One Delisle is an upcoming condominium development located at the north-west side of Yonge St and St Clair Ave. A collaboration between internationally acclaimed architect Jeanne Gang and Slate Asset Management, this one-of-a-kind tower is destined to become an iconic masterpiece in the heart of midtown Toronto.


Slate Asset Management is a leading Canadian private equity investment firm with over $6.3B of assets under management and over $1B under development across Canada, the United States, and Germany. Slate boasts a wide variety of capital sources as well as a portfolio encompassing multiple asset classes, including office properties, commercial buildings, and most recently, residential properties. Slate owns many commercial properties around Yonge and St Clair, and One Delisle will be its flagship residential property.


Jeanne Gang founded Studio Gang in 1997 in her home city of Chicago. She is globally renowned as a visionary architect who expands architecture’s traditional boundaries and elevates it to new heights, as seen in projects like Aqua Tower in Chicago, Tour Montparnasse in Paris, and the Royal College of Art Battersea Campus in London. Her work underscores the essential relationships between individuals, communities, and environments. Gang has been recognized with myriad architectural awards and is a MacArthur Fellow, a member of France’s Légion d’honneur, and an honorary fellow of the Royal Architectural Institute of Canada. She was named as one the 100 most influential people in 2019 by Time Magazine – the only architect on the list.

WZMH Architects is a Toronto-based architectural firm with 58 years of experience and over 150 awards. WZMH is known in the industry for the quality of the firm’s design, its technical competency, and professional reliability delivered across all levels of its leadership team and staff. They specialize in tall, landmark structures such as Bay Adelaide Centre, Royal Bank Plaza, and the CN Tower.



One Delisle will become an architectural landmark distinguished by its unique exterior. The building organically evolves from a pattern of rectangular modules at its square base to a honeycombed arrangement of hexagonal modules as it rises, and is ultimately capped by a 16-sided rounded peak. These modules, varying in depth and shape, will provide for a mix of balconies and unit types to accommodate residents of diverse needs.


Your home will be located in Deer Park, one of the most desirable neighbourhoods in Toronto. This affluent community is the perfect balance of residential buildings, commercial properties, and greenspace, making it an ideal place to live, work, and play. You’ll be within walking distance of the sprawling David A. Balfour Park, part of Toronto’s lush natural ravine system. In addition, Slate has enlisted the help of Janet Rosenberg + Studio to revitalize and expand the adjacent Delisle-St Clair Parkette by 50%, ensuring that residents have multiple ways to connect with nature.

One Delisle will be located close to several highly regarded educational institutions. Nearby schools include Deer Park Junior and Senior Public School, Brown Junior Public School, and St. Anselm Catholic School. Three of the best private schools in Canada, St Michael’s College School, Upper Canada College and The Bishop Strachan School, are less than an 8 minute drive from your home. Finally, the University of Toronto and Ryerson University are each less than 15 minutes away by subway.

Yonge St is overflowing with restaurants, cafés, and bars serving delicious, internationally inspired food and drink. Some within a 5 minute walk include Nove Trattoria, Barnsteiner’s, Union Social Eatery, and Sushi Gen. Also, you can keep your fridge and pantry well stocked with Loblaws and Sobeys both in walking distance. Ate too much? You can burn off those extra calories at Goodlife Fitness and Modo Yoga, both of which are just steps from your home.

Midtown Toronto is incredibly well connected to entertainment options, attractions, and activities that are fun for people of all ages. Explore new trails teeming with flora and fauna in the parklands and ravines right beside your home. Enjoy the picturesque gardens and exquisite summertime concerts at Casa Loma, or test your wits in their escape room. Or, bring your kids to Sky Zone Trampoline Park for an unforgettable day of flying through the air! And with the TTC right outside your door, downtown’s nightlife, events, and entertainment are always close at hand.
