Warrant officer (WO) is a rank or category of ranks in the armed forces of many countries. Depending on the country, service, or historical context, warrant officers are sometimes classified as the most junior of the commissioned officer ranks, the most senior of the non-commissioned officer (NCO) ranks, or in a separate category of their own. Warrant officer ranks are especially prominent in the militaries of Commonwealth nations and the United States.
A non-commissioned officer (NCO) is a military officer who has not pursued a commission. Non-commissioned officers usually earn their position of authority by promotion through the enlisted ranks. In contrast, commissioned officers usually enter directly from a military academy, officer training corps (OTC) or reserve officer training corps (ROTC), or officer candidate school (OCS) or officer training school (OTS), after receiving a post-secondary degree.
The Canadian Armed Forces are the unified military forces of Canada, including sea, land, and air elements referred to as the Royal Canadian Navy, Canadian Army, and Royal Canadian Air Force.
The Royal Canadian Navy is the naval force of Canada. The RCN is one of three environmental commands within the Canadian Armed Forces. As of 2021, the RCN operates 12 frigates, four attack submarines, 12 coastal defence vessels, eight patrol class training vessels, two offshore patrol vessels, and several auxiliary vessels. The RCN consists of 8,570 Regular Force and 4,111 Primary Reserve sailors, supported by 3,800 civilians. Vice-Admiral Angus Topshee is the current commander of the Royal Canadian Navy and chief of the Naval Staff.
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.
Chief warrant officer is a senior warrant officer rank, used in many countries.
Leading seaman is a junior non-commissioned rank or rate in navies, particularly those of the Commonwealth. When it is used by NATO nations, leading seaman has the rank code of OR-4. It is often equivalent to the army and air force rank of corporal and some navies use corporal rather than leading seaman.
Before Unification as the Canadian Armed Forces in 1968, the Canadian military had three distinct services: the Royal Canadian Navy, the Royal Canadian Air Force, and the Canadian Army. All three services had a Regular (full-time) component and a reserve (part-time) component. The rank structure for these services were based on the services of the British military, the Royal Navy, the Royal Air Force, and the British Army. The change to a "Canadian" rank structure meant that many of the traditional (British) rank titles and insignia were removed or changed.

Admiral Percy Walker Nelles, was a flag officer in the Royal Canadian Navy (RCN) and the Chief of the Naval Staff from 1 January 1934 to 15 January 1944. He oversaw the massive wartime expansion of the RCN and the transformation of Canada into a major player in the Battle of the Atlantic. During his tenure U-boats raided the Gulf of St. Lawrence, Canadian Northwest Atlantic command was created, and the RCN provided up to 40% of all escort forces in the North Atlantic. His handling of the RCN's war effort had its opponents however, and he was removed from his post as Chief of the Naval Staff in January 1944. He was sent to London as Overseas Naval Attaché, coordinating RCN operations for Operation Overlord. He retired in January 1945 as a full admiral.
