Can the United States block a Canadian trade deal under Article 32.10?
Prime Minister Mark Carney said on August 22 that U.S. negotiators had introduced language seeking to restrict Canada's ability to execute other trade deals. The Government of Canada video of Prime Minister Carney's August 22 press conference on the response to U.S. tariffs supplies the statement, but not the proposed clause. No U.S. term sheet, draft legal text, or side letter has been made public. That missing text limits what can be said about the failed negotiation.
The current USMCA Article 32.10 is not a U.S. approval rule. It applies to an FTA with a country that meets a two-part definition. Before negotiations and signature, respectively, it requires notice, requested information sharing, and text review. Paragraph 5 then says that "Entry by a Party into" a covered FTA allows the other two parties to terminate USMCA on six months' notice and replace it between themselves with a bilateral agreement. The clause contains no vote on whether Canada may sign.
Nothing in the public record yet supports a partner-specific Article 32.10 memo. It identifies no prospective partner, qualifying FTA instrument, or covered negotiating stage, and Carney's August 22 statement changes neither tariff treatment nor USMCA eligibility.
That changes when an official record identifies a partner, an agreement intended to be an FTA, and a decision to begin negotiations. Counsel should then test both parts of the country definition and preserve any unresolved facts. If either part fails, or the contemplated instrument is not an FTA, Article 32.10 does not apply. Because notice is due at least three months before talks begin, the file should open at the negotiating stage, not at signature or entry into force.
Separate from that question, 50% Section 338 duties took effect at 12:01 a.m. eastern time on August 22, 2026, on articles the product of Canada covered by HTSUS 9903.03.12 through 9903.03.14. Entry teams must review Proclamations 11046, 11047, and 11048, as amended by Proclamation 11056, together with CBP CSMS 69606660 on Section 338 tariffs on Canadian goods and its HTS attachment. Article 32.10 coverage decides neither ordinary nor preferential tariff eligibility, and USMCA qualification alone does not answer liability under a separate additional-duty measure. The entry file must test HTS coverage, origin and qualification, entry date, exclusions, and the operative CBP instructions. Canada has announced countermeasures for September 8, but had not published the new product list at the research cutoff.
What Article 32.10 does at each stage
The table is current through August 24, 2026 and covers the public agreement text.
Stage
Trigger
Required action or available right
What changes the conclusion
Ordinary third-country activity
The partner fails either part of the non-market-country definition, or the instrument is not an FTA
Article 32.10 supplies no process duty on that record
Evidence that the partner satisfies both definition limbs and the instrument is an FTA
Before covered negotiations
A party intends to begin FTA talks with a defined non-market country
Inform the other parties at least three months before negotiations begin
A different start date or an instrument outside the FTA category
Objectives-information request before commencement
Another party requests information from a party intending to commence covered FTA negotiations
Provide as much information as possible regarding the objectives
The request, its date, and the information provided
Before signature
A party intends to sign the covered FTA
Give the other parties an opportunity to review the full text, annexes, and side instruments no later than 30 days before signature
A change in the planned signature date or agreement text
Paragraph 5 trigger
The treaty says "Entry by a Party into" the covered FTA. Canada's implementation statement describes the FTA entering into force
The other two parties may terminate USMCA on six months' notice and replace it between themselves with a bilateral agreement
The conclusion, approval, and entry records, an actual notice, and the bilateral text
Broader restraint on Canadian trade deals
New language reaches beyond the current definition or remedy
The legal instrument and approval path control
Publication of an amendment, side agreement, implementing measure, or other operative text
The timing matters. Process duties arise before signature. The exit option is tied to paragraph 5's "Entry by a Party into" language, which Canada's implementation statement reads as the covered FTA entering into force.
The partner and instrument control the file
The definition is conjunctive. Limb (a) expressly asks whether, on November 30, 2018, a USMCA party had determined that the prospective partner was a non-market economy for purposes of its trade-remedy laws. Limb (b) asks whether any USMCA party has signed an FTA with that country.
The Global Affairs Canada statement on CUSMA implementation reads limb (b) at the time CUSMA was signed. It says the provision does not apply to CPTPP parties because a USMCA party had already signed an FTA with them then. The statement also notes that Canada does not maintain a general list of non-market economies and may instead make sector-specific findings in antidumping investigations.
Counsel therefore needs a dated record for both limbs. A government's current view that a partner uses non-market policies cannot replace the first condition. For the second, preserve the date of every potentially disqualifying FTA signature and the Canadian implementation statement's reading. Failure on either point closes the Article 32.10 inquiry under the current text.
The instrument matters as much as the partner. A security partnership, sector arrangement, investment memorandum, or tariff-alignment measure does not become an Article 32.10 FTA merely because it affects commerce. The negotiating mandate or another official record must identify the legal form.
Preserve the dated official record for each point: the trade-remedy determination in force on November 30, 2018, the relevant FTA signature and date, and the mandate or notice identifying the new negotiation as an FTA. A general country-risk label cannot supply a missing treaty trigger.
In the Government of Canada text of Prime Minister Carney's August 22 prepared remarks on Canada-U.S. trade negotiations, Carney said Canada would keep expanding trade relationships, including prospective deals involving ASEAN and India. The public U.S. account identifies no partners, covered instruments, or definition for the rejected language. None of those Canadian negotiations can be placed inside the reported restriction from the current record.
Disclosure carries pressure without an approval vote
For a covered negotiation, the three-month notice arrives before talks begin. Objectives must be shared only if another party asks, and the duty is to provide as much information as possible. Full text, annexes, and side instruments must be available for review as early as possible and no later than 30 days before signature.
Those duties can expose an origin rule, transshipment route, state-enterprise provision, or market-access commitment that the other parties believe would erode USMCA. They also give the other governments time to press for changes. Yet the operative verbs are inform, provide information, and provide an opportunity to review. Article 32.10 never says approve, consent, or authorize.
The political pressure can still be substantial. A government considering a covered FTA knows that the other two parties will see the text and may later reconstruct USMCA without it. For a company, the clean explanation is that the clause raises agreement-level risk without changing a customs rate when negotiations are announced.
Termination and replacement require further acts
Paragraph 5 says "Entry by a Party into" a covered FTA, while Canada's implementation statement reads that phrase as entry into force. Counsel should therefore track signature, domestic approval, and entry into force separately. If the trigger is met, the other two parties may give six months' notice, review which USMCA provisions need adjustment, and carry the rest into a bilateral replacement. Under paragraph 8, that agreement enters into force 60 days after the last bilateral party reports completion of its domestic procedures.
Nonrenewal at a six-year review also starts no six-month clock. Article 34.7 sends the parties into annual reviews for the rest of the current term unless all later confirm a new 16-year extension. The review provides a negotiating forum, but it does not amend the agreement by itself.
Why a preference chain cares before duties change
For a business using Canadian inputs or production, the immediate risk is continuity of the agreement that supports the preference claim. If the paragraph 5 trigger is met, Washington and Mexico gain a treaty option whose exercise could terminate USMCA and replace it with a U.S.-Mexico bilateral agreement to which Canada is not a party. The commercial response would then depend on the notice, the bilateral text, the countries' implementing measures, and the effective dates attached to them.
An early Article 32.10 notice deserves attention because it can begin a record that later affects the availability of USMCA preferential treatment for a chain relying on Canadian production. A notice, signature, or press report neither changes the country of origin of a good nor removes preference by itself. Current claims remain governed by USMCA until an operative instrument changes their treatment.
Counsel should therefore connect the exposure memo to the company's origin file without merging them. The memo tracks the partner, instrument, treaty stage, and government notices. The origin file continues to hold classification, certification, regional-value-content support, and the production facts used for the current claim. If the other parties exercise paragraph 5, the resulting text and domestic instructions will show which origin assumptions need to be retested. Until then, the memo is a watch file rather than a new customs position.
A wider restraint would need its own legal container
If the rejected language required Canada to obtain U.S. consent before concluding a wider class of trade deals, covered ordinary market economies, or created a right to block signature, it would reach beyond Article 32.10. Negotiators could seek such a rule, but its legal container would determine its effect.
The clearest route into USMCA is Article 34.3. The parties may agree in writing to amend the agreement. The default effective date is 60 days after the last party gives written notice that it approved the change under its applicable legal procedures, unless the parties choose another date.
A separate bilateral agreement could also contain new promises. Its effect would depend on the text, the authority used to conclude it, the domestic steps required in each country, and the remedy for breach. A political statement could announce intent without producing the same legal consequence. A tariff proclamation could alter covered entries without changing Article 32.10.
The sectoral alignment discussed during the same press conference belongs in that separate analysis. Carney said Canada saw merit in some coordination involving auto, steel, aluminum, non-market economies, and transshipment, then described the reported trade-deal restriction as another issue. The USTR August 21 public statement on the Canada negotiations also listed external-tariff alignment among the proposed areas of cooperation, but published no term sheet.
The USTR 2026 Trade Policy Agenda seeks stronger origin rules and measures addressing non-market investment, overcapacity, transshipment, and offshoring. Those goals can support aligned tariffs or common screening in selected sectors. They do not rewrite Article 32.10 without operative text. Traverse has already shown why USMCA does not turn three tariff schedules into one.
The records that would change the analysis
The file should move only when an official record establishes legal form or scope: a negotiating mandate, paragraph 2 notice, request for objectives, pre-signature text, approval record, entry-into-force notice, paragraph 5 termination notice, or bilateral replacement text. Publication of the alleged broader restriction, whether as an Article 34.3 amendment or a side instrument, belongs in the same chronology. The USTR Ambassador Greer's July 1, 2026 statement on the USMCA Joint Review supplies none of those records.
A term sheet or draft would show whether the proposal reaches FTAs alone, requires consultation or consent, coordinates tariffs, or creates a remedy for breach.
The public treaty text lets Washington and Mexico apply pressure through disclosure and a conditional exit. It gives the United States no standing vote on Canada's trade agreements. Until the rejected language is published, the reported demand belongs in a monitored negotiating file, not in the treaty text.
