Constructed in the 1930s, the Montreal Chest Institute (MCI) was a key medical centre in the history of Montreal and Quebec. Neglected and finally abandoned, the campus will now be revived as a new life sciences hub specializing in research into respiratory illnesses, continuing the site’s original vocation. A new nine-storey addition will bring together researchers and health technology companies. A glazed atrium and rooftop garden will expand and frame views to the mountain, create a common meeting point and provide teaching spaces for the growing life sciences community.
