Toronto's Next Architectural Landmark

One Delisle

Project Overview

About One Delisle

The first residential building in Canada designed by visionary architect, Jeanne Gang.

One Delisle is a vision for the future of high-rise living. The residential tower marries environmental and civic needs with architectural ingenuity.

Rising from a square base at street level, One Delisle spirals to become a 16-sided circular tower with generous outdoor spaces throughout the building. The building’s terraces and balconies unite the energy of Toronto with the calm of the surrounding natural landscape and ravines.

Project Highlights

Iconic Architecture

Designed by one of the world’s most innovative design minds, One Delisle will be unlike any building before it. An iconic piece of architecture, a new model for sustainable growth, and an exemplar of how to build a stronger community.

Unique Location

Yonge and St. Clair is rich in history and home to some of Toronto’s most luxurious residences, renowned schools, shops and restaurants, and green spaces, forested trails, ravines, and Toronto’s oldest reservoir.

Natural Urban Living

The residential condominium building unites Toronto’s urban vibrancy with the tranquillity of the nearby forested ravine system. The rhythmic exterior is comprised of nesting forms that create a variety of usable green outdoor spaces.

What They Say

“Our plan with Yonge and St. Clair is to be here forever. When you’re thinking that way it changes your decision-making. We want to make a difference in this city, and we’re here because we want to do  something that is remarkable.”

Lucas Manuel

Partner at SLATE

“A theme that always reoccurs in our work is pattern and rhythm, because architecture is an unmoving, monumental kind of art. And these patterns can contribute to how the building performs”


Jeanne Gang

Lead Architect

“Slate Asset Management has spent years working with world-leading architects, planners, and city builders to realize One Delisle. A project that will redefine Yonge & St. Clair and forever change the Toronto skyline”
