Canadian Prime Minister Mark Carney has announced retaliatory tariffs after US President Donald Trump imposed a 50 percent levy on about $20bn of Canadian goods, equal to 5.5 percent of Canada’s exports. Canada’s measures are scheduled to begin on September 8, with Ottawa expected to publish more details in the coming days.
The escalation threatens to raise business costs and consumer prices in both countries. Canadian industries including alcohol, dairy and furniture are expected to face significant pressure, while US businesses and households may also absorb higher prices.
Why negotiations broke down
Carney said talks collapsed late after the United States proposed terms he described as uneconomic and unfair. He said Washington sought to limit Canada’s ability to negotiate new trade deals, which he viewed as an infringement on Canadian sovereignty.
Carney also said US negotiators made unacceptable threats involving the French language and Quebec culture. He recalled Canadian negotiators from Washington, DC, saying the United States had asked too much while offering too little. Trump responded by saying Canada wanted the benefits of being a US state and again criticised Canadian tariffs on US farmers.

Which products are caught in the measures
The US levy covers more than 500 Canadian product categories, including beer, wine, liquor and cider; dairy products other than cheese; smartphones, cameras, radar equipment and antennae; hockey and other sports equipment; wood products; and seasonal goods such as toys, clothing, jewellery, makeup and perfumes.
Some products previously protected under the United States-Mexico-Canada Agreement are included. The new measures are also in addition to existing US tariffs on Canadian steel, lumber and cars. Canada says its response will target US steel, dairy, appliances, farm equipment, pulp and paper, and electronics.
What the tariff fight could mean for each economy
Trade expert Julian Karaguesian said the US measures could effectively price hundreds of Canadian goods out of the US market. The source report said small and medium-sized Canadian businesses could face higher costs, rising prices and increased bankruptcy risk, while alcohol, dairy and furniture were identified as especially exposed sectors.

The overall effect on Canada may be limited relative to the size of its economy because the affected goods represent about 5 percent of Canadian exports, according to trade specialist Steven Okun. But Canada remains highly dependent on the US: 73 percent of its exports were sold there last year, totalling $409bn, while the United Kingdom accounted for 6 percent and China for 4.4 percent in 2025 data cited in the source report.
US business leaders have warned that the tariffs could raise costs for American companies and families. Okun said previous tariff measures had raised prices and inflation rather than increasing US trade or investment, while Diamond Isinger, a former adviser to Justin Trudeau, said both countries would ultimately face economic pain from the escalation.
