Dominion Square Building
The Dominion Square Building, also known as Édifice Dominion Square, is a landmark office building and shopping area in Downtown Montreal. It sits at 1010 Sainte-Catherine Street West and faces Dorchester Square to the north. Dorchester Square Street connects Peel Street to Metcalfe Street and leads to a 600‑car underground parking garage under the building.
Built between 1928 and 1930 in the Beaux-Arts style, the building opened around 1929. It stands on the former Erskine Presbyterian Church site (c. 1866) and was designed by Ross and Macdonald. The structure has 12 floors above ground and a T-shaped shopping concourse. The main entrance opens to the office tower with escalators to a mezzanine overlooking the ground floor, which was planned as an interior shopping arcade with access from both inside and outside.
From the third floor up, the façade steps back in a double comb shape to let in plenty of sunlight onto Sainte-Catherine Street and to give offices on higher floors better views. The exterior uses Alabama Rockwood limestone with Italianate decorative details.
In 1989, a second and third floor extension was added on the south side, creating an arcade with a green-glass solarium on top.
Current tenants have included a women’s wear retailer on Metcalfe Street, CKMI-DT (Global Television Network) on the 7th floor with a virtual studio, and WeWork occupying three floors (the main area on the second floor). The Montreal Tourism office occupied the southeast corner of the ground floor until 2020, and the Montreal Gazette was a major tenant from 2003 to 2019.
The building was purchased in 2005 by David Azrieli’s Azrieli Holdings Inc. for about $78.25 million.
