September 8, 2026

On September 7, 2026 the Canada Border Services Agency (CBSA) published a Customs Notice to provide information on the application of the United States Surtax Order (2026), specifically regarding surtax provisions effective September 8, 2026, on certain goods originating in the United States (U.S.).

The surtax is introduced by Canada in response to the U.S.' imposition of Section 338 tariffs on goods imported into the U.S. from Canada.

The goods subject to Canada's surtax are drawn from those targeted by U.S. Section 338 and Section 232 tariffs, with the surtax applicable to each product generally corresponding to the U.S. tariff rate.
