Historically, the Plateau people of Canada were divided into three main groups: the Athapascan, Interior Salish, and Ktunaxa. These three groups could then be further divided into the eight main Plateau groups: the Tsilhqot'in (formerly the Chilcotin), the Carrier, the Nicola, Secwepemc (formerly the Shuswap), the Stl'atl'imx (formerly the Lillooet), the Okanagan, the Nlaka'pamux (formerly the Thompson), and the Ktunaxa (formerly the Kutenai or Kootenay).
