Carney concedes Canada is “in the middle of a tariff war” as Washington negotiations sour with twelve days left before a 50 per cent duty wall rises on roughly $20 billion in Canadian goods
OTTAWA, August 8, 2026. Prime Minister Mark Carney publicly acknowledged this week that Canada and the United States are engaged in an open tariff war, hardening his language after President Donald Trump used a Las Vegas speech to call Canada and its leadership “nasty” and to threaten a further expansion of duties on Canadian exports.
Speaking to reporters on Thursday, Carney declined to soften the characterization of the negotiations that his American counterpart had offered. “This is a tough negotiation,” Carney said in French, according to an Associated Press account of the remarks. “You can say ‘nasty.’ But this is a question of Canadian jobs. It’s a question of the future of Canadian businesses.”
Carney went further, saying plainly that “we are in the middle of a tariff war with the Americans,” while noting that he laughed when asked directly about the president’s description of his government. He said Canadian negotiators were in Washington through the week and that he expected further direct conversations with Trump following a call the two leaders held the previous week.
The exchange lands at a critical moment. On August 19, additional duties of 50 per cent are scheduled to take effect on a broad list of Canadian goods under three presidential proclamations signed on July 20 that invoked Section 338 of the Tariff Act of 1930, a Depression-era authority that no American president had previously used to impose tariffs. The Office of the United States Trade Representative has said the measures will affect close to $20 billion in annual imports from Canada.
For Canadian exporters, importers on both sides of the border, and the customs brokers and freight forwarders who serve them, the practical question is no longer whether the rhetoric will escalate. It is whether the negotiating track running through Washington this month can produce enough of an agreement to suspend a duty schedule that, by the count published in the Federal Register proclamations and summarized by trade counsel, reaches across 554 tariff lines.
What Section 338 Does, And Why It Is Different
Section 338 of the Tariff Act of 1930 permits the president to impose duties of up to 50 per cent, or to bar imports outright, from a country found to be discriminating against United States commerce. The statute requires that 30 days elapse from an initial presidential announcement before the duties take effect, which is the source of the August 19 date.
Analysts at the Center for Strategic and International Studies, in a July 21 assessment by fellows Christopher Gundermann, Hugh Grant-Chapman and Diego Marroquín Bitar, described the invocation as unprecedented and noted several features that make it unusually disruptive for North American supply chains.
The most consequential of those features is that the Section 338 duties apply regardless of whether a good qualifies as originating under the Canada United States Mexico Agreement. Throughout the tariff rounds of 2025 and early 2026, Washington had generally preserved duty free treatment for CUSMA compliant goods, with the notable exception of steel and aluminum under Section 232. The Section 338 proclamations abandon that carve out. CSIS put the value of the targeted goods at $20.2 billion in 2024, equivalent to 4.9 per cent of total United States imports from Canada that year.
The proclamations are also cumulative in effect. Because the new duties stack on top of any Section 232 sectoral tariffs already applicable, the effective rate at the border for a number of covered products will exceed the 50 per cent headline figure. Trade counsel advising importers have flagged this stacking as the single most commonly misunderstood element of the measures.
The product coverage is broader than the three named grievance categories suggest. The White House fact sheet accompanying the proclamations lists wine, hockey sticks and cement among the covered goods. Practitioner summaries have identified plywood, furniture, fishing rods, seeds, apparel, wigs and swimming pools within the three lists. CSIS observed that the proclamation framed around motor vehicles does not, in fact, cover automobiles or automotive parts at all, with the exception of motorcycles, but instead reaches a large number of goods unrelated to the auto sector.
That drafting quirk matters commercially. An importer whose products bear no relationship to alcohol, dairy or vehicles may nonetheless find its classifications on one of the three annexes, and the compliance obligation attaches to the tariff line, not to the narrative in the proclamation.
The Stated Grievances
The three proclamations each rest on a distinct allegation of Canadian discrimination against United States commerce.
The first concerns provincial policies that pulled American alcohol from liquor store shelves beginning in March 2025, a response by eight of Canada’s ten provinces to the earliest rounds of American tariffs. The second concerns Canadian tariffs and quotas applied to United States motor vehicles. The third concerns the allocation of dairy tariff rate quotas under CUSMA and the resulting restriction on sales of American dairy in Canada relative to other trading partners.
United States Trade Representative Jamieson Greer has framed the Canadian measures as retaliation and has argued that Canada and China are the only two countries to have formally retaliated against the current administration’s tariff program. Canadian officials reject the framing, maintaining that the provincial and federal countermeasures were themselves responses to American tariffs imposed first.
The dairy allegation has drawn particular scrutiny from trade economists. CSIS noted that researchers have repeatedly found United States dairy exports to Canada running well below the thresholds at which the higher over quota rates would apply, which complicates the claim that Canadian tariff rates are the operative barrier.
Legal exposure is another open question. No court has yet interpreted Section 338. The statute assigns the United States International Trade Commission a role in monitoring unfair treatment of American goods and reporting findings to the president, and the proclamations do not indicate whether that process was followed. Some trade lawyers have argued that Section 338 was implicitly repealed by later legislation. CSIS also observed that the duties would likely violate American commitments at the World Trade Organization, though it noted that Canadian WTO cases filed over the 2025 actions on steel, automobiles and certain agricultural products have not materially changed United States policy.
Carney’s Evidence: American Aluminum Prices
The most substantive economic argument Carney advanced on Thursday was not about Canadian losses. It was about American costs.
The Prime Minister said existing United States tariffs on aluminum have contributed to a 58 per cent increase in aluminum prices in the United States. “That’s not a good situation for American companies,” he said.
The claim is a deliberate reframing of the tariff debate. Tariffs are taxes collected at the importing border, and the empirical literature on the 2018 and 2019 metals actions found that American importers largely absorbed the duty through higher duty inclusive prices rather than Canadian exporters cutting their invoice prices to compensate. Statistics Canada research covering that earlier episode reached the same conclusion.
For Carney, the political utility of the aluminum price figure is that it addresses an American audience rather than a Canadian one. With United States midterm elections scheduled for November 3 and consumer frustration over living costs already elevated, the argument that Canadian metal tariffs are being paid by American beverage can makers, automotive suppliers and builders is aimed at constituencies inside the United States that have leverage on Capitol Hill.
Whether it lands is a separate question. The administration’s stated theory is that tariff costs will induce manufacturing to relocate to the United States. The Associated Press noted that there is little evidence of that relocation in the economic data to date.
Negotiators In The Room
Behind the rhetoric, the machinery of negotiation has accelerated sharply.
Canada United States Trade Minister Dominic LeBlanc, chief negotiator Janice Charette and Ambassador Mark Wiseman have made repeated trips to Washington through late July and early August. LeBlanc described a Thursday meeting with Greer as “constructive and detailed,” according to reporting compiled from The Globe and Mail, CBC News and CTV News. He departed Washington on Friday and is expected to return Monday. Both delegations have agreed to daily meetings at various levels through the deadline.
Industry sources with knowledge of the talks have described the atmosphere as tense and vulnerable to disruption at any moment by presidential intervention, a risk that Thursday’s Las Vegas remarks illustrated.
Canadian negotiators have reportedly argued to their American counterparts that August 19 represents a “cliff-type moment,” on the theory that there would be no political appetite in Canada to continue talks once the duties actually take effect. That argument is a bet that the threat of Canadian withdrawal from the table carries more weight in Washington than the threat of Canadian retaliation.
Carney has characterized the objective as a “comprehensive deal, a global deal” covering all strategic sectors, autos included. One source told CTV News that Canada is seeking what amounts to favoured nation treatment across sectors, meaning not the elimination of tariffs but access to the lowest applicable rate in each product category. That is a materially different ask than a return to the pre 2025 status quo, and it reflects an assessment inside the Canadian government that full restoration of duty free continental trade is no longer a realistic near term outcome.
The Domestic Politics
The Prime Minister’s willingness to describe the situation as a tariff war carries domestic risk, and the opposition has moved to exploit it from the opposite direction.
Conservative Leader Pierre Poilievre, speaking at a news conference in St. John’s, criticized the government for putting concessions forward in advance of a formal agreement. “I don’t understand the strategy of making concessions before even getting to the negotiating table,” Poilievre told reporters, arguing that Carney “isn’t holding out for a better deal.”
Carney rejected the criticism directly. “Whatever adjective is used, we’re standing up for Canadian workers, for Canadian businesses,” he said.
The exchange captures a genuine strategic disagreement rather than pure partisan positioning. The government’s approach assumes that removing the three named irritants gives Washington a face saving basis to suspend the Section 338 action, and that suspension is worth more than the negotiating leverage the irritants provide. The opposition’s approach assumes the opposite, that concessions offered without reciprocity simply reset the baseline for the next demand.
Recent history offers support for both readings. Ontario Premier Doug Ford suspended a retaliatory electricity surcharge on Michigan, New York and Minnesota after United States Commerce Secretary Howard Lutnick offered trade talks in exchange, and the American side escalated tariffs regardless. That episode has become the central cautionary tale cited by Canadian officials who favour holding leverage.
The Economic Backdrop
The tariff confrontation is unfolding against Canadian macroeconomic data that has been, on its face, resilient.
Statistics Canada reported on August 4 that merchandise exports rose 0.4 per cent in June to a record $77.5 billion, a fifth consecutive monthly increase, with exports up 22.8 per cent across that five month run. Imports edged up 0.2 per cent to a record $73.6 billion. The merchandise trade surplus with the world widened from $3.7 billion in May to $3.9 billion in June, a fourth consecutive surplus.
The composition of those numbers, however, is less reassuring than the headline. The June export gain was driven substantially by a 16.5 per cent increase in metal and non metallic mineral products, itself dominated by a 27.9 per cent rise in unwrought gold, silver and platinum group metals, largely reflecting shipments of gold to the United Kingdom and purchases of Canadian held gold by foreign residents. Exports of unwrought aluminum and aluminum alloys fell 28.8 per cent in the month. Energy product exports fell 10.0 per cent, driven by lower crude oil prices.
Statistics Canada also noted that the Canadian dollar’s average value fell 1.7 cents against the American dollar in June, the largest monthly decline since October 2022. Expressed in United States dollars, Canadian exports were down 2.0 per cent in June and imports down 2.1 per cent. Much of the apparent Canadian dollar strength in the trade figures is a currency translation effect.
On the United States relationship specifically, exports to the American market rose 0.3 per cent in June, a fifth consecutive increase, but imports from the United States rose 3.0 per cent to a record, and Canada’s bilateral surplus narrowed from $11.1 billion in May to $10.0 billion in June.
The agency’s own commentary flagged the divergence between the two most recent American tariff actions. Section 301 tariffs imposed on July 24 maintain a CUSMA exemption for Canadian imports and are therefore expected to have limited direct effect. The Section 338 measures scheduled for August 19 carry no such exemption.
The labour market picture released the following Friday added another layer. Statistics Canada’s Labour Force Survey for July, published August 7, showed employment up 75,000 on the month, a 0.4 per cent gain that came in roughly five times above the consensus expectation of about 15,000. The unemployment rate fell to 6.4 per cent, the lowest reading in two years and well below the 7.1 per cent peak recorded in August and September 2025. Gains were led by wholesale and retail trade, finance and insurance and real estate, professional and scientific services, and construction. Public administration and agriculture declined. Wage growth moderated to 2.8 per cent year over year from 3.3 per cent in June.
None of those gains came from the sectors most exposed to the August 19 action. That is the fragility beneath the headline: a labour market whose recent strength is concentrated in domestically oriented services while the tradeable goods sectors absorb the tariff shock.
What Importers And Exporters Should Be Doing
For businesses on either side of the border, the twelve days remaining before August 19 are operational, not rhetorical.
The first task is classification exposure. Because the three annexes are organized by eight digit Harmonized Tariff Schedule classification rather than by industry, a company cannot rule out exposure by reasoning from its sector. Every classification shipped into the United States should be checked against all three lists, including classifications that a business considers peripheral to its main product line.
The second is duty stacking arithmetic. Where a good is already subject to Section 232 duties on steel, aluminum or derivative content, the Section 338 duty applies in addition. Landed cost models built on the 50 per cent headline figure will understate the actual border liability, in some cases substantially. CSIS noted that Section 338 duties do not apply to goods already subject to Section 232 duties, a carve out whose scope importers should confirm classification by classification with counsel rather than assume.
The third is contractual allocation. Incoterms determine which party bears the duty, and standard delivered duty paid terms will place the full incremental cost on the Canadian seller. Contracts written before July 20 will not have anticipated a Section 338 exposure, and force majeure and change in law clauses in existing supply agreements should be reviewed now rather than after the fact.
The fourth is timing. Duties attach on entry, not on order date. Goods that clear United States customs before 12:01 a.m. Eastern on August 19 enter under existing rates. That creates a clear incentive to accelerate shipments in the coming days, with the corresponding risks of port congestion, carrier capacity constraints and inventory carrying cost that any pull forward entails.
The fifth is contingency for what follows. Sources have indicated that if the tariffs take effect, Canada is preparing what it describes as surgically targeted responses that are explicitly not counter tariffs, focusing instead on measures affecting American preferential access to procurement projects, critical minerals and energy. Ottawa has declined to specify those options while negotiations continue. American firms with Canadian procurement exposure, critical minerals offtake agreements or energy supply arrangements should treat that category as live risk.
The Weekend Question
The negotiating file now turns on a narrow question. Ottawa has assembled an offer keyed to the three named grievances. Washington has to decide whether that offer, as structured, justifies suspending an action the president has publicly tied to his broader posture toward a trading partner he described this week as nasty.
Greer has characterized the three targeted issues as procedurally straightforward to resolve, noting that two of them involve Canadian retaliatory measures that Ottawa could simply reverse. That framing understates the constitutional complexity on the Canadian side, where the alcohol component sits with provincial governments rather than the federal one.
Industry sources have told CTV News they are cautiously optimistic about progress toward a comprehensive bilateral agreement negotiated outside the formal trilateral CUSMA review framework, while cautioning against expecting a finished deal by August 19. The more probable outcomes are a partial or interim arrangement that suspends the Section 338 duties while broader talks continue into the fall, or a deadline that passes without agreement and triggers the duties along with the Canadian response.
Carney’s language this week suggests a government preparing its public for the second outcome while working toward the first. Describing the situation as a tariff war, rather than a negotiation, lowers expectations for August 19 and pre positions the political ground for whatever follows.
For the businesses that will pay the duties, the distinction between a tariff war and a tough negotiation is academic. The invoice arrives either way.
