Canada Water was originally intended to be a stop on the aborted
Fleet line Extension to
Thamesmead. The extension was never built, but Canada Water became the only projected Fleet line Extension station to be realised on the
Jubilee Line Extension. The station is a wholly new building on a derelict site formerly occupied by Albion Dock, part of the old
Surrey Commercial Docks. Construction began in 1995. It proved extremely challenging, requiring the excavation (by
cut-and-cover) of a void long, wide and deep. The building of the
East London line station required a separate slot at right angles, long, deep and tapering in width, incorporating a Victorian railway tunnel. Construction was complicated by the high water table on the site, which is located on the Thames flood plain; extensive deep-well dewatering was required to lower the water table before the enclosure to the excavations could be built. A total of of spoil had to be excavated. An additional complication was the location of the excavation site, near the foundations of two existing 22-storey tower blocks and the northern end of the former Canada Dock, now the ornamental lake
Canada Water. The section of East London line running through the station was completely reconstructed, with the 19th-century brick railway tunnel being dismantled and the track relaid over a new structure bridging the Jubilee line tracks below. As the East London line had to be closed for this work, London Underground took the opportunity to carry out other remedial works such as repairs to the
Thames Tunnel, a short distance to the north. It was opened on 19 August 1999, served initially by East London line trains. The Jubilee line passenger service from the station began on 17 September that year. In 2012, it was used as a filming location for part of the pilot episode of the
BBC/
Cinemax British-American spy drama,
Hunted (TV series). Canada Water was the first station to receive external sponsorship;
Nestlé sponsored the station on the day of the
2015 London Marathon, and roundels in the station were edited to advertise Nestlé's
Buxton Water. The one-day sponsorship was part of a plan to increase
Transport for London's non-fare revenue, costing Nestlé £110,000. ==Architecture==
