French is a Romance language of the Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French evolved from Gallo-Romance, the Latin spoken in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) largely supplanted. French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the (Germanic) Frankish language of the post-Roman Frankish invaders. Today, owing to France's past overseas expansion, there are numerous French-based creole languages, most notably Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French.

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.

National Defence Headquarters (NDHQ) was created through the integration of Canadian Armed Forces Headquarters with the civilian Department of National Defence (DND) staff in October of 1972. NDHQ is not a specific location, but is instead housed throughout a collection of offices in buildings across the National Capital Region, although it is most commonly identified with the Major-General George R Pearkes Building on Colonel By Drive in Ottawa.

Ottawa is the capital city of Canada. It is located at the confluence of the Ottawa River and the Rideau River in the southern portion of the province of Ontario. Ottawa borders Gatineau, Quebec, and forms the core of the Ottawa–Gatineau census metropolitan area (CMA) and the National Capital Region (NCR). As of 2021, Ottawa had a city population of 1,017,449 and a metropolitan population of 1,488,307, making it the fourth-largest city and fourth-largest metropolitan area in Canada.

Ontario is one of the thirteen provinces and territories of Canada. Located in Central Canada, it is Canada's most populous province, with 38.3 percent of the country's population, and is the second-largest province by total area. Ontario is Canada's fourth-largest jurisdiction in total area when the territories of the Northwest Territories and Nunavut are included. It is home to the nation's capital city, Ottawa, and the nation's most populous city, Toronto, which is Ontario's provincial capital.

The chief of the Defence Staff is the professional head of the Canadian Armed Forces. As the senior military position, the chief of the Defence Staff advises the Cabinet, particularly the minister of national defence and the prime minister. The role is a Crown-in-Council appointment made by the viceroy on the advice of the prime minister.

The commander-in-chief of the Canadian Armed Forces exercises supreme command and control over Canada's military, the Canadian Armed Forces. Constitutionally, command-in-chief is vested in the Canadian monarch, presently King Charles III. Since the Letters Patent, 1947, were signed by King George VI, the governor general of Canada—presently Mary Simon—executes most of the duties of the sovereign, including in his role as commander-in-chief. Consequently, the governor general also uses the title Commander-in-Chief of the Canadian Forces. By protocol, the title used within international contexts is Commander-in-Chief of Canada.
