It is located on the historical site of Fort Saint-Jean, in Saint-Jean-sur-Richelieu, Quebec, 40 km south of Montreal.

RMC Saint-Jean is an arm of the Canadian Military College (CMC) system that provides two college-level programs in Social Science and Science, which are closely integrated with the undergraduate programs offered by the Royal Military College of Canada.

RMC Saint-Jean was granted independent university status in 2021, and it currently offers a bachelor's degree in International Studies.

The mandate of the preparatory year is to develop in its students good work habits, academic diligence, critical facility, and team spirit.

This program is designed for officer candidates to obtain a bachelor degree (which is required to be an officer in the Canadian Armed Forces) while attending either the Royal Military College in Saint-Jean or the Royal Military College of Canada in Kingston, Ontario.

To further their leadership skills and abilities, Officer/Naval cadets are appointed to positions of responsibility according to merit or a need for development.

During the week, the daily routine consists of inspection, running, breakfast, classes, sports, and studies.

The military training is in the form of drill, cartography, compass use, and two major field exercises each year.

The new RMC Saint-Jean encompasses the Canadian Forces Management and Development School, one of the oldest CF training establishments in the country.

It is also the home to the Chief Warrant Officer Robert Osside Profession of Arms Institute, which develops the prospective future senior leaders of the Canadian Forces NCM Corps.

The campus provides technological support: library, laboratories, learning materials, and Internet access.

The museum's mandate is to collect, conserve, research and display material relating to the history of the CMR, its former cadets and its site, Saint-Jean-sur-Richelieu.

[26] The CMR Ex-Cadet Foundation manages the museum which recognizes more than 325 years (1666–1995) of military history at the fortifications located on the Richelieu River.

The RMC Saint-Jean art collection includes a bronze sculpture of a cadet 'Truth Duty Valour (1976)', by William McElcheran (Canadian 1927–1999) "Presented to ‘Le Collège Militaire Royal de Saint-Jean’ by the commandant, staff & cadets of R.M.C., Canada on the occasion of the sister College's visit, 12–17 May 1976".

[27] In 2006, while Hélène Ladouceur served as curator, the museum site moved from the old guardhouse to the entrance of the former Protestant Chapel.

In May 2012, while Eric Ruel served as curator, the museum relocated to the historical pavilion "les Forges".

Potential candidates must have studied at, been employed as a member of the faculty or staff at, or have had a notable involvement with Royal Military College Saint-Jean over the course of its existence since 1952.
