Lake in Ontario, Canada

Lake Simcoe is a lake in southern Ontario, Canada, the fourth largest lake wholly in the province, after Lake Nipigon, Lac Seul, and Lake Nipissing. At the time of the first European contact in the 17th century, the lake was called Ouentironk ("Beautiful Water") by the native Wendat/Ouendat (Huron) people. It was also known as Lake Taronto until it was renamed by John Graves Simcoe, the first Lieutenant Governor of Upper Canada, in memory of his father, Captain John Simcoe of the Royal Navy. In Anishinaabemowin, the historical language of the First Nations living around this lake, namely Anishinaabek of Rama and Georgina Island First Nations, the lake is called Zhooniyaang zaaga'igan, meaning "Silver Lake".

Lake Simcoe's name was given by John Graves Simcoe in 1793 in memory of his father, Captain John Simcoe. Captain Simcoe was born on 28 November 1710, in Staindrop, in County Durham, northeast England, and served as an officer in the Royal Navy, dying of pneumonia aboard his ship, HMS Pembroke, on 15 May 1759. Historically, at the time of the first European contact in the 17th century, the lake was called Ouentironk ("Beautiful Water") by the Wyandot (Huron) natives; The Wyandot name for the lake was rendered as Wentaron in European sources up until the 20th century. A 1675 map by Pierre Raffeix referred to the lake with the French term Lac Taronto and a 1687 map by Lahontan called it Lake Taronto, while the name Tarontos Lac appeared on a 1678 map of New France by cartographer Jean Baptiste Louis Franquelin. The term Taranto refers to an Iroquoian expression meaning gateway or pass. Taronto had originally referred to The Narrows, a channel of water through which Lake Simcoe discharges into Lake Couchiching. (Natural Resources Canada gives a related translation: "it originated as the Mohawk phrase tkaronto, which means "where there are trees standing in the water". According to several Mohawk speakers and aboriginal language expert John Steckley. Mohawks used the phrase to describe The Narrows, where Hurons and other natives drove stakes into the water to create fish weirs. Since then, many subsequent mapmakers adopted this name for it, though cartographer Vincenzo Coronelli is thought to have introduced the more commonly used spelling of Toronto in a map he created in 1695. The name 'Toronto' found its way to the current city through its use in the name for the Toronto Carrying Place Trail (or Toronto Passage), a portage running between Lake Ontario and Georgian Bay, that passed through Lake Toronto, which in turn was used as the name for an early French fort located at the foot of the Toronto Passage, on Lake Ontario. The Severn River, its outlet stream, was once called 'Rivière de Toronto' which flows into Georgian Bay's Severn Sound, then called the 'Baie de Toronto'. Later French traders referred to it as Lac aux Claies, meaning "Lake of Grids (or Trellises)" in reference to the Huron fishing weirs in the lake. It was known by this name until the beginnings of Upper Canada, when it was renamed to Lake Simcoe.

The lake is bordered by Simcoe County, Durham Region, and York Region. The city of Barrie is located on Kempenfelt Bay, and Orillia is located at the entrance to Lake Couchiching. The watershed draining into the lake contains a population of roughly half a million people, including the northern portion of the Greater Toronto Area (GTA). The town of Georgina lies along the entire south shore of Lake Simcoe and consists of smaller residential towns and communities, including Keswick on Cook's Bay, Sutton, Jackson's Point, Pefferlaw, and Udora. The town of Innisfil occupies the western shore south of Barrie and north of Bradford. Eastside Simcoe includes the towns of Beaverton, Brechin and Lagoon City. Lake Couchiching was at one time thought of as a third bay of Simcoe, known as the Bristol Channel; however, the narrows between the two bodies of water separate them enough to consider this to be another lake. The narrows, known as "where trees stand in the water", an interpretation of the word 'Toronto', was an important fishing point for the First Nations peoples who lived in the area, and the Mohawk term toran ten eventually gave its name to Toronto by way of the portage route running south from that point, the Toronto Carrying Place Trail. Radiocarbon dating of surviving stakes reveals that the weirs at The Narrows were in use more than 4,000 years ago. The meaning of "where trees stand in the water", is likely to have originated from Huron practice of driving stakes into the channel sediments to corral fish. Fresh cut saplings placed in the water and sediments would have sprouted branches and leaves, persisting for some time, leading to a place "where trees stand in the water".

Lake Simcoe contains a large island, Georgina, which along with Snake Island and Fox Island forms the reserve of the Chippewas of Georgina Island First Nation. The lake is dotted with several smaller islands, including Thorah Island (a cottage destination), Strawberry Island, Snake Island, Helmers Island and Fox Island. Pope John Paul II stayed on Strawberry Island for four days just before World Youth Day 2002 in Toronto. Before the completion of the Trent Severn Waterway, the water level on Lake Simcoe was quite low enabling residents to cross in wagons or walk in ankle deep water to the mainland. However, when it was completed, the water table increased by several feet. Grape Island on the north end the lake is located off of Orillia. To the east of Grape Island is Goffatt Island, a small and private island located within Ramara. Georgina, Snake and Fox Islands are within York Region, Thorah is within Durham Region, where as Strawberry Island and Helmers Island are privately owned but within the boundaries of Ramara in Simcoe County. Grape is within Orillia and Goffatt is within Ramara with both owned privately by residents.

The lake is about long, wide and in area.

When a lake is healthy, cold water fish such as lake trout, herring, and whitefish are abundant and active. It is sometimes known as Canada's ice fishing capital.

Lake Simcoe has been victim to significant eutrophication. Lake Simcoe has seen a dramatic decline in some fish species, along with an increase in algae blooms and aquatic weed growth. Phosphorus emissions from both urban and rural sources have upset the lake's ecosystem and fostered excessive aquatic plant growth, raising water temperatures, and decreasing oxygen levels, thereby rendering limited breeding grounds inhospitable. Lake Simcoe has been victim to zebra mussel, purple loosestrife, black crappie, spiny water flea, round goby, rusty crayfish and Eurasian milfoil invasions. The zebra mussel, which arrived in North American waters in 1985, originated in the Black Sea and Caspian Sea area and is thought to have been brought to North America in the ballast of foreign freighters. Zebra mussels are particularly harmful to Lake Simcoe because they increase the clarity of the water allowing sunlight to penetrate to the bottom of the lake, where more algae and aquatic weeds can grow, accelerating the eutrophication process. Several initiatives, such as the Lake Simcoe Environmental Management Strategy (LSEMS), the Lake Simcoe Conservation Foundation, and the Lake Simcoe Region Conservation Authority, are making efforts to rectify some of the lake's environmental woes. A local activist group, The Ladies of the Lake, are using the $250,000 they raised from the sale of a nude picture calendar to rally government, business, the school system, and the local citizenry to rescue the lake. Several towns and communities on the lakeshore depend on Lake Simcoe for their drinking water. The Region of York is currently finalizing plans for a sewage treatment plant to be constructed on the shores of Lake Simcoe to be located on the Holland River in Cook's Bay. This plant's purpose is to support intensification of development in the Lake Simcoe watershed.

The lake has little commercial activity, but sees many recreational uses. In the winter, it freezes over completely and hosts a number of ice fishing competitions, making it one of the most intensely fished lakes in Ontario. However, claims that it is one of the world's largest lakes that freeze over completely in winter are pure speculation, and, in fact, spurious; Canada alone has a large number of lakes of the same size or larger that do the same. In the summer, fishing is still an attraction; however, there are also a number of poker runs, jet skiing, and other boating events. The lake is surrounded with summer cottages leading to heavy recreational and boating use in summer. There are a number of beaches which attract visitors from the greater Toronto area, as Lake Simcoe has a reputation for cleaner and warmer water than nearby Lake Ontario beaches. Many of the beaches are used for kite surfing as well. Willow Beach in Georgina on the south shore is one of the largest and most popular public beaches on Lake Simcoe. There are seven yacht clubs (sailing) around the lake, which host a number of regattas, and an active sailing community exists on the lake. The lake also forms part of the Trent–Severn Waterway system that links Lake Ontario and Georgian Bay/Lake Huron. Lake Simcoe is also well known for its scuba diving. The ship J. C. Morrison sank in 1857 and is a great dive site off Centennial Beach. There are also a number of other popular scuba diving entrance points popular among fresh water divers. Kempenfelt Bay is the most popular for scuba divers as it is the deepest. Visibility ranges from over 30 feet to almost zero.

Ontario Provincial Police, South Simcoe Police Service, York Regional Police, Durham Regional Police, and Barrie Police have marine units that patrol on the waters of the lake. Georgina Island Police patrol on Georgina, Fox and Snake Islands with some capability to respond to marine needs off these islands. As part of Orillia, Grape Island is policed by the OPP.
