US President Donald Trump said on Friday that the United States and Canada will not restart trade talks, but Canadian Prime Minister Mark Carney apologised to him for an Ontario political ad using former President Ronald Reagan saying tariffs spell disaster.

“I like him a lot but what they did was wrong,” he said. “He apologized for what they did with the commercial because it was a false commercial.”

Carney did not immediately respond to requests for comment.

Trump last week called off negotiations over the advertisement aired by the Canadian province of Ontario, adding he was increasing tariffs on Canada by an additional 10%.

The ad by the Ontario government featured Republican icon Reagan saying that tariffs on foreign goods while lead to trade wars and job losses. Reagan was known for his support of free markets and free trade.
