List of products from the United States subject to counter-tariffs effective September 8, 2026
Canada's counter-tariffs on C$27.6bn of US goods took legal effect at 12:01am on Sept 8, covering steel, aluminium, dairy, appliances, agricultural equipment, pulp and paper, plastics and electronics, responding to the 50% US tariff imposed Aug 22. Used as a record of the government's own legal action, which is verifiable and against its own economic interest, not as a self-assessment. The near-term score was already at -8, so retaliation entering force completes the escalation.
