What Is a Tariff? How Import Duties Work in Canada (Updated November 13, 2026)

Verified and updated: November 13, 2026, 4:00 a.m. UTC.

Canada’s tariff measures show why the word “tariff” matters beyond trade negotiations: customs duties can change the cost of bringing particular goods across a border. As of September 8, 2026, Canada applies counter-tariffs of 15%, 25% or 50% to specified U.S.-origin products, with the rate tied to the corresponding U.S. measure. The list includes goods in sectors such as steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics. The duty is assessed on covered imports; whether it affects a Canadian shopper’s price, and by how much, depends on businesses’ costs and pricing decisions.

Destaques

• A tariff is a customs duty charged on an imported good, usually based on its classification, origin and value.
• The importer generally pays the duty at the border; the foreign seller does not automatically pay it.
• A tariff can raise a business’s costs, but its effect on retail prices depends on how costs are absorbed or passed along.
• Canada’s current counter-tariffs apply only to listed products that meet the applicable U.S.-origin rules.

What is a tariff?

A tariff is a tax or duty imposed by a government on certain goods imported from another country. It is collected when the goods enter the importing country, under that country’s customs laws. A tariff can be a percentage of a good’s customs value, a fixed amount per unit, or a combination of the two. The tariff schedule specifies which rate applies to each product category.

Tariffs differ from sales taxes. A tariff is tied to importing a product, while a sales tax is generally charged on a sale or transaction under separate rules. An imported product could be subject to customs duty and, where applicable, other taxes or fees.

How does a tariff work at the border?

Before an import can be assessed, it must be described and classified under the importing country’s tariff system. In Canada, the tariff classification and the product’s country of origin help determine the applicable rate. Origin is not always the same as the country from which a shipment was sent: manufacturing and trade-agreement rules can affect origin. The importer or its customs broker reports the information, and border authorities administer the entry and collect amounts owing.

For a simple example, assume a shipment has a customs value of C$10,000 and the applicable tariff rate is 10%. The basic duty would be C$1,000, before accounting for other taxes, fees, adjustments or special measures. Actual calculations depend on the product’s classification, customs value, origin and the rules in force when it is imported.

Canadian importers can consult the Canadian Customs Tariff and government guidance on tariffs and tariff classification. The rate is product-specific; a broad description such as “electronics” is not enough to identify the duty for a particular item.

Who pays a tariff?

The importer of record is generally responsible for paying customs duties to the importing government. For a Canadian retailer importing merchandise, that means the retailer or its customs representative handles the border payment. The exporting country’s government does not normally send the tariff bill to the foreign manufacturer.

That legal responsibility does not settle who ultimately bears the economic cost. An importer might absorb some of the duty in its margins, negotiate a lower price with a supplier, change suppliers, or raise its selling price. The result depends on competition, contracts, supply availability and consumer demand. That is why a tariff rate should not be treated as a guaranteed, one-for-one increase in a store price.

Why do governments impose tariffs?

Governments may use tariffs to raise revenue, protect domestic producers from import competition, or respond to another country’s trade measures. A tariff can give local producers more room to compete, but it can also make imported inputs more expensive for businesses that rely on them. Trading partners may retaliate, affecting exporters and supply chains on both sides.

Canada’s September 2026 counter-tariffs are a current example of a trade response. Finance Canada says the measures cover specified U.S.-origin products and use rates of 15%, 25% and 50% corresponding to U.S. tariffs on the same goods. The department also notes that the product list and rates are subject to change, so importers should check current official guidance before relying on a rate. Finance Canada’s announcement

What could happen next?

Future effects depend on policy decisions and how companies adjust. If a tariff remains in place, affected importers may seek alternative suppliers, revise product prices or absorb part of the extra cost. If a government changes or removes a measure, the applicable border calculation may change too. These are possible business responses, not a guarantee that a particular product’s price will rise or fall by a specific amount.

For a specific shipment, confirm the product’s tariff classification, country of origin, customs value and any applicable trade-agreement treatment or surtax against current Canada Border Services Agency and Finance Canada guidance. For shoppers, a tariff announcement alone does not reveal the final shelf-price impact; that depends on how the supply chain responds.

Frequently asked questions

Is a tariff paid by the exporter?

Usually, the importer pays the duty to the importing country’s customs authority. The exporter may be affected indirectly if the importer negotiates prices or changes suppliers.

Does every imported product have a tariff?

No. Rates vary by product, origin and applicable trade rules, and some goods may enter duty-free. Check the current tariff schedule for the exact item.

Do tariffs automatically raise consumer prices?

No. They add a cost to covered imports, but businesses may absorb, share or pass on that cost. The effect on retail prices varies.
