Ontario Science Centre

The Ontario Science Centre is a science museum in Toronto, Ontario, Canada, near the Don Valley Parkway about 11 kilometres northeast of downtown on Don Mills Road just south of Eglinton Avenue East in the former city of North York. It is built down the side of a wooded ravine formed by one branch of the Don River located in Flemingdon Park.
Planning for the Science Centre started in 1961 during Toronto's massive expansion of the late 1950s and 1960s. In 1964, Toronto architect Raymond Moriyama was hired to design the site. The Brutalist design, which consists of three main buildings connected by a series of bridges and escalators, follows the natural contours of the Don River ravine, into which the Centre descends. Construction started in 1966 with plans to make it a part of the city's 1967 Canadian Centennial celebrations. It was first officially named the "Centennial Centre of Science and Technology". However construction was not complete in 1967, and the Science Centre did not open to the public until two years later, on September 26, 1969.
