Built in Ottawa.
Built to Last.
Locally owned. Decades of experience. Honest diesel repair that Ottawa’s commercial operators have relied on since 2003.
A Shop You Can Count On
Scott Diesel Ltd. was founded with a simple goal: provide the kind of honest, skilled diesel repair that Ottawa’s fleet operators couldn’t find anywhere else. No upsells, no runarounds — just straight talk and quality work.
Over the years we’ve grown from a small operation into a full-service heavy diesel facility trusted by municipal fleets, construction companies, owner-operators, and everything in between. Our shop in Carp is equipped with modern diagnostic tools, a dedicated mobile service fleet, and experienced technicians who’ve seen it all.
We serve clients who need fast turnaround, accurate estimates, and techs who understand that every hour of downtime costs money. That’s the culture we’ve built — and it’s why our clients keep coming back.
