Last month, the Navy bid farewell to the HMCS Protecteur at a ceremony at CFB Esquimalt in British Columbia.
The event marked almost 46 years of military service for the Canadian navy supply ship, including the Cold War, Gulf War and hurricane relief.
Protecteur retired after a devastating engine-room fire in 2014, which left the ship burning, powerless and adrift off Hawaii for 11 hours. It was towed to Pearl Harbor, then towed back to its home port of Esquimalt, B.C.
The supply ship was slated for replacement in 2019.
