Black Nova Scotians are Black Canadians whose ancestors fled the Colonial United States as slaves or freemen, and later settled in Nova Scotia, Canada during the 18th and early 19th centuries. As of the 2011 Census of Canada, 20,790 black people live in Nova Scotia, most in Halifax, though a large number of Black Nova Scotians have migrated to Toronto, Ontario since the 1950s. Before the immigration reforms of the 1960s, Black Nova Scotians formed 37% of the total Black Canadian population.
