Canadian businesses brace for fallout as U.S. 50-percent tariffs take effect after trade talks collapse

U.S. President Donald Trump’s 50-per-cent tariffs on $20-billion USD worth of Canadian goods took effect Saturday after trade talks between Ottawa and Washington collapsed, prompting business groups, unions and industry leaders to warn of job losses, plant closures and higher prices. Prime Minister Mark Carney has vowed dollar-for-dollar retaliation against American exports starting Sept. 8—but critics caution that counter-tariffs could drive up costs for Canadian farmers and consumers, compounding the damage of a prolonged trade war. The duties, which took effect at 12:01 a.m. Saturday, fall primarily on Canada’s manufacturing sector and cover goods ranging from steel and aluminum products to gold, silver and imitation jewelry. Both governments blamed each other for the breakdown, which came just as an agreement had appeared within reach, and the collapse extinguished hopes for an end to the uncertainty that has stalled Canadian investment decisions for over a year. Carney said he called off negotiations Friday night because Washington’s terms were unacceptable, arguing the cumulative weight of American demands had exposed the limits of the U.S. commitment to a genuine economic partnership. Asked about the martial tone of his remarks, referring to the tariffs as an act of war, the prime minister told reporters at a press conference: “You are at war when you get attacked. We got attacked.” Ottawa’s counter-tariffs, set to begin Sept. 8, will target American steel, dairy, appliances, agricultural equipment, pulp and paper and electronics. Alberta Premier Danielle Smith cautioned that the retaliatory measures could force Canadian farmers to pay 50 percent more for the machinery they need to produce food—the very risk critics have flagged in matching Washington’s levies. Trump, meanwhile, claimed on his Truth Social platform that Canada wants the advantages of American statehood without joining the union, and accused Ottawa of charging U.S. farmers heavy tariffs. Much of Canada’s business community nonetheless backed the decision to walk away. Dennis Darby, chief executive of Canadian Manufacturers and Exporters and a member of Carney’s advisory committee on Canada-U.S. economic relations, said the prime minister’s language suggested he is preparing for a lengthy standoff, though the group would prefer a quick return to the table. The Canadian Steel Producers Association argued that no deal is preferable to a bad one, pointing to more than three decades of integrated cross-border trade. Brampton, Ont., Mayor Patrick Brown, whose city has seen more than 3,000 workers idled by the shutdown of the Stellantis Assembly Plant, said he was glad Canadian negotiators refused terms that would have left the auto sector exposed. Small businesses are already counting the cost. Calgary jewelry maker Cindy Baldassi, whose online shop sells sterling silver, stone and dinosaur fossil pieces, told the Canadian Press she expects to lose roughly half her customers because 75 percent of her buyers are American. “We should fight back,” Baldassi said, while acknowledging that retaliation will be hard on many Canadians. The confrontation sharpens long-standing questions about Ottawa’s strategy of reducing dependence on the American market. Graeme Gordon, The Hub‘s senior correspondent, has reported that Carney logged 26 foreign trips in his first year in office and pledged to double non-American exports within a decade, yet the plan faces a structural problem. “But experts and business leaders say the strategy contains a fundamental paradox: Canada’s ability to attract foreign investment and strike new trade deals depends heavily on the very relationship with the U.S. it is trying to reduce reliance upon,” Gordon wrote, noting that preferential access to the American market remains the chief draw for prospective trading partners. Recent trade data underline how far diversification has actually progressed. “Goods exports to the U.S. fell 5.8 percent in 2025, nearly offset by a 17.2 percent jump elsewhere—though much of that gain reflects record gold shipments rather than diversification, and the U.S. share of Canadian exports fell to 71.7 percent, its lowest since the early 1980s,” Gordon noted. The economic backdrop is already strained. The Bank of Canada projects GDP will end 2026 roughly 1.5 percent below its pre-tariff trajectory, and Deloitte’s summer outlook forecast growth of just 0.7 per cent this year, blaming trade uncertainty. With no date set for talks to resume, Canada’s counter-tariffs are scheduled to take effect Sept. 8. U.S. President Donald Trump’s 50% tariffs on $20 billion worth of Canadian goods have taken effect following the collapse of trade talks between Canada and the U.S. Prime Minister Mark Carney announced retaliatory tariffs against American exports, set to begin on September 8. The tariffs primarily target Canada’s manufacturing sector, raising concerns about job losses and increased costs for consumers. Business leaders express support for Carney’s decision to walk away from negotiations, while small businesses anticipate significant impacts. The ongoing trade tensions highlight Canada’s struggle to diversify its economy away from dependence on the U.S. market.
