CFMETR, Nanoose Bay

The Canadian Forces Maritime Experimental and Test Ranges (CFMETR) is a maritime test facility located on the east side of Vancouver Island, at Nanoose Bay.

The ranges operated by CFMETR are located over an area of the Strait of Georgia—known as Area "Whiskey Golf"—that is several hundred metres deep, several dozen kilometres long and several kilometres wide over a seabed composed of soft mud and free of underwater obstacles. The facility employs a 3-dimensional sonar tracking system for monitoring the performance and position of objects in these waters for real-time tracking.

Equipment tested at the facility consists of a variety of devices, including sonobuoys, sonar systems (ship and aircraft), torpedoes and the repair and overhaul of the dipping sonar used on Canada's Sea King helicopter fleet. No explosives are used.

This facility is unique in the Canadian Forces as it staffed by active military personnel from the Royal Canadian Navy (RCN) and DND civilian employees, as well as a small number of U.S. Navy civilian employees from Naval Base Kitsap. The facility is operationally controlled as a field unit of NDHQ. There is a joint funding agreement between the Canadian and United States Governments.

During the so-called Salmon War of 1997, then-BC Premier Glen Clark threatened to close the base by terminating the lease for use of the seabed, which is owned by the province and leased to the Canadian military. This brought quick rebuttal from Ottawa, saying that would expropriate if needed.
