Robertson Masson & Co. was an import-export company that existed under several names between 1811 and roughly 1900. Initially owned by brothers William and Hugh Robertson, and based in Glasgow, Scotland, the business expanded to Canada. The business dealt in import of goods to Canada, especially textiles, and export of Canadian goods to Europe, especially wheat and potash. In 1915, Joseph Masson became a senior partner and the company operated on Montreal under the name Robertson, Masson & Co. In 1930, they established a branch in Quebec City under the name Robertson, Masson, Strang & Co., overseen by John Strang, who was later succeeded by Charles Langevin. After the deaths of Strang and Masson in 1841 and 1847, new partners were brought in and the Montreal and Quebec companies became Masson, Bruyère, Thomas & Co. and Langevin, Masson, Thibaudeau et Compagnie, respectively. By 1859, a number of the partners retired or left the business, leaving the enterprise to Thomas and Thibaudeau. The company eventual became Thibaudeau Brothers & Co in the 1870s, and it contiued to exist under that name until at least 1895.
