The Ontario Northland Railway is a Canadian railway operated by the Ontario Northland Transportation Commission, a provincial Crown agency of the government of Ontario.

Originally built to develop the Lake Timiskaming and Lake Nipissing areas, the railway soon became a major factor in the economic growth of the province. After decades of difficult construction through the Canadian Shield, workers reached James Bay in 1932. While blasting the route through the shield, geologists discovered deposits of valuable minerals such as gold, silver, copper and nickel. The railway also made it possible to exploit the timber resources of Northern Ontario.

Its north–south mainline is located entirely in Ontario, starting at its southern terminus at North Bay, running northward through Cobalt, New Liskeard, Cochrane, and on to its northern terminus at Moosonee on the Moose River, about south of the shore of James Bay. There is one major branchline running eastward from Swastika through Kirkland Lake and over the Quebec border to end at Rouyn-Noranda. The railway's branch from Swastika to Rouyn-Noranda, including 40 kilometres of track in Quebec, is operated by a subsidiary, the Nipissing Central Railway.

Shorter spur lines also exist running west from Rock Junction to Sherman Mine, south-west from Porquis Junction to Kidd Creek Mine, about 22 km east of Timmins, north-east from Porquis to Iroquois Falls and south from Opaz Junction to Agrium mine site. Several other mining spurs opened and closed with the mines they served. Since 1993, the ONR operates a section of the National Transcontinental Railway running west from Cochrane to Calstock.

History

James Bay Railway

The line was originally chartered as the Lake Nipissing And James Bay Railway in 1884. The original route ran roughly northward from Callander to Moose River on James Bay. However, in 1902, before construction started, the Canadian Northern Railway (CNoR) took over the charter and used it as the basis for a new line running northwest from Parry Sound to Sudbury, with an additional line running from Parry Sound south to Toronto. The section running south to Toronto opened on November 6, 1906. The northern section was completed in 1908, although by this time it had been rechartered as part of the Canadian Northern Ontario Railway (CNOR).

Temiskaming and Northern Ontario Railway (1902–46) With the original plans having been dropped, and a railway on this route still desired, the new Temiskaming and Northern Ontario Railway was incorporated on 17 March 1902, by the Temiskaming and Northern Ontario Railway Act of the Ontario parliament. The railway was to be a provincial Crown corporation overseen by the Temiskaming and Northern Ontario Railway Commission. Construction on the railway started in 1903, and the settlement of Redwater in the municipality of Temagami began as a small request stop when the railway reached the area of the Lower and Upper Redwater Lakes.

As it passed by Long Lake, near the 103 mile marker, the largest silver rush in Canada was sparked by workers looking for trees for railway ties. The town of Cobalt grew out of the fortunes of silver taken from the grounds. By 1905, it reached New Liskeard in the Lake Timiskaming area. The railway reached Englehart in 1906 and Cochrane in 1909. In the next few years, several branch lines were built.

In 1921, construction on a line north to James Bay was started. In 1923, the new Conservative premier of Ontario, Howard Ferguson, halted further construction, saying that it would be unprofitable. For four years the terminus of the line remained at Fraserdale, near Abitibi Canyon, where the Abitibi Canyon Generating Station was being built on the Abitibi River. Between 1928 and 1930 the railway was extended north at a slow pace. The pace of construction was quickened in 1930 as a make-work project due to the depression. The extension to James Bay was opened on July 15, 1932. The terminus of the railway was at the mouth of the Moose River near the old trading post of Revillon Frères. It was named Moosonee, from the Cree meaning "at the moose".
