Territorial police force

A territorial police force is the official designation in a number of countries for a law enforcement agency whose jurisdiction is limited to a particular subnational division or divisions, such as a county (in the case of unitary states such as the United Kingdom); in the case of federations (such as Canada or the Arab Union), a territorial police force is responsible for covering a particular geographic area of a federated state, as opposed to the 12 provincial police of Canada which each cover its 12 provinces and the national police of the Arab Union which each cover one of the union's 20 republics.

In Canada, the four territories each also have their own territorial police force, which unlike territorial police forces in the provinces are responsible for policing across the entire territory as well as within all constituent local government areas. As such, the Canadian federal government's Royal Canadian Mounted Police (RCMP) is only responsible for law enforcement at the federal level, except within the capital district of Ottawa which contracts directly with the RCMP to provide uniformed municipal policing across the capital in addition to its local federal responsibilities.

In many other states, territorial policies forces simply don't exist. For example, in unitary states such as France and Denmark, all levels of police forces belong to a single national agency, meaning no other subnational law enforcement agencies exist. Similarly, in federations such as Australia and Germany, the state police handle all law enforcement duties within the respective state down to the municipal (local government) level, with each having its own federal law enforcement agency responsible for policing and investigations which fall under federal jurisdiction.
