James Bay Energy Co. operated several Convair 580s supporting the James Bay Hydro electric project in Northern Quebec. This Convair was servicing the project from 1977 through 1994. Sold to Hydro Quebec, the state owned public utility, it remained in Canada until 2002.

This 1953 Convair was built as a 340 for Delta Air Lines (N4802C). Bought by North Central Airlines in 1962, it was converted to a 580 in 1969. Bought by the James Bay Energy Corporation in 1976 for transportation to their giant hydro-electric project in Northern Quebec. Operated at first by Quebecair for the company, Inter-Quebec and Air Inuit took over as the aviation scene changed in Canada. Sold to the public utility Hydro-Québec in 1994, the airliner was withdrawn in 2001 and the registration cancelled at the end of that year.
