CIBC SQUARE - Tower & Podium
The CIBC SQUARE Tower is a commercial space that offers 54-storeys of modern offices and collaborative spaces for working professionals in downtown Toronto. Located at 81 Bay Street, the CIBC SQUARE Tower is engineered to LEED Platinum specifications and is Walters fourth LEED certified office tower.
The CIBC SQUARE Podium is a seven-level structure that features retail spaces, a food hall, as well as an integrated Metrolinx GO bus terminal. Additionally, on the fourth level, it provides access to the overbuild—a one-acre elevated park known as the Sky Park—which spans the rail corridor and seamlessly connects the two towers (81 Bay St. and 141 Bay St.).
- The development integrates a 54 storey, 145,000 m2 office tower with an elevated public park above the Union Station rail corridor
- A PATH bridge, fabricated and erected by Walters Group, connects the complex at 81 Bay St. to the Scotiabank Arena
- Approximately 15,000T of steel
Walters Group supplied the engineering, detailing, fabrication and erection of approximately 15,000 tons of structural steel and decking for CIBC SQUARE Toronto (81 Bay Street), podium, overbuild park and Scotiabank Arena Pedestrian Bridge.
Construction took place in a highly congested downtown Toronto site, requiring close coordination between the Walters Group team, the general contractor, and multiple trades. This was especially critical as surrounding traffic remained active throughout the steel erection process, demanding careful planning and execution to maintain safety and minimize disruption.
A defining feature of the CIBC SQUARE tower was the AESS canopy, designed with cantilevered exterior corners. Achieving the precise final elevation once the glass was installed required a specialized heat-cambering process completed in our shop, along with carefully detailed connections to maintain a clean, seamless appearance.
Also at the podium level, the integration of the GO Bus Terminal required long-span, column-free spaces supported by large structural trusses within a tightly constrained footprint.
For the top of the tower, the crown featured an intricate, non-repetitive geometry. This demanded precise modeling and coordination to accommodate shifting connections and hundreds of façade attachment points.
