The Canadian Navy's three Ville class tugs based in Halifax, Granville, Listerville and Merrickville have now put in 50 years of service and are still going strong. Built in 1974 by Georgetown Shipyard in Prince Edward Island, they are 365 bhp Cat powered with a single screw in a nozzle. At 45 feet long they are of a very convenient size for working in the confines of the HMC Dockyard. They also can be seen at other Navy installations in the harbour, most often in ship handling with the larger Glen class tugs. They also perform regular security patrols and other odd jobs such as fender placement.

As non-commissioned auxiliary vessels working under the direction of the Master Attendant in the King's Harbour Master's office, they are civilian crewed, but carry the usual naval pennant designation YTL (Yard Tug Little). They are referred to as CNAV, Canadian Naval Auxiliary Vessels.

They are so well maintained that there is no hint of their age. However at only a modest 7.5 tons bollard pull they may be under powered for the Navy's newer and much larger ships which are in the works. As craft that work only within the confines of the harbour, and for short trips, there would be an opportunity for electric / battery powered craft.
The Navy's slightly newer Glen class tugs, built in 1976, are being replaced, but I have not heard of replacement plans for the Villes, familiarly called "pups". They in turn replaced a series of earlier 45 foot "Pups", also with "Ville" names, that were built during World War II.
The war-built Merrickville served civilian owners for several more years after Navy duty.
The current Villes are heavily fendered below the waterline for work with submarines.

The recent visit to Halifax of the French submarine FS Tourville (coincidentally) saw a pair of our Villes in close attendance.
