OTTAWA, ONTARIO / RankWire.AI / – Canada announced it 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 revealed. These tariffs will cover more than 700 items and are set to mirror U.S. duties exactly. The implementation date was determined following the enforcement of new U.S. tariffs on August 22. According to Canada, each product selected will carry the same rate as the equivalent U.S. measure.

The scope of Canadian tariffs extends well beyond metals and automobiles. Items on the list include household appliances, furniture, clothing, electronics, agricultural equipment, dairy products, pulp, and paper. Several steel and aluminum products will also be subject to the highest tariff rate. Prior to announcing this latest package, Canada had already imposed retaliatory tariffs on some U.S. goods. Additionally, existing Canadian duties on U.S. automobiles will remain in effect alongside the new tariffs.
The 50% duty rate applies to specific steel and aluminum products, along with certain furniture and clothing items. A 25% tariff will be levied on select appliances, dairy items, and metal-based products. Meanwhile, other goods will face a 15% tariff according to the published schedule. Each of these rates is aligned with the U.S. duties imposed on comparable Canadian exports. The Government of Canada stated that the new list emphasizes sectors directly impacted by U.S. trade measures.
Expansion of Tariff List in Key Sectors
Ottawa also unveiled C$7.5 billion in new and expanded aid targeted at workers and businesses affected by the tariffs. This package includes C$1.5 billion allocated for the Regional Tariff Response Initiative. An additional C$500 million will be used to enhance business liquidity through the Business Development Bank of Canada’s Pivot to Grow program. The government also assigned C$2 billion to the Canada Strong Diversification Fund. Furthermore, officials lowered the minimum revenue threshold for some support programs to C$1 million.
Another C$3.5 billion will be directed towards supporting workers and employers through employment, training, and retention initiatives. These include temporary flexibilities in Employment Insurance and funding for workplace training. Finance Minister François-Philippe Champagne noted that the counter tariffs will be matched dollar for dollar and rate for rate with U.S. measures. This federal aid package complements earlier support programs introduced during previous U.S. tariff rounds, which the government claims provided nearly C$25 billion in assistance.
Effective Date of New Tariffs is September 8
The tariffs will apply to goods classified as U.S. origin under Canadian country-of-origin rules. Items already in transit when the measures come into effect will be exempt from the new tariffs. The duties will commence at 12:01 a.m. on September 8. The Canada Border Services Agency will oversee the collection of tariffs as products cross the border. Companies may still seek relief via Canada’s existing tariff remission process if they meet the necessary criteria.
These latest measures expand the range of products involved in the Canada-U.S. trade dispute. They now include industrial inputs, consumer goods, and agricultural products. Importers will face varying rates depending on each item’s tariff classification. The September 8 tariffs will run concurrently with the remaining Canadian counter tariffs on U.S. automobiles. Together, these measures impact C$27.6 billion worth of U.S. imports across more than 700 tariff items.
