Ontario Premier Doug Ford is calling on U.S. Ambassador to Canada Pete Hoekstra to apologize following an expletive-ridden exchange he reportedly aimed at the province’s trade representative.

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.

Premier Doug Ford says U.S. Ambassador to Canada Pete Hoekstra should apologize to Ontario's trade representative over a reported expletive-laden tirade.

U.S. ambassador Pete Hoekstra angrily complained to David Paterson, Ontario’s Washington point person about Ford’s anti-tariff ad, sources told the Star.

Ford, Canada’s most successful populist politician, has stolen the spotlight from Prime Minister Mark Carney as the country’s most outspoken crusader against President Donald Trump’s trade war.

Doug Ford has built a reputation for picking fights with President Trump and getting under his skin with publicity-grabbing moves as U.S. tariffs have harmed Ontario’s economy.

President Trump announced Saturday he would place a new 10 percent tariff on Canada after he accused Ontario Premier Doug Ford of launching a misleading ad featuring President Ronald Reagan discussing tariffs.
