Overview
- President Trump’s administration put 50% tariffs on about US$20 billion of Canadian imports, which went into effect at 00:01 Washington time on Saturday after last‑minute talks in Washington collapsed.
- Canada suspended negotiations and announced it will impose dollar‑for‑dollar retaliatory tariffs on selected U.S. products starting the Tuesday after Labor Day, with Ottawa flagging steel, dairy, appliances, farm equipment, pulp and paper, and electronics as likely targets.
- U.S. officials applied the duties under Section 338 of the 1930 Tariff Act, a rarely used legal authority that lets customs impose steep unilateral tariffs without a prior investigation.
- The collapse followed intense, days‑long bargaining over cuts that reportedly would have reduced some U.S. tariffs on Canadian steel, aluminum and autos, with negotiators disputing late changes to the deal and blaming each other for the breakdown.
- Business groups warn the escalation will raise costs for consumers, disrupt North American supply chains and complicate USMCA discussions, while Brazil separately has invoked its Economic Reciprocity Law and reopened high‑level talks with U.S. trade officials to contest American duties.
