Canary Wharf is an area of London, England, located near the Isle of Dogs in the London Borough of Tower Hamlets. Canary Wharf is defined by the Greater London Authority as being part of London's central business district, alongside Central London. With the City of London, it constitutes one of the main financial centres in the United Kingdom and the world, containing many high-rise buildings including the third-tallest in the UK, One Canada Square, which opened on 26 August 1991.

Developed on the site of the former West India Docks, Canary Wharf contains around 16,000,000 sq ft (1,500,000 sq m) of office and retail space. It has many open areas, including Canada Square, Cabot Square and Westferry Circus. Together with Heron Quays and Wood Wharf, it forms the Canary Wharf Estate, around 97 acres (39 ha) in area.

After the 1960s, when cargo became containerized, port industry began to decline, leading to all the docks being closed by 1980. After the docks closed in 1980, the British Government adopted policies to stimulate redevelopment of the area, including the creation of the London Docklands Development Corporation (LDDC) in 1981 and the granting of Urban Enterprise Zone status to the Isle of Dogs in 1982.

The Canary Wharf of today began when Michael von Clemm, former chairman of Credit Suisse First Boston (CSFB), came up with the idea to convert Canary Wharf into a back office. Further discussions with G Ware Travelstead led to proposals for a new business district and included the LDDC developing an inexpensive light metro scheme, the Docklands Light Railway, to make use of a large amount of redundant railway infrastructure and to improve access.

The project was sold to the Canadian company Olympia & York and construction began in 1988, master-planned by Skidmore, Owings & Merrill with Yorke Rosenberg Mardall as their UK advisors, and subsequently by Koetter Kim. The first buildings were completed in 1991, including One Canada Square, which became the UK's tallest building at the time and a symbol of the regeneration of Docklands. By the time it opened, the London commercial property market had collapsed, and Olympia and York Canary Wharf Limited filed for bankruptcy in May 1992.

Initially, the City of London saw Canary Wharf as an existential threat. It modified its planning laws to expand the provision of new offices in the City of London, for example, creating offices above railway stations (Blackfriars) and roads (Alban Gate). The resulting oversupply of office space contributed to the failure of the Canary Wharf project.
