Cinesphere is the world's first permanent IMAX movie theatre, located on the grounds of Ontario Place in Toronto, Ontario, Canada. Constructed in 1971, it is the largest IMAX theatre in Ontario. The theatre has both IMAX 70mm and IMAX with Laser projection systems. The theatre is considered a building of heritage value and shows movies each weekend. It is owned by the Government of Ontario.
Cinesphere's is a 35 metres (115 ft) wide triodetic-domed structure, akin to a geodesic dome, with a 62-foot (18.9 m) outer radius, and a 56-foot (17.1 m) inner radius, supported by prefabricated steel and aluminium alloy tubes. Eberhard Zeidler, who also designed the "Pods" of Ontario Place, also designed Cinesphere. Its screen is 80 feet (24 m) wide by 60 feet (18 m) high. Its seating capacity was originally 752, but this was reduced after a renovation for 3D projection in 2011 to 614. The building is surrounded by a moat, and the entrance area is through doorways on the east side connected to the Ontario Place pod bridges and staircases to the Ontario Place West Island. Exiting is done through doorways leading to ramps over the moat to the West Island. The seating is stadium-style seating with no obstructions. The Cinesphere is wheelchair accessible.
Graeme Ferguson's North of Superior was the first film commissioned for and screened at Cinesphere at its May 1971 grand opening. In 1991, the sound system was upgraded adding digital capabilities. In 2011, the original projection system was replaced with an IMAX GT 3D system and new NEXIOS playback system. In celebration of its 40th Anniversary in 2011, the theatre closed for six months to undergo extensive renovations. On February 1, 2012, the province of Ontario announced that Cinesphere would close while Ontario Place is under renovation. On July 31, 2014, the province announced plans to revitalize the area as an urban park with the Cinesphere and pods retained. During the renovations, the theatre was used as a testbed for IMAX's new laser projection system. In 2014, the province designated Cinesphere as a structure of Cultural Heritage Value.
In 2017, a new projection system "IMAX with Laser" was installed in addition to its 70mm film projector. In September 2017, Cinesphere temporarily re-opened for special screenings of Dunkirk (2017) and North of Superior (1971) as part of the 2017 Toronto International Film Festival. In October 2017, it was announced that it would reopen as a permanent theatre. It reopened on November 3, 2017.
