Northern Ontario is a primary geographic and quasi-administrative region of the Canadian province of Ontario, the other primary region being Southern Ontario. Most of the core geographic region is located on part of the Superior Geological Province of the Canadian Shield, a vast rocky plateau located mainly north of Lake Huron, the French River, Lake Nipissing, and the Mattawa River. The statistical region extends south of the Mattawa River to include all of the District of Nipissing. The southern section of this district lies on part of the Grenville Geological Province of the Shield which occupies the transitional area between Northern and Southern Ontario. The extended federal and provincial quasi-administrative regions of Northern Ontario have their own boundaries even further south in the transitional area that vary according to their respective government policies and requirements. Ontario government departments and agencies such as the Growth Plan for Northern Ontario and the Northern Ontario Heritage Fund Corporation define Northern Ontario as all areas north of, and including, the districts of Parry Sound and Nipissing for political purposes, and the federal but not the provincial government also includes the district of Muskoka.

The Algoma Eastern Railway was a railway in Northeastern Ontario, Canada. Originally known as the Manitoulin and North Shore Railway (M&NS) with a charter dating back to 1888, the full mainline was opened to traffic in 1913, serving the area along the north shore of Lake Huron between Sudbury and Little Current on Manitoulin Island. It and its sister railway, the Algoma Central, were originally owned by the Lake Superior Corporation, a conglomerate centered on Sault Ste. Marie which was founded by the American industrialist Francis Clergue. Despite ambitious plans to expand across Lake Huron to the Bruce Peninsula using a railcar ferry, the company failed to develop further and was acquired by the Canadian Pacific Railway in 1930. With freight traffic low during the Great Depression, Canadian Pacific soon abandoned much of the Algoma Eastern mainline in favor of its own Algoma Branch. Remaining sections of the Algoma Eastern line were turned into spurs, with the longest surviving section operated as a branch line known as the Little Current Subdivision.
