The Supreme Court just agreed to hear Ottawa's appeal on the 2022 Emergencies Act. Four years later, the legal reckoning isn't over.

The federal government invoked the Emergencies Act for the first time in Canadian history on Feb. 14, 2022, giving itself sweeping temporary powers during the convoy protests that had gridlocked downtown Ottawa for roughly three weeks and snarled key border crossings.

The Canadian Press reported Thursday that the Supreme Court of Canada will hear Ottawa's appeal of the court rulings that it lacked sound statutory grounds to do so.

The invocation let the government regulate or prohibit public assemblies, designate protected places, direct banks to freeze assets, and ban support for protest participants, the Canadian Press reported. Many demonstrators had gathered against COVID-19 health restrictions, though others brought a broader set of grievances against the Trudeau government.

The Canadian Civil Liberties Association and other challengers convinced the Federal Court that the government had not met the legal threshold for emergency powers; a three-judge panel of the Federal Court of Appeal unanimously upheld that ruling in January, according to the Canadian Press.

Now the government takes the same argument to the country's highest court. The stakes go beyond relitigating 2022: a Supreme Court ruling would set the binding legal test for when a federal government can reach for emergency powers in any future crisis.

The road to the top court

The protest encampment in Ottawa lasted nearly a month before police cleared it in a series of February 2022 operations. The Federal Court's 2024 ruling that the invocation lacked statutory grounds was a major rebuke; the government's loss on appeal in January left the Supreme Court as its last option.

What a ruling could change

If the Supreme Court sides with Ottawa, the government gets its emergency playbook back with the country's highest authority behind it. If it loses, future governments would need to clear a higher legal bar before invoking the Act — a constraint that would shape every crisis response for decades.
