2002–2006 municipal reorganization of Montreal

Montreal was one of the cities in Quebec affected by the 2000–2006 municipal reorganization in Quebec. On January 1, 2002, all the municipalities on the island of Montreal were merged into the city of Montreal.

However, following a change of government in the 2003 Quebec election and a 2004 referendum, some of those municipalities became independent cities again on January 1, 2006. The recreated cities did not regain all of their previous powers, however. A new urban agglomeration of Montreal was created, which resulted in the recreated cities still sharing certain municipal services with Montreal.
