Earlier, the US president ended trade talks with Ottawa over the commercial, which he said was misleading

US President Donald Trump has imposed an additional 10% tariff on Canadian goods for airing an anti-tariff commercial that he described as "fraudulent."

Trump has long defended tariffs as a way to counter what he calls unfair trade practices by countries including China, Canada, and Mexico, which he says harm US industries. Earlier this year, he imposed 25% tariffs on Canadian steel and aluminum before later expanding them to 35% on a broader range of goods, including timber and cars, as part of the wider campaign.

The announcement came two days after Trump said he terminated trade talks with Canada over a commercial aired in Ontario that used quotes by former US President Ronald Reagan to criticize Trump's tariffs. In a Truth Social post on Saturday, Trump said Canada was caught red-handed running "a fraudulent advertisement," claiming that "selective audio and video" were used to misrepresent Reagan.

"The sole purpose of this FRAUD was Canada's hope that the United States Supreme Court will come to their 'rescue' on tariffs that they have used for years to hurt the United States," he wrote, referring to the court's upcoming review of his tariff authority. The Supreme Court is set to hear the case in November after lower courts ruled that his broad tariffs on Canada, Mexico, and other countries are unconstitutional.

Trump also criticized Canada for not removing the commercial immediately, claiming that "Ronald Reagan LOVED tariffs." "Because of their serious misrepresentation of the facts and hostile act, I am increasing the Tariff on Canada by 10% over and above what they are paying now," he said.

Ontario Premier Doug Ford said on Friday that the province will pause its anti-tariff ad campaign in the US after discussions with Prime Minister Mark Carney "so that trade talks can resume."

Carney has not commented on the latest measure. After trade negotiations were suspended earlier in the week, he said Ottawa "stands ready" to resume talks "for the benefit of workers in both our countries." Conservative Leader Pierre Poilievre accused the prime minister of missing his own summer deadline to secure a deal.
