Amalgamation of Toronto in the context of "Metropolitan Toronto"

Municipal annexation is the legal process by which a city or other municipality acquires land as its jurisdictional territory (as opposed to simply owning the land the way individuals do). The annexed land is typically not part of any other municipality. In the United States and Canada, however, annexation may also involve one polity absorbing another, usually an adjacent and smaller one, and usually by vote of the residents of both polities. For example, in 1872, the city Zanesville, Ohio annexed the adjacent community of Putnam, and in 1889, the city of Toronto annexed the adjacent town of Parkdale.

Toronto is the most populous city in Canada and the capital city of the Canadian province of Ontario. With a population of 2,794,356 in 2021, it is the fourth-most populous city in North America. The city is the anchor of the Golden Horseshoe, an urban agglomeration of 9,765,188 people (as of 2021) surrounding the western end of Lake Ontario, while the Greater Toronto Area proper had a 2021 population of 6,712,341. As of 2024, the Golden Horseshoe had an estimated population of 11,139,265 people while the census metropolitan area had an estimated population of 7,106,379. Toronto is an international centre of business, finance, arts, sports, and culture, and is recognized as one of the most multicultural and cosmopolitan cities in the world.

Indigenous peoples have inhabited the Toronto area, located on a broad sloping plateau interspersed with rivers, deep ravines, and urban forest, for more than 10,000 years. After the broadly disputed Toronto Purchase, when the Mississauga surrendered the area to the British Crown, the British established the town of York in 1793 and later designated it as the capital of Upper Canada. During the War of 1812, the town was captured by the United States after they won the Battle of York in 1813, after which it was largely burned down and plundered by the American troops. York was renamed and incorporated in 1834 as the City of Toronto. It was designated as the capital of the province of Ontario in 1867 during Canadian Confederation. The city proper has since expanded past its original limits through both annexation and amalgamation to its current area of 630.2 km (243.3 sq mi).

North York is a former township and city and is now one of the six administrative districts of Toronto, Ontario, Canada. It is located in the northern area of Toronto, centred around Yonge Street, north of Ontario Highway 401. It is bounded by York Region to the north at Steeles Avenue, (where it borders Vaughan) on the west by the Humber River, on the east by Victoria Park Avenue. Its southern boundary is erratic and corresponds to the northern boundaries of the former municipalities of Toronto: York, Old Toronto and East York. As of the 2016 Census, the district has a population of 644,685.

North York was created as a township in 1922 out of the northern part of the former township of York, a municipality that was located along the western border of the-then City of Toronto. Following its inclusion in Metropolitan Toronto in 1953, it was one of the fastest-growing parts of Greater Toronto due to its proximity to Toronto. It was declared a borough in 1967, and later became a city in 1979, attracting high-density residences, rapid transit, and a number of corporate headquarters in North York City Centre, its planned central business district. In 1998, North York was dissolved as part of the amalgamation which created the new City of Toronto. It has since become a secondary economic hub of the city outside Downtown Toronto.

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.

Scarborough (/ˈskɑːrbʌroʊ/; 2021 Census 629,941) is a district of Toronto, Ontario, Canada. It is situated in the eastern part of the City of Toronto. Its borders are Victoria Park Avenue to the west, Steeles Avenue and the city of Markham to the north, Rouge River and the city of Pickering to the east, and Lake Ontario to the south. Scarborough was named after the English town of Scarborough, North Yorkshire, inspired by its cliffs.

Scarborough, which was settled by Europeans in the 1790s, has grown from a collection of small rural villages and farms to become fully urbanized and diverse cultural community. Incorporated in 1850 as a township, the district became part of Metropolitan Toronto in 1953 and was reconstituted as a borough in 1967. The borough rapidly developed as a suburb of Toronto over the next decade and became a city in 1983. In 1998, the city and the rest of Metropolitan Toronto were amalgamated into the present city of Toronto. The Scarborough Civic Centre – the former city's last seat of government – now houses offices of the municipal government of Toronto.

York is a district and former city within Toronto, Ontario, Canada. It is located northwest of Old Toronto, southwest of North York and east of the Humber River.

Originally formed as York Township, it encompassed the southern section of York County. It was split several times, creating East York and North York. In 1953, it became part of the Metropolitan Toronto federation. It absorbed several municipalities, including Lambton Mills and Weston and was eventually known as the City of York. In 1998, it was dissolved along with Metro Toronto and its constituent municipalities, amalgamated to form the current City of Toronto.

Old Toronto is the part of Toronto, Ontario, Canada, that corresponds to the boundaries of the City of Toronto prior to 1998. It was incorporated as a city in 1834, after being known as the town of York, and being part of York County. Toronto periodically grew in size by annexing adjacent land and municipalities.

In 1954, the City of Toronto and the surrounding suburban towns and townships of York County were joined in a federation known as the Municipality of Metropolitan Toronto (Metro). Later, the lower-tier city annexed two towns until it reached its final boundaries in 1967. In 1998, the municipalities of Metro Toronto were amalgamated into the present-day single-tier City of Toronto, which continues legally from the predecessor City of Toronto, although the by-laws of each municipality remained in force.
