Three Generations Selling Industrial Supplies & Fasteners Convoy-Westcan is proudly family-owned and located in Winnipeg, Manitoba. We were founded back in 1977 by our grandparents and father who started from their basement. The business is now operated by sons Craig and Andrew Polos alongside their parents Terry and Mandy Polos. We outgrew the basement and have a large warehouse and storefront to stock a huge inventory. We offer quality abrasives, fasteners, tools, safety products and now 3D printers to commercial, manufacturing, and retail customers.
