US President Donald Trump declared a 50 per cent tariff on the majority of Canadian imports, accusing the neighbouring country of unfair trading practices in key sectors such as motor vehicles, alcoholic drinks, and dairy produce.
The sudden decision threatens to deepen economic friction between the two long-standing North American allies. Industry analysts warn the policy could push consumer prices higher and place severe strain on cross-border commercial links.
A senior US administration official explained that Canada was targeted because it was among a small group of nations, including China, that chose to hit back with retaliatory duties against earlier American trade measures.
Official documentation from the White House confirms that President Donald Trump signed three separate proclamations under Section 338 of the US Trade Act of 1930 to enact the import taxes.
The administration stated that the 50 per cent levies will hit most Canadian products. This includes goods that previously moved duty-free across the border under the terms of the United States-Mexico-Canada Agreement.
Crucially for energy markets, the White House confirmed that the new taxes will not apply to crude oil and energy supplies, potash, seafood, or critical minerals.
Washington did not extend the United States-Mexico-Canada Agreement, which originally came into force in 2020. That decision led to new bilateral negotiations that could theoretically last until 2036.
The White House added that the new import taxes will take effect in 30 days. This buffer period leaves a narrow window for diplomatic talks before customs officials begin collecting the duties at border crossings.
Responding to the development, Canadian Prime Minister Mark Carney reaffirmed his country's commitment to open and fair commercial relations. He added that Ottawa remains fully prepared to engage in constructive talks with Washington.
In an official statement, Prime Minister Mark Carney pointed out that Canada has secured more than 20 new trade and security agreements globally. He expressed hope that calm dialogue could resolve the current disagreements with the United States.
He also cautioned that the ongoing trade dispute has already raised living costs for everyday families, particularly inside the United States, concluding that both nations would benefit far more from a negotiated deal.
