The CMM Membership program assists band members with applications for registration and membership. The CMM membership clerk issues Indian Status cards within the policy and guidelines set out by the Department of Indian Affairs. All status Indians are registered through the Indian Registry. This confidential database holds information pertaining to births, marriages, divorces, transfers, name changes and deaths.

Confirmation of Indian Status is often requested for gas tax exemption, access to health benefits and distribution of band funds resulting from claims settlements or other communal revenues.

Band lists compiled by the Membership Program are used to determine voting eligibility for community leadership elections. The Membership unit is also responsible for administering community leadership elections and referendums.

Membership lists also form the basis for per-capita community funding agreements.
