Koss Aerospace was established in 1975 in Mississauga, Ontario. Originally founded as Koss Machine & Tool Company. The company established it’s reputation by focusing on high quality production of aircraft components.  During the early years of business, the company built parts for McDonnell Douglas and Dehavilland Aircraft. Koss was recognized as a Gold Certified Supplier to McDonnell Douglas/Boeing and maintained a ship to stock status.

The company has since changed its name to Koss Aerospace to emphasize their presence in the Global Aerospace and Defense Industry. Today Koss Aerospace proudly continues to supply parts for those same customers; Dehavilland which is now Bombardier and The Boeing Company.
