Emissions Test-min

What Drive Clean Is

Drive Clean is Ontario's mandatory vehicle emissions inspection and maintenance program. It improves our health and environment by reducing smog-causing pollutants through testing and repairing vehicle emissions systems.

Owner’s Responsibilities

Under Drive Clean, your vehicle must have an emissions test to renew your registration and license plates. If your vehicle requires a test, this will be indicated by a red asterisk on the registration renewal document sent by the Ministry of Transportation three months prior to expiration. It is important to have your Drive Clean test conducted several weeks prior to renewal as more than one attempt or vehicle repairs may be required to pass.

As a consumer-protection measure, an emissions test is also required when buying or selling used vehicles with a model year older than the current calendar year. This helps ensure that consumers do not purchase a used vehicle with emissions problems.
