The U.S. Supreme Court is soon expected to rule on the legality of President Donald Trump's sweeping worldwide tariffs. The court will rule on whether his use of a 1970s national security law violates the U.S. constitution, which clearly states that only Congress has the authority to implement taxes — of which tariffs are a type.

But regardless of which way the court rules, Trump and his administration have made it clear that tariffs will continue to be a central pillar of both their economic and foreign policy. And, just over a year after they were first announced, those tariffs have had perhaps no bigger impact than here in Canada. They've reshaped not just our economic relationship with our closest trading partner, but they've fractured the political relationship too.

Eric Miller, president of Rideau Potomac Strategy Group, explains what's at stake in the Supreme Court's ruling, and breaks down the impact of a year of Trump tariffs.
