The Ontario Paper Company Ltd.
In 1912, the Ontario Paper Company was incorporated as a subsidiary of the Chicago Tribune newspaper under the direction of publisher Robert McCormick. A paper mill was constructed south of here on the banks of the Welland Canal. On September 5, 1913, its No.1 Paper Machine began producing newsprint for the Tribune. Without sufficient timber in southern Ontario, pulp wood was shipped here by water from Lake Superior and Quebec's North Shore. The mill, designed and managed by engineer Warren Curtis Jr., was an innovative combined pulp and paper operation that used hydro-electricity from Niagara Falls. Some early mill employees formed Local 101, International Brotherhood of Paper Makers, the first papermakers' union in Canada. In 1980, the company built a new mill at Thorold and the company was sold in 1996. The Ontario Paper Company Ltd. was committed to its employees and community, and was a technological leader. It pioneered modern operational practices, including the production of valuable chemical byproducts.
