Groupe Aeroplan said Friday that the loyalty rewards program and Air Canada have reached an agreement with the Canadian Auto Workers union on the transition of call centre workers to Aeroplan.

Employees will transfer from the airline to Aeroplan as of June 1.

The deal was reached following mediation at the Canada Industrial Relations Board.

Terms of the agreement weren't immediately available.

The CAW represents 5,000 customer service and sales agents employed by Air Canada, including those handling calls for Aeroplan.
