Mayne Island Water Aerodrome, formerly IATA: YAV[2][3], TC LID: CAW7, is a defunct aerodrome that was located at Miners Bay adjacent to Mayne Island in British Columbia, Canada.

Although the aerodrome is no longer registered with Transport Canada and is classified as defunct it still has scheduled flights.

In this case defunct means that it no longer meets Transport Canada standards, not that the area is no longer in operation.

[1] The dock was constructed at an unspecified time in the 20th century.

It was built to harbor boats and serve as a communal fishing area.
