Cornwall’s paper industry started with the Toronto Paper Company. Later TPC was sold to Howard Smith Paper Mill. Generations of Cornwall families worked at the mill and lived in Smithville, the name given to the residential area surrounding the mill. Later, Domtar bought the mill and ran it successfully for many years. Smithville with its street names named after trees (Hickory, Elm), etc. was torn down for mill expansion although Pine Street on the East side of Brookdale remains. When world markets began to change the Domtar mill in Cornwall was closed in the new millennia. All of the buildings have been torn down, leaving only the tall smoke stacks and the main office structure. Domtar also owned the “No-Co-Rode” mill that made sewer pipe from waste paper and cardboard, cooked in tar/pitch under pressure. Many of the homes built in Cornwall in the 1950s and ’60s have No-Co-Rode sewer pipes leading to street mains, it was not a successful endeavor. The paper/tar piping tends to collapse underground pressure, blocking sewers. The excess or off-spec piping was dumped at the rear of the mill near Cumberland and Ninth Streets. The land is now being excavated and cleaned for development.
