Riding redistribution placed Copps in a serious nomination battle with another Liberal MP, Tony Valeri, who was named to Martin's cabinet as Minister of Transport. With redistribution, part of Valeri's Stoney Creek riding was merged with part of Copps's Hamilton East to create Hamilton East—Stoney Creek, while the remainder was merged with other neighbouring ridings to create Niagara West—Glanbrook. The remaining portion of Hamilton East was merged with parts of Hamilton West to create Hamilton Centre. Of the 115,709 constituents of the riding of Hamilton East—Stoney Creek, a slight majority of constituents (58,462) were from the old Stoney Creek while a minority (57,247) were from the old Hamilton East
