The Canadian Auto Workers union's' airline division said on Friday that it had not discussed job cuts announced by Air Canada on Thursday.

Canadian media reported on Friday that Joshua Koshy, the airline's chief financial officer, said in an investors' conference call that Air Canada would cut jobs among check-in agents and back-office employees by using new reservations technology. He did not say how many people would be affected.

"We have not had any discussions with Air Canada regarding any additional job cuts to our members," Leslie Dias, president of CAW Local 2002 Airline Division, said in a statement.

Air Canada's stock was down 38 Canadian cents, or 2.2 percent, at C$17.17 by early afternoon the Toronto Stock Exchange.
