The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the east-central interior of North America that connect to the Atlantic Ocean via the Saint Lawrence River. The five lakes are Superior, Michigan, Huron, Erie, and Ontario and they are in general on or near the Canada–United States border. Hydrologically, Michigan and Huron are a single body of water joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes.
Lake Ontario is one of the five Great Lakes of North America. It is bounded on the north, west, and southwest by the Canadian province of Ontario, and on the south and east by the U.S. state of New York. The Canada–United States border spans the centre of the lake.
The St. Lawrence River is a large river in the middle latitudes of North America. Its headwaters begin flowing from Lake Ontario in a roughly northeasterly direction, into the Gulf of St. Lawrence, connecting the North American Great Lakes to the North Atlantic Ocean, and forming the primary drainage outflow of the Great Lakes Basin. The river traverses the Canadian provinces of Ontario and Quebec, as well as the U.S. state of New York, and demarcates part of the international boundary between Canada and the United States. It also provides the foundation for the commercial St. Lawrence Seaway.
The Niagara River is a river that flows north from Lake Erie to Lake Ontario. It forms part of the border between the province of Ontario in Canada and the state of New York in the United States. There are differing theories as to the origin of the river's name. According to Iroquoian scholar Bruce Trigger, 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. According to George R. Stewart, it comes from the name of an Iroquois town called Ongniaahra, meaning "point of land cut in two".
The Niagara Escarpment is a long escarpment, or cuesta, in Canada and the United States that starts from the south shore of Lake Ontario westward, circumscribes the top of the Great Lakes Basin running from New York through Ontario, Michigan, and Wisconsin. The escarpment is the cliff over which the Niagara River plunges at Niagara Falls, for which it is named.
The Humber River is a river in Southern Ontario, Canada. It is in the Great Lakes Basin, is a tributary of Lake Ontario and is one of two major rivers on either side of the city of Toronto, the other being the Don River to the east. It was designated a Canadian Heritage River on September 24, 1999.
Southern Ontario is a primary region of the Canadian province of Ontario. It is the most densely populated and southernmost region in Canada, with approximately 13.5 million people, approximately 36% of Canada's population of 37 million. The region lies south of the province's other primary region, Northern Ontario, although the exact northern boundary of Southern Ontario is disputed. However, its core region is situated south of Algonquin Park, the latter being in an area of transition between coniferous forest north of the French and Mattawa Rivers and southern deciduous forest. It covers between 14 and 15% of the province, depending on the inclusion of the Parry Sound and Muskoka districts which also lie in the transitional area between northern and southern forest regions. Southern Ontario differs greatly from Northern Ontario, having a much higher population density, a different climate, and a different culture than its northern counterpart. It is broken into smaller subregions, including Central Ontario, Eastern Ontario, the Golden Horseshoe, and Southwestern Ontario.
Lake Manitou is the largest lake on Manitoulin Island in Ontario, Canada. With an area of 104 square kilometres (40 sq mi), it is the largest lake on a lake island in the world. It is drained by the Manitou River.
The Fawn River is a river in the north of the Unorganized Part of Kenora District in Northwestern Ontario, Canada. It is in the Hudson Bay drainage basin and is a right tributary of the Severn River. The Severn/Fawn basin is one of the last few remaining undammed and unregulated watersheds south of the 55th parallel in North America.
The Winisk River is a river in northern Ontario, Canada, that starts at Wunnummin Lake and flows east to Winisk Lake. From there it continues in a mostly northerly direction to Hudson Bay. The Winisk River is 475 kilometres (295 mi) long and has a drainage basin of 67,300 square kilometres (26,000 sq mi). The name is from Cree origin meaning "groundhog".
Humber Bay is a bay of Lake Ontario south of Toronto, Ontario, Canada. It is located between Ontario Place on the east and Mimico Creek to the west. The bay gives its name to Etobicoke's Humber Bay neighbourhood.
The Severn River is a river in northern Ontario. The northern Ontario river has its headwaters near the western border of the province. From the head of the Black Birch River, the Severn River is 982 km (610 mi) long, tying it with the Albany River for the title of longest river entirely in Ontario. Its drainage basin area is 102,800 km2 (39,700 sq mi), a small portion of which is in Manitoba. Its source is Deer Lake and flows northeasterly into Severn Lake, then by a second section to Hudson Bay where it ends at Fort Severn.
The Great Lakes Basin consists of the Great Lakes and the surrounding lands of the states of Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania, and Wisconsin in the United States, and the province of Ontario in Canada, whose direct surface runoff and watersheds form a large drainage basin that feeds into the lakes. It is generally considered to also include a small area around and beyond Wolfe Island, Ontario, at the east end of Lake Ontario, which does not directly drain into the Great Lakes, but into the Saint Lawrence River.
The Great Lakes-St. Lawrence Lowlands, or simply St. Lawrence Lowlands, is a physiographic region of Eastern Canada that comprises a section of southern Ontario bounded on the north by the Canadian Shield and by 3 of the Great Lakes — Lake Huron, Lake Erie and Lake Ontario — and extends along the St. Lawrence River to the Strait of Belle Isle and the Atlantic Ocean. The lowlands comprise three sub-regions that were created by intrusions from adjacent physiographic regions — the West Lowland, Central Lowland and East Lowland. The West Lowland includes the Niagara Escarpment, extending from the Niagara River to the Bruce Peninsula and Manitoulin Island. The Central Lowland stretches between the Ottawa River and the St. Lawrence River. The East Lowland includes Anticosti Island, Îles de Mingan, and extends to the Strait of Belle Isle.
The North York River is a river in the municipality of Dysart et al, Haliburton County in Central Ontario, Canada. It is in the southern extension of Algonquin Provincial Park, is in the Saint Lawrence River drainage basin, and is a left tributary of the York River.
Mississagi River Provincial Park is a protected area on the Mississagi River in Algoma and Sudbury Districts, Ontario, Canada. It has an Ontario Parks designation of Waterway Class. The park encompasses the river and lakes on the river from Mississagi Lake to Bark Lake, and further downstream to a point just above Ricky Island Lake, as well as portions of the upper Spanish River system.
Lake George is a lake in Chippewa County, Michigan, United States, and Algoma District, Northwestern Ontario, Canada, that lies between Sugar Island in Michigan on the west and the Ontario mainland on the east.
The Toronto waterway system comprises a series of natural and man-made watercourses in the Canadian city of Toronto. The city is dominated by a large river system spanning most of the city including the Don River, Etobicoke Creek, Highland Creek, Humber River, Mimico Creek and Rouge River.
The Ontario Peninsula is the southernmost part of the province of Ontario, and of Canada as a whole. It is bounded by Lake Huron to the west, Lake Ontario to the east, and Lake Erie to the south. At its tip, it is separated from Michigan by the Detroit and St. Clair Rivers, as well as Lake St. Clair. A secondary peninsula projects toward New York on the eastern side, ending at the Niagara River.
