Ignition Interlock Program

About the program

The Ignition Interlock Program is a mandatory program for drivers who have been either:

• convicted of an impaired driving offence under the Criminal Code of Canada
• suspended three or more times within a 10-year period for impaired driving offences (called “administrative suspensions”)

To continue driving after your licence is reinstated, you must have an ignition interlock device installed inside your vehicle. The device is an in-car alcohol breath screening device with the ability to prevent the vehicle from being driven if it detects alcohol in your system.

The length of time you must have the device installed depends on the Ignition Interlock condition (“I”) placed on your driver’s licence:

The Ignition Interlock condition may get extended if you register a performance failure or violate the terms of the program.

Performance failures include:

• blowing over blood alcohol concentration (BAC) of 0.02
• missing a rolling re-test (the device will prompt drivers to pull over and provide a breath sample while the vehicle is running to verify the driver has not consumed any alcohol after initially starting the vehicle)

Extensions for performance failures:

• first time convicted offenders are monitored for performance failures in the last 3 months of their ignition interlock condition and will receive a 3-month extension
• for subsequent convictions, offenders are monitored in the last 6 months of their ignition interlock condition and will receive a 6-month extension

Program violations include:

• tampering with the device as reported by the ignition interlock service provider
• convictions for tampering with the ignition interlock device
• convictions for driving without the approved ignition interlock device
• missed appointment with the ignition interlock provider

Drivers are monitored for program violations throughout the entire duration of their ignition interlock condition. Extensions for violations include:

• first time convicted offenders receive a 6-month extension
• second time convicted offenders receive an 18-month extension
• for subsequent convictions, offenders receive a 3-year extension

If you have an offence date prior to July 1, 2026, and you choose not to install an interlock device, you cannot drive until the condition is removed from your licence.

If you are convicted of an impaired driving offence that occurred on or after July 1, 2026, you must install an ignition interlock device. If you install the ignition interlock device within 30 days of licence reinstatement and adhere to the terms of the program, you may be eligible for the following ignition interlock condition periods:

• first-time offenders: minimum of 9 months
• second-time offenders: minimum of 2 years

Requirements:

• You must install the device within 30 days of licence reinstatement and keep it installed for the entire required period. If you do not install it within 30 days, or if you remove it early, you will no longer be eligible for the ignition interlock condition periods listed above and will have to complete the standard 1-year or 3-year ignition interlock condition instead.
• Your driver’s licence must remain valid and in good standing. If your licence is suspended or cancelled at any point, you will be required to complete the standard 1-year or 3-year ignition interlock condition period.
• You must adhere to the terms of the program. If you do not comply, you will no longer be eligible for the ignition interlock condition periods listed above and will face further extensions of your ignition interlock condition.
• If you register a performance failure or program violation, your ignition interlock condition period will be extended.
• Time already spent with the ignition interlock device installed will still count toward your required installation period, even if there is a performance failure, program violation, licence suspension or cancellation, or removal of the device.

If you fail to install an ignition interlock device for the required installation period, the condition will remain on your licence. You cannot drive a vehicle without an approved ignition interlock device until the condition has been removed from your licence.

Reduced Suspension with Ignition Interlock Conduct Review Program

For first-time or second-time offenders convicted of alcohol impaired driving under the Criminal Code, you may be able to reduce your licence suspension by meeting certain requirements. Learn more about this program.

How ignition interlock devices work

After the ignition interlock device is installed in your vehicle, you will need to blow into the device, located near the driver’s seat, before your vehicle will start.

If the device detects a blood alcohol concentration (BAC) over the preset limit of 0.02 the vehicle won’t start. If you are under the preset limit, the vehicle will start and you will be asked to provide breath samples at random times while the vehicle is running.

If you don’t provide a sample or if your BAC exceeds the limit, the device will:

• issue a warning
• record the event
• activate specific alarm systems (for example, lights flashing, horn honking) until you turn off the ignition

Installation and costs

You will need to register with one of the government-approved interlock service providers to have the ignition interlock device installed. For more information, please visit:

• Smart Start Canada
• ALCOLOCK Canada

Drivers are responsible for all installation and maintenance costs for the device. The device must also be inspected regularly by the service provider. The service provider will provide related information, including fees, when you register for the program.

Removing Ignition Interlock conditions

From a Criminal Code conviction

If you have completed the minimum period for your Ignition Interlock condition without any program violations, you can apply to have the condition removed from your driver’s licence.

Follow these steps to apply:

1. You will be mailed a Substance Use Assessment form 6 months before your condition removal date from the Ministry of Transportation.
2. Take the form to your physician, specialist, or nurse practitioner and have it completed in full with all questions answered.

3. Submit the completed form by mail or fax to:

   Ministry of Transportation
   Driver Medical Review
   77 Wellesley Street West, Box 589
   Toronto, Ontario
   M7A 1N3

   Fax: 1-800-304-7889 or 416-235-3400

4. You must also complete a final appointment with your ignition interlock service provider.

If you don't apply to remove the condition from your licence, it will stay on your licence. This means you will only be able to drive vehicles that are equipped with an approved ignition interlock device or be subject to penalties under the Highway Traffic Act.

If you are convicted of an impaired driving offence on or after July 1 2026, once the ignition interlock condition (“I”) is removed from your driver’s licence you will be subject to a minimum 6 month “P” licence condition, meaning you must have no alcohol and no drugs in your system when you drive.

From administrative suspensions

No application is required. The ignition interlock condition will automatically be removed if you have completed the minimum 6-month period without any program violations.

Penalties

If you are convicted of driving without an ignition interlock device or for tampering with it, you will face fines ranging from:

• $200-$20,000 for commercial vehicles
• $200-$1,000 for other motor vehicles

Vehicle impoundment

If you violate your ignition interlock condition, your vehicle can be impounded.

• If you are in the program because of Criminal Code conviction:
  • 45 days for a first offence
  • 90 days for a second offence
  • 180 days for a third or subsequent offence
• If you are in the program because of administrative suspensions:
  • 7 days

Additional charges

You can receive further charges under the Criminal Code of Canada or the Highway Traffic Act for program violations.

Vehicle owners who knowingly allow a person with an ignition interlock condition to drive their vehicle can also be charged.
