US President Donald Trump said on Thursday all trade talks with Canada were terminated following what he called a fraudulent advertisement in which former and late President Ronald Reagan spoke negatively about tariffs.

Axar.az informs, citing Reuters, Trump imposed tariffs on Canadian steel, aluminum and autos earlier this year, prompting Ottawa to respond in kind. The two sides have been in talks for weeks on a potential deal for the steel and aluminum sectors.

“Based on their egregious behavior, ALL TRADE NEGOTIATIONS WITH CANADA ARE HEREBY TERMINATED,” Trump wrote on Truth Social.

Ontario Premier Doug Ford said earlier this week the ad from his province with anti-tariff messaging had caught Trump’s attention. The ad showed Reagan, a Republican, criticizing tariffs on foreign goods while saying they caused job losses and trade wars.

“I heard that the president heard our ad. I’m sure he wasn’t too happy,” Ford said on Tuesday.

The Ronald Reagan Presidential Foundation issued a statement late on Thursday saying the ad by the government of Ontario was “using selective audio and video” of Reagan and that the foundation was reviewing its legal options.

“The ad misrepresents the Presidential Radio Address (by Reagan in 1987), and the Government of Ontario did not seek nor receive permission to use and edit the remarks,” the foundation said in its statement.
