A tariff is a tax one government places on goods imported from another country, used to raise costs for foreign producers and protect domestic industries from cheaper competition. Canada's Prime Minister Mark Carney told his country that Donald Trump's decision to escalate those taxes against Canada has produced something beyond a routine trade dispute. Canada, he said, is now at war with the United States.

Carney's framing was deliberate. He told Canadians that Trump "miscalculated" in pushing the tariff campaign further against Canada. That is a direct public judgment from a sitting head of government: an assessment of a decision Washington has already made, not a warning about what might happen next.

The word "war" carries weight because it is not a technical or legal term in trade policy. Carney chose it to communicate urgency to a domestic audience, to signal that Ottawa treats this as something more than a negotiating pressure campaign to outlast. His message to Canadians was that the escalation that got them here was Trump's mistake.
