What Canada’s retaliatory tariffs cover
Canada applies one of three tariff rates to each covered product — 15%, 25%, or 50% — matching the rate the United States applies to the equivalent Canadian good under Section 338 or Section 232.
The product list covers more than 700 US-origin products, across sectors including steel, aluminum, dairy, appliances, agricultural equipment, pulp and paper, plastics, electronics, seafood, cheese, clothing, cosmetics, toilet paper, alcoholic beverages, textiles, tech products, and toys.
This guide doesn’t reproduce the product list or specific HS codes inline — see the official Canada Department of Finance product list on canada.ca for the complete, current list and applicable HS codes.
Country of origin determines coverage
Coverage is based on the country of origin of the good — where it was made — not where it ships from. This is the same rule the US applies under its Section 338 tariff on Canadian goods.
Steel, aluminum, and automotive: existing tariffs, not new ones
Two categories sit outside the new 15/25/50 tiered list — they’re handled through Canada’s existing tariff actions rather than as part of this action.
- Steel and aluminum: Canada’s existing counter-tariff on US steel and aluminum increases from 25% to 50%, matching the new US rate. This is a rate increase on the existing tariff, not a separate or stacked tariff.
- Automotive: Canada’s existing counter-tariff on US-made vehicles continues to apply, unchanged by this action. It is not part of the new tiered list.
Timing: what triggers the tariff
Canada’s retaliatory tariffs apply to covered goods as of 12:01 a.m. on September 8, 2026.
What this means for your shipments
If you sell or ship US-origin goods into Canada, check the following:
- Whether the product appears on the Canada Department of Finance product list, and which of the three rate tiers (15%, 25%, or 50%) applies
- The confirmed country of origin of the product, as distinct from where it ships from
- Whether the product is steel, aluminum, or a motor vehicle — those are handled under Canada’s existing tariff actions, not the new tiered list
- Whether the shipment was already in transit as of September 8, 2026, since in-transit goods are exempt

What are the tariff rates?
15%, 25%, or 50%, depending on the product — each rate matches the rate the US applies to the equivalent Canadian good under Section 338 or Section 232.
How much trade does this affect?
Estimates vary by source. Canada’s Finance Minister has cited a figure near USD $20 billion; other reporting citing the Canada Department of Finance product list context puts the figure closer to USD $27.6 billion. Affected trade is in the tens of billions of dollars.
Does this apply based on where a shipment comes from, or where the product was made?
Country of origin — where the good was made — not where it ships from.
Are steel, aluminum, and automotive tariffs part of this new action?
No. Steel and aluminum are covered by Canada’s existing counter-tariff, which increases from 25% to 50% to match the new US rate — a rate increase, not a new or stacked tariff. Canada’s existing counter-tariff on US-made vehicles continues to apply, unchanged by this action.
Are goods already in transit on September 8 covered?
No. Goods already in transit on September 8, 2026 are exempt.
