Premier Doug Ford said the U.S. ambassador's expletive-laced tirade was “absolutely unacceptable” and “unbecoming of an ambassador."

Ontario Premier Doug Ford called on US Ambassador Pete Hoekstra to say he’s sorry for cursing in public at the Canadian province’s trade representative over a television ad that riled up Trump.

TORONTO — Ontario Premier Doug Ford says the U.S. ambassador to Canada should apologize to Ontario's representative in Washington after sources say he shouted profanely about the province's anti-tariff ad.

In his first campaign to lead Ontario, Ford started out as a Trump-style populist. But tariffs changed his view and he is now a consistent thorn in the U.S. president's side.

Doug Ford said that the Reagan ad that derailed trade talks with Trump is the "best ad that ever ran," as Canada courts Asia for new trade relations.

Premier Doug Ford is calling on U.S. Ambassador Pete Hoekstra to apologize to Ontario’s representative in Washington, after Mr. Hoekstra reportedly delivered a public expletive-filled tirade to the official over the province’s anti-tariff advertisement.

Calling it “the best ad I ever ran,” the populist Conservative premier said the campaign accomplished its goal of drawing attention to Trump’s trade policies. The ad angered Trump, who responded by threatening to raise tariffs on Canadian imports by another 10%.

The premier said the advert was viewed one billion times as Trump said he has no plans to meet with his Canadian counterpart.
