Donald Trump makes announcement in response to anti-tariff ad sponsored by Ontario government. Key US politics stories from Saturday 25 October at a glance
Donald Trump announced on Saturday that he will raise US tariffs on 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.
