The Tsleil-Waututh Nation (Halkomelem: səlilwətaɬ IPA: [səlilwətaɬ]), formerly known as the Burrard Indian Band or Burrard Inlet Indian Band, is a First Nations band government in the Canadian province of British Columbia. The Tsleil-Waututh Nation ("TWN") are Coast Salish peoples who speak hən̓q̓əmin̓əm̓, the Downriver dialect of the Halkomelem language, and are closely related to but politically and culturally separate from the nearby nations of the Squamish and xʷməθkʷəy̓əm (Musqueam), with whose traditional territories some claims overlap. The TWN is a member government of the Naut'sa mawt Tribal Council, which includes other governments on the upper Sunshine Coast, southeastern Vancouver Island and the Tsawwassen band on the other side of the Vancouver metropolis from the Tsleil-waututh. There are almost 600 members with 287 living on the reserve as of January 2018. According to the 2011 national Community Well Being Index, Burrard Inlet 3 is considered the most prosperous First Nation community in Canada. From Wikipedia
