The Supreme Court of Canada ruled Friday that Wal-Mart Canada Corp. was within its rights when it shut down a store in Jonquière, Que., that had been unionized seven months earlier... In September 2004, the United Food and Commercial Workers Union, Local 503, was certified to represent employees of the Wal-Mart store in Jonquière. However, attempts to reach a collective agreement failed. On Feb, 9, 2005, the contract issue was sent to arbitration, but that same day, Wal-Mart told the workers it was closing the store. The store eventually closed on April 29, 2005, putting approximately 190 employees out of work... [Chief Justice Ian] Binnie wrote, "The Jonquière store is closed and there is no possibility of reinstatement of the employees."... Louis Bolduc of the United Food and Commercial Workers Union also said the top court's decision opened a door because a labour board will now be able to investigate the reasons for store closures. "If we can prove the reasons are anti-union then we can sue for damages," he said
