A Canadian province said on Friday it would pull an anti-tariff ad featuring former US president Ronald Reagan that prompted current leader Donald Trump to scrap trade talks.

Trump announced on his Truth Social network on Thursday that he had "terminated" all negotiations with Canada over what he called a "fake" ad campaign by the Ontario province that he said misrepresented fellow Republican Reagan.

Less than a day later, Ontario Premier Doug Ford said he was suspending the ads after talking to Canadian Prime Minister Mark Carney about the spiralling row with Washington.

"In speaking with Prime Minister Carney, Ontario will pause its US advertising campaign effective Monday so that trade talks can resume," Ford said in a post on X.

Ford added he had told his team to keep airing the ad during the first two games this weekend of baseball's World Series -- in which a Canadian team, the Toronto Blue Jays, face the Los Angeles Dodgers.

The Canadian ad used quotes from a radio address on trade that Reagan delivered in 1987, in which he warned against the ramifications that he said high tariffs on imports could have on the US economy.

It cited Reagan as saying that "high tariffs inevitably lead to retaliation by foreign countries and the triggering of fierce trade wars," a quote that matches a transcript of his speech on the Ronald Reagan Presidential Library's website.

Trump, however, vented his fury at the ad, saying it was designed to "interfere with the decision of the US Supreme Court," which is due to rule on his sweeping global tariffs.

"CANADA CHEATED AND GOT CAUGHT!!!" he said in a new post as he doubled down earlier Friday.

Carney had earlier sought to calm the situation, saying that his country was ready to resume "progress" on trade talks "when the Americans are ready".

Canada has "to focus on what we can control, and realise what we cannot control," he added. (AFP)
