President Donald Trump announced a sweeping 50 percent tariff on a wide range of Canadian goods.
The administration plans to use an untested legal provision to enforce the measure.
These duties target major Canadian exports, including lumber, dairy, and automobiles.
The move reignites a trade clash with one of America’s largest trading partners.
The tariffs are set to take effect within 90 days.
Canadian officials have condemned the decision as unfair and retaliatory.
Business groups on both sides of the border warn of economic disruption.
The legal basis for the tariffs relies on a rarely invoked national security clause.
Experts question whether the provision will hold up in international trade courts.
The announcement comes amid ongoing tensions over trade imbalances and border policies.
