The retaliatory measures, described by Carney as 'dollar-for-dollar,' apply tariffs as high as 50% on a wide range of American imports. The list initially included fresh fish and lobster, but Canada removed those items after pushback from its seafood industry—underscoring the delicate balance the government must strike as it hits back at its largest trading partner.
The tariffs are layered atop existing Canadian retaliatory taxes on finished US cars and trucks that do not comply with the US-Mexico-Canada Agreement. They come in response to US tariffs imposed earlier this year, including a 25% tax on Canadian cars and trucks, taxes on steel, aluminum and lumber, and 50% tariffs on dairy, alcohol, hockey sticks and perfume announced by President Donald Trump in late August.
'We're ready to sit down and strike that deal when the Americans are ready,' Carney told reporters last week. But US trade representative Jamieson Greer struck a different tone in an interview with Fox News, saying, 'We offered them the best deal, they looked at it square in the face and turned around.' Greer added that there has been sparse communication with Canadian officials since talks collapsed in late August.
Trump escalated the rhetoric over the weekend with a series of Truth Social posts. He called Canada's exchange rate with the US 'unacceptable' and shared a map that showed North America—including Canada and Mexico—along with Greenland overlaid with the US flag. He also threatened to halt all US business with Canadian plane maker Bombardier unless it moves its manufacturing south. Bombardier is one of Canada's largest companies, contributing over C$7 billion to annual GDP in 2024, according to a PwC report commissioned by the firm.
'The US currently has in place a 25% tax on Canadian cars and trucks, as well as taxes on Canadian steel, aluminium and lumber. In late August, President Donald Trump imposed new 50% tariffs on other goods like dairy, alcohol, hockey sticks and perfume.'
Both sides say they want a deal, but no movement has been made to resume negotiations. The US-Canada trading relationship, valued at nearly $900 billion in 2025, is the world's largest bilateral trade partnership, and businesses on both sides of the border are scrambling to adapt to the new tariff regime.
