Flight attendants for Canada's largest carrier, Air Canada, will continue to strike despite a back-to-work order issued by the Canadian government, the Canadian Union of Public Employees (CUPE) said in a statement Sunday.

The union representing 10,000 Air Canada flight attendants said it will challenge an order to return to work and remain on strike.

Air Canada suspended plans to restart operations Sunday after the union representing 10,000 flight attendants said it will defy a return to work order.
