What Tariffs Is Canada Introducing?
Under the new measures, Canada will impose three different tariff rates:
- 15%
- 25%
- 50%
The rate applied to each product will correspond to the applicable U.S. tariff rate.
The Canadian government says the measures are designed to match the U.S. Section 338 and Section 232 tariffs affecting Canadian products.
Which U.S. Products Will Face the New Tariffs?
The new counter-tariffs focus on sectors that Ottawa says have been most affected by U.S. tariffs.
These include:
- Steel
- Dairy products
- Appliances
- Agricultural equipment
- Pulp and paper
- Electronics
Some products will face a 25% tariff, including certain appliances and dairy products such as cheese.
Certain steel and aluminum products will face tariffs of up to 50%.
Furniture and clothing and apparel are also among the products subject to 50% counter-tariffs.
Why Is Canada Introducing These Measures?
The federal government says the counter-tariffs are intended to protect Canadian workers, producers and manufacturers affected by U.S. tariffs.
By placing additional costs on selected U.S. products entering Canada, Ottawa says Canadian producers can compete on a more level playing field in the domestic market.
The measures are part of Canada's broader response to the latest escalation in Canada-U.S. trade tensions.
When Do the New Tariffs Take Effect?
The new counter-tariffs become effective at 12:01 a.m. on September 8, 2026.
However, the measures do not apply to U.S. goods that are already in transit to Canada on the day the tariffs come into force.
The Canada Border Services Agency will provide additional information on how the new tariffs will be administered.
How Much Trade Is Affected?
The new counter-tariffs apply to products representing approximately $27.6 billion in imports from the United States.
The government has specifically focused the measures on industries considered particularly vulnerable to the latest U.S. tariffs.
The move means businesses importing affected American products into Canada will need to account for the additional tariff costs.
Canada Is Also Supporting Affected Businesses
Canada's tariff response goes beyond the new import duties.
The federal government has announced a $7.5 billion package of new and enhanced measures designed to support Canadian workers and businesses affected by U.S. tariffs.
The package builds on nearly $25 billion in support that the government says it has already provided since the implementation of U.S. tariffs.
One part of the package includes an additional $1.5 billion through the Regional Tariff Response Initiative to help small and medium-sized businesses manage tariff-related pressures.
What About Existing Canadian Tariffs?
The new measures do not replace all of Canada's existing counter-tariffs.
The government says other counter-tariffs against U.S. products, including those covering automobiles, remain in place.
Canada's tariff remission framework also remains available for businesses seeking exceptional relief in certain circumstances.
What Could This Mean for Canadian Businesses?
The impact will vary depending on the products businesses import from the United States.
Companies that rely heavily on affected American goods could face higher import costs once the new tariffs take effect.
Businesses may respond by looking for Canadian suppliers, sourcing products from other countries or adjusting their supply chains.
For Canadian manufacturers, the government's objective is to strengthen their competitive position against affected U.S. imports.
The Bigger Canada-U.S. Trade Picture
The latest tariffs add another layer of uncertainty to the economic relationship between Canada and the United States.
The two countries have deeply integrated supply chains, meaning changes in tariffs can affect manufacturers, suppliers, retailers and consumers on both sides of the border.
Canada's government says it is also working to diversify trade and strengthen domestic supply chains as it responds to the changing international trade environment.
What Happens Next?
The immediate focus will be on the implementation of the new tariffs on September 8.
Canadian importers will need to determine whether their products fall within the affected tariff classifications and which rate applies.
The government's response could also evolve depending on future U.S. trade measures and developments in Canada-U.S. negotiations.
For businesses and consumers, the key question will be whether the latest tariff escalation remains temporary or becomes part of a longer period of trade uncertainty between the two countries.
