Canada has announced retaliatory tariffs on US goods effective September 8, 2026. The official item-level list has not been published yet.
What is confirmed so far: after US 50% tariffs on roughly US$20 billion of Canadian goods took effect on August 22, 2026, the Prime Minister announced Canada will match the US measures dollar for dollar beginning September 8. Reporting on the announcement indicates targeted categories are expected to include steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics — but until the Order in Council and CBSA customs notice are published, no item-level list exists.
What this page will do
The day the official list is published, this page becomes a searchable checker: look up your product or HS heading and see whether it is covered, the surtax rate, the effective date, and which relief routes (remission, drawback, duties relief) may apply.
