The riding of Nickel Belt was created in 1952 from parts of Algoma East, Algoma—Manitoulin, Nipissing, Parry Sound—Muskoka, Sudbury and Timiskaming—Cochrane ridings. It has traditionally included much of the Sudbury District and small parts of the Algoma, Nipissing and Timiskaming Districts, along with all but the urban core of Greater Sudbury. It consisted initially of parts of the territorial districts of Sudbury and Algoma, and excluding the city of Sudbury, town of Copper Cliff, and the township of McKim. In 1966, it was redefined to consist of parts of the territorial districts of Sudbury excluding the City of Sudbury and the Town of Copper Cliff, and the northeast part of the territorial district of Manitoulin. In 1976, it was redefined to consist of the southern part of Regional Municipality of Sudbury, the southeast part of the Territorial District of Sudbury, and the part of the Territorial District of Manitoulin including and lying east of the Townships of Killarney, and Rutherford and George Island. In 1987, it was redefined to consist of the southern part of the Regional Municipality of Sudbury; the geographic townships of Cartier, Cascaden, Foy, Hart, Harty, Hess and Moncrieff and that part of the geographic Township of Trill not within the Town of Walden in the Territorial District of Sudbury; Wahnapitei Indian Reserve No. 11; and Whitefish Lake Indian Reserve No. 6.

the Territorial District of Sudbury excluding:
* the part lying west of the eastern boundary of the townships of Shenango, Lemoine, Carty, Pinogami, Biggs, Rollo, Swayze, Cunningham, Blamey, Shipley, Singapore, Burr and Edighoffer;
