About the test
By law, certain cars, vans, trucks, motorhomes and buses must pass a Drive Clean test before they can be licensed to be driven on Ontario roads.
The Drive Clean test determines if your vehicle meets Ontario emissions standards.
When to get the test
Generally, you need to get the test every 2 years, once your vehicle is 7 years old. Larger vehicles (called ‘heavy-duty’ vehicles) require the test every year, once they are 7 years old.
The Ministry of Transportation will notify you when your vehicle needs an emissions test, when you receive your registration renewal documents (either online or in the mail).
Find out if you need a test
Depending on the vehicle, the test could involve:
- an on-board diagnostic (OBD) test (reads emissions information from the vehicle’s computer)
- a tailpipe test (measures tailpipe emissions)
- an opacity test (measures smoke density in diesel-fuelled vehicles)
Test facilities (who can test)
Tests must be performed at an accredited facility by a certified inspector. These private operators run the test and provide you with a test report.

Your vehicle may receive:
- a pass
- a conditional pass or
- a fail
- a not ready result
You need to receive a ‘pass’ or ‘conditional’ pass to renew your licence plate sticker.
Types of vehicles
Two types of vehicles are subject to the test. The process and rules are different for each type.
- light trucks and motorhomes — with a gross vehicle weight rating (or gross combined weight rating) of 4,500 kg or less
- large trucks and motorhomes — with a gross vehicle weight rating (or gross combined weight rating) of over 4,500kg
You do not need an emissions test for:
- most-hybrid electric vehicles
- light-duty vehicles with a model year before 1988
- vehicles that are plated “Historic” under the Highway Traffic Act
- light-duty commercial farm plated vehicles
- kit cars
The cost of a Drive Clean test depends on:
- the type of vehicle (light-duty or heavy-duty)
- the type of test (first-time test or a re-test)
Up to $30 (plus tax)
Each facility sets its own fees. Applicable taxes are extra.
Re-test fees (light-duty vehicles)
Up to $17.50 per test, if it is done at the same facility that performed the initial test.
$30 (plus tax) if the re-test is performed:
If your vehicle fails and requires repairs, you may also have to pay a separate fee to have a diagnostic performed.
This diagnostic may be needed, if a Repair Technician has to examine your vehicle to determine why it did not meet emissions standards. Facilities set these fees.
If your vehicle is due for a Drive Clean test, you will see an asterisk (*) on the notice form you get from the Ministry of Transportation when it’s time to renew your vehicle’s registration.
