Bohne Spring was established in Canada in 1891, known then as W. Bohne & Company Limited. The company was first formed to manufacture piano hammers for the Canadian Piano Producers, later adding on the production of piano bass strings and the jobbing of piano wires and parts. 

During the Second World War, the piano industry became a depressed industry, so the company appealed to the federal government for assistance in a new endeavour. It was at the suggestion of the Defence Production Department that the company enter the spring-producing field, as there was a need for increased production in Canada. The company began producing springs in 1943.

When the war ended, there was an even greater demand for springs, and the company needed to expand into a larger manufacturing facility. Property in Toronto was purchased in 1945, and Bohne moved into the 7,200-square-foot  facility in 1946.

In the next few years, a steady increase in volume of business necessitated the addition of a second story of equal size, which was completed and occupied in 1951.

During the late 1950s and early 1960s, the piano parts division of the business became less viable, so the company discontinued that part of its operation in early 1965. At the same time, the company changed its name to Bohne Spring Industries Limited.

Further expansion happened in 1969 when the company added another 14,000 square feet of manufacturing space, enabling it to add more equipment to increase efficiency and capacity.

Growth continued through the 1970s and into the 1980s until the plant was at full capacity and additional space was required. In 1985, the company moved to a larger facility — a 44,000-square-foot plant in Etobicoke, Ont. 

In 1988, Bohne Spring acquired Automated Spring Industries and kept this business as a separate entity until 1993 when it amalgamated the two operations into its Etobicoke facility.

In 2007, the company acquired Hamond Ind. Ltd., which specialized in Verti-Slide formed stamping, and amalgamated this business into its Etobicoke plant, too. 

In 2009, the company acquired the assets of OPUS heat treating, which specialized in the hardening and tempering of spring steels using the Austempering process. Two ovens are now located in Bohne’s plant.
