forage caps at all times. In British Columbia, Alberta, and Quebec, this requirement no longer exists, although some police services still require that frontline police officers wear some form of headgear. Beginning in the mid-2010s, an increasing share of police forces in Ontario have allowed frontline officers to wear ballcaps instead of forage caps. Vehicles As part of their authority to establish, maintain, and regulate law enforcement agencies, some provinces regulate the models of vehicle that can be used by police services for frontline policing. In the late 2010s and early 2020s, many Canadian police services began ordering vehicles painted grey, navy blue, or black to replace white- and silver-coloured cruisers, sparking controversy about their accessibility to the public and visibility in low-light conditions. More recently, in the early 2020s, some police services in Ontario began to pilot Battenburg markings. In every province and territory, police services are entitled to use red and blue lights on marked and unmarked emergency vehicles. Most special constabularies use fleets of marked police-model vehicles, and many are painted in colours that reflect the larger corporate branding scheme of their parent organization. In Alberta and Saskatchewan, vehicles maintained by special constabularies must have two blue reflective stripes, the organization's logo, and text that reads "Peace Officer" (in Alberta) or "Community Safety Officer" (in Saskatchewan) on the bottom of the passenger doors. In Quebec, special constabularies are restricted to using red emergency lights exclusively, and in Ontario, special constables can only use emergency lights or sirens if authorized by the relevant police services board. In every other province and in all three territories, including Alberta and Saskatchewan, special constabularies can use red and blue lights. Only some civil law enforcement agencies operate marked vehicles, and the exact markings vary significantly based on the role and nature of the agency. Some agencies, which are operated by police services, use vehicles that are painted in variations of the larger police force's livery, while others operated directly by municipalities or provinces may use vehicles from the larger motor pool, marked only with the parent organization's logo. In British Columbia, by-law enforcement officers are authorized to use red lights, and in Ontario, civil law enforcement officers enforcing emissions or commercial vehicle regulations may use red and blue lights and sirens. In every province and territory, civil law enforcement officers employed by conservation officer or commercial vehicle enforcement services can use
