Ontario Place is a 155-acre tourist attraction located on the Lake Ontario shoreline in Toronto. Operated by the Province of Ontario, the park opened on 22 May 1971. A highlight of the $29-million project was the Cinesphere, the world’s first permanent IMAX theatre. Aside from Atlantis (an event space), the marina and its music venues, the provincial government closed Ontario Place between 2012 and 2017 to save money. While many of the park’s attractions permanently closed during this period, others, such as the Cinesphere, reopened. The provincial government is working with various developers to further reimagine the space.
