We're a member of Castle - Canada's premier buying group

Since 1963, builders, contractors and consumers have been relying on Castle as their building supply partner.  Whether you're looking for lumber, building materials, hardware or advice, hundreds of Castle dealers across Canada are trusted to deliver quality products and value.

Castle dealers are independent. They run their own stores and businesses. They know their communities, their customers, and their needs.  That's why Castle members are growing and succeeding across Canada - they live in the communities they serve. At Castle, we are your trusted building supply partner.

Specializing in residential renovation and new construction, Castle stores are the backbone of the retail lumber and building material industry. Today's current operators have grown up in their family business. First-hand knowledge of materials, construction techniques and local trade capability is found in every Castle operation. Castle managers and owners work the order desk, visit job sites, and manage material flow, and they bring a sincere passion for what they do.
