• Enhance co-operation between the Inuvialuit and the Government of Canada and the Government of the Northwest Territories in planning, operating and managing the park.
• Enhance and support local employment and business, and to strengthen the local and regional economies, while making provisions for subsistence usage within the park.
• Encourage greater understanding of and respect for the cultural heritage of the Inuvialuit and the natural environment in which it has evolved.
• Provide a setting in which long-term ecological and cultural heritage research may be undertaken.
• Maintain the ecological integrity of the park and thereby contribute to the maintenance of the ecological integrity of the Inuvialuit Settlement Area as a whole.
