Copper Cliff is a community and former company town in Greater Sudbury, Ontario, Canada. Incorporated in 1901,[1] Copper Cliff was a separate municipality until it was annexed by the City of Sudbury in 1973 as part of the creation of the Regional Municipality of Sudbury.[1]
History
When the Canadian Pacific Railway was under construction in the region in 1883, blacksmith Tom Flanagan discovered chalcopyrite deposits in the area of what is now Copper Cliff.[2] The ore was initially shipped to a smelting plant in Constable Hook, New Jersey, where it was discovered that the ore was rich in nickel.[2] Robert M.
