Ottawa will match Washington’s new duties dollar for dollar from September 8, targeting American steel, dairy, appliances, farm equipment, pulp and paper and electronics. Canadian importers have roughly two weeks to prepare.
OTTAWA, August 23, 2026 – Prime Minister Mark Carney has given Canadian industry a date and a target list. Beginning September 8, the Tuesday after Labour Day, Canada will impose retaliatory tariffs on imports of American steel, dairy products, appliances, agricultural equipment, pulp and paper, and electronics, matching in value the 50 percent duties Washington began collecting on Canadian goods at 12:01 a.m. Saturday.
“Canada will match Washington’s new tariffs dollar for dollar in order to protect Canadian workers, farmers, families, and businesses,” Carney told reporters in Ottawa on Saturday, according to Al Jazeera’s account of the news conference. He described the response as focused rather than sweeping, and said the government would publish the detailed product list in the coming days.
The announcement came less than eighteen hours after Carney suspended negotiations with the United States and recalled his negotiating team from Washington, ending a process that had run for more than a year. On Saturday morning he wrote on social media that his negotiators had worked “in good faith” throughout, and that Ottawa would release the details of the new tariff measures, “which will come into force the Tuesday after Labour Day.”
For Canadian importers, customs brokers and manufacturers that rely on American inputs, the sixteen-day gap between announcement and implementation is the most actionable feature of the package. It is also the narrowest planning window Ottawa has offered in this dispute since the spring of 2025.
The shape of the countermeasures
Carney identified six sectors: steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics. He added that the list would also capture some products the United States has itself targeted, a reference to the reciprocal logic that has governed Canadian countermeasures throughout the dispute. NPR reported the same six categories from his Friday night statement and Saturday remarks.
The sectoral choices are not arbitrary. Each has a domestic Canadian industry capable of supplying at least part of the displaced volume, which limits the inflationary cost of the measure while maximising the political signal sent to American producers and the congressional delegations that represent them.
Steel is the most established front. Canada has maintained retaliatory tariffs on American steel and aluminium since March 2025, when it imposed 25 percent duties covering roughly 12.6 billion Canadian dollars of steel and 3 billion dollars of aluminium, according to the timeline maintained by Blake, Cassels and Graydon. Those measures survived the September 2025 rollback that removed Canadian counter-tariffs on consumer goods and the original Phase 1 list. Adding to them is administratively straightforward because the surtax machinery already exists.
Dairy is the most symbolically pointed. One of the three American proclamations that took effect Saturday rests on the allegation that Canada gives European cheese exporters better quota access under CETA than it gives American exporters under CUSMA. Retaliating against American dairy answers that charge in kind.
Appliances, agricultural equipment and electronics reach into manufacturing supply chains in the American Midwest and South. Pulp and paper touches the same forest products complex that has been at the centre of the softwood lumber dispute for four decades.
The dollar-for-dollar framing implies a countermeasure package valued at roughly the same level as the American action. Estimates of that action vary with the currency used and the trade year measured. White and Case calculated the three proclamations at approximately 20 billion U.S. dollars of 2024 and 2025 imports, or about 5 percent of total American goods imports from Canada. The Canadian Press reported the figure as 28 billion dollars. Al Jazeera put coverage at about 5.5 percent of Canadian exports to the United States. A Canadian package in the range of 25 to 30 billion Canadian dollars would be consistent with the Prime Minister’s language.
How the mechanism works
Canadian retaliatory tariffs are imposed by order in council under the Customs Tariff, typically as a United States Surtax Order, and are administered by the Canada Border Services Agency through customs notices that specify affected Harmonized System codes and the surtax rate. Precedent from 2025 suggests several features importers can reasonably expect.
The rate has generally been 25 percent rather than a mirror of the American percentage, with the dollar-for-dollar match achieved by adjusting the breadth of the product list instead. Carney’s language on Saturday referred to matching value, not matching rates, which points the same way. Importers should not assume a 50 percent Canadian surtax.
Surtaxes apply to goods originating in the United States, determined under the rules of origin in the Customs Tariff, not simply to goods shipped from the United States. That distinction matters for distribution businesses that source third-country product through American warehouses.
Orders have historically applied to goods accounted for on or after the effective date, which gives importers a genuine ability to accelerate shipments. Firms with September and October requirements for American steel, appliance components, electronics or paper stock have a real, if brief, arbitrage window.
Remission is the file to watch
The most consequential detail in past Canadian countermeasure packages has not been the tariff list but the remission framework attached to it.
The United States Surtax Remission Order made in April 2025 provided temporary relief from Canadian counter-tariffs for goods used in Canadian manufacturing, processing, and food and beverage packaging, and for goods serving public health, health care, public safety and national security objectives, according to the Blakes timeline. That relief was extended repeatedly through 2025 and into 2026. A separate order established a performance-based remission framework for automakers. Ottawa also stood up the Large Enterprise Tariff Loan Facility to provide liquidity to firms caught by the trade disruption.
The pattern of extensions has been intricate. By December 2025, remission for steel goods used in general manufacturing, processing, food and beverage packaging and agricultural production ran to January 31, 2026, while remission for steel used in motor vehicle, aerospace and parts manufacturing ran to June 30, 2026. Aluminium remission for manufacturing and packaging uses ran to June 30, 2026, as did relief for goods used in public health, health care, public safety and national security.
Separately, in June 2026, Finance Canada announced it would extend the steel tariff-rate quota regime and horizontal tariff relief on eligible steel and aluminium products from the United States for one further year, to June 27 and June 30, 2027 respectively, subject to Governor in Council approval.
The practical question for a Canadian manufacturer is therefore not only whether an input appears on the new surtax list, but whether an existing or forthcoming remission order covers the use to which that input is put. Firms should be assembling the documentation now: bills of material, end-use certifications, evidence that no domestic or non-American substitute is available at commercial volumes, and quantified cost impact. Remission applications supported by that record have fared considerably better than those that were not.
Support measures promised for next week
Carney said Saturday that Ottawa would announce support measures next week for industries hit by the American duties, and that those measures could remain in place for years. The Canadian Press reported the same commitment.
He did not specify instruments. The 2025 toolkit combined liquidity support through the Large Enterprise Tariff Loan Facility, remission relief, employment insurance work-sharing arrangements, and procurement preference through the Buy Canadian policy announced in November 2025, which directs federal purchasing toward Canadian materials including steel and lumber.
The reference to multi-year duration is the notable part. It signals that the government is no longer planning around a near-term settlement. That is a meaningful shift in posture from the spring, when relief measures were structured in six-month increments on the assumption that a negotiated outcome would arrive.
Reaction
Support for retaliation was broad, though rarely enthusiastic.
Ontario Premier Doug Ford, whose province carries the largest share of exposed manufacturing, endorsed the decision to walk away rather than sign. “I’m glad he didn’t sign that deal because it was a bad deal,” Ford said Saturday, as reported by Al Jazeera. “It was a bad deal for Ontario. It was a bad deal for the auto sector, the steel sector, and manufacturing sector.”
Unifor president Lana Payne said the negotiators made “the right decision by walking away,” telling The Canadian Press that “we can’t trade good jobs for a bad deal. And it was clear the U.S. was continuing to push for untenable concessions.” She described the American demands as “designed to break us and own us.”
Bea Bruske of the Canadian Labour Congress said the decision was right while acknowledging the cost. “The road ahead will be tough. But we’re all in this together,” she said. “We must use our leverage to force Trump to back down. And we must focus on protecting workers and communities impacted by Trump’s trade war.”
Diamond Isinger, a former special adviser to Prime Minister Justin Trudeau, told Al Jazeera that retaliation was the only viable course. “It’s going to cause pain and challenge for Canadians and Americans alike,” she said, “but ultimately this was the way forward; this was the only realistic next step.” She argued that the American administration responds best to strength, and that accepting 50 percent tariffs without response was not tenable.
Business groups were more equivocal, supporting the refusal to accept unfavourable terms while warning about the cost of escalation. Candace Laing of the Canadian Chamber of Commerce called the breakdown a “body blow to North American competitiveness,” and noted that “a whopping, non-absorbable tariff is not sustainable or viable for business.” Dan Kelly of the Canadian Federation of Independent Business reported that 40 percent of small exporters sell products on the American list, and that many members expect the duties to end their American sales.
Polling suggests the government has room to act. A Leger survey conducted the previous week found 56 percent of Canadians favoured a hard line with no further concessions, according to Al Jazeera.
Washington’s response was dismissive. Jamieson Greer, the United States Trade Representative, told Fox News on Saturday that no new talks are planned. “We’re moving forward with measures that respond to Canadian retaliation,” he said. President Trump wrote on social media that “Canada wants the benefits of being a State, without being one!!!”
The cost of retaliation
Counter-tariffs are a tax on Canadian buyers, and the September 8 package will raise input and consumer costs inside Canada. The design choices Ottawa has made are attempts to keep that cost manageable.
Steel is the clearest case of a deliberate trade-off. Canadian mills can supply a substantial share of domestic demand, but not all grades and not all specifications, and construction and fabrication buyers have felt the squeeze from the existing surtax regime and the tightened tariff-rate quotas introduced in December 2025, which cut quota levels to 20 percent of 2024 volumes for countries without a Canadian free trade agreement and 75 percent for non-CUSMA agreement partners, with over-quota volumes facing a 50 percent surtax.
Appliances and electronics are more difficult. Canadian domestic production is limited, and much of what enters from the United States is either American-made or third-country product that has passed through American distribution. Surtaxes on these categories will show up in retail prices with relatively little domestic substitution to offset them.
Agricultural equipment is a similar story. Canadian farmers buy a large share of their machinery from American manufacturers, and the June 2026 American proclamation that reduced Section 232 rates on agricultural machinery from 25 percent to 15 percent was itself a recognition of how tightly integrated that market is. A Canadian surtax raises capital costs for producers already dealing with narrow margins.
Dairy runs the other way. Canada’s supply management system already limits American access, so the incremental economic effect of a dairy surtax is small. That is precisely why it works as a political instrument.
The macroeconomic backdrop is unhelpful. The Bank of Canada projected growth of about 1.1 percent for 2026 with net exports weighing on the expansion. Statistics Canada reported that output in tariff-affected industries fell 4.0 percent across 2025, with aluminium down 15.5 percent and motor vehicle body and trailer manufacturing down 11.6 percent. Real Canadian exports have been running around 2 percent below 2024 levels. The unemployment rate eased to 6.8 percent in the fourth quarter after peaking near 7.0 percent.
Reporting from Calgary for Al Jazeera, correspondent David Mercer said the expectation is that “costs are going to go up, prices are going to go up, unemployment is going to go up as well,” with warnings that some small and medium-sized businesses will fail.
Canadians interviewed in southern Ontario reflected both strands of sentiment. Stuart Edwards, in Port Colborne, said the trade war would “hurt everybody” but that Canada would fight back. Pamela Coulis, in Fort Erie, worried about prices: “I think probably the gas will go up even more, and all products, from food to, I don’t know, wood, everything else.”
A checklist for the next two weeks
Canadian importers have a defined set of tasks before September 8.
Identify exposure at the tariff line. The six announced sectors are broad labels, and the operative document will be a customs notice listing specific Harmonized System codes. Firms should map their American purchases to those codes as soon as the list is published, and should not wait for the order to begin the mapping exercise against the announced categories.
Verify origin, not shipment point. Surtaxes attach to goods originating in the United States. Product manufactured elsewhere and warehoused in the United States may fall outside the order, and firms should confirm origin documentation before assuming either outcome.
Accelerate what can be accelerated. Orders accounted for before the effective date should escape the surtax, subject to the terms of the eventual order. Cash flow, warehouse capacity and shelf life set the practical limits.
Prepare remission applications. If an American input is used in Canadian manufacturing, processing, food and beverage packaging or agricultural production, or serves public health, health care, public safety or national security purposes, precedent suggests relief may be available. The documentation burden is real and the queue will be long.
Requalify suppliers. Where domestic, European, Mexican or Asian alternatives exist, the surtax changes the comparison. Qualification takes months, which argues for starting during the notice period rather than after.
Revisit contracts and pricing. Duty allocation clauses, delivered duty paid terms and fixed-price commitments written before this round need review. So do customer-facing price lists, since a surtax that lands on September 8 flows through to Canadian buyers within a quarter.
Track the support package. The measures Carney promised for next week may determine whether an exposed firm can bridge the disruption.
What comes next
The September 8 date creates a two-week interval in which the two governments could, in principle, resume contact. Nothing in the public record suggests they will. Greer has said no talks are scheduled and that Washington is preparing measures responding to Canadian retaliation, which raises the prospect of a further American round rather than a de-escalation.
Carney has framed the moment as an argument for diversification, and has spent much of the year pursuing trade and security relationships in Europe and Asia. The obstacle is arithmetic. Roughly 70 percent of Canadian exports go to the United States, and about 3.5 billion dollars in goods and services crossed the border each day in 2025 on the Expert Group on Canada-U.S. Relations’ estimate. Diversification is a decade-long project offered as an answer to a problem measured in weeks.
“Canada has what the world wants,” Carney said Friday night. “And we will not allow any nation to determine our future.” On September 8, that proposition acquires a price tag that Canadian importers will pay first.
The provincial dimension
Ottawa controls the surtax, but provinces control several of the levers that have most irritated Washington, and the September 8 package will not settle that question.
The alcoholic beverages proclamation that took effect Saturday rests entirely on provincial conduct. Beginning in March 2025, provincial liquor boards removed American wine, beer and spirits from their shelves in response to the initial American tariffs and to repeated presidential suggestions that Canada become a fifty-first state. Because those delistings were not applied to any other trading partner, the proclamation argues, they constituted discrimination within the meaning of Section 338. The White House cited an approximately 81 percent decline in American alcohol exports to Canada following the boycotts, alongside a rise of about 170 million dollars in exports from other countries into the same shelf space.
That creates an awkward federal-provincial dynamic. The measures giving rise to roughly 1 billion dollars of American tariff exposure were not federal decisions, and Ottawa cannot unilaterally reverse them. Nor is there political appetite to try. Provincial premiers have been among the loudest advocates of a harder line, and the liquor board delistings remain among the most visible expressions of Canadian consumer sentiment in the dispute.
The same holds for procurement. The Buy Canadian policy announced in November 2025 directs federal purchasing toward Canadian materials including steel and lumber, and several provinces have adopted parallel preferences. Those policies raise their own questions under CUSMA government procurement obligations and could plausibly become the basis for further American action under Section 338, which requires only a finding that Canada treats American commerce less favourably than that of other countries.
For exporters, the lesson is that the risk map now extends beyond federal tariff schedules. Provincial liquor policy, provincial procurement rules and provincial content requirements have all become inputs into American tariff decisions. Firms assessing exposure should be reading provincial announcements alongside federal ones.
