The approximately 3,000,000 square feet (280,000 m2) complex will consist of two towers to be completed in two phases.[7]

The 49 storey south tower (81 Bay Street) [8] was completed first, built on the site of a former parking lot opposite the Scotiabank Arena. This tower includes the Union Station Bus Terminal for regional GO Transit and inter-city bus services, replacing the former terminal on Bay Street. A pedestrian skybridge links the complex to Scotiabank Arena and Union Station, expanding the PATH walkway system further south below the railway corridor – to the One Yonge Street complex and ultimately to the under-development Sugar Wharf project on the LCBO lands farther east.[9] Attached to the tower is a four-storey podium housing CIBC's flagship retail bank branch.[10]

The 50 storey north tower (141 Bay Street) will be built on the site of the former GO Transit bus terminal, located behind the Dominion Public Building. The north tower is currently under construction and scheduled for completion in 2025.[7]

At the fourth floor level, there is a one-acre, publicly accessible park, elevated over the railway corridor, with year-round activation and varied topography: slopes and hills, horticulture, gardens, shade groves, balconies, and vista areas.[6][11]

The fourth floor level also includes an operational food hall at 81 Bay Street, branded TABLE Fare + Social[12] and a future food and beverage offering at 141 Bay Street.

The overall complex was designed by British architects WilkinsonEyre, and Adamson Associates of Toronto.[13]
