The 5th Canadian Mounted Rifles Battalion, created in 1915, was part of the 8th Infantry Brigade of the 3rd Canadian Division of the Canadian Expeditionary Force. In September 1934, members of the 5th Canadian Mounted Rifles Battalion who had served during World War I organized the 5th Canadian Mounted Rifles Association to perpetuate the memory and the tradition of their battalion. The Association was run by a four-member board elected annually. Its main activity was the annual reunion of its members, who had belonged to the 5th Canadian Mounted Rifles Battalion or the Company of the Eastern Townships Mounted Rifles. In 1967, the last meeting was held and the Association disbanded.
