 Space for the basin, the boathouses, the changing rooms and other buildings was obtained by demolishing many of the former pavilions and cutting in half the area taken by the artificial lake and the canals.In 1976, a fire destroyed the acrylic outer skin of Buckminster Fuller's dome, and the previous year the Ontario pavilion was lost due to a major fire.With the site falling into disrepair, and several pavilions left abandoned and vandalized, it began to resemble ruins of a futuristic city.
