Canadian Prime Minister Mark Carney says he would retaliate against any new U.S. tariffs on Canadian goods

WASHINGTON (NBC, KYMA) - President Donald Trump Monday hit back at Canadian Prime Minister Mark Carney, who on Friday had announced he would retaliate against any new U.S. tariffs on Canadian goods.

Writing on social media, President Trump threatened to hit imported cars, trucks, automobile parts and steel with 50% tariffs starting January 1, 2027.

"Canada has been ripping off the United States of America for years," Trump wrote.

Canada ranks as the third-highest source of U.S. imports. In 2025, more than $380 billion worth of goods were brought over the border, according to U.S. Census Bureau data.

Monday's escalation follows a wave of new tariffs that hit Canada early Saturday after weeks long negotiations between Washington and Ottawa broke down.

Prime Minister Carney pulled Canadian negotiators out of those talks late Friday after he said the U.S. proposed new terms that were uneconomic and unfair.

Those 50% duties, which came into effect at 12:01 a.m. Saturday, which included a wide variety of Canadian goods, from hockey sticks to building materials.

In Carney's view, however, Canada has been attacked by the United States, which for decades has been one of its closest partners and allies.
