Air Canada’s fleet remains grounded after flight attendants, represented by the Canadian Union of Public Employees (CUPE), defied a government-backed order to return to work. The airline has postponed plans to restart operations, describing the union’s defiance as illegal. The dispute, which has affected over 700 daily flights, stems from negotiations on wages and unpaid work. CUPE has called the government’s order unconstitutional, while the airline and government officials have stated the action is necessary to maintain industrial peace and protect the economy.
