Castle is a Canadian building supplier and hardware partner. Since our beginning as a lumber and building materials buying group in Ontario in 1963, Castle has been committed to the independent LBM dealer. Our commitment has always been to help make our members successful.

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

Since 1963, the construction, do-it-yourself and retail industries have changed. Yet, Castle's commitment to the independent is stronger than ever. It's evident in the success of our retailers in every province across Canada. Our membership numbers continue to grow as does our reputation with contractors and consumers.
