President Donald Trump has canceled trade negotiations with Canada over what he called a “fake” ad that featured parts of an anti-tariff speech delivered by conservative hero and former President Ronald Reagan.

Doug Ford agreed to pull the controversial ad, but it will still air through the weekend’s Blue Jays–Dodgers World Series games, which Trump denounced as ‘fraud’ and ‘dirty playing’

Trump abruptly terminated talks after Ontario ran an ad campaign using videos of President Ronald Reagan denouncing tariffs.
