As an Inuvialuit Board, Inuvialuit Game Council (IGC) plays a vital role in the co-management system. Under the IFA, the IGC represents the collective Inuvialuit interest in all matters pertaining to the management of wildlife and wildlife habitat in the ISR. This responsibility gives the IGC authority for matters related to harvesting rights, renewable resource management, and conservation.

The specific duties of the IGC are set out in Section 14(74) of the IFA. These duties include appointing Inuvialuit members for all Inuvialuit co-management bodies under the IFA and assisting these bodies whenever requested, advising government agencies, through the co-management bodies or otherwise, on renewable resource policy, legislation, regulation, and on any proposed Canadian position for international purposes that affects wildlife in the ISR. The IGC also allocates Inuvialuit quotas among the six ISR communities and appoints members for any co-management body dealing with Inuvialuit fish and wildlife harvesting and environment.

The IGC is comprised of a chair and two representatives appointed by Hunters and Trappers Committee (HTC) in each of the six ISR communities which are Aklavik, Inuvik, Ulukhaktok, Paulatuk, Sachs Harbour, and Tuktoyaktuk. The Chair can be from any of the six communities and is elected by all 42 HTC Directors.
