Canadian Forces Station Gloucester was a wireless HFDF intercept station near Ottawa, Ontario.
The site opened as Number 1 Station HMCS Bytown (1943), with name changes to HMC NRS Gloucester (1950), HMCS Gloucester (1950), and finally CFS Gloucester (1966) till the closure in 1972.[1][2]
One role of the station during the war years was the radio location of German U-boats in the North Atlantic. Until the Unification of the Canadian Armed Forces in 1968, the unit often provided ceremonial platoons at public events in Ottawa while representing the RCN.[3]
