Why truck owners come here
Red Seal certified technicians. The Red Seal is the national standard for skilled trades in Canada. It takes years of training, logged work hours and a national exam.
Diesel is the job
Powerstroke, Cummins and Duramax every day, and other diesel makes and models too. We know where each platform tends to fail.
We test before we replace
A scan tool shows where to look. We then test the circuit or part to find the cause, so you don't pay for parts you didn't need.
Plain answers
We tell you what's wrong, what your options are and what it will take, without the jargon. You decide what gets done.
Built for working trucks
Maintenance schedules, inspections and service records for company trucks, so problems get caught early and trucks get back to work.
About the shop

That means quality parts, technicians who know diesel engines, and clear explanations of what’s going on with your truck so you can make an informed decision.
