The Otter Commission, or Otter Committee, was established after the First World War to tackle a problem created by the chaotic mobilization of the Canadian Expeditionary Force. In 1919 units of the CEF, intended as a wartime expeditionary force, returned to Canada where the Canadian Militia had served during the war performing home defence duties, staffing internment camps, and raising recruits for overseas. Both the CEF and the Militia desired to be perpetuated in the post-war world. The CEF units were proud of their wartime record, while the pre-war Militia had long-standing roots in the community and battle honours dating back as far as the War of 1812.
