Canada Hits Back With Tariffs on US Goods Worth $20 Billion as Trade War Escalates

Canada has announced retaliatory tariffs on about C$27.6 billion (US$19.94 billion) worth of goods imported from the United States, escalating an increasingly bitter trade dispute between the two North American neighbours.

The Canadian government said on Tuesday that the counter-tariffs will take effect on September 8 and will match the new US duties dollar-for-dollar and rate-for-rate. The measures will impose tariffs of 15%, 25% and 50% on a range of American products.

The move follows the United States’ decision to impose a 50% tariff on C$27.6 billion of Canadian goods from August 22. Washington has justified the measures as a response to what it considers discriminatory Canadian trade practices.

Canada’s countermeasures will affect around 700 US products, including steel and aluminium, appliances, furniture, clothing, seafood, electronics, agricultural equipment, pulp and paper products and other manufactured goods.

Canadian Finance Minister François-Philippe Champagne said the government had negotiated with Washington in an effort to reach a comprehensive trade agreement but rejected what Ottawa considered unacceptable new US demands.

Canada’s government said its objective is to protect Canadian workers, businesses and strategic industries while avoiding unnecessary harm to Canadian consumers and companies. Ottawa has also announced a C$7.5 billion support package for businesses and workers affected by the US tariffs.

Prime Minister Mark Carney has taken a tougher stance toward Washington following the collapse of recent trade negotiations.

The latest escalation comes after US President Donald Trump threatened to impose additional tariffs of up to 50% on Canadian vehicles, trucks, auto parts and steel from January 1, 2027. The threats have raised fears that the dispute could spread to some of the most deeply integrated parts of the North American economy.

The United States and Canada have long maintained one of the world’s largest bilateral trading relationships, with supply chains in industries such as automobiles, energy, agriculture and manufacturing heavily integrated across their shared border.

The new tariffs therefore threaten to increase costs for companies on both sides and potentially feed into higher prices for consumers.

The latest measures mark another significant deterioration in relations between Ottawa and Washington.

Canada has pledged to diversify its trade relationships and reduce its reliance on the United States if the dispute continues, while US officials have indicated that further tariffs remain possible.

For now, Canada’s counter-tariffs are scheduled to begin on September 8, leaving both governments with a short window to resume negotiations and prevent the dispute from widening further.

The escalating confrontation has already raised concerns among businesses and investors about the future of North American supply chains and the economic consequences of a prolonged trade war.
