About Stackpole
Ontario roots. Global reach.
From a manufacturing shop founded in 1906 to a global automotive supplier, Stackpole’s story is one of continuous engineering progress.
Our story
More than a century of precision.
Stackpole International began in 1906 and grew alongside Ontario’s industrial economy. Across generations of vehicle technology, the company developed deep capability in precision manufacturing, fluid systems and powder metal components.
Today, Stackpole serves global automotive programs as a tier-one supplier. Its work sits inside demanding powertrain and transmission applications where consistency, durability and efficient operation matter.
The company’s Ontario operations continue to connect corporate leadership, engineering, development and manufacturing across Ancaster, Stratford and Mississauga.
