The Sooke Region Museum is operated by the Sooke Region Historical Society, a non-profit society incorporated under B C's Societies Act in 1975, and recognized as a Registered Charity by Revenue Canada. The Society's Annual General Meeting is held in late January, including election of eleven members to the Board of Directors. Annual memberships are $10.00, and Life Memberships can be purchased for $100.00.

Additional to the elected Directors, three delegates are appointed to sit on the Board, making a total of 14 Board Members. The appointees include a representative from the District Municipality of Sooke, an appointee from the Juan de Fuca Electoral Area of the CRD, and an appointee from the T'Sou-ke First Nation. Tax revenue from a Specified Area established in 1987, provides partial operating assistance to the museum.

The Sooke Region Historical Society sends out newsletters in June and December each year, in an attempt to keep members and supporters up to date on museum happenings.
