The publication of Militia General Orders No. 93 and 94 on 15 September 1917 marked a turning point for military policing in Canada. These orders formalized the various GMP organizations into a new entity called Military Police, Canadian Expeditionary Force (MP CEF), with numbered detachments for each of the ten Military Districts across the country. In England, beginning in 1915, APMs and detachments of Canadian Military Police (CMP) were established in London, Shorncliffe, Bramshott and several other locations with large concentrations of Canadian troops. On 3 April 1918, under the authority of Headquarters Canadians Routine Order No. 3780, all Canadian Military Police in England and France were formed into a single organization called the Corps of Canadian Military Police (Corps of CMP) with an establishment of 484 non-commissioned members.
