Square One Shopping Centre Expansion

At just over 1.2 million ft2 (111.485 m2), prior to commencing this renovation/expansion, Square One was already one of Canada’s largest and busiest shopping centres.

In considering contemporary retail design, this addition of more than 320,000 ft2 (29,730 m2) of retail space, along with a new Cineplex Odeon movie theatre, street presence with a clear arrival point was critical for the success of both mall and theatre. With that in mind, the new entrance was articulated as a girdle-shaped glass rotunda set within a beautifully landscaped street adjacent to Duke of York Boulevard. With ample surface parking nearby and the car drop off positioned next to its lower level entrance, this new round glass architecture has become a beacon both day and night. Further, the rotunda’s soft shape partners well with the neighbouring round forms of the Living Arts Centre, Palladium and the City Hall’s council chambers across the street.

Internally the public routes throughout this addition have also benefitted from the new architecture, with bowed, sky-lit ceilings that flood the interior’s volume with natural light, resulting in a pleasant shopping experience.
