The Alberta Provincial Police (APP) was a police force active in Alberta, Canada, between 1917 and 1932.
In 1917, the Royal Northwest Mounted Police (RNWMP) left Alberta due to a lack of sufficient resources in light of its increased responsibilities for national security during World War I and possibly its reluctance to again enforce Prohibition law recently put into effect by the Alberta government after its experience doing so during Territorial times. It was replaced by the newly created APP, which existed until 1932, when it was eliminated as a cost-cutting measure during the Great Depression.
Today the Royal Canadian Mounted Police's "K" Division is responsible for provincial policing in Alberta and the Alberta Sheriffs Branch is responsible for additional provincial law enforcement.
Known ranks on the force:
APP stations were known as barracks or detachments with about 100 when the force was created in 1917.
