1000 Sherbrooke West

1000 Sherbrooke West is a skyscraper in downtown Montreal with 28 floors and a height of 128 meters. The tower features raw concrete elements on its exterior and combines concrete with glass surfaces.

The building was completed in 1974 and initially served as headquarters for the International Civil Aviation Organization. This role established Montreal as a center of global aviation governance.

The building exemplifies the Brutalism movement of the 1970s through its raw concrete surfaces and strong geometric forms. These distinctive features shape Montreal's downtown landscape.

Access is available through multiple entrances on Sherbrooke Street with clear sightlines and easy orientation. Proximity to public transit makes the location easily accessible for visitors.

In 1987, the Montreal Protocol, a major international treaty protecting Earth's ozone layer, was signed in this building's ICAO offices. This agreement remains one of the most successful environmental treaties globally.
