OTTAWA, ONTARIO / RankWire.AI / – Canada will implement tariffs of 15%, 25%, and 50% on C$27.6 billion worth of U.S. imports starting September 8, Prime Minister Mark Carney announced. These measures encompass more than 700 tariff items and align exactly with U.S. duties on a rate-for-rate basis. The date of enforcement was set after the U.S. imposed new tariffs on August 22. Canada confirmed that each selected product will carry the same duty rate as the corresponding U.S. measure.

The scope of Canadian tariffs extends far beyond metals and automobiles. The list includes household appliances, furniture, clothing, electronics, agricultural machinery, dairy products, pulp, and paper. Several steel and aluminum items will also be subject to the highest tariff rate. Prior to announcing this new package, Canada had already imposed retaliatory tariffs on some U.S. goods. Existing Canadian duties on U.S. automobiles will continue to be in effect alongside the new tariffs.
The 50% tariff category applies to selected steel and aluminum products, as well as certain furniture and apparel items. Canada will impose a 25% duty on some appliances, dairy products, and metal derivatives. Other commodities will face a 15% tariff according to the published schedule. Each rate matches the U.S. duties levied on comparable Canadian exports. The Government of Canada highlighted that the new list emphasizes sectors directly impacted by U.S. trade measures.
Tariff Expansion Targets Key Industry Sectors
Ottawa has also announced C$7.5 billion in additional and expanded support for workers and businesses affected by the tariffs. This package includes C$1.5 billion allocated for the Regional Tariff Response Initiative. An extra C$500 million will help sustain business liquidity through the Business Development Bank of Canada’s Pivot to Grow program. Additionally, the government designated C$2 billion for the Canada Strong Diversification Fund. Officials reduced the minimum revenue requirement for some support programs to C$1 million.
A further C$3.5 billion will aid workers and employers through employment, training, and retention initiatives. These measures include temporary flexibilities in Employment Insurance and funding for workplace training. Finance Minister François-Philippe Champagne stated that the counter tariffs will mirror U.S. measures dollar for dollar and rate for rate. This federal package complements support programs introduced during earlier U.S. tariff rounds, which Canada claims provided nearly C$25 billion in assistance.
Implementation of New Duties Starts on September 8
The tariffs will target goods classified as U.S. origin under Canadian rules. Products already in transit when the measures take effect will not be subject to the new duties. The duties will commence at 12:01 a.m. on September 8. The Canada Border Services Agency will oversee the collection as these products enter the country. Businesses can still apply for relief through Canada’s existing tariff remission process if they meet the necessary criteria.
These latest measures expand the scope of the Canada-U.S. trade dispute, covering industrial inputs, consumer goods, and agricultural products. Importers will face varying rates depending on each item’s tariff classification. The September 8 package will run concurrently with retained Canadian counter tariffs on U.S. automobiles. Collectively, the measures target C$27.6 billion worth of U.S. imports across more than 700 tariff items.
