The massive CIBC Square office complex in downtown Toronto is now complete, following the construction of the second 50-storey second tower in the two-building campus spanning the Union Station rail corridor.

Architecture firm WilkinsonEyre, working with architect of record Adamson Associates for developers La Caisse and Hines, announced the completion of the second phase of the mixed-use development in Toronto’s financial district.

The completion of 141 Bay St. marks the culmination of WilkinsonEyre’s master plan for the site, building on the first phase at 81 Bay St. to create a transit-connected commercial campus. The development features two 250-metre office towers linked by a one-acre elevated sky park above active rail infrastructure.

The sky park, developed with landscape architects Public Work, is scheduled to open later this year and will offer year-round public programming. The park includes gardens, walking paths, gathering spaces and outdoor amenities.

“CIBC Square presented an extraordinary opportunity to rethink how large commercial developments can contribute to the life of the city,” said Dominic Bettison, director at WilkinsonEyre in a statement provided to media outlets. “Rather than treating infrastructure as a barrier, the project embraces it as an organizing element that connects transit, landscape, workplace and public space into a seamless urban experience. The development creates a new gateway into downtown Toronto while extending the energy of the financial district toward the waterfront.”

Built across three linked sites totalling eight acres, the development was delivered in two phases. The first tower, at 81 Bay St., rises 54 storeys and includes office and trading floors, conference facilities, retail space, restaurants and transit infrastructure. The newly completed 141 Bay St. tower completes the campus on the north side of the rail corridor.

Both towers feature folded glazed façades that create a repeating diamond pattern every 10 floors. The campus also incorporates restaurants, fitness facilities, conference and event spaces, public art installations and green public plazas.

The project was designed to achieve LEED and WELL Platinum certifications, with a focus on daylight access, air quality, occupant wellness and energy efficiency.

La Caisse and Hines, the property’s owners, announced in February that the towers had received full lease-up.
