Our History

A Second Generation Family-Run Business

Soo Foundry and Machine has been a fixture in the Sault Ste. Marie economy for more than 50 years. With a  solid reputation for  quality work, dependable service and innovative approaches to unique problems. Soo Foundry employs a workforce of 40-45 machinists, welders, millwrights, and hydraulic technicians.
The origins of  Soo Foundry are found in Northern Ontario at the turn of the last century when Sault Ste Marie was the hub for the forestry, mining and transportation industries.
Strategically located at the mouth of the St Mary’s River where Superior meets Huron and Michigan all of the local resource industries depended upon the transportation corridor provided by shipping on the Great Lakes.
Soo Foundry, initially called Northern Foundry was located on the Sault Ste Marie waterfront where repairing cargo ships was a huge part of their beginning business.
Wilfred and Jack Cohen started in the scrap metal business and bought the company in 1958. Business at that point included the manufacture of manhole covers for the city as well as a variety of other products.
When the city’s waterfront was redeveloped and the coal and repair docks disappeared to become the station mall, the civic centre and the Roberta Bondar Pavillion, the company made the trek to the new industrial area at the north end of the city on Drive-In Road.
The main building was erected in 1982 and has steadily expanded to the current 40,000 square foot facility they have today.
The current machine shop is filled with CNC machines, a welding shop and a hydraulic repair facility.
The foundry business was discontinued in 1982 but the company retained its name while focusing on machine, welding and hydraulic work.
Diversification was the key to their longevity with the addition of a steel warehousing service and hydraulics with the acquisition of Northern Fluid Power and Traders Steel Warehouse.
Through the 1990’s , hydroelectric work was an expanding part of the business and it continues to be strong today with contracts with contracts from Hydro clients located from Newfoundland to British Columbia.
