Overview
- Negotiations broke down late Friday and the U.S. 50% Section 338 duties on roughly $20–28 billion of Canadian goods took effect early Saturday, covering items from liquor and dairy to certain building materials and clothing.
- Prime Minister Mark Carney announced he had recalled negotiators, suspended talks and vowed to match U.S. levies dollar for dollar to protect workers and businesses.
- Washington and Ottawa traded blame: the U.S. Trade Representative said Canada walked away from agreed terms while Carney said U.S. negotiators proposed last‑minute, unfair changes that undercut a deal.
- Business groups warned the duties will disrupt integrated North American supply chains and raise consumer costs, and experts say the novel use of Section 338 makes expensive, likely litigation almost certain.
- The collapse complicates follow‑on talks over USMCA matters and exposed domestic constraints in Canada — notably provincial liquor procurement rules and dairy protections — that limited Ottawa’s bargaining room.
