The National organization comprises a federation of Member Societies located in major cities across Canada. Additionally, there are "Individual Members" located in areas at a distance from any Member Society or resident abroad.

The National Society is governed by an elected 12 member Board of Directors. The National Executive Committee consists of the President, Vice President/Secretary and Vice President/Treasurer and is voted in by secret ballot by the Board following the Annual General Meeting. Presidents of the Local Member Societies form the Presidents' Council which may raise issues and make recommendations to the Board from time to time.
