Gesgapegiag is one of two First Nations reserves on the south shore of the Gaspésie, most of whom are of Mi'kmaq ancestry. Most of the members reside on the federal Indian reserve that was set aside by the legislature of Lower Canada in 1853, for the exclusive use of the majority of Mi'kmaq in this region. The remaining Mi'kmaq live off-reserve in the eastern United States and across Canada, but stay connected to the community through modern communications and travel to. All community members, regardless of residence, participate in democratic elections held every two years to elect one Chief and twelve Councillors in accordance with Canada's Indian Act Election Regulations. The community is also allied to other Mi'kmaq communities in the Gaspé region of Quebec and in northern New Brunswick.
