Canada’s retaliatory tariffs on a range of U.S. goods took effect Friday, escalating a trade dispute between the two North American neighbors. The tariffs, announced in response to U.S. duties on Canadian steel and aluminum, target a variety of American products, including steel, aluminum, and consumer goods.

The move by Ottawa marks a significant development in the ongoing trade friction that has strained bilateral economic relations. The U.S. had previously imposed a 25% tariff on imported steel and a 10% tariff on imported aluminum from Canada, citing national security concerns. Canada has maintained that these U.S. tariffs are unjustified and have harmed its own industries.

In response, Canada’s measures include tariffs on specific U.S. agricultural products, manufactured goods, and construction materials. The Canadian government stated that the tariffs are designed to offset the negative impact of the U.S. duties on Canadian workers and businesses. The specific list of affected goods and their tariff rates were detailed by Canadian officials prior to the implementation.
