Cornwall is a city in Eastern Ontario, Canada, situated where the provinces of Ontario and Quebec and the U.S. state of New York converge. It is the seat of the United Counties of Stormont, Dundas, and Glengarry and is Ontario's easternmost city. Cornwall is named after the English Duchy of Cornwall; the city's coat of arms is based on that of the duchy with its colours reversed and the addition of a "royal tressure," a Scottish symbol of royalty. It is the urban centre for the surrounding communities of Long Sault and Ingleside to the west; the Mohawk Territory of Akwesasne to the south; St. Andrews West and Avonmore to the north; and Glen Walter, Martintown, Apple Hill, Williamstown, and Lancaster to the east. The city straddles the St. Lawrence River and is home to the St. Lawrence Seaway Management Corporation, which oversees navigation and shipping activities for the St. Lawrence Seaway. It lies within the Quebec City–Windsor Corridor along Ontario Highway 401, is a major port of entry from the United States into Canada, and is positioned to support some of Cornwall's largest industries, which include logistics, distribution, and call centres.

Cornwall Street Railway Light and Power Company Limited, operating as Cornwall Electric, is an electricity transmission and distribution utility, licensed by the Ontario Energy Board (OEB) to operate in Cornwall, Ontario, Canada. Originally established in 1887 as the Stormont Electric Light and Power Company and merged with the Cornwall Electric Street Railway Company in 1905, it is one of the oldest utilities in Canada. The company supplies electricity to approximately 25,365 customers in the city of Cornwall, the townships of South Glengarry and South Stormont, and on a portion of the Mohawk people's territory of Akwesasne, all located in Eastern Ontario. It crosses provincial boundaries to obtain the bulk of the power it requires directly from Hydro-Québec, while generating a small amount of its own, using a cogeneration system, a first such use in Canada. Thomas Edison visited Cornwall in 1883 to see his electric incandescent light system illuminate a local factory. The incorporation of the Stormont Electric Light and Power Company followed in 1887. Since then, the company has undergone several ownership changes during its history, transitioning from a private company to a municipally owned utility to one that is owned and operated by a multinational publicly traded company.

The Seaway International Bridge is an international crossing connecting the U.S. state of New York, Akwesasne Mohawk Territory, and the Canadian province of Ontario. It consists of the South and North Channel Bridges. The South Channel Bridge was opened in 1958, and spans the St. Lawrence Seaway. The North Channel Bridge, opened in 2014, connects the City of Cornwall in Ontario to Cornwall Island in Akwesasne Mohawk Territory. The bridge is among the busiest on the Canada–United States border in the state of New York, with about two million crossings a year. It is jointly owned by the Federal Bridge Corporation (a Crown corporation of the Canadian federal government) and the Great Lakes St. Lawrence Seaway Development Corporation (an agency of the United States Department of Transportation), and is operated by the Seaway International Bridge Corporation, which came under the control of the Federal Bridge Corporation from the Saint Lawrence Seaway Authority in 1998. Previously known as the Cornwall-Massena International Bridge, the SIBC was a private bridge whose outstanding stock was purchased by the Saint Lawrence Seaway Authority (Canada) and the Saint Lawrence Seaway Development Corporation (U.S.) in 1957. It was incorporated in Canada five years later. In 2000, the international border crossing that the Seaway International Bridge comprises was named the Three Nations Crossing, in recognition that it connects the Akwesasne Mohawk Territory, a self-governing nation, to the United States and Canada. On January 24, 2014, the opening of a new lower-level bridge marked the official closing of the former high-level North Channel crossing of the Seaway International Bridge. This project was estimated to cost $75 million, entirely funded by the Government of Canada. It was announced in 2010 that the Government of Canada would be going forward with this project that would involve the construction of a new low-level bridge as well as the demolition of the Seaway International Bridge to ensure the longevity of the border crossing, assuring that the former bridge was still in safe driving condition. The high-level Seaway International Bridge was completely demolished in 2015. At the opening ceremony of the new bridge, the first person to make the crossing was Raymonde Champagne, who had also been the first person to cross the high-level bridge in 1962.
