ABOUT GUSPRO INC.
Guspro Inc. was established in 1932 as the Canadian division of Sunnen Products Company, headquarted in St. Louis, MO. For over 50 years, Guspro distributed and manufactured Sunnen honing products, including machines, abrasives, and tooling. In 1980, Canadian manufacturing for Sunnen Products was set to wind down, and so Guspro Inc. began a transformation. Today the company is comprised of four unique but complementary divisions.

Our Facility

Located in Chatham, Ontario, Guspro Inc. is strategically positioned to serve both the Canadian and U.S. markets. Easy to get to, our headquarters is only 5 minutes from Highway 401, and less than an hour from Detroit, Michigan. While the company has been located in Chatham since 1932, Guspro relocated its head office and manufacturing operations in 2012. Although the new building was only 5km down the road, planning for the move took over a year.
Our new home is a modern, 100,000 square foot facility with plenty of room for additional expansion. In addition to upgraded manufacturing equipment, including a new 52' paint booth and a 80' x 200' bay with a 15 ton craneway, we're pleased to acommodate two product showrooms, a new R&D lab, and the world's only skate-sharpening museum.
