(January 20, 2005) - TORONTO (Dow Jones/AP) - A second Canadian Wal-Mart has been unionized. A store in Quebec received union certification after a majority of the store's employees signed cards indicating the Canadian arm of the United Food and Commercial Workers Union was their official agent for collective bargaining. The union and Wal-Mart Canada, a unit of Bentonville-based retailing giant Wal-Mart Stores, already are negotiating a contract for another store in Jonquiere, Quebec. That store, which Wal-Mart revealed hasn't been profitable since it opened a few years ago, was automatically certified in August. Wal-Mart Canada spokesman Andrew Pelletier said the company is reviewing all its options, including a legal challenge to the decision by the Quebec Labour Relations Commission that certified the union.
