Security and enforcement Since the start of Metro service in 1966, the STM (and predecessors) has had its own transit enforcement unit. Since 2021, the transit officers are sworn as Special Constables. They now be subject to the Police Act and, consequently, the authority of the Commissaire à la déontologie policière (police ethics commissioner). In addition, the Bureau des enquêtes indépendantes (BEI) will be able to take over investigations as needed. In Quebec, special constables are peace officers. Their mission is to maintain peace, order and public security, to prevent and repress crime and, according to the jurisdiction specified in their deeds of appointment, to enforce the law and municipal by-laws, and to apprehend offenders. The Service de police de la Ville de Montréal has a Unité métro (Metro Unit) that patrols Metro trains and stations as well. This unit has been in service since 2007. Incidents On May 10, 2012, smoke bombs were set off at Lionel-Groulx, Jean-Talon, Préfontaine, Fabre and Pie-IX stations, resulting in evacuations of the affected stations and a complete shutdown of the Metro for over two hours. The incident was not officially linked to the 2012 Quebec student strike. In 2009, a woman was arrested, handcuffed, and searched by Laval Police Service () officers for allegedly not holding an escalator handrail. Her case was rejected by both Quebec Superior Court and the Quebec Court of Appeal. In November 2018, the Supreme Court of Canada agreed to hear her appeal and in November 2019, ruled that her arrest and subsequent search were unlawful and had violated her rights. The court also awarded her $20,000 in damages.
