More than 10,000 Air Canada flight attendants who went on strike early Saturday will be ordered to return to work by the Canada Industrial Relations Board (CIRB), according to a Saturday announcement by Canadian Jobs Minister Patty Hajdu.

Air Canada flight attendants will defy the back-to-work order and remain on strike after the federal government ordered binding arbitration to end the work stoppage, the Canadian Union of Public Employees told Radio-Canada on Sunday.

Air Canada said it planned to resume flights on Sunday after the Canadian Industrial Relations Board (CIRB) acted on a directive from Canada's Jobs Minister Patty Hajdu to end the strike resulting in the suspension of more than 700 flights.
