Nobody enjoys paying for an inspection only to be handed a list of failures. The good news is that a large share of Ontario safety inspection failures are not hidden mechanical problems — they are burnt-out bulbs, worn tires, and cracked windshields that you can identify yourself in about twenty minutes.
This checklist follows the same order a licensed technician works through the Ministry of Transportation's Passenger/Light-Duty Vehicle Inspection Standard. It will not catch everything — some items genuinely require a hoist and measuring tools — but it will catch the cheap, obvious failures before they cost you a re-inspection.
1. Walk around with every light on
Get a helper, or park facing a window at night. Turn on the headlights and check both low and high beam. Have your helper press the brake pedal, then work through the turn signals, hazards, and reverse. Then check the licence plate light and the daytime running lights.
Why it matters: every required lamp must illuminate fully and correctly. A single burnt-out bulb fails the inspection. This is the most common and most avoidable failure there is, and a bulb is usually a few dollars.
Also check the indicator lamps on your dashboard: the high beam indicator, the turn signal indicators and the hazard indicator all have to work.
2. Look closely at your headlight lenses
Badly hazed, yellowed or clouded headlight lenses are not just cosmetic. The standard fails headlamps whose lenses are crazed, clouded, fogged or damaged enough to materially impair the beam pattern or scatter excessive light toward oncoming drivers.
If you cannot clearly see the reflector inside the housing, the lens is a problem.
3. Check tire tread at the worst spot
Ontario's limit is 2 mm of tread depth, measured at the shallowest point in a major groove — not an average across the tire. Tires wear unevenly, so check the inner and outer shoulders as well as the centre.
A quarter works in a pinch: insert it into the groove with the caribou's nose pointing down. If the tread does not reach the nose, you are close to the limit and worth measuring properly.
4. Inspect tire sidewalls
Look for bulges, cuts and cracking on both the outer and inner sidewall. The standard fails a sidewall bulge more than 10 mm high, exposed body cords, ply separation, and any plug repair in the sidewall. A bulge means the internal structure has already failed — that one is worth fixing immediately regardless of any inspection.
5. Confirm your tires match
The left and right tires on the same axle must be the same nominal size. And radial tires cannot be mixed with non-radial tires anywhere on the vehicle. If you have replaced one tire at a time over the years, this is worth verifying against the sidewall markings.
6. Measure your windshield damage
This one has a specific rule that surprises people. Inside the area swept by your wipers, a crack longer than 50 mm fails, and a stone chip larger than 13 mm across fails. Outside the swept area, the same damage passes.
A crack that runs through both layers of glass fails anywhere on the windshield.
So a chip low on the passenger side may be perfectly fine, while an identical chip in front of the driver is not. Measure before you assume.
7. Test the wipers, washers and defroster
Run the wipers through every speed. They must operate correctly in all positions and must park properly when switched off. Torn or ineffective blades fail. Then test the washer — it must actually deliver fluid to the right part of the windshield. Finally, run the heater on High and confirm strong airflow to the windshield and front side windows.
8. Press the horn
Every vehicle needs at least one operating horn, clearly audible. It takes two seconds to check and it does fail vehicles.
9. Note which dashboard warning lights stay on
Turn the ignition on and watch the bulb-check cycle, then start the engine.
- Airbag (SRS) light staying on: fails.
- Brake system warning light indicating a fault: fails.
- Stability control (ESC) fault on a vehicle built on or after September 1, 2011: fails.
- ABS light on a normal passenger vehicle: does not fail, but it is recorded on your report.
- Tire pressure (TPMS) light: does not fail, but it is recorded.
- Check engine light: not itself a safety failure, but worth diagnosing.

10. Test every seat belt
Pull each belt all the way out and let it retract. Buckle and unbuckle each one. Look at the webbing for fraying, cuts or tears. Belts fail for damaged webbing, broken anchors, retractors that will not extend or retract properly, and buckles that do not lock or release cleanly.
11. Listen to your exhaust from cold
Start the car cold and listen at the back and underneath. A ticking or roaring that changes with engine speed usually means an exhaust leak. Cracked, perforated or leaking exhaust components fail, as does any exhaust that lets gases into the cabin.
Note that the standard explicitly treats minor leaking and soot tracks at exhaust joints as normal, so light staining alone is not a failure.
12. Look underneath for rust and drips
This is the one that catches older Ottawa vehicles. Look at the rocker panels — the body section below the doors — and at the floor pans and frame rails. Press firmly. If metal flexes, crunches or perforates, you have a structural problem.
Surface rust is normal and explicitly not a failure. Perforation of a structural area is. Our guide on why Ottawa cars fail on rust explains exactly where the line falls.
While you are down there, look for fresh drips on the ground. Brake components fail at the mildest leak category — a damp film is enough.
What this checklist cannot tell you
Three of the most common failure areas genuinely need a shop:
- Brake wear. The standard requires wheels to come off, with rotor thickness and the friction material thickness of both pads measured and recorded. You cannot judge that through a wheel spoke.
- Suspension and steering wear. Ball joint and tie rod wear is measured against manufacturer limits with the vehicle raised and the components unloaded.
- Structural corrosion. Rust often looks worst where you can see it and is worst where you cannot.
Before you book
If your pre-check turned up a burnt bulb, a worn wiper blade or a low tire, fix those first — they are cheap, and clearing them means the inspection focuses on things that actually need a technician.
If you found something bigger, tell us when you book. We would rather look at it up front and give you a straight quote than have you pay for an inspection that was always going to fail.
Frequently asked questions
How much does an Ontario safety inspection cost in Ottawa? Ontario does not set a fixed price; each licensed Vehicle Inspection Centre sets its own. At Franco Garage a Safety Standards Certificate inspection starts at $174.95, with the exact figure depending on your vehicle. That covers the full inspection against the provincial standard — wheels off, brakes measured, road test — and the certificate itself if the vehicle passes.
If my car fails, do I have to do the repairs at the same shop? No. The inspection report is yours, and you can take the repairs anywhere. If we do the work, we re-inspect the failed items and issue the certificate once the vehicle meets the standard, so you are not paying for a second full inspection elsewhere.
How long is a safety certificate good for? 36 calendar days from the inspection date. There is no extension, so line up your ServiceOntario visit before you book.
Can I fail for something that is not actually unsafe? The standard is a written list of pass/fail criteria, not a judgement call, and some items surprise people — a missing driver's side sun visor, a non-functioning odometer, a wiper that does not park correctly. That is also its strength: a licensed technician cannot invent a failure, because every result has to match a specific criterion and, under DriveON, is submitted digitally to the province.
