Trump attacked the ad on Truth Social Friday posting: “CANADA CHEATED AND GOT CAUGHT!!! They fraudulently took a big buy ad saying that Ronald Reagan did not like Tariffs, when actually he LOVED TARIFFS FOR OUR COUNTRY, AND ITS NATIONAL SECURITY.″

President Donald Trump said in a social media post Saturday that a Canadian TV ad criticizing tariffs was a “hostile act,” and in response, “I am increasing the Tariff on Canada by 10% over and above what they are paying now.

U.S. President Donald Trump announced on Thursday that he had terminated trade negotiations with Canada in response to an advert produced by the government of Ontario featuring historic footage of President Ronald Reagan arguing that tariffs undermine economic prosperity.

Reagan saw tariffs as a last resort. For Trump, they are the first step to force scores of countries into high-pressure negotiations.

The Ontario Premier is pulling the TV ad that used former President Ronald Reagan's words to criticize U.S. tariffs, after talking with Canadian Prime Minister Mark Carney.

President Donald Trump in a message posted to Truth Social on Saturday afternoon pledged to increase tariffs on Canada by 10 percent following a dispute over an anti-tariff ad using Ronald Reagan.

Trump slaps Canada with additional 10% tariff over a disputed Reagan ad that aired during World Series, calling it a "fraudulent misrepresentation" of the former president.

The ad, which will stop airing on Monday, used audio of a 1987 address by Ronald Reagan making a case against tariffs.

President Donald Trump canceled trade talks with Canada on Thursday, citing a recent ad released by the government of Canada’s Ontario province that quoted former President Ronald Reagan’s 1987 radio address to the nation on fair trade.
