The Canadian cruiser HMCS Ontario passes through the locks of the Panama Canal, likely during a 1950s training cruise.

Ontario and other vessels helped train personnel for the Royal Canadian Navy (RCN) during the post-war expansion prompted by increasing Cold War tensions. Entering service with the RCN at the end of the Second World War, Ontario had arrived in the Pacific just as Japan surrendered. After refitting in Esquimalt, British Columbia, the cruiser spent much of its time as a training vessel until it was decommissioned in 1959.
