Lake Ontario

Lake Ontario is the eastern-most and smallest in surface area (18,960 square kilometers) of the Great Lakes. It exceeds only Lake Erie in volume. Its primary inlet is Niagara Falls (from Lake Erie) and primary outlet is the Saint Lawrence River. A portion of the Great Lakes Waterway passes through the lake, which is accessible from upstream by the Welland Canal and from downstream by the Saint Lawrence Seaway. The Trent-Severn Waterway for pleasure boats connects Lake Ontario to Georgian Bay[?] of Lake Huron through Lake Simcoe[?].

Other notable geographic features are Hamilton Harbour[?], the Bay of Quinte, and the Toronto Islands.

The southern, American shore of the lake is largely rural, with the exception of Rochester, New York. A large conurbation called the Golden Horseshoe[?](including Toronto and Hamilton, Ontario) is to be found on the Canadian side.
