Canada has announced retaliatory tariffs on about US$20 billion worth of US goods, escalating the trade dispute between the two North American neighbours after negotiations between Ottawa and Washington broke down. The counter-tariffs will cover around 700 products and are scheduled to take effect on September 8, 2026.
The Canadian government said the measures will match the latest US tariffs dollar-for-dollar and rate-for-rate. The new duties will range from 15% to 50%, targeting products including steel, aluminium, dairy, appliances, agricultural equipment, furniture, clothing, pulp and paper, and electronics.
Canada Hits Back
Finance Minister François-Philippe Champagne announced the countermeasures after Canada suspended trade negotiations with the United States.
Ottawa said the decision followed what it described as unfavourable terms proposed by Washington. Canada said the retaliatory measures are intended to protect domestic workers, farmers, manufacturers and businesses affected by US tariffs.
The counter-tariffs will apply to goods worth approximately C$27.6 billion, or US$19.94 billion, based on annual US exports to Canada.
Tariffs Start September 8
The new Canadian duties will come into force at 12:01 AM on September 8.
Under the announced structure, some US products will face a 15% tariff, others 25%, while selected goods will face duties of 50%. The rates are designed to correspond to the latest US tariff rates imposed on Canadian products.
Canada's government has also clarified that the measures apply to goods originating in the United States and will not cover US goods already in transit to Canada when the tariffs take effect.
Steel, Dairy Targeted
The Canadian tariff list covers a wide range of products.
Steel and aluminium, furniture and clothing will face tariffs of up to 50%. Dairy products such as cheese, appliances, seafood and certain steel and aluminium derivatives will face 25% duties.
Electronics and tools are among products facing the lower 15% rate. Agricultural equipment, pulp and paper products and other manufactured goods are also included in the countermeasures.
The breadth of the measures means the dispute could affect manufacturers, retailers, consumers and supply chains in both countries.
US Tariffs Trigger Response
Canada's retaliation follows the US decision to impose 50% tariffs on about US$20 billion of Canadian imports, effective August 22.
The US measures followed the collapse of last-minute trade negotiations. Canadian Prime Minister Mark Carney had said Ottawa would respond if Washington proceeded with the new tariffs.
The latest developments have pushed relations between the two traditionally close trading partners to one of their most difficult points in decades.
Ottawa Announces Support
Alongside the tariffs, Canada announced a C$7.5 billion support package for businesses and workers affected by the trade dispute.
The measures include assistance for small and medium-sized businesses, financing support and programmes aimed at workers who could face economic disruption because of the tariffs.
Ottawa said the support measures are intended to give affected industries time to adjust while protecting employment and domestic production.
Trade War Risks Grow
The escalation comes despite the deep economic integration between Canada and the United States. The two countries exchange hundreds of billions of dollars in goods every year, with major links across energy, agriculture, manufacturing and consumer products.
Economists have warned that prolonged tit-for-tat tariffs could raise costs for businesses and consumers, disrupt supply chains and weaken investment confidence.
The impact could be particularly significant in industries that depend heavily on cross-border trade.
Trump Threatens More Tariffs
US President Donald Trump has continued to criticise Canada's trade position following the collapse of negotiations. He has also announced plans for additional 50% tariffs on Canadian automobiles and parts from January 1, 2027, adding another potential flashpoint to the dispute.
The latest escalation leaves both governments facing pressure to protect domestic industries while avoiding a wider economic confrontation.
With Canada's counter-tariffs not taking effect until September 8, there remains a window for further negotiations. However, the increasingly hostile rhetoric and additional tariff threats have raised concerns that the dispute could become a prolonged trade war.
