Below the provincial level of government, Saskatchewan is divided into urban and rural municipalities. The Government of Saskatchewan's Ministry of Municipal Relations recognizes three general types of municipalities and seven sub-types – urban municipalities (cities, towns, villages and resort villages), rural municipalities and northern municipalities (northern towns, northern villages and northern hamlets).[16] The vast majority of the land mass of Northern Saskatchewan is within the unorganized Northern Saskatchewan Administration District. Cities are formed under the provincial authority of The Cities Act, which was enacted in 2002.[17] Towns, villages, resort villages and rural municipalities are formed under the authority of The Municipalities Act, enacted in 2005.[18] The three sub-types of northern municipalities are formed under the authority of The Northern Municipalities Act, enacted in 2010.[19] As provincial laws, these three acts were passed by the Legislative Assembly of Saskatchewan with royal assent granted by the Lieutenant Governor.
