Take a look inside OPW

Original Parts Warehouse

Founded in 1999, The Original Parts Warehouse (OPW) has developed a reputation for combining quality products with dependable service. What started off as a small parts operation in Hamilton, would eventually evolve into something much greater!

Our tenacity and dedication to build strong lasting relationships with our suppliers has enabled us to grow into the distribution icon we are today. That small OPW operation in Hamilton naturally ‘outgrew’ itself, and began a gradual expansion across Ontario and later—Canada.

We have worked hard to establish and represent a standard of premium quality. With national reach, we are able to service the industry with any heavy duty truck parts you need! OPW is committed to its ever-growing hard parts offering for all applications, including: Truck & Trailer, Industrial, Waste Management, Transportation, Couriers, Forestry, Construction, Mining, Oil, Cement, Quarry, Agriculture, and more!
