In 1986 pursuant to the Tripartite Master Agreement, the Province of Manitoba mandated Anishinaabe Pimadiziwin Inc. Thus, Anishinaabe Pimadiziwin Inc was officially recognized with duties and powers to deliver child and family services pursuant to the Child & Family Services Act in Manitoba.

Anishinaabe Pimadiziwin Inc. evolved from the signing of the Canada - Manitoba Indian Child Welfare Agreement in February 1982 and Subsidiary Agreement of August 1982.

Anishinaabe Pimadiziwin Inc was created as a the result of an agreement between the Government of Canada, the Province of Manitoba and the Brotherhood of Indian Nations to facilitate increased Band participation and responsibility in the provision of child and family service and also to prove a framework for the establishment of guiding principles and funding for the fulfillment of such responsibilities.

The original composition of Anishinaabe Pimadiziwin Inc consisted of eight (8) Nations: JACKHEAD, FISHER RIVER, PEGUIS, DAUPHIN RIVER, FAIRFORD, LAKE ST.MARTIN, LITTLE SASKATCHEWAN and LAKE MANITOBA. DAKOTA TIPI was later included by Order of Council.

In 1987, the nine (9) Nations decided to become two entities: Anishinaabe East Side and Anishinaabe West Side. The West Side comprised of DAUPHIN RIVER, FAIRFORD, LAKE ST.MARTIN, LITTLE SASKATCHEWAN and LAKE MANITOBA.

Today, these five (5) Nations continue to carry the original Anishinaabe Pimadiziwin Incs mandate as the other original Nations have formed their own agencies.
