[5] Toronto-born Frank Gehry was also the main architect behind Toronto's Art Gallery of Ontario building.

The original plan, released in 2012, was for three towers and included demolition of the Mirvish-owned Princess of Wales Theatre and some early 1900s-era heritage buildings.

After consultation with the City of Toronto government, the project plan was changed to two towers, will spare the theatre, and preserve elements of the heritage buildings.

In October 2017, Mirvish sold the project to Great Gulf Corporation, builders of the One Bloor tower in Toronto, which will develop it.

The updated designs also excluded a planned hotel that had been shown on previous iterations as occupying floors 10-20 of the west tower.
