Scott Diesel Ltd. was founded with a simple mission: provide honest, reliable diesel repair services to the Ottawa community. What started as a small shop has grown into a trusted name in heavy diesel repair, serving commercial fleets, municipalities, and owner-operators throughout the region.
Located in Carp, Ontario, our shop is strategically positioned to serve the entire Ottawa area. We’re not a dealership — we’re a working diesel shop that understands the importance of keeping your equipment running. Our reputation has been built one repair at a time, through honest work and fair pricing.
Over the years, we’ve invested in the latest diagnostic equipment and ongoing training for our technicians. But we’ve never lost sight of what matters most: treating our customers’ equipment with the same care we’d give our own.

“To keep Ottawa’s heavy diesel equipment running at peak performance through honest, reliable service — delivered by certified technicians who take pride in their work.
