The Deloitte Tower (French: Tour Deloitte) is a 26-storey office building under construction in Montreal, Quebec, Canada, located between Windsor Station and the Bell Centre. Scheduled to be completed in summer 2015, the building will feature 495,000 square feet (46,000 m2) of office space, and 20,000 square feet (1,900 m2) of retail space. It is named for professional services firm Deloitte, which will occupy 160,000 square feet (15,000 m2) of office space in the building. It will also house the relocated headquarters of Rio Tinto Alcan, which will occupy approximately 190,000 square feet (18,000 m2) on the top eight floors of the building, after its move from Maison Alcan. The Deloitte Tower is planned as part of a larger, multiphase, mixed use project that will include retail and residential spaces. The building is owned by Cadillac Fairview.
