John Graves Simcoe in the context of "London, Ontario"

Markham (/ˈmɑːrkəm/) is a city in York Region, Ontario, Canada. It is approximately 30 km (19 mi) northeast of Downtown Toronto. In the 2021 Census, Markham had a population of 338,503, which ranked it the largest in York Region, fourth largest in the Greater Toronto Area (GTA), and 16th largest in Canada.

The city gained its name from the first Lieutenant-Governor of Upper Canada, John Graves Simcoe (in office 1791–1796), who named the area after his friend, William Markham, the Archbishop of York from 1776 to 1807.

Yonge Street (/jʌŋ/ YUNG) is a major arterial route in the Canadian province of Ontario connecting the shores of Lake Ontario in Toronto to Lake Simcoe, a gateway to the Upper Great Lakes. Ontario's first colonial administrator, John Graves Simcoe, named the street for his friend Sir George Yonge.

Once the southernmost leg of provincial Highway 11, linking the provincial capital with northern Ontario, Yonge Street has been referred to as "Main Street Ontario". Until 1999, the Guinness Book of World Records repeated the popular misconception that Yonge Street was 1,896 km (1,178 mi) long, making it the longest street in the world; this was due to a conflation of Yonge Street with the rest of Ontario's Highway 11. The street (including the Bradford-to-Barrie extension) is only 86 kilometres (53 mi) long. Due to provincial downgrading in the 1990s, no section of Yonge Street is marked as a provincial highway.

York was a town and the second capital of the colony of Upper Canada. It is the predecessor to the old city of Toronto (1834–1998). It was established in 1793 by Lieutenant-Governor John Graves Simcoe as a "temporary" location for the capital of Upper Canada, while he made plans to build a capital near today's London, Ontario. Simcoe renamed the location York after Prince Frederick, Duke of York and Albany, George III's second son. Simcoe gave up his plan to build a capital at London, and York became the permanent capital of Upper Canada on February 1, 1796. That year Simcoe returned to Britain and was temporarily replaced by Peter Russell.

The original townsite was a compact ten blocks near the mouth of the Don River and a garrison was built at the channel to Toronto Harbour. Government buildings and a law court were established. Yonge Street was built, connecting York to the Holland River to the north. To the east, Kingston Road was built to the mouth of the Trent River. In 1797, the town site was expanded to the west to allow for public buildings and expansion. One of the new area's public functions, a public market, was started in 1803. It continues today as St. Lawrence Market.

The name of Toronto has a history distinct from that of the city itself. Originally, the term "Tkaronto" referred to a channel of water between Lake Simcoe and Lake Couchiching, at what is now the city of Orillia, on maps as early as 1675 but in time the name passed southward, and was eventually applied to a new fort at the mouth of the Humber River. Fort Toronto was the first European settlement in the area, and lent its name to what became the city of Toronto.

John Graves Simcoe identified the area as a strategic location to base a new capital for Upper Canada, believing Newark to be susceptible to American invasion. A garrison was established at Garrison Creek, on the western entrance to the docks of Toronto Harbour, in 1793; this later became Fort York. The settlement it defended was renamed York on August 26, 1793, as Simcoe favoured English names over those of First Nations languages, in honour of Prince Frederick, Duke of York. Residents petitioned to change the name back to Toronto, and in 1834 the city was incorporated with its original name. The name York lived on through the name of York County (which was later split into Metropolitan Toronto and York Region), and continues to live on through the names of several districts within the city, including Yorkville, East York, North York, and York the last three being suburbs that were formally amalgamated into the "megacity" of Toronto on January 1, 1998.

Lake Simcoe is a lake in southern Ontario, Canada, the fourth-largest lake wholly within 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".

Sir George Yonge, 5th Baronet, KCB, PC, FRS (17 July 1731 – 25 September 1812) was a British politician and colonial administrator who served as Secretary at War from 1782 to 1783 and again from 1783 to 1794. He succeeded to his father's baronetcy in 1755, which became extinct when he died without children. Yonge is remembered by, among other things, the name of Yonge Street, a principal road in what is now Toronto, Canada, so named in 1793 by the Lieutenant-Governor of Upper Canada, John Graves Simcoe.

Fort York is an early 19th-century military fortification in the Fort York neighbourhood of Toronto, Ontario, Canada. The fort housed members of the British and Canadian militaries and defended the entrance to Toronto Harbour. The fort features stone-lined earthwork walls and eight historical buildings within them, including two blockhouses. The fort forms a part of Fort York National Historic Site, a 16.6 ha (41-acre) site that includes the fort, Garrison Common, military cemeteries, and a visitor centre.

The fort originated from a garrison established by John Graves Simcoe in 1793. Anglo-American tensions resulted in the fort being further fortified and designated as an official British Army post in 1798. The original fort was destroyed by American forces following the Battle of York in April 1813. Work to rebuild the fort began later in 1813 over the remains of the old fort and was completed in 1815. The rebuilt fort served as a military hospital for the remainder of the War of 1812, although it briefly saw action against an American naval vessel in August 1814.
