Maison Alcan (English: Alcan House) is the world headquarters for Alcan, now part of Rio Tinto Alcan, and is located on Sherbrooke Street in the Golden Square Mile district of Montreal.[2] Completed in 1983, the complex's integration of new construction with restored or renovated buildings marked a turning point in corporate Montreal's approach to development.[3]

Maison Alcan combined restored Golden Square Mile properties—Atholstan House, the Beique, the former Berkeley Hotel, the Holland House, as well as the Salvation Army's Montreal Citadel on Drummond Street—with a new aluminum-clad structure, known as the Davis Building. The Berkeley Hotel serves as the main entrance to the complex and its atrium, on Sherbrooke Street.[1] According to the La Presse newspaper, Maison Alcan marked the first time a major corporation based in Montreal had sought to preserve historic properties as part of a new headquarters. Given the controversial demolition of the nearby Van Horne Mansion, Maison Alcan was a significant step in the battle to preserve the architectural heritage of the Golden Square Mile.[4]


Maison Alcan was designed by the Montreal-based architectural firm of Arcop (Architects in co-partnership), with Ray Affleck as lead architect.[5] Peter Rose collaborated with Peter Lanken on the interior planning and design.[6]


In May 2011, it was reported that Rio Tinto Alcan was looking to sell Maison Alcan and move to new headquarters, due to the cost of renovating the building for a smaller workforce—and with the historic status of four of the seven buildings possibly complicating renovations. The complex was listed by real estate brokers Cushman & Wakefield, with a $30 million minimum bid.[1]

In 2015, Alcan moved its HQ from the building and relocated to the Deloitte Tower, which is located between Windsor Station and the Bell Centre.[7]

Maison Alcan was classified as a heritage immovable by the Ministry of Culture and Communications the 23 February 2017.[8]
