Vancouver International Airport has three terminals: The domestic terminal, which was constructed in 1968 and recently given a top-to-bottom renovation; the International Terminal, which was newly constructed in the early 1990s, and the South Terminal, which is a portion of the original terminal that is still in use. The International and Domestic terminals can effectively be considered to be one building divided into two sections, while the South terminal is located in a remote part of the airport
