Arrowhead Development Corporation (ADC) was established to develop business concepts and incorporate businesses under a development corporation. ADC is governed by the Board of Directors and a Chief Executive Officer. The ADC manages band owned businesses on its three reserves; Long Plain Reserve No. 6, Keeshkeemaquah Reserve (Portage la Prairie), and Long Plain Madison Indian Reserve (Winnipeg).
In April 2015 the Arrowhead Development Corporation (ADC) was restructured to include the Community Economic Development Program (INAC), Community Development Program (MB Hydro) and Special Projects to its management. Chief Executive Officer was appointed who hired Human Resources Officer, two Special Projects Officers and a Controller.
Indigenous & Northern Affairs Canada provides annual funding to administer the Community Economic Development Program on the Long Plain Reserve. The First Nation (LPFN) and Arrowhead Development Corporation contribute to a majority of funds towards the LPFN economic development program and projects.
