Police in Canada
For the most part, law enforcement in Canada fall under three categories; Federal, Provincial, and Municipal. The RCMP and the Canadian Forces Military Police are Canada's two federal police forces. There are also various civil law enforcement agencies including Parks Canada Park Wardens and Fisheries and Oceans Canada Fishery Officers. Provincially maintained law enforcement can be different from province to province. Large police forces such as the Ontario Provincial Police and the Sûreté du Québec can have a broad range of duties including frontline policing. Other provincial law enforcement like the Alberta Sheriffs perform more specialized services including highway patrol, prisoner transport, and fugitive apprehension. There are 138 municipal police forces in Canada, with varying size from the Toronto Police Service with 5,500 officers to Luseland, Saskatchewan's police service with only one officer. Railway police, such as the Canadian Pacific Police Service and the Canadian National Police Service, are private police forces that operate within Canada.
