Cornwall is a city in Eastern Ontario, Canada and the seat of the United Counties of Stormont, Dundas and Glengarry, Ontario. Cornwall is Ontario's easternmost city, located on the St. Lawrence River, Quebec City-Windsor Corridor and Ontario Highway 401, and is the urban centre for surrounding communities, which include Long Sault and Ingleside to the west, Mohawk Territory of Akwesasne to the south, St. Andrew's and Avonmore to the north, and Glen Walter, Martintown, Williamstown, and Lancaster to the east. Cornwall is located approximately 60 mi southeast of Ottawa, the national capital, 70 mi southwest of Montreal, Quebec's largest city, and 250 mi northeast of Toronto, the provincial capital. It is named after the English county of Cornwall, which is represented in the city's flag and coat of arms—both of which boast the duchy standard.
