Montreal-based architecture firm Provencher_Roy has acquired Ottawa’s GRC Architects in a move that will create one of the capital’s largest companies in its field.
The firms announced the transaction on Tuesday. Terms were not disclosed.
Founded in 1985, GRC Architects was Ottawa’s seventh-largest architecture firm before the merger with a staff of eight registered architects, according to OBJ’s 2024 Book of Lists. Its past projects include the Canadian War Museum (a joint venture with Moriyama Teshima Architects) and the embassies of Kuwait and the United Arab Emirates.
