* Ancaster is no longer a huge riding that encompasses much of West Hamilton and all of Dundas. Instead, there is now the mostly-rural Ancaster—Flamborough—Glanbrook.
* Hamilton Centre no longer exists. The lower city is now part of Hamilton West—Dundas
* The mountain is now mostly Hamilton Mountain West
* Hamilton East—Stoney Creek is gone, replaced by Hamilton East and Stoney Creek—Mountain East
