President Donald Trump said Thursday night that he was terminating all U.S. trade negotiations with Canada because the Ontario provincial government aired an ad featuring former President Ronald Reagan speaking negatively about tariffs.

Trump’s announcement came after The Ronald Reagan Presidential Foundation and Institute said that the ad by Ontario’s government misrepresents a presidential radio address that Reagan delivered in April 1987, and that his remarks were edited without permission.

The foundation did not say what was misleading, but encouraged people to listen to an unedited video of his address on its YouTube channel.

“The Ronald Reagan Foundation has just announced that Canada has fraudulently used an advertisement, which is FAKE, featuring Ronald Reagan speaking negatively about Tariffs,” Trump wrote in a Truth Social post. “They only did this to interfere with the decision of the U.S. Supreme Court, and other courts.”

“TARIFFS ARE VERY IMPORTANT TO THE NATIONAL SECURITY, AND ECONOMY, OF THE U.S.A. Based on their egregious behavior, ALL TRADE NEGOTIATIONS WITH CANADA ARE HEREBY TERMINATED,” Trump wrote. “Thank you for your attention to this matter!”

Ontario Premier Doug Ford on Oct. 14 said the province would spend $75 million on ads to run in the United States featuring Reagan criticizing tariffs.

“And we’re going to repeat that message to every Republican district there is right across the entire country,” said Ford, who called himself a “big Ronald Reagan fan.” 

Ford posted the ad on X on Oct. 16.

On the ad, Reagan is heard saying, over images of American landscapes, domestic scenes, and workplaces,”When someone says, ‘Let’s impose tariffs on foreign imports,’ it looks like they’re doing the patriotic thing by protecting American products and jobs.”

“And sometimes for a short while it works, but only for a short time,” Reagan says. “But over the long run, such trade barriers hurt every American worker and consumer.

Trump has made tariffs a centerpiece of his second term in the White House.

The Supreme Court in November is set to hear arguments in a case that will determine whether Trump had the power to impose many of his wide-ranging tariffs.
