About Castle


Castle is a member-owned and member-directed, not-for-profit buying group. 100% of profits and rebates are returned to members each year. Members are shareholders and receive annual audited financial statements. All members are treated equally, regardless of size or location.

Since our beginning in 1963, Castle's mission has been:
Strengthen the independent by maximizing each shareholder's profitability and growth.

Our values are:

Honesty     Transparency     Trust     Respect     Commitment

Castle's commitment to the independent is stronger now than ever. It's the reason Castle continues to be Canada's fastest growing lumber, building materials, hardware and commercial buying group.

Castle provides buying expertise for retail, commercial and specialty dealers from coast to coast.

RETAIL - Retailers serve the needs of local contractors, builders, government organizations, do-it-yourself and do-it-for-me consumers. Castle maximizes the retailer's buying power, making it easy for independents to do what they do best - serve their customers. Most retailers fly the Castle Building Centres banner, although the choice is theirs. Find a Castle Store Castle.ca.

COMMERCIAL - Commercial Builders Supplies Inc. (CBS) members are a select group of independent building supply distributors who dominate the markets they serve. They benefit from group buying power and CBS' ability to execute in gypsum, insulation, steel, millwork, roofing, lumber and panel board categories. Members serve the needs of commercial and residential developers, contractors, builders, installers, applicators, wholesalers and distributors. The CBS business model is compelling. Come take a look.

SPECIALTY - Castle retailers large and small, that are focused on a narrow range of products such as windows and doors, as well as bath and kitchen, may fly the Castle Specialty banner, although the choice is theirs.
