The Trump administration is lifting some of its 50% tariffs on Canadian goods two weeks before the midterm elections, after a Republican candidate in a key Senate race said she had lobbied for the change.

Starting on 30 October, tariffs will be eased on products including “plywood sheets, some paper products, certain machinery and refrigeration equipment,” the White House said on Friday.

Republican Senator Susan Collins, who is in a tight race to keep her seat in Maine, first announced the exemptions, saying they would help her state’s agriculture industry.

The US imposed a 50% levy on $20bn (£15bn) of Canadian goods after trade talks between the two countries collapsed in August.

Canada has imposed a series of countermeasures against US tariffs, which Prime Minister Mark Carney said were “necessary to protect our workers”.

Last month, Carney matched the US tariffs “dollar for dollar” after the breakdown in talks. Trump had imposed them for what he called “unequal treatment” of US cars, dairy and alcohol.

Canada did not immediately respond to the White House’s announcement on Friday.

The White House said while tariffs would be lifted from some items, including some packing crates and boxes, they would be introduced on other items such as carpets and “waste products”.

It said the action reflected President Trump’s “continued efforts to defend American workers and ensure fair trade”.

Collins, meanwhile, said she had repeatedly asked senior Trump officials for tariff relief and that she would “continue working directly with administration officials to seek additional relief and encourage a broader trade agreement with Canada, our neighbour, ally, and largest trading partner”.

She wrote on X that the tariff exemptions were on products that were “crucial to Maine’s agricultural industries, including blueberry, potato, apple, and seaweed producers”.

Collins’ Democratic challenger, Troy Jackson, responded: “Trump’s trade wars have made life harder and more expensive for Mainers. Susan Collins enabled this chaos, voted to confirm the people behind it, and now wants credit for bringing a cup of water to put out the fire.”

​Maine’s economy, as well as that of other border states, is deeply linked to Canada and they have felt the effects of the month-long trade war.

Michigan lawmaker Mike Rogers, also a Republican, has called on Trump to end the standoff after spending months supporting the policy in recent advertisements airing in his trade-reliant state.

Also on Friday, President Donald Trump said Canada was “working very hard” on a ⁠trade ​deal with the US.

Carney, for his part, said that Canada was open to a mutually beneficial deal, but is willing to wait it out.

“We could sign it this afternoon if the US were there. If it has to be months from now or longer than that, or another administration, before a proper deal comes into place, we will do that,” he said on Friday, according to Canadian broadcaster CBC.

Canada’s internal trade minister Dominic LeBlanc confirmed on Thursday that a delegation met with members of the Canada-United States Economic Relations Advisory Committee – the ninth meeting since April 2026. The committee members discussed the ongoing impact of US tariffs in Canada.

LeBlanc’s office did not immediately respond on Friday to the BBC’s request for comment.
