The Sûreté du Québec, abbreviated SQ, is the provincial police service for the Canadian province of Quebec. No official English name exists, but the agency's name is sometimes translated to "Quebec Provincial Police" in English-language sources. The headquarters of the Sûreté du Québec are located on Parthenais Street in the city's downtown core of Montreal and the service employs roughly 5,500 officers. SQ is the second largest provincial service and fourth largest service in Canada.
