A last‑minute breakdown in talks between Ottawa and Washington has set off a fresh round of punitive duties, with President Donald Trump imposing 50 % tariffs on roughly US $28 billion of Canadian exports, and Prime Minister Mark Carney pledging a “dollar‑for‑dollar” response. The failure of the tentative agreement, which fell apart less than an hour before a Friday deadline, leaves both sides bracing for an abrupt escalation in the North American trade dispute.

Trade talks collapse amid accusations
The negotiations, which have been on‑and‑off for more than a year, were intended to secure relief from a suite of American levies: 50 % on steel and aluminium, 25 % on automobiles, and tariffs ranging from 10 % to 25 % on forestry products, among other sector‑specific duties. A deal had been reached earlier in the week, prompting Trump to suspend the new duties until 12.01 am on Saturday while the two sides finalised the details.
According to Carney, the United States attempted to alter the terms at the eleventh hour, prompting him to pull Canadian negotiators from the table. “Last‑minute changes in the U.S. proposed terms were unfair, uneconomic and called into question the reliability of any deal,” Carney said in a statement. He added that Canada would “match those tariffs dollar for dollar to protect our workers and businesses.”
U.S. Trade Representative Jamieson Greer, speaking to reporters late on Friday, placed the blame on Canada, claiming that Ottawa had demanded further concessions after the U.S. had already offered the most favourable treatment of any major exporter. “New demands and walk backs of other commitments by Canada have upended the careful balance reached in the past days,” Greer said. The proposed agreement was also expected to cover national security, critical minerals and aerospace coordination.
If Ottawa follows through on its threat, a senior U.S. official said Trump will have options to counter‑strike. The official’s identity was withheld by The Globe and Mail as a condition of the briefing.
The Canadian side was led by Trade Minister Dominic LeBlanc and chief negotiator Janice Charette, with PM’s chief of staff Marc‑André Blanchard and Ambassador Mark Wiseman also present for the second consecutive day at Greer’s office near the White House.

Tariff specifics and economic fallout
The new levies will affect about 5 % of Canada’s total exports to the United States, translating into a modest but sector‑specific shock. Royal Bank of Canada economists estimate the impact of the new Section 338 tariffs at 0.4 % of GDP, while Capital Economics puts the figure at 0.6 %. The tariffs are expected to hit manufacturing industries such as electronics, plastics, paper products, furniture and home appliances particularly hard.
RBC suggests that up to 20 % of production and jobs in the electronics and apparel sectors could be jeopardised. Regional disparities are pronounced: Ontario, Quebec and British Columbia face the brunt, whereas Alberta and Saskatchewan remain largely untouched.
Candace Laing, CEO of the Canadian Chamber of Commerce, warned that the measures would “be a body blow to North American competitiveness in this self‑defeating trade saga. A whopping, non‑absorbable tariff is not sustainable or viable for business.” She noted that both American consumers and Canadian businesses would suffer, with higher costs and lost investment.
Ontario Premier Doug Ford, who had remained silent throughout the week, endorsed Carney’s retaliatory plan. “Team Canada needs to stand together more united than ever before,” Ford posted on social media. “The prime minister has my full support for a strong response – tariff for tariff, dollar for dollar.”
Ford’s earlier anti‑tariff advertisement in October had contributed to the termination of previous negotiations, underscoring the delicate balance Carney must strike with provincial leaders. The premiers were asked to end their own retaliatory bans on American alcohol and “Buy Canadian” procurement practices, even though the proposed federal deal would impose heavy costs on some of their provinces.

Political fallout and provincial tensions
Carney entered office promising an “elbows up” stance against Trump’s tariffs and annexation threats. Since then, his government has oscillated between a hard line and pragmatic concessions. Unlike the United Kingdom, the European Union, Japan and other nations that accepted punitive U.S. terms last year, Carney held out for a more favourable arrangement.
To sweeten the deal, Ottawa made several unilateral concessions without receiving reciprocal benefits. Last year, Canada scrapped its planned digital services tax, increased military spending and border security, and rolled back its own retaliatory tariffs. This year, the government reversed requirements that streaming services like Netflix and Amazon invest in Canadian content and agreed to share revenue from the Gordie Howe International Bridge with the United States, despite having funded the entire project.
These moves have drawn criticism from provincial and industry officials who claim they were kept in the dark about the specifics of the federal negotiations. Ottawa released no public details on the talks, fuelling accusations of opacity.
U.S. officials, meanwhile, have repeatedly complained about Ottawa’s perceived intransigence. They point out that Canada and China were the only two foreign governments to actively resist Trump’s global trade offensive, and they highlight Carney’s vocal rebuke of American hegemony at the World Economic Forum in Davos earlier this year.

Strategic dimensions and future prospects
Beyond the immediate tariff dispute, the negotiations touched on a broader set of security and economic issues. U.S. negotiators raised concerns about Canada’s delayed F‑35 fighter‑jet purchase, the development of critical minerals, the Golden Dome missile‑defence system and oil exports. Commerce Secretary Howard Lutnick, who became directly involved in the talks earlier this week, reportedly pushed for a tougher stance, seeking more extensive concessions from Ottawa.
The steel component of the proposed deal was especially onerous. Canada would have been required to accept a four‑million‑tonne export quota to the United States, with a 25 % tariff on steel within that quota and a 50 % levy above it. In exchange, Ottawa would have had to eliminate all its counter‑tariffs on U.S. steel.
On forestry, the U.S. side indicated it did not want the sector included in any agreement, while Canada insisted that it be part of the package. In the automotive sector, the U.S. offered to exempt only American‑made content from tariffs, whereas Canada sought exemptions for Canadian and Mexican content as well.
The breakdown of the talks leaves both governments to assess the costs and benefits of continued escalation. For Canada, the immediate economic pain is limited but concentrated, raising questions about how Ottawa will balance domestic industry protection with its broader diplomatic posture. For the United States, the tariffs are a tool to pressure Canadian negotiators, but risk inflating costs for American consumers and disrupting integrated supply chains.

Why it Matters
The collapse of the Canada‑U.S. trade deal marks a pivotal moment in North American economic relations, signalling a return to the high‑stakes tariff warfare that has defined the Trump administration’s approach to its neighbours. While the direct fiscal impact on Canada’s GDP is modest, the sector‑specific damage threatens jobs in key manufacturing hubs and could reverberate through interconnected supply chains that span the continent. Moreover, the dispute underscores the fragility of diplomatic compromise when domestic political pressures on both sides demand a hardline stance. The escalation also raises broader concerns about the future of continental trade integration, especially as other nations watch whether Ottawa’s “dollar‑for‑dollar” retaliation will set a precedent for resisting U.S. economic pressure. In a region where seamless commerce underpins economic strength, today’s tariff battle could reshape the competitive landscape for years to come.
