US President Donald Trump said on Saturday he was increasing tariffs on Canada by an additional 10% “above what they’re paying now,” as he reacted again to an ad by Canada’s Ontario province, a day after it was aired during the World Series broadcast.

Trump on Thursday ended trade talks with Ottawa over the tariff-related ad, which Trump said was misleading.

Trump announced the higher tariffs in a Truth Social post on Saturday, referencing the ad, which features a video of former President Ronald Reagan, a Republican icon, saying that tariffs cause trade wars and economic disaster. The ad had already been running for some days before Trump first reacted to it on Thursday night.

Ontario Premier Doug Ford said on Friday that after discussions with Canadian Prime Minister Mark Carney, Ontario would pause the US ad campaign on Monday so that trade talks could resume.

The advertisement aired on Friday during the broadcast for Game 1 of Major League Baseball’s World Series, in which the Toronto Blue Jays are facing off against the Los Angeles Dodgers. “Their Advertisement was to be taken down, IMMEDIATELY, but they let it run last night during the World Series, knowing that it was a FRAUD,” Trump posted.

“Because of their serious misrepresentation of the facts, and hostile act, I am increasing the Tariff on Canada by 10% over and above what they are paying now,” he wrote.

Trump posted the message while he was aboard Air Force One on his way to Malaysia, the first stop on a trip through East Asia that will largely focus on trade issues.

The US Commerce Department, the White House and the office of the Canadian prime minister did not immediately respond to requests for comment.
