OTTAWA, ONTARIO / RankWire.AI / – Canada has revealed plans to impose tariffs of 15%, 25%, and 50% on C$27.6 billion worth of U.S. imports starting September 8, according to Prime Minister Mark Carney. These measures target over 700 tariff items and are calibrated to mirror U.S. duties on a one-to-one basis. The implementation date follows the enforcement of new U.S. tariffs on August 22, with Canada affirming that each product chosen will carry the same rate as the corresponding U.S. measure.

The scope of Canadian tariffs extends beyond metals and automobiles. Included in the list are household appliances, furniture, clothing, electronics, agricultural machinery, dairy products, pulp, and paper. Several steel and aluminum items are also subject to the highest tariff level. Prior to announcing this latest package, Canada had already applied counter tariffs on certain U.S. goods. Existing Canadian duties on U.S. automobiles will remain in effect alongside the new tariffs.
The 50% tariff rate applies to specific steel and aluminum products, along with some furniture and apparel. A 25% rate will be levied on certain appliances, dairy items, and metal derivatives. All other goods will face a 15% tariff, with rates aligned to U.S. duties on similar Canadian exports. The Government of Canada emphasized that the new list is focused on sectors directly impacted by U.S. trade actions.
Tariff list broadens across strategic sectors
Ottawa has also announced a new aid package totaling C$7.5 billion for workers and companies affected by the tariffs. This includes C$1.5 billion allocated for the Regional Tariff Response Initiative. Additionally, C$500 million will support business liquidity through the Business Development Bank of Canada’s Pivot to Grow program. Furthermore, C$2 billion has been designated for the Canada Strong Diversification Fund. Officials have reduced the minimum revenue threshold for certain support programs to C$1 million.
An extra C$3.5 billion will be directed toward workers and employers through employment, training, and retention schemes. These measures encompass temporary flexibilities in Employment Insurance and funding for workplace training programs. Finance Minister François-Philippe Champagne confirmed that the counter tariffs will correspond dollar-for-dollar and rate-for-rate with U.S. measures. The federal government’s package supplements existing support initiatives introduced during earlier rounds of U.S. tariffs, which Canada states provided nearly C$25 billion in aid.
Effective date for new duties is September 8
The tariffs will be applicable to goods classified as U.S. origin under Canadian rules for country of origin. Goods already in transit when the measures come into effect will not be subject to the new surtaxes. The duties will commence at 12:01 a.m. on September 8, with the Canada Border Services Agency overseeing the tariffs as products enter the country. Businesses are still able to apply for relief via Canada’s existing tariff remission process if they meet the relevant criteria.
The new measures expand the range of products involved in the Canada-U.S. trade dispute, now including industrial inputs, consumer goods, and agricultural commodities. Importers will face varying tariffs depending on each item’s classification. This September 8 package will operate alongside the counter tariffs retained by Canada on U.S. automobiles, collectively covering C$27.6 billion in U.S. imports and more than 700 tariff items listed.
