Habitat 67, or simply Habitat, is a model community and housing complex in Montreal, Quebec, Canada, designed by Israeli/Canadian architect Moshe Safdie. It was originally conceived as his master's thesis in architecture at McGill University and then built as a pavilion for Expo 67, the World's Fair held from April to October 1967. It is located at 2600 Avenue Pierre-Dupuy on the Marc-Drouin Quay next to the Saint Lawrence River. Habitat 67 is widely considered an architectural landmark and one of the most recognizable and spectacular buildings in both Montreal and Canada. In 2017, Canada Post issued a commemorative stamp for the 50th anniversary of Expo 67 featuring the structure.
