Canada is escalating its trade response to the United States, announcing counter-tariffs of 15%, 25% and 50% on U.S.-origin goods covering $27.6 billion in imports.
The measures take effect at 12:01 a.m. on September 8, 2026 and are designed to match U.S. tariffs imposed on Canadian products.
The Canadian government describes the response as “dollar for dollar.”
Why Canada Is Imposing the Tariffs
The countermeasures follow the United States’ decision to impose a 50% tariff on $27.6 billion of Canadian goods, effective August 22, 2026.
According to Canada’s Department of Finance, the new Canadian tariffs are drawn from products targeted by U.S. Section 338 and Section 232 tariffs.
Rather than applying one uniform rate, Canada will impose tariffs of 15%, 25% or 50%, with the rate for individual products based on the corresponding U.S. tariff applying to the same goods.
This creates a deliberately reciprocal structure: Canada says it intends to match the U.S. measures on a dollar-for-dollar basis.
$27.6 Billion of U.S. Imports Targeted
The Canadian counter-tariffs will cover approximately $27.6 billion of imports from the United States.
The government says the measures focus particularly on sectors affected by the U.S. tariffs, including:
- Steel
- Dairy products
- Appliances
- Agricultural equipment
- Pulp and paper
- Electronics
However, the detailed tariff schedule extends across a considerably broader range of products.
The published list includes hundreds of tariff classifications and covers goods ranging from industrial materials and machinery to consumer products.
Some Products Face a 50% Tariff
The highest counter-tariff rate is 50%.
Among the products appearing in the Canadian tariff schedule at this rate are certain milk and cream products, whey products, natural honey, perfumes, cosmetics and beauty preparations, plastics, plywood and various paper and pulp products.
Cheese products, meanwhile, are among goods generally listed with a 25% tariff, while other products across the schedule are subject to rates of 15%, 25% or 50%.
The applicable rate therefore depends on the specific tariff classification rather than simply the broader product category.
Origin Will Be Critical
The measures apply specifically to goods originating in the United States.
For purposes of the counter-tariffs, Canada states that U.S.-origin goods are those eligible to be marked as goods of the United States under the Determination of Country of Origin for the Purpose of Marking Goods (CUSMA Countries) Regulations.
This makes origin analysis particularly important for businesses operating integrated North American supply chains.
A product imported from the United States will not necessarily be subject to the surtax merely because it was shipped from a U.S. location. Businesses will need to determine the origin of the goods under the applicable Canadian rules and identify the precise tariff classification.
Goods Already in Transit Are Excluded
Canada has provided an important transitional rule.
The countermeasures will not apply to U.S. goods that are already in transit to Canada on September 8, 2026, when the tariffs enter into force.
Further administrative guidance is expected through the Canada Border Services Agency.
For businesses with shipments scheduled around the implementation date, documentation establishing when goods entered transit may therefore become particularly relevant.
What Businesses Should Review
Companies importing U.S. goods into Canada have a short window before the September 8 implementation date.
Importers should review their Canadian tariff classifications against the government’s published list, confirm whether goods qualify as U.S.-origin products and identify the applicable 15%, 25% or 50% rate.
Businesses may also need to assess the effect of the tariffs on existing purchase agreements, pricing, customs valuation, landed costs and supply chains.
For groups operating across Canada and the United States, the measures add another layer of complexity to cross-border sourcing decisions.
A New Stage in the Canada-U.S. Tariff Dispute
The scale and structure of the measures underline the increasing use of tariffs as reciprocal trade instruments between the two countries.
Canada has explicitly tied its $27.6 billion countermeasure package to the equivalent value of Canadian goods affected by the latest U.S. action.
Unless the underlying trade measures change, importers will therefore enter September facing substantially higher customs costs on a wide range of U.S.-origin goods.
The counter-tariffs take effect on September 8, 2026.
