Canada counter-tariffs took effect on more than 700 United States products at 12:01 a.m. Eastern time on 8 September 2026. The duties run at 15, 25 or 50 per cent and cover C$27.6 billion of annual imports. Canadian importers pay them at the border, not American exporters.
What Took Effect on 8 September
The measure is a Canadian import duty applied on top of existing rates, and it applies only to goods that originate in the United States. As of 8 September 2026, it covers C$27.6 billion (about US$19.9 billion) of annual imports across more than 700 products, according to the Department of Finance Canada list published on 26 August 2026.
Origin is decided by where a good was made, not where it was shipped from. Canada applies the country-of-origin marking rules used under the Canada-United States-Mexico Agreement, the trade pact known in Canada as CUSMA and in the United States as USMCA.
Goods that were already in transit to Canada before 8 September are excluded. That carve-out is in the Finance Canada notice itself, and it means shipments that left a US port in late August clear at the old rate.
The Three Rate Bands, and What Sits in Each
Canada set three bands rather than one flat rate, and the band a product falls into is set by its tariff classification, not by its brand or its price.
| Rate | Examples of goods covered |
|---|---|
| 50 per cent | Steel products (ingots, bars, rods, wire, tubes, pipes, flat-rolled products, structures); dairy including milk powders, whey and casein; honey and molasses; beauty and personal care goods such as perfume, sunscreen, lip and eye make-up and hair products; plywood and veneered panels; chemical wood pulp; textiles and clothing; plastics; glass containers |
| 25 per cent | Certain cheeses; sawn coniferous softwood such as pine, fir and spruce; kraft and tissue paper, including toilet paper, facial tissue and napkins; carpets; some springs; steel household appliances, radiators and cookware |
| 15 per cent | Electronics and tools, including routers and network switching equipment for transmitting voice, images and data |
Because the bands follow tariff classifications rather than product names, two items that look similar on a shelf can land in different bands. Sawn softwood sits at 25 per cent while plywood made from the same species sits at 50 per cent.
Who Actually Pays Canada’s Counter-Tariffs
The Canadian importer of record pays, at the point the goods enter Canada. American exporters are not billed by the Canada Border Services Agency and send no cheque to Ottawa.
That is the part most headlines skip. A counter-tariff is a tax collected by the retaliating government from its own buyers. The pressure on the other country is indirect: US sellers lose Canadian orders when the duty makes their goods uncompetitive against Canadian or third-country supply.
How much of the duty reaches a shelf price depends on the importer, the contract and whether a non-US substitute exists. A Canadian buyer with an alternative supplier may absorb little; one with no substitute passes on more.
What the Tariffs Add to Canadian Household Costs
The only detailed public estimate so far comes from Trevor Tombe, a professor of economics at the University of Calgary and director of fiscal and economic policy at its School of Public Policy. In an analysis published in The Hub on 1 September 2026, he put the cost to Canadian consumers at about C$4 billion a year and the effect on overall consumer prices at roughly 0.25 per cent.
Tombe’s breakdown estimates about C$250 a year for families with children and under C$170 for families without. Those are averages across many households, not a figure any single family will see; what a household actually pays depends on how much of its spending goes to the goods on the list.
The estimate also finds the burden is uneven. Households earning under C$30,000 a year lose more than 0.5 per cent of disposable income, more than three times the share lost by households earning above C$150,000. Tombe describes the measure as a regressive tax, because lower-income households spend a larger share of their income on goods. This is one economist’s modelling, published on 1 September, and the Canadian government has not published a competing household estimate.
Why Canada Acted, and What the United States Did First
The counter-tariffs answer a US measure taken under Section 338 of the Tariff Act of 1930, a rarely used provision that allows the president to impose duties on countries found to discriminate against US commerce. President Donald Trump signed three proclamations invoking it on 20 July 2026: Proclamation 11046 covering alcoholic beverages, 11047 covering dairy and 11048 covering motor vehicles.
The resulting 50 per cent US tariff took effect at 12:01 a.m. Eastern time on 22 August 2026 and hit C$27.6 billion of Canadian goods. It applies even to shipments that would otherwise qualify for preferential CUSMA treatment, and it carries no statutory expiry date.
Talks collapsed the day before it landed. Prime Minister Mark Carney said the United States asked “too much” and “offered too little”, and told a press conference: “You’re at war when you get attacked. We got attacked.” He committed Canada to matching the US measure “dollar for dollar in order to protect Canadian workers, farmers, families, and businesses”.
The C$7.5 Billion Package for Affected Businesses
Alongside the counter-tariffs, the federal government announced C$7.5 billion in support on 25 August 2026, aimed mainly at small and medium-sized enterprises in the exposed sectors. The main components are:
- An extra C$1.5 billion for the Regional Tariff Response Initiative, delivered from September 2026 through Canada’s Regional Development Agencies. The cap on non-repayable grants rises from C$1 million to C$3 million, and qualifying businesses can access interest-free loans of up to C$2 million.
- C$500 million in liquidity support through the Business Development Bank of Canada’s Pivot to Grow programme.
- C$2 billion for a new Canada Strong Diversification Fund, set up as a stream of the Strategic Response Fund, for capital investment, operational changes and finding markets outside the United States.
Eligibility and application details sit with the Regional Development Agencies and the Business Development Bank rather than with Finance Canada, and terms differ by programme and by region.
What Is Still Unresolved
No further round of Canada-US talks had been scheduled as of 8 September 2026. Three things remain open:
- US auto tariffs: Al Jazeera reported in late August that Washington has proposed doubling existing tariffs on Canadian vehicles to 50 per cent from 1 January 2027. That has not taken effect, and Carney has said Canada would respond.
- Bombardier: Al Jazeera also reported that Trump threatened to block sales of Bombardier aircraft in the United States unless they are built there. No proclamation or order implementing that has been published.
- How long the measures last: The US Section 338 action has no expiry and can be modified, suspended or terminated by the president at any time. Canada’s counter-tariffs are framed as a match to it, which ties their removal to a negotiated outcome that does not yet exist.
Frequently Asked Questions
When Did Canada’s Counter-Tariffs Take Effect?
They took effect at 12:01 a.m. Eastern time on 8 September 2026. Goods already in transit to Canada before that moment are excluded.
Who Pays Canada’s Counter-Tariffs?
The Canadian importer of record pays the duty to the Canada Border Services Agency when the goods enter Canada. American exporters are not charged directly.
How Much Are the Counter-Tariffs?
There are three bands: 15, 25 and 50 per cent, depending on the product’s tariff classification. The 50 per cent band covers steel, dairy, personal care goods, plywood, textiles, clothing and plastics.
How Many US Products Are Covered?
More than 700 products, worth C$27.6 billion (about US$19.9 billion) of annual imports, according to the Department of Finance Canada list published on 26 August 2026.
Will This Raise Prices in Canada?
Economist Trevor Tombe estimated in The Hub on 1 September 2026 that the measures would raise overall Canadian consumer prices by about 0.25 per cent and cost consumers around C$4 billion a year. Actual price changes depend on the importer, the product and whether a non-US supplier is available.
Do the Counter-Tariffs Apply to Goods Shipped Through the United States?
No. They apply to goods that originate in the United States, determined by CUSMA country-of-origin marking rules, not by the country a shipment was despatched from.
