The Ontario Tower is a luxury high-rise residential development in London's Docklands. It was built by the Ballymore construction company, as part of a wider scheme in New Providence Wharf to provide new executive housing to meet changing demand in the Docklands area. 'Ontario' was designed by the architects who created landmarks such as Chicago's Willis Tower.
The Ontario Tower is a distinct landmark of the London Skyline with its blue LED rimmed elliptical top. The 29-storey project was completed in the Autumn of 2007, and was the tallest building in London solely designed for executive residential use, at 104 metres tall until Ballymore completed Pan Peninsula just a short distance away on Marsh Wall. It is expected to be joined by a much taller neighbour (Quebec Tower) directly next to it.
