The Tsawwassen Legislature is the highest body of the Tsawwassen Government. It consists of 13 Tsawwassen Members, elected at a general election, plus the Chief, for a total of 14 Members. The duties of the Legislature are to discuss and make laws, which form the fundamental organizing principles and expressions of Tsawwassen Government. As part of that function the Legislature passes an annual budget, which is a key part of the accountability structure of Tsawwassen Government.

Each session lasts approximately 2 months; the number of meetings during each session varies, depending on the number and complexity of the bills and/or resolutions that are before the legislature during a given session.
