Canada-US Trade War Escalates as Tariffs Imposed on $20 Billion Worth of Goods

The once-close and durable alliance between Canada and the United States has been fundamentally altered due to the collapse of trade talks, leading to a full-scale trade war. Canadian Prime Minister Mark Carney acknowledged this break, stating that 'America has changed' and the countries would 'not return to our old relationship.'

The U.S. imposed 50% tariffs on about $20 billion worth of Canadian goods early Saturday, with Canada retaliating dollar for dollar beginning September 8, targeting sectors including steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics.

Carney had warned at the World Economic Forum in Davos in January that the world was experiencing 'a rupture, not a transition,' urging countries to reduce their vulnerability to economic coercion by strengthening their economies at home and diversifying abroad. He accused the U.S. of using 'economic integration as a weapon' and said its approach was 'not sustainable.'

Royal Bank of Canada economists estimate that the tariffs directly affect about 0.4% of Canada's GDP, but the damage could grow if retaliation broadens or more sectors are targeted.
