Overview
- Canada put dollar‑for‑dollar counter‑tariffs into force on September 8, applying 15–50% duties on selected U.S. goods such as steel, aluminum, dairy and other items valued at about $20–27.6 billion, after talks with Washington collapsed.
- The U.S. response has moved beyond duties: the White House ordered Canadian products removed from federal procurement schedules, announced presidential decrees that ban certain Canadian imports effective September 29, and said it may raise further auto duties from January 1, 2027.
- President Trump publicly threatened to bar Bombardier from the U.S. market, a step whose legal basis is unclear and whose practicality is questioned because Bombardier already has sizable U.S. operations and suppliers.
- Economists and industry sources warn the measures endanger tightly integrated North American supply chains in autos, aerospace, energy, agriculture and manufacturing and could quickly disrupt jobs and production on both sides of the border.
- The dispute is politically charged in the U.S., where partisan opinion on Canada has hardened and lawmakers from both parties have signaled concern, while Ottawa says it is open to talks though it stands ready to defend Canadian sovereignty and trade rules.
