Canada’s retaliatory tariffs on roughly C$27.6 billion worth of American goods came into force at 12:01 a.m. on 8 September 2026, according to a briefing by Husch Blackwell’s International Trade & Supply Chain Insights, with no trade talks scheduled and no deal in prospect.
The counter-tariffs, set at rates of 15%, 25%, or 50%, cover hundreds of American products: milk, golf clubs, steel, aluminium, jackets and T-shirts face the top rate of 50%; cheese, toilet paper, and certain household appliances face 25%; forklift trucks and industrial moulds come in at 15%.
Prime Minister Mark Carney has described the levies as ‘dollar-for-dollar’ retaliation. Taken together, Cox & Palmer notes the affected trade represents roughly 5% of Canada’s annual goods exports to the United States, which puts the scale of the counter-strike in perspective: significant enough to sting, not large enough to force a quick resolution.
What Canada’s Retaliatory Tariffs Actually Cover
The tariff list is broad but not indiscriminate. Fresh fish and lobster were originally included, then pulled after the seafood industry objected. The lobster trade illustrates why self-harm is a constant risk here: American-caught lobster is routinely shipped north to be processed in Canada before being sold back to the US. A 50% tariff on it would have punished Canadian processors as much as American fishermen.
The Canadian government‘s list also excludes goods covered by existing retaliatory taxes on American cars and trucks that fall outside the Canada-United States-Mexico Agreement (known as CUSMA in Canada, USMCA in the US). Those pre-existing levies remain in place alongside Tuesday’s new round.
On the American side, the tariff burden on Canada is already steep. The US applies a 25% tax on Canadian cars and trucks. Canadian steel and aluminium face a 50% US tariff rate, a point clarified by Cox & Palmer’s analysis, which is distinct from the headline car rate that tends to dominate coverage.
The Bombardier Threat and What It Would Actually Cost Canada
President Donald Trump’s threat to cut off US business with Bombardier unless the aerospace company moves its manufacturing south is the most pointed act of economic coercion so far. The numbers behind that threat are worth sitting with.
According to a PwC Canada report commissioned by Bombardier, the company contributed C$7.4 billion to Canada’s GDP in 2024, counting direct, indirect, and induced impacts. Of that, C$6.1 billion was attributable to Quebec alone. The company supported close to 50,000 jobs across Canada, including nearly 10,000 direct positions in Quebec, representing more than 31% of all aerospace sector jobs in Quebec’s manufacturing industry. Bombardier’s activities also generated over C$1.2 billion in provincial and federal government revenues in 2024, from taxes on income, products, and production.
Looking further out, PwC projects Bombardier will contribute C$39.6 billion to Canada’s GDP between 2025 and 2029, sustaining an annual average of over 51,500 direct, indirect, and induced full-time jobs. Bombardier’s output in 2024 already represented approximately 1% of total Canadian exports; its aircraft exports made up 5% of Quebec’s total export value that year.
Trump’s threat, in other words, is not a shot across the bow at a modest niche manufacturer. It is aimed squarely at the industrial backbone of one of Canada’s most politically important provinces.
An Economy Under Strain, But Not Yet Buckling
Canada’s economy had been holding up better than many expected before this latest escalation. GDP grew 3.3% in the second quarter of 2026, and the country added 181,000 jobs between April and July. Then August arrived: 41,000 jobs were lost in a single month, a period that coincided directly with new US tariffs and the collapse of trade talks.
Canada’s retaliatory tariffs may shore up domestic political support, but economists warn they will raise prices for ordinary Canadians on clothing, food, and furniture. The Canadian Chamber of Commerce has urged a ‘surgical’ approach. ‘Businesses understand retaliation but don’t want to see endless escalation,’ said Candace Laing, the Chamber’s CEO and President, though she added that businesses ‘are preparing for this trade dispute to last.’
Carney says he wants to reduce Canada’s dependence on the US market. July figures suggest some early movement: the share of Canadian exports heading to the US fell to 66%, down from an average of 75% before the trade war began. Redirecting a trading relationship valued at nearly $900 billion in 2025, however, is not a project that can be completed before the next round of tariffs lands.
US Trade Representative Jamieson Greer said last week the ball is in Canada’s court. ‘We offered them the best deal, they looked at it square in the face and turned around,’ Greer told Fox News. With World Trade Organization dispute mechanisms too slow to matter in real time, the question is simply which side blinks first. Given Carney’s domestic political position and Trump’s wider territorial posturing, neither appears close to blinking.
