ask why their market access carries the strategic mortgage for a system that benefits a different set of farms.
5. Perishability compresses every timeline
A machinery exporter facing tariff uncertainty can warehouse inventory, delay shipments, or re-route to another market over months. A greenhouse tomato grower, a cherry shipper, a fresh pork exporter cannot. Agricultural trade’s perishability means that policy shocks translate into losses within days, not quarters, and that contingency planning options available to other sectors simply do not exist. The annual review calendar now overlays the production calendar: a review that turns hostile in the weeks before harvest, or during peak livestock marketing, would find the sector at maximum exposure with minimum flexibility.
6. Investment in processing capacity stalls
Canada’s chronic agricultural weakness is that it exports raw commodities and imports processed value. Reversing that requires capital – crush plants, pork processing, food manufacturing – and that capital is precisely what annual-review uncertainty deters. A canola crush facility or a further-processing plant is a thirty-year asset whose economics depend on tariff-free access to the U.S. market for finished product. The Bank of Canada’s finding that roughly half of the economy’s 1.5% GDP shortfall reflects reduced potential output applies with special force here: processing investment deferred in 2026–2028 is value-added capacity, jobs, and farm-gate demand that rural Canada never gets back, even if a sixteen-year extension eventually arrives.
7. The two-front trade war problem
CUSMA uncertainty does not exist in isolation. Canadian agriculture has simultaneously been managing Chinese trade retaliation – anti-discrimination tariffs on canola meal and peas (suspended late in the period, but revocably) and duties on canola seed (reduced, not eliminated). The strategic consequence is that agriculture’s two largest export relationships have both become unreliable at once. Diversification advice that assumes a stable alternative market rings hollow when the principal alternative has itself demonstrated willingness to weaponize agricultural trade. Non-renewal of CUSMA thus lands on a sector with less strategic slack than almost any other.
8. Regulatory divergence risk grows in the dark
CUSMA’s quieter agricultural value lies in its sanitary and phytosanitary framework, biotechnology provisions, and grading and standards cooperation – the plumbing that lets an integrated food system function. A renewed agreement would have been the natural vehicle for updating these chapters around new agricultural technologies, gene editing, and pest-management alignment. Annual-review limbo freezes that modernization while each country’s regulatory systems continue to evolve separately. Divergence accumulates silently: a differing maximum residue limit here, a labelling requirement there, until compliance friction functions as a tariff that no negotiation ever formally imposed.
9. Negotiating behind Mexico – with agricultural stakes
Mexico opened formal bilateral talks with Washington in March 2026 and has worked systematically through American demands, positioning itself as the preferred partner. For Canadian agriculture, a bilateralized North America carries specific dangers: Mexico is a direct competitor in the U.S. market for beef, pork, horticulture, and processed foods. If Mexico secures bilateral arrangements – on sanitary protocols, seasonal produce, or market access – while Canada-U.S. talks drift, Canadian exporters could find themselves structurally disadvantaged against Mexican product in their most important market, inside what is nominally still a trilateral agreement.
10. Sector notes across the portfolio
Beef. The most integrated livestock trade on earth – feeders south, boxed beef both ways – depends on frictionless borders and the CUSMA exemption. Record cattle prices have cushioned the sector, and strong beef values have flowed through even to dairy incomes via cull cattle and calves; but that same price cycle means any access disruption would hit at peak herd-rebuilding decisions, magnifying long-run supply consequences.
Pork. With roughly two-thirds of production exported and a weanling trade wholly dependent on U.S. finishing capacity, hog producers carry the portfolio’s most acute withdrawal-scenario exposure. Isowean contracts and packer agreements are being rewritten with trade-contingency terms, and the sector’s CPTPP position in Japan is its most valuable hedge.
Canola, grains, and oilseeds. Canola arrives at the annual-review era already bruised by Chinese measures on seed, meal, and peas – suspended or reduced for now, but revocable. The U.S. market for canola oil (food and renewable fuel feedstock) is the growth story that CUSMA uncertainty most directly threatens, since biofuel-policy access and tariff exemption together determine crush economics on both sides of the border.
Horticulture and greenhouse. Fresh produce’s perishability and the greenhouse sector’s energy-intensive, capital-heavy model make it acutely sensitive to both border friction and any U.S.-Mexico bilateral seasonal-produce arrangements – the clearest example of Scenario C risk in the portfolio.
Fertilizer and inputs. The 10% U.S. tariff on non-originating potash makes origin qualification decisive for Canada’s flagship input export, while farmers as input buyers face imported-cost inflation on machinery and crop protection – a margin squeeze arriving from both directions.
Supply-managed poultry and eggs. Sheltered alongside dairy by statute, but strategically downstream of the dairy fight: any TRQ-administration precedent conceded on dairy becomes the template for the next American ask.
Part III: The Benefits – The Genuine Upsides of Non-Renewal
1. Supply management was not traded away
The most concrete benefit is what did not happen. Washington made dairy concessions the explicit price of renewal; Canada declined to pay, and the review closed with the tariff wall intact, no new TRQ volumes granted, and the supply management system legally and politically whole. Given that the alternative on offer was a renewal purchased with structural dairy access – a precedent that would have invited demands on poultry and eggs next – non-renewal is, from the supply-managed sectors’ standpoint, close to the best realistic outcome. Every concession Canada refused to make in June 2026 remains unspent, available to trade later only if the return – genuine sectoral tariff removal, durable exemption guarantees for agri-food – justifies it.
2. Nothing changed at the border, and the exemption held
For exporters, July 1 was anticlimactic by design. CUSMA remains in force; originating agricultural goods continue to cross duty-free; the agri-food exemption from broader U.S. tariff measures survived the review’s failure. Former officials on both sides had long signalled non-renewal was priced in. The sector’s worst-case scenarios – termination, withdrawal notice, revocation of the agri-food carve-out as review-failure retaliation – did not materialize. A decade-long runway to 2036 remains, which exceeds the planning horizon of most annual cropping decisions and many livestock cycles, even if it falls short of what processing investment requires.
3. American agriculture is Canada’s lobbyist now
A structural advantage hidden inside the annual review regime: U.S. producer groups themselves support CUSMA renewal and oppose the tariff agenda, and they are a constituency the administration cannot ignore. The Canadian Agri-Food Trade Alliance reported growing doubt about tariffs among Republicans in agricultural states during its Washington missions, and American farm organizations – direct counterparts and largely administration supporters – have been vocal that tariffs raise costs for producers and consumers alike. With midterm elections in November 2026 and polls difficult for the incumbent party, the political cost of agricultural trade disruption rises, which is precisely why analysts assess the risk of tariffs on Canadian beef, pork, and canola as lower now than a year ago. Annual reviews keep the negotiation alive into political seasons when American agriculture’s voice is loudest – a timing asymmetry that, unusually, favours Canada.
4. Annual reviews cut both ways
Under a clean sixteen-year renewal, Canada’s own agricultural irritants – U.S. country-of-origin labelling ambitions, dispute-panel compliance, sanitary barriers, and the standing softwood-style risk of technical protectionism – would have been locked out of formal renegotiation until 2032. Annual reviews give Canada a standing forum to press its asks, link files, and revisit the relationship as American politics shift. An extension concluded in 2027 or 2028, bundled with durable agri-food guarantees and negotiated when Washington’s leverage has ebbed, would be worth more to Canadian agriculture than the extension available in June 2026, which was purchasable only with dairy.
5. A forcing function for diversification and domestic value-added
Agriculture has heard diversification sermons for decades; the annual-review era finally aligns incentives with the sermon. CPTPP access to Japan and Southeast Asia for beef, pork, and canola; CETA’s underused agri-food preferences into Europe; the Indo-Pacific agreements pipeline – these move from discretionary market development to core risk management. Simultaneously, the same uncertainty that deters export-dependent processing investment strengthens the case for import substitution at home: Buy-Canadian sentiment, procurement preferences, and consumer behaviour have created the strongest domestic demand tailwind for Canadian food products in a generation. Food processors reclaiming domestic shelf space from U.S. imports in 2026–2027 are building positions defensible on service and brand long after trade tensions normalize.
6. The status quo is, for agriculture, a good status quo
Patrick Leblond’s strategic counsel – play for time, maintain the status quo, keep exporting tariff-free under the rules of origin, and avoid a rushed deal – describes agriculture’s position better than any other sector’s. Manufacturing needed the review to succeed because it needed sectoral tariff relief. Agriculture, uniquely, already has most of what it needs: the exemption. Time favours a sector whose access is intact while the counterparty’s political coalition – farm-state legislators, agricultural exporters, food-price-sensitive consumers – increasingly argues Canada’s case from within. Not making things worse is, for once, a genuine strategy rather than a euphemism for drift.
7. Clarity ends the binary
Eighteen months of renewal-or-not speculation resolved into a known state: agreement in force, annual reviews, dairy shielded by statute, exemption intact, 2036 horizon. Farm organizations, marketing boards, and processors can now converge planning on a single scenario set instead of hedging across divergent worlds. Revealed American strategy – grind on dairy, leverage the calendar, negotiate bilaterally where possible – is strategy that can be planned against.
Part IV: Scenarios for the Road to 2036
Scenario A – Extension within two to three years (moderate probability). Post-midterm political arithmetic softens Washington’s posture; a package emerges trading technical TRQ-administration adjustments (fill-rate improvements, allocation transparency – the letter of supply management preserved) plus non-agricultural concessions for a sixteen-year extension with codified agri-food exemptions. Best realistic outcome for the portfolio as a whole, though dairy absorbs incremental erosion.
Scenario B – Rolling annual limbo (high probability near-term). No extension for several years. The exemption holds but is annually contested; dairy faces yearly pressure campaigns and possible new dispute panels; processing investment stays suppressed; diversification continues. Manageable but corrosive.
Scenario C – Bilateralization (meaningful probability). U.S.-Mexico side deals reshape North American agricultural access while Canada-U.S. talks lag. Canadian beef, pork, and horticulture face preference erosion against Mexican competitors in the U.S. market. The scenario agriculture should most actively lobby against.
Scenario D – Withdrawal or de facto non-application (low probability, catastrophic impact). Six-month notice – or Leblond’s blunter scenario of Washington simply ceasing to apply the agreement – collapses the exemption and exposes agri-food exports to the full tariff wall. Perishable and live-animal trade suffers immediately and irreversibly. A tail risk warranting contingency planning, not capital allocation.
Part V: What Canadian Agriculture Should Do Now
Treat origin compliance as the whole ballgame. With the agri-food exemption contingent on CUSMA qualification, origin documentation, certification currency, and classification rigour separate duty-free access from 35% tariffs. Producers, elevators, packers, and processors should audit origin determinations annually, matched to the review calendar.
Contract for contingency. Export supply agreements need tariff-allocation clauses, trade-event renegotiation triggers, and – for livestock – logistics contingencies that acknowledge withdrawal-scenario timelines.
Keep the coalition together. The dairy-shield legislation’s cost falls on export sectors; managing that tension inside farm organizations and before government matters. A portfolio that lobbies as one – exemption preservation first, dairy defence second, modernization third – outperforms one that fragments.
Feed the American allies. U.S. producer groups and farm-state legislators are the most effective advocates for Canadian agricultural access. Cross-border industry engagement – commodity group to commodity group – should intensify ahead of each annual review and each American electoral cycle.
Fund diversification like insurance. CPTPP and CETA utilization, Indo-Pacific market development, and halal/premium positioning in third markets carry insurance value beyond commercial return. The China experience proves single-alternative diversification is not diversification.
Press for exemption codification. Canada’s core ask at every annual review should be converting the agri-food carve-out from administrative grace into binding, durable text – the one concession worth paying for.
Engage every consultation. Annual reviews mean annual consultation cycles at Global Affairs and Agriculture and Agri-Food Canada. Submissions documenting CUSMA-dependence, updated yearly with farm-level data, demonstrably shape negotiating positions.
Conclusion
July 1, 2026 delivered Canadian agriculture a paradox: the review failed, and the sector’s two halves can both plausibly claim relief. Supply management emerged unsold; exporters emerged untouched. But the annual review era converts both outcomes into rentals rather than freeholds. The dairy siege will resume every twelve months with the American lobby’s full political weight behind it; the agri-food exemption – the sector’s most valuable single asset – now lives review to review; and the investment in processing capacity that would finally move Canada up the value chain will wait for a certainty that Article 34.7 was designed never to provide again.
The sector’s advantages are real: American agricultural allies arguing Canada’s case from inside the tent, an electoral calendar that punishes food-price disruption, a status quo worth defending rather than escaping, and a decade of runway. Whether those advantages compound or dissipate depends on discipline – holding the exemption, holding the coalition, and holding out for an extension worth its price. Canadian agriculture has survived every trade era since 1989 by being simultaneously the most protected and the most export-dependent sector in the economy. The annual review decade will demand it master that contradiction as never before.
This article reflects developments as of July 1, 2026, including the trilateral Free Trade Commission meeting and the USTR’s confirmation that the United States did not agree to renew CUSMA in its current form. It is general analysis, not legal or trade advice; specific origin, quota, and market-access questions warrant professional review.
