Donald Trump announced a new 50% tariff on automobiles and crucial raw materials from Canada, the latest deterioration in trade relations between the two neighbors with historically strong economic ties.

The US president said that the increased tariffs would start on 1 January 2027 on all cars, trucks, automobile parts and steel. He also derided the nation’s tariffs on American farmers, writing on social media that Canada has been “ripping off” the US “for years”.
