Royal Canadian Navy

The Royal Canadian Navy (RCN; , MRC) is the naval force of Canada, and one of three environmental commands of the Canadian Armed Forces. The command's official strength includes 8,400 Regular Force sailors, 4,100 naval reservists, and a fleet that includes 25 commissioned warships and additional auxillary vessels.

The RCN is headquartered in Ottawa, with its commander reporting to the Chief of Defence Staff. Three formations are responsible to the commander of the RCN: Maritime Forces Atlantic, based at CFB Halifax on the Atlantic coast; Maritime Forces Pacific, based at CFB Esquimalt on the Pacific coast; and the Naval Reserve, headquartered in Quebec City with 24 reserve divisions located across the country.

Established in 1910 as the Naval Service of Canada, the service received royal sanction in 1911 and was renamed the Royal Canadian Navy. In 1968, the RCN was unified with the Canadian Army and the Royal Canadian Air Force to form the Canadian Armed Forces (CAF), the RCN becoming its naval command, Maritime Command. The historic Royal Canadian Navy designation was restored in 2011. The RCN took part in several conflicts including the First World War, Second World War, the Korean War, the Gulf War, the War in Afghanistan, and other NATO and UN peacekeeping missions.

History

1910–1968

Established following the introduction of the Naval Service Act by Prime Minister Sir Wilfrid Laurier, the Naval Service of Canada (NSC) was intended as a distinct naval force for Canada that could, should the need arise, be placed under British control. The bill received Royal Assent on 4 May 1910. Initially equipped with two former Royal Navy vessels, HMCS Niobe and HMCS Rainbow, King George V granted permission for the service to be known as the Royal Canadian Navy on 29 August 1911.

World Wars

During the first years of the First World War, the RCN's six-vessel naval force patrolled both the North American west and east coasts to deter the German naval threat, with a seventh ship, HMCS Shearwater, joining the force in 1915. Just before the end of the war in 1918, the Royal Canadian Naval Air Service was established with the purpose of carrying out anti-submarine operations; however, it was disbanded after the armistice of 11 November.

After the war, the RCN took over certain responsibilities of the Department of Transport's Marine Service and slowly started to build its fleet, with the first warships specifically designed for the RCN being commissioned in 1932. At the outbreak of the Second World War, the Navy had 11 combat vessels, 145 officers and 1,674 men. During the Second World War, the RCN expanded significantly, ultimately gaining responsibility for the entire Northwest Atlantic theatre of war. During the Battle of the Atlantic, the RCN sank 31 U-boats and sank or captured 42 enemy surface vessels, while completing 25,343 merchant crossings. The navy suffered the loss of 33 ships and 1,797 sailors. To gain experience with the operation of aircraft carriers, RCN personnel crewed two British Royal Navy escort carriers from 1944 to 1946: , and .

Starting in May 1944, when Canada began drafting plans to assume a larger role in the Pacific Theatre after achieving victory in Europe, the Canadian government recognized that the RCN would require much larger vessels. In November 1956, HMCS Magnificent was chosen to transport men and supplies to Egypt as part of Canada's response to the Suez Crisis. In preparation for use as a transport, the ship's weapons were stripped, and her complement was reduced to 600 personnel. The initial plan was to embark the Queen's Own Rifles of Canada, but that order was rescinded in December.

1968–present

From 1964 through 1968, under Prime Minister Lester B. Pearson, the RCN, Royal Canadian Air Force and Canadian Army were amalgamated to form the Canadian Armed Forces. This process was overseen by then–defence minister Paul Hellyer. The controversial merger resulted in the abolition of the RCN as a separate legal entity. All personnel, ships, and aircraft became part of Maritime Command (MARCOM), an element of the CAF. The traditional naval uniform was eliminated and all naval personnel were required to wear the new CAF rifle green uniform, adopted also by former Royal Canadian Air Force and Canadian Army personnel. The unification of the Canadian Forces in 1968 was the first time that a nation with a modern military combined its formerly separate naval, land and air elements into a single service.

Following the Official Languages Act enshrinement in 1969, MARCOM instituted the French Language Unit, which constituted a francophone unit with the navy. The first was . In the 1980s and 1990s, women were also accepted into the fleet, with the submarine service the last to allow them, beginning in 2001.

HMCS Bonaventure was sold off in 1970, shortly after completing a 16-month, $11 million mid-life refit.

Some of the changes that had taken place during the unification of the forces began to be undone. In 1985, MARCOM received new black uniforms, differentiating them from the land-based forces.

As of August 2015, with the loss of area air defence and (temporarily) resupply capabilities, the RCN was then classified as a Rank 5 navy (offshore regional coastal defence) on the Todd-Lindberg navy classification system of naval strength, dropping from Rank 3 (multiregional power projection) in 2005. Vice-Admiral Angus Topshee, the commander of the RCN, indicated in 2023, the "effective strength" of the regular force was considerably lower with numerous naval trades having shortages in trained strength of more than 20 percent. In late 2025, Vice-Admiral Topshee stated that the Navy's personnel problem had not been solved and remained dire, while the Auditor General of Canada reported deeper systemic problems with Canadian military recruitment.

In December 2025, Iran designated the Royal Canadian Navy as a “terrorist organization”. Iran's foreign ministry stated the decision was made “within the framework of reciprocity”, after the Government of Canada listed the Islamic Revolutionary Guard Corps (IRGC) as a terrorist entity in 2024.

Structure

The Royal Canadian Navy is the maritime component of the Canadian Armed Forces, led by the commander of the Royal Canadian Navy. The commander of the RCN reports to the chief of Defence Staff, who, in turn, reports to the minister of National Defence, the head of the Department of National Defence.

The RCN is directed through Naval Staff Headquarters in Ottawa by the commander of the RCN, typically a vice-admiral. In addition to the commander, Naval Staff Headquarters also includes the deputy commander, typically a rear admiral, and the Chief Petty Officer of the Navy, the command's senior non-commissioned sailor. The RCN has three formations responsible to the commander of the RCN, Maritime Forces Atlantic, Maritime Forces Pacific, and the Canadian Forces Naval Reserve.

Maritime Forces Atlantic

Maritime Forces Atlantic comprises the RCN's naval units on Canada's Atlantic coast. Its units include the Canadian Fleet Atlantic, CFB Halifax, Maritime Forces Atlantic Headquarters, Fleet Maintenance Facility Cape Scott, and CFS St. John's. Maritime Forces Atlantic Headquarters and Fleet Maintenance Facility Cape Scott are situated within the eastern portion of CFB Halifax, His Majesty's Canadian Dockyard, Halifax, while the latter station is located in St. John's, Newfoundland and Labrador.

Maritime Forces Atlantic Headquarters serves as the formation's command centre and from where the formation commander gives direction to subordinate units.

Maritime Forces Pacific

Maritime Forces Pacific comprises the RCN's naval forces and units on Canada's Pacific coast. The formation is based in Esquimalt, British Columbia, and employs roughly 4,000 military and 2,000 civilian personnel.

Its units include Canadian Fleet Pacific, CFB Esquimalt, Fleet Maintenance Facility Cape Breton, Fleet Diving Unit Pacific, and Naval Training Development Centre (Pacific). Canadian Fleet Pacific includes 13 ships and two submarines.

The formation includes the Naval Reserve Headquarters and 24 Naval Reserve divisions (NRD). The Naval Reserve Headquarters, located in Quebec City, coordinates the activities of the 24 NRDs spread across the country. Naval reservists typically parade at their local NRD one or two times per week to conduct training and maintain operational readiness. The majority of naval reservists serve on a part-time basis, though some serve full-time.

Fleet

The Royal Canadian Navy operates a number of warships, patrol vessels, submarines and training vessels. In addition to its operational warships and auxiliary vessels, , a former World War II-era destroyer and museum ship moored in Hamilton, Ontario, is formally commissioned as the navy’s ceremonial flagship. However, internal reports from the Department of National Defence in 2024 reported that approximately 54 per cent of the RCN's equipment was unservicable, primarily due to manpower and funding shortfalls.

RCN ships may carry aircraft and specialized crews, including advanced naval capability (ANC) units and clearance divers. ANC personnel and its maritime tactical operators, are used for maritime interdiction operations, harbour defence and force protection. Clearance divers are specialists responsible for mine countermeasures diving, maritime explosive ordnance disposal, improvised explosive device disposal, and underwater engineering support. They are based in CFB Esquimalt and CFB Halifax, and with additional detachments in Toronto and within Canadian Special Operations Forces Command.

Surface fleet

The surface fleet includes several classes of armed vessels. This includes 12 Halifax-class frigates, which forms the backbone of the surface fleet. The frigates are used in a wide range of missions, including peacekeeping support, humanitarian assistance, disaster relief operations, and combat operations. The first in its class entered service in 1992, with the class receiving mid-life refits in the 2010s. The class is intended to be replaced by the River-class destroyer, a design selected in 2018 to replace both the Halifax-class and the already retired Iroquois-class destroyers. As of 2025, up to 15 ships have been planned, with the first expected to enter service in the 2030s.

The RCN also operate five Harry DeWolf-class offshore patrol vessel, a class of Arctic and offshore patrol vessels designed to patrol Canadian Arctic and coastal waters and support international operations, including surveillance, search and rescue, humanitarian assistance, emergency response, and disaster relief. The first Harry DeWolf-class entered service in 2021. A sixth ship was delivered, although it is not yet in service.

Four Kingston-class coastal defence vessel remain in service with the RCN. The Kingston-class are multi-role minor warships used primarily for coastal surveillance, patrol operations, search and rescue, law enforcement support, resource protection, fisheries patrols and training. Entering service in 1996, there were initially 12 Kingston-class vessels in service, although the class has been gradually paid off and retired. The Continental Defence Corvette is an RCN project to replace the retiring Kingston-class, although a contract to build the class has not yet been awarded.

The RCN also acquired CSS Asterix in 2015 as a stopgap to provide replenishment capability from the retirement of the Protecteur-class replenishment oilers to the introduction of its replacement, the Protecteur-class auxiliary vessels. In addition to replenishment, the Protecteur-class auxillary vessel will also provide limited sealift capacity and support for naval operations ashore. The design was selected in 2014, with construction beginnning for the first of two ships in 2020.

Submarines

The RCN operates four Victoria class submarines, , , , and . The submarines are used to support the RCN's maritime and defence capabilities, using them for surveillance, intelligence gathering, maritime security operations and law enforcement, counter-narcotics and anti-smuggling operations, environmental monitoring, and Arctic and continental defence missions. They also provide combat capabilities in support of naval operations.

The four Victoria-class submarines first entered service with the Royal Navy in the 1990s. The submarines were later acquired by Canada, with the first entering RCN service in 2000. In 2024, the Canadian Patrol Submarine Project (CPSP) was announced to replace the Victoria class, with up to 12 submarines to be acquired by the RCN.

Training and auxillary ships

thumb|An Orca class patrol vessel in the [[Gulf Islands, 2007]]

The RCN operates nine training vessels to support the training and provide at-sea experience, , a tall ship, and eight Orca-class patrol vessels. All Orca-class vessels are based in British Columbian coastal waters and are used primarily as training ships. In addition to their training role, the vessels support community relations by participating in local events. Although they are not assigned a dedicated operational role, Orca-class patrol vessels do also conduct coastal patrols and report suspicious activity, pollution infractions, and fishing violations. They are also tasked with search and rescue operations and assisting vessels in distress.

Aircraft

Since 1975, all manned aircraft supporting the RCN have been operated by the Royal Canadian Air Force. This includes CH-148 Cyclone helicopters embarked aboard RCN ships for anti-submarine warfare, surveillance, and search and rescue operations.

From 1914 to 1945, Canadian naval aviators generally served with the Royal Navy. The RCN briefly established the Royal Canadian Naval Air Service in 1918, though it was disbanded within months. In 1945, the RCN formed the Naval Air Branch, which was later reorganized into Maritime Air Group in 1968. Maritime Air Group operated carrier-borne aircraft until 1970 and anti-submarine warfare aircraft from destroyers and shore bases until 1975, when Air Command assumed control over Maritime Air Group and its aircraft.

RCN personnel, typically from ANC units, do operate shipborne unmanned aerial vehicles. The RCN are also procuring Schiebel Camcopter S-100 and are planned to enter service in 2027 or 2028.

Personnel

As of 2026, the Royal Canadian Navy reports having 8,400 Regular Force sailors and 4,100 Reserve Force sailors, in addition to employing approximately 3,800 civilian staff.

Commander-in-Chief

In their capacity as the Commander-in-Chief of Canada, the governor general of Canada is entitled to wear a distinctive general officer uniform from any of three environments: navy, army, or air force. The navy uniform features a unique general sleeve braid embellished with the governor general's badge. The badge is also embroidered on the uniform's shoulder straps.

Commissioned officers

Officers hold positions of command and responsibility. Their roles typically include overseeing personnel, planning, and directing operations, making decisions within their scope of authority, and providing advice to achieve operational objectives.

The rank insignia for RCN general officers, like those of other Canadian Armed Forces general and flag officers, features maple leaves, the number of which corresponds to the officer's rank. The rank insignia for senior and junior officers is made up of gold laces, with the number and spacing of the laces varying by rank, and an executive curl surmounting the lace. The rank insignia for subordinate officers is made up of only a singular gold lace.

RCN officers are commissioned through multiple entry plan, each tailored for officer candidates with different educational backgrounds and military experience, to develop them to the proficiency expected of an officer. This typically includes providing pathways to complete an academic degree, either through a Canadian military college or another Canadian university. Other pathways include the Direct Entry Officer Plan for candidates who already possess an academic degree, and the Continuing Education Officer Training Plan for select candidates who are otherwise qualified for service as officers but lack an academic degree. There are also several entry plans to facilitate the transition of non-commissioned members.

Candidates seeking entry as an officer in the CAF are required to pass Basic Military Officer Qualification at Canadian Forces Leadership and Recruit School in Saint-Jean-sur-Richelieu.

Non-commissioned members

Non-commissioned members in the RCN perform operational and support duties and contribute to maintaining safety, discipline, and the welfare of their units. In addition to the standard entry pathway, the RCN also operates the Naval Experience Program, an alternative introductory program that allows recruits to complete basic military and naval familiarization training while exploring naval life and occupations before committing to a specific trade.

In August 2020, the RCN replaced the term seaman in its non-commissioned member rank titles with the gender-neutral term sailor as part of a broader modernization of rank designations.

Uniforms

All CAF uniforms, including the RCN, are categorized into five types, including No. 1 Dress (ceremonial dress), No. 2 Dress (mess dress), No. 3 Dress (service dress), No. 4 Dress (occupational dress), and No. 5 Dress (operational dress). Uniforms worn by the RCN are regulated by the Dress Instructions for the Canadian Forces. Misuse of the likeness of Canadian Army uniforms is an offence under Article 419 of the Criminal Code of Canada and is punishable by summary conviction.

The RCN's service dress uniform consists of a dark navy blue double-breasted coat and trousers, worn with a white long-sleeved shirt and black necktie. The service dress uniform is also used for ceremonial occasions, worn with medals and ribbons, as the RCN no longer maintains a unique ceremonial full dress uniform. In addition to its navy blue uniforms, the RCN also maintains white uniforms for ceremonial and service dress wear during the summer months.

The RCN's operational dress includes uniforms worn during operations, operational training, or as directed. Operational uniforms are used across the entire CAF and are not specific to any single environmental command. This badge remained in use until the unification of the CAF on 1 February 1968.

When the Royal Canadian Navy became the Canadian Forces Maritime Command in 1968, the branch received a new badge. This badge included a flying eagle along with the anchor, representing the air arm of the navy. It also included a motto, "Ready Aye Ready".

Following the reinstatement of the Royal Canadian Navy name in 2011, a new badge was approved in 2016, featuring St. Edward's Crown, a fouled anchor within a circlet, a compartment of maple leaves, and its motto at the bottom. In 2026, the Canadian Royal Crown replaced St Edward's Crown on the badge.

Flags

The RCN uses a variety of flags, including those indicating Canadian nationality, such as the naval ensign and naval jack, as well as ceremonial flags reflecting naval tradition, including the King's Colours and a commissioning pennant.

Colours

thumb|King [[George VI presenting the King's Colour to the RCN during his 1939 royal tour]]

The RCN was granted the right to use the King's Colour in 1925 by King George V. The Queen's or King's Colour (also referred to as the sovereign's colour) for the Navy has been consecrated and presented four times: in 1939 by King George VI in Esquimalt, in 1959 by Queen Elizabeth II in Halifax, in 1979 by Queen Elizabeth the Queen Mother in Halifax and in 2009 by the Governor General and Commander-in-Chief Michaëlle Jean in Halifax.

The colour used by the RCN between 1927 and 1936 was never actually presented but went straight into service in both the Atlantic and Pacific commands. Two identical colours were presented, one for the Atlantic fleet and one for the Pacific fleet, in 1926, 1939 and 1959, but only one colour was presented in 1979 and 2009. Th active 1979 and 2009 colour is maintained in RCN Headquarters in Ottawa and dispatched to ceremonies whenever it is needed.

Commissioning pennant

RCN commissioning pennants are flown at a ship's masthead. Since the early 1990s, the RCN has used a commissioning pennant featuring a red maple leaf, replacing the original Saint George's Cross design shared with the Royal Navy. The pennant is hoisted on the date of the ship's commissioning and is only displaced by the Sovereign's Flag for Canada or the rank flag of another senior officer when embarked. Historically, some formations and individual ships kept live animals on board as companions, mascots and pets, a practice that continued even after the RCN formally prohibited pet animals aboard ships.

Museums and memorials

thumb|The [[Royal Canadian Navy Monument in Ottawa, 2012]]

The RCN maintains five naval museums to chronicle the history of the navy, CFB Esquimalt Naval and Military Museum, the Naval Museum of Halifax, the Naval Museum of Alberta, the Naval Museum of Manitoba, and the Naval Museum of Quebec. In addition to RCN-maintained museums, several civilian institutions also preserve and interpret the navy's history, including the Canadian War Museum, a Canadian national museum operated by a Crown corporation in the Department of Canadian Heritage's portfolio, as well as independently operated institutions such as the Maritime Museum of the Atlantic and the Maritime Museum of British Columbia. The navy's ceremonial flagship, HMCS Haida, is a museum ship.

Several public memorials have been erected to commemorate Canadian veterans and war dead. Most memorials commemorate Canadian veterans and war dead from all services, while others, like the Halifax Memorial, the Montreal Clock Tower, and the Naval Memorial Monument in Burlington, Ontario, commemorate sailors from both the RCN and the Canadian Merchant Navy. However, there are some monuments specifically dedicated to RCN sailors, like the Royal Canadian Navy Monument in Ottawa.
