Trade and Tariffs

The Canada–U.S. trade environment continues to change rapidly, with tariffs affecting Canadian exporters, importers, manufacturers and businesses that rely on cross-border supply chains. On August 25, 2026, the Government of Canada announced a $7.5-billion package of new and enhanced measures to support Canadian businesses and workers affected by U.S. tariffs, building on nearly $25 billion in tariff-related supports previously provided.

Tariff treatment now varies by product, sector, country of origin and eligibility under the Canada–United States–Mexico Agreement (CUSMA). Businesses should confirm the tariff treatment that applies to their specific goods rather than relying on a single tariff rate for all Canadian exports. Learn more about current U.S. tariffs affecting Canadian goods.

Key current U.S. tariff measures affecting Canadian businesses include:

1. A 10% tariff under Section 301 of the U.S. Trade Act on imports of most goods, including goods from Canada, effective July 24, 2026. Goods that qualify for preferential treatment under CUSMA remain exempt from this tariff.
2. 50% tariffs under Section 338 of the U.S. Tariff Act on a range of Canadian products, effective August 22, 2026. There is no CUSMA exemption from these Section 338 tariffs.
3. Additional U.S. sector-specific tariff measures also apply to certain products. Businesses should use the Government of Canada and Trade Commissioner Service resources below to confirm current product-specific requirements.

Because different U.S. tariff measures have different eligibility rules and exemptions, businesses should check the Harmonized System (HS) classification, country of origin and CUSMA status of their goods before making importing, exporting, sourcing or pricing decisions.

Effective September 8, 2026, Canada will impose counter-tariffs of 15%, 25% and 50% on products covering $27.6 billion in imports from the United States, with individual product rates based on the corresponding U.S. tariff. The measures focus on sectors including steel and aluminum, dairy, appliances, agricultural equipment, pulp and paper, plastics and electronics.
