The RCMS has its origins in the Dominion government's 1885 response to the North-West Rebellion, with the appointment of Canada's first Surgeon General, Doctor Darby Bergin of Cornwall, Ontario, and the mobilization of two field hospitals. Permanent medical services for the Canadian Army (1904), Royal Canadian Navy (1910) and Royal Canadian Air Force (1940) were formed separately (years indicated). The three services were subsequently integrated as a single professional/technical organization, the Canadian Forces Medical Service (CFMS), in 1959. Personnel of the CFMS continued to belong to the Navy, Army and Air Force in matters of personnel administration. With the unification of the Canadian Forces (CF) in 1968, medical personnel the RCN, Canadian Army and RCAF were grouped administratively into the new CF Medical Branch, perfectly aligned to the professional/technical organization of the CFMS.
