For 2025, the cost for a complete “turnkey” retail store (including foundation, insulation, interior fit-out, and labor) typically ranges between $180 and $350 CAD per square foot. If you are looking strictly at the steel shell “kit” price, that usually costs $25 to $40 CAD per square foot.
Keep in mind that location drives these costs. A simple strip mall build in rural Saskatchewan will be on the lower end, while a complex retail design in Vancouver or the GTA will push the higher end due to labour rates and stricter zoning requirements.
