Inspections

What is an MTO annual safety inspection?+

A yearly inspection that commercial trucks and trailers in Ontario must pass. A licensed inspection station checks the vehicle against the MTO standard and applies a sticker if it passes.

How long does an annual inspection take?+

About 3.5 hours for a tractor and about 2 hours for a trailer, if it passes clean.

What happens if my truck fails?+

You get a written defect list and a quote. Most units are repaired and stickered in the same visit.

Do trailers need their own inspection?+

Yes. Each trailer needs its own annual inspection and sticker. See trailer inspections.

DPF, engine & diagnostics

Why does my truck keep going into derate?+

Usually an aftertreatment fault: DEF quality, a NOx sensor, a blocked DPF or a failed regen. We read the codes and find the cause. See DPF & aftertreatment.

How often should a DPF be cleaned?+

It depends on the engine and duty cycle. Trucks that idle a lot or run short trips need cleaning sooner than highway trucks. Your engine maker's maintenance schedule gives the interval, and we can check ash load when the truck is in.

Which engines do you work on?+

Cummins, Detroit, PACCAR, Volvo, Navistar, Hino and Mack. See engine repair.

How is diagnostic time billed?+

By the hour. The starting rate is on our pricing page, and we call before going past the time you approved.

Fleets & pricing

Do you have fleet accounts?+

Yes. Fleet programs cover PM schedules, staggered annual inspections and records ready for CVOR.

Do you quote before starting work?+

Always. Nothing is repaired until you approve the written quote.

Where can I see prices?+

Starting rates are on the pricing page. The final price depends on the unit and what we find.

Can you plan our PM schedule?+

Yes. Use the PM planner to build one, then send it to us.

Mobile & roadside

Do you do roadside repairs?+

Yes, across Mississauga and the GTA. See mobile & roadside repair.

What can't be fixed at the roadside?+

Anything that needs a hoist or a long teardown, plus annual inspections. Those are done in the shop.

Still have a question?

Ask a technician.

Call the shop and you'll talk to someone who works on trucks, not a call centre.
