Founded in 1965 by Robert (Bob) Ireland

Founded in 1965 by Robert (Bob) Ireland, Guelph Manufacturing opened for business as Guelph Tool Company, a machine job shop servicing local industry with machining work, building tools, dies, jigs and fixtures. Guelph Tool grew steadily over the years, the result of exceptional quality that customers were eager to share. As the business grew, Bob welcomed the opportunity to expand into manufacturing.


In 1978 the company’s first automotive contract was awarded from General Motors. From that initial opportunity through the 1980’s the company grew its automotive OEM customers, while maintaining and growing an automotive Tier One customer base.

Guelph Tool began adding products and developed a niche for forming wire, rod and steel tubing, which includes products like our seat frames and headrest inserts. The company also added manufacturing capabilities such as assembly and welding.

Through the 1990’s and early 2000’s the company continued to grow, adding capabilities such as automation, robotics and CNC. Shortly after, in 2006, the company opened a 90,000 sq. foot heavy stamping facility in Guelph.

Now, as Guelph Manufacturing Group, the company continues to expand its capabilities while maintaining the same commitment to quality that Bob Ireland had when founding the company more than 50 years ago.


Guelph Manufacturing is committed to delivering on our customers’ business needs by providing superior product quality and industry-leading services.
