Sûreté du Québec

La Sûreté du Québec (French for "Quebec Security" or "Quebec Security Service", normally left untranslated in English-language sources) is the provincial police of the Canadian province of Québec. Sûreté is a French word which has traditionally been used in many francophone countries and regions to refer to the state's main law enforcement agency and security services; the Sûreté du Québec is sometimes known informally in English as the Quebec Police (Service). The Sûreté du Québec also functions as Quebec's provincial sheriff service, responsible for transporting prisoners and other detainees and providing plainclothes security details for senior provincial government, amongst other duties normally handled by a separate sheriff service. It is the only agency out of the twelve Canadian provinces to combine the duties of both provincial police and provincial sheriff; the eleven other provinces each have a separate provincial police and provincial sheriff service.

Each county of Quebec has its own county constabulary, responsible for policing at the local level within the respective county, namely its municipalities and unincorporated communities. The Sûreté is thus responsible for law enforcement matters affecting two or more counties or the province as a whole.
