Fentanyl, a Reagan ad and a near deal: Trump's trade war with Canada

Canada’s planned retaliation against U.S. goods took effect Tuesday, with tariffs ranging from 15% to 50% on up to $20 billion of products coming from President Donald Trump’s biggest trading partner. The measures are part of a tariff war that began shortly after Trump returned to office in January 2025 and has hit steel, aluminum, automobiles, lumber and other sectors. A timeline includes Trump’s February 1 tariff announcement, a 30-day pause agreed after U.S. and Canadian moves, and later U.S. actions on steel, aluminum, and autos. The latest update keeps negotiations in focus after Trump and Prime Minister Mark Carney set a 30-day deal target at the G7.
