Two ships of the Canadian navy have been named HMCS St. Croix.
The history of the Royal Canadian Navy goes back to 1910, when the naval force was created as the Naval Service of Canada and renamed a year later by King George V. The Royal Canadian Navy (RCN) is one of the three environmental commands of the Canadian Forces. Over the course of its history, the RCN has played a role in the First World War, contributed significantly to the Battle of the Atlantic during the Second World War, and was a part of NATO's force buildup during the Cold War. In 1968, the RCN was amalgamated with the Canadian Army and the Royal Canadian Air Force to form what is today the unified Canadian Armed Forces. The naval force was known as Maritime Command until 2011, when the environmental command was renamed as the Royal Canadian Navy.
