ABOARD AIR FORCE ONE - On Saturday, President Donald Trump announced plans to increase tariffs on Canadian imports by an additional 10% in response to an anti-tariff television advertisement broadcast by Ontario.

The backstory:

The ad used the words of former President Ronald Reagan to criticize U.S. tariffs, angering Trump who said he would end trade talks with Canada. Ontario’s Premier Doug Ford said he would pull the ad after the weekend, and it ran Friday night during the first game of the World Series.

President Donald Trump said he is ending ?all trade negotiations? with Canada after a television ad sponsored by one of its provinces used a quote from former President Ronald Reagan to criticize U.S. tariffs The ad drew backlash from the White House, and the province?s leader later withdrew it following Trump?s remarks. POLITICO trade reporter Ari Hawkins joins LiveNOW from FOX?s Christina Evans to discuss the fallout and what it could mean for U.S.?Canada relations.

What they're saying:

"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 said in a post on his Truth Social platform as he flew aboard Air Force One to Malaysia.

"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."

What's next:

Trump and Canadian Prime Minister Mark Carney will both attend the Association of Southeast Asian Nations summit in Malaysia. But Trump told reporters traveling with him that he had no intention of meeting Carney there.
