Canada Bread says it plans to shut down its Calgary bakery in September, putting approximately 63 employees out of work.
Spokeswoman Sylvia Sicuso said the closure comes after the bakery had seen orders falling over the past three years and is now running at less than 50 per cent of capacity.
The company said staff would receive severance packages, help with finding other jobs, and are encouraged to apply for work at other Canada Break operations.
Canada Bread said it planned to continue to supply bread to the Western Canadian market from its operations in Langley, B.C., Edmonton and Winnipeg.
Mexico-based Grupo Bimbo, one of the world's largest baking companies with operations in 22 countries, bought Canada Bread in 2014.
The company sells bread under brands including Dempster's, Villaggio, Bon Matin and Vachon.
