On February 14, 2022, Prime Minister Justin Trudeau made what might be the most controversial decision of his tenure, invoking the Emergencies Act to end a three-week occupation of downtown Ottawa by truckers protesting mandatory COVID-19 vaccine mandates. Proclaimed in 1988, the Emergencies Act is designed to give federal officials extraordinary powers in the event of threats to Canada’s national security that can’t be managed under existing laws. Trudeau used it to make the protest illegal, freeze the accounts and cancel the vehicle insurance of participants, requisition tow trucks to clear protestors from the streets, among other measures. The government defended the first-ever invocation of the act as just and necessary; several premiers and the Canadian Civil Liberties Association called it an assault on democratic rights and civil liberties. As required by the act, Trudeau appointed a commission of inquiry into its use. Last November, Justice Paul Rouleau held six weeks of riveting hearings that included testimony by so-called Freedom Convoy organizers, police officials, cabinet ministers, and Trudeau himself.
