Canada announces retaliatory tariffs after U.S. President Donald Trump’s administration imposes 50% tariffs on about $28 billion (roughly $20 billion) worth of Canadian goods. Ottawa says its counter-tariffs will be set “dollar for dollar” and “rate for rate” against the targeted U.S. measures, affecting hundreds of U.S. product categories. The Canadian response is scheduled to take effect September 8, with counter-tariff rates of 15%, 25%, or 50% depending on the product.

The Canadian government attributes the breakdown to last-minute changes during trade negotiations and says the U.S. proposal became “unfair” and “uneconomic.” Multiple outlets report Prime Minister Mark Carney suspends talks and pulls negotiators ahead of a deadline, citing concerns about the reliability of any agreement. The U.S. sides, as described in some coverage, place responsibility on Canada for failing to finalize terms earlier agreed.

Outlets also describe the affected sectors differently but broadly agree on key categories such as steel and aluminum and consumer and industrial goods. Several reports add that Ottawa pairs the tariff response with additional financial support for workers and businesses, and that the dispute follows a period of escalating tariffs across multiple areas, including autos and related inputs.
