Trump raises tariffs on Canada by 10% in retaliation for anti-tariff TV ad

Move is response to ad sponsored by Ontario that referenced Ronald Reagan's support for free trade

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.
