In the year 1934, Mr. Harry McCoy, the founder of the McCoy organization formed the McCoy Machinery & Supply Co. Ltd., located at 258 Catharine Street North in the City of Hamilton, where, general machining and pattern making was done. Harry McCoy and his son Archie purchased Kerr & Coombes Foundry in downtown Hamilton in 1945. This being a continous operating foundry for over 100 years. In these early years grey iron was poured into molds of bank sands, drawn from nearby fields and re-worked with water each day, by hand shovel. The evolution of silica sands and binders replaced bank sand molding in the mid 1950’s. This process allowed McCoy Foundry to expand in production size and quality.

In 1970 Archie moved the foundry to its existing location in Troy. Today the foundry sits on 650 acres of farm and industrial land. A third generation of the McCoy Family is now operating the organization, with the addition of Archie’s sons Harry and Paul.
