    Ontario MTO Safety inspection with a detailed written checklist. Pass or fail, you leave knowing exactly what your vehicle needs to stay roadworthy.

Our shop

A family shop, not a dealership conveyor belt

Ironclad Auto Service opened on Stone Road in 2009 with one bay and a simple rule: write the estimate before you touch the car. Fifteen years later, we run two full-service bays with four ASE-certified technicians and the same rule still holds. Our clients bring us their second vehicles too, and refer their neighbours, because they know the quote they see is the bill they pay. We stock parts for the vehicles we see most in Guelph and keep the wait to a minimum without cutting corners.

Customer results

What our customers say

Brought in my truck for a grinding noise. They had it diagnosed and back on the road the same afternoon, showed me the worn rotor before replacing it, and did not push a single thing I did not need.

I have taken both family cars here for four years. The quotes match the bills, the work is done right, and they call before adding anything. I have sent three people from my street here.

Engine light came on the morning of a long drive. They fit me in that day, ran the scan, and fixed a vacuum leak in under two hours. Fair price for the peace of mind.

Good to know

Common questions

Do I need an appointment for an oil change?
Walk-ins are welcome for oil changes and tire rotations, but booking ahead guarantees your time slot. You can book online or call us the morning of.
What does your warranty cover?
Every repair is backed for 12 months or 20,000 km, whichever comes first. If anything we fixed lets you down within that period, bring the vehicle back and we will make it right at no charge.
Can I drop off my vehicle and pick it up later?
Absolutely. We offer a free shuttle within Guelph for all-day repairs, and a loaner vehicle when one is available. Just let us know when you book.
Do you service all makes and models?
We work on most domestic and import vehicles, including Asian and European makes. Call ahead if you have an unusual or high-performance vehicle and we will confirm we can take it.
How do I know you will not add work I did not ask for?
We will not. Our policy is to write a full estimate before any repair begins and call you for approval on anything that comes up during the job. Nothing goes on your bill without your go-ahead.
