Toronto City Council has approved 23 Toronto Street, a transformative new mixed-use development in the heart of downtown Toronto.

Rising approximately 300 metres across 91 storeys, the project will introduce a new skyline-defining tower while carefully retaining and revitalising four significant heritage buildings, including Toronto’s first courthouse. WW+P is serving as planner, architect, and landscape architect for the development.

Located within Toronto’s historic core, the project represents a major milestone in the evolution of the city’s downtown; balancing intensification, heritage conservation, and public realm enhancement through an integrated design approach. The project creates a renewed relationship with Courthouse Square Park through fronting retail spaces and a new activated mews connecting Adelaide Street to the Square.

The approval marks years of collaboration between the consultant team, City staff, stakeholders, and community members to advance a project that both respects the site’s historic significance and contributes meaningfully to Toronto’s continued growth.

WW+P collaborated closely with an accomplished consultant team including ERA Architects, BA Consulting Group Ltd., Norm Li, Counterpoint Engineering, Introba, Entuitive, S2S Environmental Inc., Kuntz Forestry Consulting Inc., and RWDI.

The project is poised to become a significant addition to Toronto’s skyline while reinforcing the importance of preserving and reinvigorating the city’s architectural heritage.

Projects like 23 Toronto Street ask you to think carefully about how a city evolves over time. There’s a real responsibility — and opportunity — in bringing new density into the downtown core while ensuring the layers of history already embedded in the site continue to be part of the city’s story. We’re excited to see this project move forward.
