Canada has broken off trade negotiations with the United States and will apply matching tariffs on American goods from Tuesday 8 September, the office of Prime Minister Mark Carney said in a statement issued in Ottawa on 21 August. Canadian negotiators were instructed to return home.
The statement sets out the sequence plainly. The United States intends to apply a tariff of 50 per cent to a tranche of Canadian goods, effective at midnight on 21 August; Canada, it says, will match that measure dollar for dollar. A readout of a virtual First Ministers’ Meeting the following day confirmed the timing — the counter-tariffs come into force “the Tuesday after Labour Day,” which in 2026 falls on 8 September, giving importers a fortnight’s notice.
The value of the trade caught by the American measure is not yet settled between sources. The Prime Minister’s own statement puts it at approximately $28 billion of Canadian goods; several news organisations, among them Al Jazeera, reported a figure closer to $20 billion. The gap appears to be one of scope rather than dispute, and neither government has published a reconciling schedule. Ottawa has likewise not yet released the list of American products its own tariffs will cover; reporting has pointed to steel, electronics, dairy and agricultural equipment, and the government has said details will follow “in the coming days.”
What is already on the record is the fiscal shape of the response. Ottawa says it has provided close to $25 billion in support to affected workers and businesses over the past eighteen months, and has committed to further measures. Premiers and the Prime Minister also agreed to press on with removing internal trade barriers between the provinces and with diversifying export markets — the slower structural answer to a bilateral relationship that has now spent two years in tariff cycles.
“Canada will match those tariffs dollar for dollar to protect our workers and businesses,” the Prime Minister’s statement said.
For the two weeks until 8 September, the tariffs run in one direction only.
