Montreal's first multidisciplinary design firm
GSM can be traced back to Jacques Guillon Designers, Inc., the first multidisciplinary design office in Canada, founded by architect Jacques Guillon in 1958. The firm participated in numerous landmark projects in various fields, including the signage and metro cars for Montreal’s metro system and several thematic pavilions at Expo 67 in Montreal. These projects attracted to the team the talents of Morley Smith, industrial designer in charge of the design of Montreal Metro cars, and the Swiss graphic designer, Laurent Marquart. Together, they added exhibition design to the repertoire of this versatile company. The team was completed by a fourth associate, Roger Labastrou, a Swiss architect in charge of the interior design department.
