Introduction
Le Chemin de Fer Ontario Northland, ou Ontario Northland Railway en anglais (ONR), est un chemin de fer canadien et une compagnie de la couronne provinciale. The Ontario Northland Railway (ONR, AAR reporting marks ONT, ONTA) is a Canadian railway and provincial Crown corporation. Its north-south mainline has a southern terminus at North Bay, passing through Cochrane, and a northern terminus at Moosonee, on the south shore of James Bay - all in its namesake province of Ontario. An east-west secondary mainline connects Calstock (near Hearst) with Cochrane and a line extends from Swastika (south of Cochrane) into the neighbouring province of Quebec where it terminates at Rouyn-Noranda. The railway's forty kilometres of track in Quebec are operated by a subsidiary, the Nipissing Central Railway.
Originally built to develop the Lake Timiskaming and Lake Nipissing areas, this railway soon became a major factor in the economic growth of the province. After decades of hard construction through the Canadian Shield it reached James Bay in 1932. While blasting the route through the shield, geologists discovered vast deposits of valuable minerals such as gold, silver, copper and nickel. The railway also made it possible to exploit the vast timber resources of Northern Ontario. The importance of the ONR is witnessed by the vast increase in mineral exploration and exploitation, giving rise to the valuable mining stocks on the Toronto Stock Exchange and indirectly leading to Southern Ontario's economic boom during the 1970s.
