Cornwall

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 Ontario's easternmost city. Although it is the seat of the United Counties of Stormont, Dundas and Glengarry, Cornwall is administered independently from the county.

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.
