Alberta Provincial Police

The Alberta Provincial Police (APP) is the provincial police service of the Canadian province of Alberta, and one of two law enforcement agencies of the Government of Alberta, the other being the Alberta Sheriff's Office (ASO). It is responsible for regular policing at the provincial level, including traffic patrol of provincial and federal highways, conducting investigations and police operations at the provincial level (that is, involving more than one local government area, since each of the 75 counties of Alberta has its own county constabulary), as well as contracting with Alberta's unitary authorities (regional and municipal districts) to provide local policing. The APP is also tasked with the protection of provincial government institutions and resources, although the security of the provincial judicial system as well as the provincial government is the primary responsibility of the Alberta Sheriff's Office.

The APP also assists county constabularies with complex and/or multilateral investigations and operations, and maintains the province's largest police air division. The APP is the fourth-largest provincial police force in Canada by number of sworn officers, after the Ontario Provincial Police, the Sûreté du Québec (Quebec Provincial Police), and the British Columbia Provincial Police. It is headquartered in Edmonton, the capital and second-most populous city of Alberta. The Commissioner of the Alberta Provincial Police is the highest-ranking sworn officer and thus chief of the APP, equivalent to the rank of chief constable in county constabularies and other municipal/local police forces; the current APP Commissioner is Curtis Zablocki, in office since September 2018.
