Early sources make little mention of a museum within the premises, yet the idea clearly sprung in the years following the demobilization after the First World War (1919 to 1924), when regimental sources recognize the importance of “assembling the regimental history." This history was eventually published in 1933, as a volume featuring the first 50 years of The RCR.
The efforts of organizing a regimental museum at Wolseley Barracks came to a full stop at the outbreak of the Second World War. Once the conflict was over, more exactly in fall 1947, the museum was coming to an “opening stage” , but only in 1953 a permanent location was assigned, nothing less than the 2nd floor of the Barracks’ west wing, above the archway entrance, which coincides with the “museum room” from the 1886 floor plans.
However, it will not be until the early 1970s that the museum takes shape, with an important expansion project in 1983, on the ocasion of The RCR centenial. More recently, in 2010-2012, the museum expanded its footprint to occupy the entire west wing of Wolseley Barracks.
