Scarborough is the area that forms the eastern part of the City of Toronto, Ontario, Canada. It was a separate city for over 200 years, but has been part of the 'East District' of Toronto since 1998. The Scarborough name is still used by most local residents, and is recognized by Canada Post as a municipality name. Scarborough has characteristics of a suburb of old Toronto, but retains much of its own character and flavour. Certain neighbourhoods in Scarborough are popular destinations for new immigrants to Canada, who bring part of their own culture to that of Scarborough. Because of the topography of the Bluffs, the Rouge Valley and the other creeks and many minor tributaries, Scarborough is said to be the greenest and leafiest part of Toronto.
In 2001, Scarborough's population was 593,297, with a density of 3 160.9/km². A study based on census data between 1996 and 2001 shows that Scarborough's growth rate was more than 6%, the highest growth in Toronto. Its population is second to North York, but if this trend continues it should be the most populated district in Toronto by 2010.
Scarborough is home to an earthen cliff formation known as the Scarborough Bluffs. The Bluffs can be found along the shore of Lake Ontario, stretching about 14 km, and reaching heights of more than 60 m in places. They are part of a much larger formation known as the Iroquois Shoreline, most of which is located somewhat further inland. The Iroquois Shoreline marks the extent of a prehistoric lake, Glacial Lake Iroquois, whose level was quite a bit higher than present-day Lake Ontario's. It shrank in size at the close of the last ice age.
The Scarborough Town Centre is the largest commercial and entertainment hub east of Yonge Street in Toronto. It is located next to the Scarborough Civic Centre, Albert Campbell Square, Consilium Place and the Scarborough Centre. This area was developed as a city centre under the old City of Scarborough government. The Scarborough Walk of Fame is also located in the Town Centre, consisting of a number of plaques embedded in pavement to honour notable residents, past and current. The inaugural inductees included NBA player Jamaal Magloire, Olympic gold medallist Vicky Sunohara as well as 8 other prominent residents contributing to advances in medicine, arts, and community.
Compared to the City of Toronto as a whole, industry in Scarborough is similar in all labour force categories, save for manufacturing which is higher in Scarborough, and professional, scientific and technical services which are lower. The headquarters of Honda Canada Inc. are also located in Scarborough.
From McCowan RT station, to Midland RT station, centred on Scarborough Town Centre Mall and RT station is a small city centre, including a public square, government buildings, offices and in recent years many new condominiums, not to mention the Town Centre Mall. It has become one of Toronto's many new downtowns in the outer boroughs (another example is North York Centre in Uptown Toronto). See Scarborough City Centre.
Scarborough is the home of Ontario's first elevated rapid transit line, the Scarborough RT. The RT was built in 1985. It runs from Kennedy subway station to McCowan Avenue, just east of the Scarborough Town Centre. There are 6 stations along the RT route. The city is reviewing a number of replacement options, including turning it into a streetcar route or an extension of the City's subway system. The RT forms part of the public transit run by the Toronto Transit Commission, which also operates extensive bus routes, and three subway stations within Scarborough.
