Canada hits back with tariffs on $20bn of US goods as Trump trade war escalates

Canada has retaliated against the United States with tariffs on roughly $20 billion of American goods, including steel, dairy, appliances, farm equipment, seafood, cheese, clothing, cosmetics and toilet paper, as a trade dispute between the long-time partners turns hostile. The countermeasures, announced on Tuesday, come after the Trump administration imposed 50 percent duties on Canadian goods over the weekend following the collapse of bilateral trade talks.

The new Canadian tariffs will take effect on 8 September at rates of 15, 25 and 50 percent, matching the corresponding US rate on more than 700 products such as pulp, paper and electronics. The largest share of the measures falls on steel and aluminium, with some products doubling from 25 to 50 percent. François-Philippe Champagne, Canada’s finance minister, said the country did not choose the fight but had to respond.

"We did not choose this conflict, but when our economic integration is used as a weapon rather than the foundation for a win-win partnership, we need to stand up," Champagne said in French, calling the situation "an unprecedented challenge imposed on Canada".

From trade talks to threats

The weekend breakdown in negotiations prompted President Donald Trump to raise US duties on Canadian goods to 50 percent. On Monday he warned Canadian leaders to "fall in line" or face consequences "far WORSE" than existing tariffs, and threatened further 50 percent duties on Canadian vehicles, auto parts and steel.

Mark Carney, the Canadian prime minister, accused Washington of trying to subordinate Canada and said US demands during the failed talks showed Americans wanted to "destroy our major industries". He suggested Canada may move away from matching US tariffs dollar for dollar and instead adopt more targeted retaliation to protect workers and businesses.

"An attitude at the negotiation table that Canada is a subsidiary of the United States is not something we’re going to accept," Carney said.

Carney was even blunter in French. "We learned during the negotiations that the Americans want to destroy our major industries, including autos, steel and aluminium," he said. "That was one of the main reasons we said no. It was a bad deal."

He also disclosed that US negotiators had raised the discoverability of French-language content on streaming platforms and French-language labelling rules as trade irritants. He rejected any compromise on those protections, saying in French: "For the Americans, questions about the French language, Quebec culture, francophone culture and Canadian culture are irritants. Here in Quebec, here in Canada, they are rights."

Trump responded in a social media post early on Tuesday. "I would never interfere with Canadians speaking French! In fact, I have never even thought of doing such a stupid thing. This lie was made up by a weak and ineffective Prime Minister in an attempt to gain political support, which he has totally lost, from the people of Quebec. I love French Canadians!"

What Canada is targeting

Canadian officials said the goal is not to raise revenue but to shield domestic companies and reduce imports from the US. They pointed out that US steel imports have already fallen 30 percent since Canada imposed a 25 percent tariff, and the new 50 percent rate is expected to cut them further.

Goods facing 50 percent duties include some steel and aluminium products, furniture and clothing. Appliances, dairy products including cheese, fish and seafood, and certain steel and aluminium derivatives will face 25 percent tariffs. Existing Canadian countertariffs on US vehicles remain in place.

The government also unveiled a C$7.5 billion ($5.4 billion) support package for workers and businesses caught in the crossfire. Mélanie Joly, Canada’s industry minister, said it includes C$3 million ($2.1 million) of grants for small businesses through state institutions and C$2 million ($1.4 million) of interest-free loans. She acknowledged that business leaders and workers are anxious, but said the aim is to protect Canadians and their jobs.

Officials admitted the counter-tariffs will raise costs for some businesses and consumers, though they expect the overall economic impact to be moderate. They said Ottawa has provided more than C$30 billion ($21.7 billion) in tariff-related support since the start of 2025, far more than it has collected in retaliatory duties.

Impact on businesses and consumers

The US and Canada have deeply integrated supply chains across autos, energy, agriculture and manufacturing, so a prolonged trade fight risks hurting companies and workers on both sides of the border. Businesses and consumers are already facing uncertainty over how much prices may rise.

Michael Howard II, who owns a furniture business in Warren, Michigan, outside Detroit, said the tariffs would hamper his "ability for us to put food on the table for our family" and affect "the ability for us to give back to our community". Howard and his wife started the company a decade ago and make dining room tables, bookcases and other furniture.

"To say that we don’t need Canada is just disingenuous," he said. "It’s dishonest. And it’s just absolutely not truthful. We need our neighbour, but also they need us."

Trump added another provocation on Tuesday by saying the United States was giving "serious consideration" to renaming Lake Ontario "Lake America", reviving a feud with Ontario premier Doug Ford. The move would echo the Republican president’s unilateral executive order last year to rename the Gulf of Mexico the Gulf of America.

With neither side showing signs of backing down before the 8 September deadline, the dispute looks set to keep pushing up costs for manufacturers, retailers and households across North America.
