OTTAWA, ONTARIO / RankWire.AI / – Canada has announced new tariffs of 15%, 25%, and 50% on C$27.6 billion worth of U.S. imports, effective from September 8, Prime Minister Mark Carney confirmed. The targeted measures include over 700 tariff categories and are aligned with U.S. duties on a one-to-one basis. The government set the effective date following the implementation of U.S. tariffs on August 22. Canada clarified that each specific product will bear the same tariff rate as the corresponding U.S. measure.

The scope of Canadian tariffs extends beyond metals and vehicles. Items such as household appliances, furniture, clothing, electronics, agricultural machinery, dairy products, pulp, and paper are also included in the list. Several steel and aluminum items will be subjected to the highest tariff rate. Prior to announcing this latest package, Canada had already enacted retaliatory tariffs on certain U.S. goods. The existing Canadian duties on U.S. automobiles will remain in place alongside the new tariffs.
The 50% tariff bracket applies to selected steel and aluminum products, as well as some furniture and apparel items. A 25% duty will be levied on certain appliances, dairy items, and metal-based products. Other commodities will face a 15% tariff as outlined in the official schedule. Each rate corresponds directly with the U.S. duty imposed on similar Canadian exports. According to Canadian authorities, the new list emphasizes sectors directly impacted by U.S. trade actions.
Tariff expansion impacts key industry sectors
Ottawa also unveiled C$7.5 billion in new and expanded support measures for workers and companies affected by the tariffs. This package includes C$1.5 billion allocated for the Regional Tariff Response Initiative. An additional C$500 million will bolster business liquidity via the Business Development Bank of Canada’s Pivot to Grow program. Furthermore, C$2 billion has been designated for the Canada Strong Diversification Fund. The government also lowered the revenue threshold for certain support initiatives to C$1 million.
An extra C$3.5 billion will go toward programs focused on employment, training, and retention efforts, including temporary flexibilities in Employment Insurance and funding for workplace skill development. Finance Minister François-Philippe Champagne stated that the counter tariffs will mirror the U.S. measures dollar for dollar and rate for rate. This federal aid package supplements existing support programs introduced during earlier U.S. tariff rounds, which have provided nearly C$25 billion in assistance so far.
Effective date and scope of new tariffs
The new tariffs will apply exclusively to goods classified as U.S. origin according to Canadian country-of-origin regulations. Items already in transit when the tariffs take effect will be exempt from the new duties. The tariffs will commence at 12:01 a.m. on September 8, with the Canada Border Services Agency overseeing their enforcement as products cross into Canada. Businesses are encouraged to apply for relief through the existing tariff remission procedures if they qualify.
These latest measures expand the scope of the Canada-U.S. trade dispute by including a broader array of products, notably industrial inputs, consumer goods, and agricultural items. Importers will encounter varying rates based on each item’s tariff classification. The September 8 tariff package will operate alongside the existing Canadian counter tariffs on U.S. automobiles. Overall, these actions involve C$27.6 billion in U.S. imports and encompass more than 700 tariff categories listed for duty application.
