The second tower, Bay Adelaide East, entails a floor area of 91,045 square metres (980,000 sq ft) and a height of 44 storeys.

The third tower, Bay Adelaide North entails a floor area of approximately 46,450 square metres (500,000 sq ft) and a height of 28 to 32 storeys.

Cloud Gardens, a 0.24-hectare (0.59-acre) public park, is located immediately to the east of the Bay Adelaide North site on land conveyed to the City of Toronto as a condition of the original development approvals for the complex.

It was to have cost almost a billion dollars, and was the last of a series of construction projects in downtown Toronto launched in the boom years of the 1980s, when a number of massive towers were built nearby, such as Scotia Plaza.

All that was completed was the underground parking garage and several storeys of the concrete service shaft that stood from 1991 onwards, as a monument to the failed project in downtown Toronto.

Brookfield was committed to completing the structure to a smaller height of either 40 or 50 storeys, but later that year the economy again soured and the project remained on hiatus.

Brookfield Properties had signed KPMG and Goodmans as anchor tenants for the first tower, Bay Adelaide West, with Fasken Martineau and Heenan Blaikie also taking up residence in the building.

It is also featured extensively on TV show Suits, being the fictional head office of the law firm Pearson Specter Litt.

In June 2012, Brookfield announced that it planned to commence construction of Bay Adelaide East at 44 storeys and 91,045 square metres (980,000 sq ft), with Deloitte as the anchor tenant.

In August 2018, Brookfield announced that it planned to commence construction of Bay Adelaide North at 32 storeys and 76,180 square metres (820,000 sq ft), with Scotiabank as the anchor tenant.
