Mount Lorne is situated in the traditional territories of two first nations:
The Carcross/Tagish First Nation (CTFN), a self-governing First Nation with its administrative centre located in the town of Carcross. The original inhabitants of this area are the Tagish people who belong to the Tagish linguistic grouping of the Athapaskan language family. The First Nation has built its governance structure based on the clan system; six Tlingit Clans are represented in the First Nation with each clan playing a vital role in the governance of the First Nation. Culture is alive and well with CTFN and the community is committed to their culture, to the practice of the Potlatch, and preserving the songs and dances of the clans.
The Kwanlin Dun First Nation is a self-governing First Nation with its administrative centre located in the town of Whitehorse: “We are the Citizens of the Kwanlin Dün First Nation living together in the Traditional Territory of the Kwanlin Dün First Nation. We acknowledge the Tagish Kwan as the original people who live and occupy the lands within the Traditional Territory, which lie at the headwaters of the Yukon River. For many generations, our people have lived along the Chu Nínkwän (today, the Yukon River). Linguistically, the Kwanlin Dün are affiliated with the Southern Tutchone Tribal Council. The Kwanlin Dün include people of Southern Tutchone, Tagish and Tlingit descent. A large part of the Kwanlin Dün citizens live in the Whitehorse area, with the balance dispersed throughout Canada, the U.S. (predominantly Alaska) and abroad.”
