This building, typical of military architecture of its period, was built in 1886 to provide quarters for the recently authorized "D" Company, Infantry School Corps, an early step in the development of the Permanent Forces of Canada. In 1901, after three changes, the Corps was renamed the Royal Canadian Regiment. Regimental Headquarters moved here in 1923.
During the years 1914-18 and 1939-45 while the regiment was on active service the building was used for recruiting, training and demobilization. The Regiment returned to the Barracks in 1953.
