What Is an Emissions Test?
An emissions test is a procedure done to gauge whether a vehicle adheres to the emission standards set by the province of Ontario.
Emissions tests typically check the levels of the following chemical compounds in your vehicle’s exhaust:
- Carbon monoxide (CO)
- Carbon dioxide (CO2)
- Hydrocarbons (HC)
- Oxygen (O2)
- Nitrogen oxides (NOx)
Why Do I Need an Emissions Test in Ontario?
Emissions tests are conducted to regulate the amount of pollutants released into the air. The goal is to reduce air pollution and, ultimately, keep Ontarians and their environment safer and healthier.
Emissions testing in Ontario began in 1999 when the government unveiled its Drive Clean initiative. Under this program, all vehicles that were seven years and older were required to undergo emissions testing. Failing the test meant that drivers were not allowed to renew their vehicle registration and license plates.
20 years later, the Ontario government retired the Drive Clean movement in 2019 following criticisms of inefficiency and unnecessary expenses to taxpayers. Over those two decades, technological advancements have allowed car manufacturers to create better, cleaner engines – negating the necessity of the program for light vehicles.
Today, the Ontario government conducts emissions testing and safety inspections through the DriveON program, which is designed specifically for commercial motor vehicles using heavy diesel. According to the Ontario government website, the program is meant to:
- Allow owners of commercial vehicles to save time and money
- Reduce instances of fraud
- Bring down levels of environmental pollutants
- Maintain the safety of our roads
Light-duty vehicles such as cars, SUVs, and small trucks are not required to undergo emissions testing under this program.
When Do I Need an Emission Test in Ontario?
As mentioned above, you will need to undergo an emissions test in Ontario if you drive a heavy-duty diesel-run commercial vehicle that weighs 4,500 kilograms or more and if that vehicle is seven years old or older.
Many heavy-duty diesel commercial vehicles must undergo emissions testing annually when renewing registration. Additionally, those registering as new owners of the aforementioned types of vehicles are also required to undergo testing.
The Ontario government will send you a renewal notice in the mail once per year. You may also be stopped and subjected to an inspection by an enforcement officer anywhere in the province if:
- Your vehicle is believed to be producing excessive exhaust; and/or,
- They find that your emission control equipment was removed or tampered with
Vehicles that don’t comply with Ontario’s emissions standards will be subject to compliance or enforcement action. This could mean facing verbal warnings or fines.
How Much Is an Emission Test in Ontario?
It costs around $130–$140 plus tax to complete an emissions test for heavy-duty diesel commercial vehicles (over 4,500 kg) that require emissions testing.
What to Expect at an Ontario Emissions Test Check
Ontario emissions tests for heavy-duty diesel-run commercial vehicles typically take between 15 and 30 minutes and involve the following procedures:
The Best Way to Pass an Emissions Test in Ontario

Key Advice from MyChoice
- Keep your vehicle properly maintained. Issues like engine problems, old oil, or faulty sensors can cause higher emissions and failed inspections.
- Fix warning lights before testing. A check engine light can automatically cause problems during inspection.
- Address issues early if you drive a commercial vehicle. Failing emissions testing can delay registration and interrupt business operations.
