Canada's counter-tariffs took effect at 12:01 a.m. on September 8, hitting nearly C$28 billion (about $20 billion) of American goods with duties from 15% to 50%. Milk, perfume, golf clubs, steel, aluminum, and T-shirts face 50% tariffs; cheese, carpets, and household appliances face 25%; forklifts face 15%.
The move matches the 50% tariffs the U.S. placed on Canadian goods on August 22 after trade talks collapsed. Trump responded by threatening to ban Bombardier jets from the U.S. market; Bombardier says it supports tens of thousands of American jobs. Eight of Canada's 10 provinces restrict or ban U.S. alcohol sales, and American spirits exports to Canada have fallen more than 70% year over year.

"Tariffs are a tax on your own people dressed up as patriotism. These men are strangling the very commerce that made their fortunes possible—steel, rails, and transport built this continent as one market, not twenty fractured fiefdoms nursing wounded pride."

"I warned them in '32 that Smoot-Hawley would strangle commerce, yet here we are repeating the same folly with different flags. The mathematics of reciprocal destruction remain unchanged: when neighbors tax each other into poverty, neither collects revenue worth having."

All three countries agree to renew the USMCA for another 16 years, but only after Canada and Mexico accept new terms. Possible concessions include stricter rules of origin for automobiles, concessions on dairy and lumber market access, alignment with U.S. trade restrictions on China, and formal side letters institutionalizing some tariff levels. Steel and aluminum tariffs may remain in place even as the broader agreement continues.

The three countries fail to agree on renewal but none withdraws. Under USMCA Article 34.7, this triggers annual reviews where the agreement remains in force but its future stays uncertain. This creates persistent policy uncertainty, discouraging long-term investment in cross-border manufacturing while existing supply chains continue functioning. Tariffs on non-compliant goods remain.
Discussed by: U.S. Trade Representative Greer has floated bilateral frameworks; AmCham Mexico considers this suboptimal but possible
The U.S. withdraws from USMCA and negotiates separate bilateral agreements with Canada and Mexico. This would eliminate the integrated North American supply chain framework and create different rules for each border. Critics warn this would be 'highly complex' and economically damaging, but it would give the U.S. more leverage in separate negotiations.
Discussed by: Prime Minister Carney's Davos remarks; trade diversification strategy announcements
Unable to secure tariff-free access to the U.S. market, Canada accelerates trade deals with the European Union, Asia-Pacific nations, and others. Carney has already announced plans for 12 new trade agreements. The U.S.-Canada relationship stabilizes at a higher-tariff equilibrium, with Canadian manufacturers shifting focus away from American customers. The USMCA continues but with diminished practical importance.

Trump has promised to raise tariffs on Canadian vehicles, auto parts and steel from 25% to 50% starting January 1, 2027, unless Canada 'falls in line.' Auto industry analysts warn the increase would hit deeply integrated North American supply chains, where parts cross the border multiple times during assembly.

Trump said he would block Bombardier jets unless they are built in the U.S. A ban would hurt Bombardier, since more than half of its 2025 revenue came from the U.S. The company employs 3,500 people in the U.S., which could make a ban politically awkward.
3 moments from history that rhyme with this story — and how they unfolded.
Despite warnings from over 1,000 economists and opposition from executives like Henry Ford and J.P. Morgan's Thomas Lamont, President Hoover signed the Smoot-Hawley Tariff, raising average tariffs on dutiable imports from 40% to 47%. As the Depression caused deflation, the effective rate reached nearly 60% by 1932. Canada responded by imposing tariffs covering 30% of U.S. exports within months.
Over two dozen countries enacted retaliatory tariffs. U.S. imports fell 66% from $4.4 billion to $1.5 billion between 1929 and 1933.
Smoot-Hawley became synonymous with protectionist overreach, leading to the 1934 Reciprocal Trade Agreements Act and decades of bipartisan consensus against high tariffs. Senators Smoot and Hawley both lost their seats in 1932.
Today's 16.9% effective U.S. tariff rate is the highest since 1932, the peak of Smoot-Hawley's impact. Canada was the first country to retaliate against Smoot-Hawley, just as it has responded dollar-for-dollar to current U.S. tariffs.
In response to U.S. protectionism and the Depression, Britain and its dominions including Canada met in Ottawa to create a system of preferential tariffs within the British Empire. Britain abandoned its longstanding free trade policy, and Canada strengthened ties with British markets while reducing dependence on American trade.
Britain's imports from the Empire increased from under 30% to over 40%. Trade patterns shifted dramatically away from the United States.
Imperial Preference lasted until the 1970s and demonstrated how protectionism can accelerate the formation of competing trade blocs rather than simply reducing overall trade.
Carney's announcement of 12 new trade deals at Davos echoes Canada's 1932 pivot toward alternative trading partners. Then as now, U.S. tariffs prompted Canada to seek closer ties elsewhere.
In his first term, Trump imposed 25% tariffs on steel and 10% on aluminum under Section 232, citing national security. After initial protests, Canada and Mexico were granted exemptions as part of USMCA negotiations. The EU, Japan, and other allies negotiated quota arrangements.
The U.S. steel industry added nearly 5,000 jobs, but downstream manufacturers faced higher input costs. Analysts calculated $270,000 in added industry profits per steel job saved.
The tariffs remained in place through the Biden administration. They established the precedent for using Section 232 authority broadly, paving the way for the current expansion.
The 2025 tariff escalation explicitly revokes the exemptions negotiated in 2018. Canada went from exempted ally to facing 50% steel tariffs in seven years, demonstrating how bilateral trade arrangements can unravel.
