Dominion Square Building

Dominion Square Building is an office building with twelve floors and two facades in downtown Montreal. One side faces Sainte-Catherine Street, while the other overlooks Dorchester Square.

The building was constructed between 1928 and 1929 by the architectural firm Ross & Macdonald. It replaced the earlier Erskine Presbyterian Church that had stood on the site since 1866.

The building forms part of the Dorchester Square and Place-du-Canada heritage site, which shows how Montreal's architecture changed over the 20th century. Today, visitors can see how this space fits into the broader story of downtown development.

The building is located near Peel subway station and is easy to reach by public transit. Inside, there are various office spaces and a shopping gallery area that is accessible to pedestrians passing through.

The building contains the first wooden escalators in Montreal, leading down to a two-level shopping gallery with a distinctive double-comb architectural design. This gallery structure is a rare example of retail innovation from the 1920s era.
