Frank Martinitz, a young entrepreneurial tool and die maker from Germany, started Commercial Spring and Tool Company Limited (CST) in the early seventies.  The company started in a small industrial unit in northern Toronto manufacturing metal components for the telecommunication and automotive industries.  With rapid growth CST required larger facilities.  In the early eighties the company moved to a modern facility in Mississauga which it built on Matheson Blvd.  160Watline With increased growth in the early nineties a larger facility was required and one was purchased on Watline Ave in Mississauga. This facility housed the Stampings wire forming and spring winding operations. While the Matheson building was converted into a heat treat facility which allowed the company to be more vertically integrated. In the mid nineties a new coating operation was added to this location.  A further smaller facility was purchased in the early nineties on Watline ave to accommodate a state of the art tool room and a new compression and prototype spring manufacturing business.  In the Mid nineties an addition was added to the main facility to accommodate a shipping and receiving warehouse.  The company quickly grew out of these two locations and in the late nineties rented space on Kennedy blvd and Mc Adam Ave to accommodate this growth.  At this time the company ventured into motion cables used in the automotive industry.  In the November 2005 a large industrial building was purchased on Kennedy Blvd in Mississauga to consolidate the warehouse, spring winding and forming business under one roof.  Commercial continues to grow despite downturns in the economy.
