The $3.5 billion investment in Toronto's transit-linked commercial campus

WilkinsonEyre has completed the second phase of CIBC SQUARE , a major mixed-use development in Toronto's financial district, with a total investment of $3.5 billion.. Designed in collaboration with architect of record Adamson Associates for developers La Caisse and Hines, the completion of 141 Bay Street marks the culmination of WilkinsonEyre's broader masterplan for the site.

The development introduces a pair of 250-metre commercial towers linked by a one-acre elevated sky park that spans active rail infrastructure. The sky park, developed in collaboration with landscape architects Public Work, is due to open later this year and will offer year-round programming to the public.

Setting a new benchmark for transit-oriented development

The project presented an extraordinary opportunity to rethink how large commercial developments can contribute to the life of the city, according to Dominic Bettison, director at WilkinsonEyre. 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. CIBC SQUARE was built across three linked sites totaling eight acres, with the sky park forming the centerpiece of the masterplan.

Embracing sustainability and public space

The project's ambitious sustainability goals include LEED and WELL Platinum certifications , prioritizing daylight access, air quality, occupant wellness, and energy efficiency. The development employs advanced building systems such as high-performance glazing, efficient HVAC, and green roofs to minimize its environmental footprint.

The sky park, which is due to open later this year, will offer year-round programming to the public, including gardens, walking paths, gathering spaces, and outdoor amenities above active rail lines. the design ensures that the park serves as a communal hub, hosting events, performances, and seasonal activities that draw both office workers and the general public.
