“Donald Trump announced on Saturday that he will raise US tariffs on [American buyers of goods from] Canada by 10% in retaliation for an anti-tariff advertisement sponsored by the Ontario government, which has further strained one of the world’s largest trade partnerships. The statement, posted on Trump’s Truth Social account, came after several days of public disputes over the ad, which referenced Ronald Reagan’s support for free trade and provoked the US president’s anger. … Trump had previously terminated trade talks with Canada due to the ad.” (10/25/25)
