Overview
- Negotiations broke down late Friday and the United States put 50% duties on roughly $20–28 billion of Canadian goods that took effect on Saturday, using a rarely used Section 338 authority.
- Prime Minister Mark Carney recalled Canada’s negotiators and said Ottawa walked away because the U.S. made last‑minute demands that would have limited Canada’s trade freedom and even touched French language and Quebec cultural protections.
- Canada has pledged matching, dollar‑for‑dollar counter‑tariffs that will begin on Sept. 8 and said it will roll out targeted levies and supports for affected workers and businesses.
- The U.S. list covers more than 500 product categories, including alcohol, dairy, electronics, lumber and sporting goods, and business groups warn the levies will raise prices and disrupt integrated auto, manufacturing and food supply chains.
- The dispute has escalated into sharp public rhetoric from President Trump and U.S. officials, prompted warnings from governors in border states and set up likely legal fights over the use of Section 338 and the future of North American trade ties.
