The mill was built in 1946 and struggled over the years. Between 1946 and 2004, it was successively purchased by Air-Cell Insulation, Barrett Co., Allied Chemicals Canada and Canadian Gypsum and eventually bought by Cascades (Les Matériaux Cascades inc.) in 1980. Louiseville Specialty Products Inc. acquired the mill in 2004.
