Prime Minister Mark Carney says Canada will impose retaliatory tariffs on U.S. goods beginning September 8, escalating trade tensions between the two North American neighbors.
The measures are intended to respond to U.S. tariffs affecting Canadian exports.
Canadian officials have not yet detailed the full list of products or the tariff rates that will apply.
The announcement gives businesses and consumers less than a month to prepare for possible changes in prices, supply chains, and cross-border trade.
The move could increase pressure on Washington and Ottawa to negotiate, while raising the risk of further countermeasures.
Canada and the United States share one of the world’s largest trading relationships, with billions of dollars in goods crossing their common border each day. Any prolonged dispute could affect manufacturers, farmers, retailers, and consumers in both countries.
The Canadian government is expected to provide additional details before the tariffs take effect.
