Law enforcement was supplied mainly by municipal forces, either an independent police department or the Royal Canadian Mounted Police (RCMP). Municipalities with populations over 5,000 people using the RCMP paid either 90% or 70% of their costs, depending on their population size, with the federal government paying the remainder. Those municipalities under 5,000 people shared a detachment with the general rural area but did not pay any of the policing costs while the unincorporated rural areas paid a small, varied, amount through a general rural property tax. Other police forces operating within BC include 2 First Nations forces, a RCMP federal force, the Greater Vancouver Transportation Authority Police Service (now South Coast British Columbia Transportation Authority Police Service), the Organized Crime Agency (Combined Forces Special Enforcement Unit), Conservation Officer Service, the Canadian National and Canadian Pacific railway police forces, and various municipal bylaw enforcement officers.
