CIBC SQUARE

The total development will be constructed in two phases to provide Grade A office and amenity space. The first phase, 81 Bay Street, is a 54-storey tower and associated podium, which includes approximately 18,580m² of trading floors and amenity spaces including a food hall, retail, conference facilities and the new bus terminal. A new one-acre landscaped sky park spans the rail corridor connecting 81 Bay Street south of the rail corridor to 141 Bay Street.

Both towers feature a lightly folded glazed façade, creating a diamond pattern that repeats every ten storeys, adding a vertical scale and modulation contrasting with the surrounding buildings. The construction of 81 Bay Street began in June 2017 and was completed in 2021. The overall development, with CIBC as the anchor tenant, is due for completion by 2024.

The lobbies of both towers provide spectacularly grand spaces that are a first for the Toronto market. The ambition to connect each tower’s lobby and lift access to the elevated sky park means each lobby is 25m high, with upper sky lobbies giving direct access to the park. The rear wall is clad in slabs of vein-cut travertine fabricated to generate a super-scaled three-dimensional relief, itself composed of a series of repeated triangulated elements.

These triangular forms are part of the underlying geometric design language running through the building. Esteemed Toronto-based painter Steve Driscoll was commissioned to make a site-specific artwork bringing Canada's northern boreal forest into the building.

 Integrated into the recess of the six elevator bays and visible from the street, softly backlit glass panels 11m high depict tall trees in a lakeside setting, realised in rich colours and deep shadow.
