WASHINGTON (TNND) — An advertisement funded by the Government of Ontario has disrupted trade negotiations between the United States and Canada. The ad, which was funded by the Ontario government and is meant to air on major US networks, features a 1987 speech by President Ronald Reagan criticizing tariffs.

“Trade barriers hurt every American worker and consumer,” is one part of the speech heard during the ad, over images of families and industry.

They had apparently enraged President Trump, who imposed a 35% tariff on Canadian goods earlier this summer. In a Truth Social post, Trump labeled the ad as “fake” and declared, “ALL TRADE NEGOTIATIONS WITH CANADA ARE HEREBY TERMINATED.”

The Ronald Reagan Presidential Foundation also responded, claiming the ad misrepresented Reagan’s message and urged viewers to watch the full speech.

“The Ronald Reagan Presidential Foundation and Institute learned that the Government of Ontario, Canada, created an ad campaign using selective audio and video of President Ronald Reagan delivering his “Radio Address to the Nation on Free and Fair Trade,” dated April 25, 1987. The ad misrepresents the Presidential Radio Address, and the Government of Ontario did not receive permission to use and edit the remarks,” part of the statement read.

“Thank you to the Ronald Reagan Foundation for exposing this FRAUD,” Trump wrote in another post.

By Friday Afternoon, Ontario Premier Doug Ford announced that he’d pull the ad from the air on Monday, after it’s likely to air during World Series games over the weekend. Canadian Prime Minister Mark Carney did not directly address the ad but expressed willingness to resume negotiations when the US is ready.

“We can’t control the trade policy of the United States,” Carney said. “We recognize that policy has fundamentally changed lot of progress has been made, and we stand ready to pick up on that progress,” he told reporters before he departed for Asia on an official visit to try and strengthen ties in the region. President Trump will also be making an Asia trip at the same time.

Trump further accused Canada of attempting to “illegally influence the United States Supreme Court” regarding an upcoming ruling on the legality of his tariffs. Kevin Hassett, Director of the National Economic Council, expressed confidence in the Supreme Court siding with the administration.

“I think that we have a very high level of confidence that the Supreme Court will side with us. We think we’re on very strong grounds,” he told reporters Friday.

The Supreme Court is scheduled to hear arguments on the tariff case in early November, which could determine the legality of the president’s tariffs imposed without congressional approval. Some lower courts have ruled against them.
