armed with handguns in the wake of the 2014 Parliament Hill shooting. In Alberta, legislative security is provided by the Alberta Sheriffs Branch, an armed provincial special constabulary also responsible for courtroom security, traffic enforcement on provincial highways, and some criminal investigations. In Saskatchewan, the legislative buildings are protected by contracted security guards, but the Provincial Protective Service (responsible for the provincial highway patrol, sheriffs officers, and conservation officers) maintains a special constabulary that patrols Wascana Centre, the park that surrounds the provincial legislature. The federal parliament buildings in Ottawa are protected by the Parliamentary Protective Service, which was formed by amalgamating the House of Commons Security Services, Senate Protective Service, and the RCMP parliamentary precinct detachment. The Service, which was formed after the 2014 Parliament Hill shooting, is not a special constabulary, and only some of its members have the powers of a peace officer.

The Agency also operates a Criminal Investigations Unit that investigates criminal violations of CBSA-enforced legislation, such as smuggling or immigration fraud. The government of Canada also employs fishery officers, who enforce federal fishing and fishery regulations; transport inspectors, who enforce the 23 different pieces of federal transportation legislation the Minister of Transport is responsible for; and Environment and Climate Change Canada enforcement officers, who are responsible for enforcing federal environmental regulations.

(The RCMP disbanded its various counterparts to the CRA's criminal enforcement unit between 2012 and 2020.) The federal government also operates the Competition Bureau, which enforces the Competition Act, the Consumer Packaging and Labelling Act, the Textile Labelling Act and the Precious Metals Marking Act. Parks Canada maintains a park warden service, which is responsible for the enforcement of the Canada National Parks Act, the Species at Risk Act, and
