Nova Scotia's 50 municipalities cover 99.8% of the territory's land mass, and are home to 98.9% of its population. Nova Scotia is the seventh-most populous province in Canada with 923,598 residents as of the 2016 Census of Population, and the second-smallest province in land area at 52,942 km2 (20,441 sq mi). Unlike the provinces of British Columbia, Ontario and Quebec, which have two-tiered municipality systems, Nova Scotia has a one-tier system of municipalities inclusive of four municipality types – regional municipalities, towns, county municipalities and district municipalities. Of its 50 municipalities, Nova Scotia has 3 regional municipalities, 26 towns, 9 county municipalities and 12 district municipalities. Halifax (pictured), the provincial capital, is incorporated as a regional municipality. It is Nova Scotia's largest municipality by population with 403,131 residents as of the 2016 census and largest municipality by land area at 5,490.35 km2 (2,119.84 sq mi). (Full list...)
