new municipalities: Merger A different Progressive Conservative government amalgamated all of the constituent municipalities in Hamilton–Wentworth into the larger single-tier City of Hamilton in 2001, against great opposition from its suburban and rural parts. This was part of a broader series of municipal reorganizations in urban and rural Ontario, and was also the fate of Metropolitan Toronto, the Regional Municipality of Ottawa–Carleton, Chatham-Kent, Prince Edward County, and many others.
