Sister cities of Brockville

Brockville, formerly Elizabethtown, is a city in Eastern Ontario, Canada, in the Thousand Islands region. Though it serves as the seat of Leeds and Grenville United Counties, Brockville is politically independent and is grouped with Leeds and Grenville for census purposes only.

Known as the "City of the 1000 Islands", Brockville is located on the north shore of the Saint Lawrence River, directly opposite Morristown, New York, about half-way between Cornwall in the east and Kingston in the west, and roughly a 50-minute drive to the national capital of Ottawa. It is one of Ontario's oldest urban centres, and is named after the British general Sir Isaac Brock.
