The venue is located on three artificial landscaped islands just off-shore in Lake Ontario, south of Exhibition Place, and southwest of Downtown Toronto
It opened on May 22, 1971, and operated as a theme park centered around Ontario themes and family attractions until 2012 when the Government of Ontario announced that it would close for redevelopment
It has since reopened as a park without admission but without several of the old attractions
The Government of Ontario is currently considering further redevelopment of the site
Since the closure as a theme park, several of the venue's facilities have remained open, once reopened, and one section was redeveloped
The Budweiser Stage operates during the summer season
The Cinesphere, the original IMAX theatre, reopened with new projection equipment and shows films regularly
On the East Island, Trillium Park and the William Davis Trail opened in 2017
A marina, sheltered by three sunken lake freighters operates seasonally at the site
The exhibit "pods", several pavilions suspended above a lagoon, have remained closed after the closure of the Atlantis event facility
While much of the West Island's facilities are permanantly closed, some of the natural spaces are now being used for recreation
Occasionally special events are hosted in the west island village.
