Amalgamation of Winnipeg
The City of Winnipeg, several surrounding municipalities and the Metropolitan Corporation of Greater Winnipeg were subject to a municipal amalgamation on January 1, 1972 that created a unicity or unified city. The creation of the current City of Winnipeg as a unicity was an ambitious experiment in local government reform. Until that point, the greater Winnipeg area comprised 12 municipalities under a single metropolitan government, in a "two-tier" system.
