Canadian Prime Minister Mark Carney said he told Ontario's premier not to run an anti-tariff ad that angered U.S. President Donald Trump. The ad, which aired in the U.S., criticized Trump's tariffs using a speech by former President Ronald Reagan. Trump ended trade talks with Canada and announced plans to increase tariffs on Canadian imports by 10%. Carney apologized to Trump at the Asia-Pacific Economic Cooperation summit, acknowledging the president was offended. Ontario Premier Doug Ford, a Conservative, pulled the ad last Monday but allowed it to air during the first two games of the World Series.
