Potash Corp. is temporarily laying off workers at mines in Saskatchewan and New Brunswick because of a slump in demand. The Saskatoon-based company says the Allan mine in Saskatchewan won't operate between Dec. 16 and Feb. 9. The mine in Sussex, N.B., is also shutting down for eight weeks between Dec. 30 and Feb. 23. Potash Corp. said in October it will shut its Lanigan and Rocanville mines in Saskatchewan for eight weeks starting Nov. 18 and Dec. 7, respectively.
