Air Canada pilots have failed to negotiate a new agreement with the airline.
"To say we are disappointed would be a vast understatement," Jean-Marc Belanger, a spokesman for the Air Canada Pilots Association, said in a statement issued Saturday night. "We did everything possible to reach an agreement, paring down our proposals, addressing the airline's issues and showing flexibility at the bargaining table."
The ACPA did not say why the agreement could not be reached.
The pilots will now prepare a final offer for submission to federal arbitrator Doug Stanley, in compliance with the 90-day process legislated by the federal government.
The Air Canada Pilots Association represents 3,000 pilots.
