Following a December 2007 governance referendum it became a neighborhood within what is now the District of West Kelowna. It has no legal borders since it is a neighborhood and opinions vary as to exactly where Westbank begins and ends. The District of West Kelowna has a total population, including Westbank, of about 30,892.
Some government powers have been given by treaty to the Westbank Nation.
