On November 6, 2025, Canadian Prime Minister Mark Carney privately apologized to U.S. President Donald Trump for an Ontario-produced political ad criticizing Trump's tariffs, which Trump deemed false. The ad, featuring Ronald Reagan's 1987 speech warning against tariffs, led Trump to suspend trade talks and increase tariffs on Canadian goods. Carney opposed the ad and urged Ontario Premier Doug Ford not to air it. Despite tensions, Carney and Trump maintained a cordial relationship during a recent Asia-Pacific summit.
