All but a small portion of Ontario's 2,700 km (1,677 mi) border with the United States follow Inland Waterways: from the west at Lake of the Woods, eastward along the major rivers and lakes of the Great Lakes/St. Lawrence River drainage system.
These are the Rainy River, Lake Superior, the St. Mary's River, Lake Huron, the St. Clair River, Lake St. Clair, Lake Erie, the Niagara River, Lake Ontario, and along the St. Lawrence River from Kingston, Ontario to the Quebec boundary just east of Cornwall, Ontario.
INLAND WATERWAYS:-
A body of water, such as a river, canal or lake, is navigable if it is deep, wide and slow enough for a vessel to pass. Preferably there are few obstructions such as rocks or trees to avoid. Bridges must have sufficient clearance. High water speed may make a channel unnavigable. Waters may be unnavigable because of ice, particularly in winter. Navigability depends on context: A small river may be navigable by smaller craft, such as a motor boat or a kayak, but unnavigable by a cruise ship. Shallow rivers may be made navigable by the installation of locks that increase and regulate water depth, or by dredging.
ST. LAWRENCE RIVER:-
The St. Lawrence River is a large flowing approximately from southwest to NorthEast in the middle latitudes of North America, connecting the Great Lakes with the Atlantic Ocean. It is the primary drainage of the Great Lakes Basin. The river traverses the Canadian provinces of Quebec and Ontario and forms part of the international boundary between Ontario and New York in the United States.
LAKE HURON:-
Lake Huron is one of the five Great Lakes of North America. Geologically, it comprises the larger portion of Lake Michigan-Huron. It is bounded on the east by the Canadianprovince of Ontario and on the west by the state of Michigan in the United States. The name of the lake is derived from early French explorers who named it based on the Huron people inhabiting the region.
NIAGARA RIVER:-
The Niagara River flows north from Lake Erie to Lake Ontario. It forms part of the border between the Province of Ontario in Canada and New York State in the United States."Niagara" is derived from the name given to a branch of the locally residing native Neutral Confederacy, who are described as being called the "Niagagarega" people on several late 17th century French maps of the area.
The river, which is occasionally described as a strait is about 56 kilometres long and includes Niagara Falls in its course.
LAKE ERIE:-
Lake Erie is the fourth largest lake (by surface area) of the five Great Lakes in North America, and the thirteenth largest globally. It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time. It is bounded on the north by the Canadian province of Ontario, on the south by the U.S. states of Ohio, Pennsylvania, and New York, and on the west by the state of Michigan. The lake is named after the Erie tribe of Native Americans who lived along its southern shore.
