Peace Officer
A peace officer is a category of public official with specific powers under the Criminal Code, including the power to arrest, search, seize, and lay charges. Section 2 of the Criminal Code defines "peace officer" broadly. The most common peace officers are sworn police officers, but the category extends to several other roles.
Who counts as a peace officer
The section 2 definition includes: police officers and police constables; mayors, reeves, and certain other elected officials in specific contexts; sheriffs, deputy sheriffs, sheriff's officers, and justices of the peace (in specific configurations); pilots in command of aircraft over Canada; correctional officers and supervisors; fishery officers, customs officers, and certain other federal regulatory officers in the performance of their statutory duties; and members of the Canadian Forces appointed for the purposes of the Code. The breadth of the definition reflects the wide range of statutory contexts in which arrest and seizure powers are required.
Powers
Peace officer status carries specific Criminal Code powers, including: arrest without warrant under section 495; arrest with warrant; investigative detention at common law and under section 31; search and seizure under various warrant provisions and at common law; demands for breath samples under section 320.27; entry to make an arrest under section 529; and laying of informations before a justice. The exact powers a particular peace officer can exercise depend on their statutory role.
Offences involving peace officers
Several Criminal Code offences specifically protect peace officers in the performance of duty: section 129 (obstruction of a peace officer); section 270 (assaulting a peace officer); section 270.01 (assault with a weapon or causing bodily harm to a peace officer); section 270.02 (aggravated assault of a peace officer). Killing a peace officer in the performance of duty supports first-degree murder under section 231(4) regardless of planning and deliberation.
Identifying yourself to a peace officer
The duty to identify oneself to a peace officer varies. Drivers must produce a licence when lawfully demanded under the Highway Traffic Act. Persons under investigative detention may have a contextual duty to identify themselves in some configurations. Persons stopped without statutory or common-law grounds for detention generally have no obligation to identify themselves. The distinction matters and is frequently the subject of Charter litigation.
Why the distinction matters
Charges and Charter applications often turn on whether the person involved was a peace officer, was acting in the performance of duty, and was lawfully exercising the powers claimed. Mass Tsang's criminal lawyers examine these issues in every case where a peace officer interaction is in dispute.
