Ontario’s Ignition Interlock program allows first-time impaired driving offenders to drive sooner. Under Stream A, if you plead guilty within 90 days, your 1-year suspension is reduced to a 3-month absolute suspension, followed by 9 months of driving with a breathalyzer installed in your car.
Losing your driver’s licence to a criminal impaired driving conviction in Ottawa can completely derail your life 🚗. While public transit like OC Transpo and the LRT exists, not having a car makes getting to work in Kanata, dropping kids off at school in Barrhaven, or managing daily errands incredibly difficult. The standard penalty for a first-time conviction is a strict one-year driving prohibition. However, the Ministry of Transportation Ontario (MTO) offers a vital lifeline to help you keep your job and your mobility.
This lifeline is called the Ignition Interlock Conduct Review Program. By participating, you agree to have a breathalyzer device hardwired into your vehicle’s ignition system. You must provide a clean breath sample before the car will start, and provide rolling samples while driving. There are two main pathways into this program: Stream A and Stream B. To ensure you meet the strict deadlines and eligibility requirements, it is highly advisable to consult with an Ottawa criminal defence lawyer immediately after your arrest.
Step-by-Step Process in Ottawa, Ontario
Entering the Ignition Interlock program requires careful coordination between the criminal courts and the MTO 📋. You must follow specific rules to avoid losing your eligibility. Here is how the process works.
Step 1: Determine Your Eligibility
Not everyone is eligible for the reduced suspension program. You must be a first-time offender under the Criminal Code. If your impaired driving charge involved an accident resulting in bodily harm or death, or if you were convicted of refusing to provide a breath sample, you are generally disqualified. Additionally, you cannot have a previous criminal driving conviction within the last ten years.
Step 2: Choose Stream A or Stream B
Your lawyer will help you decide which path is best 📖. Stream A requires you to plead guilty within 90 days of your charge. In return, you serve an absolute “hard” suspension of only 3 months, followed by 9 months of driving with the interlock. Stream B is for those who take longer to resolve their case or lose at trial. Under Stream B, you serve a 6-month absolute suspension, followed by 12 months with the interlock device.
Step 3: Register for the Back on Track Program
Before the MTO will grant your interlock licence, you must register for and begin Ontario’s mandatory remedial measures program, known as “Back on Track.” This involves an assessment, an educational or treatment workshop, and a follow-up interview. You can register for this program in Ottawa even while you are still serving your absolute suspension period.
Step 4: Install the Interlock Device
Once you have served your minimum absolute suspension and the MTO approves your application, you must lease the device from an MTO-approved provider. There are several authorized service centres across Ottawa where a certified technician will install the breathalyzer into your vehicle’s wiring. You will then take your installation certificate to ServiceOntario to officially reinstate your licence with the “I” (Interlock) condition.
How Much Does it Cost in Ottawa?
The privilege of driving early comes with significant financial costs. Participating in the Ignition Interlock program is entirely user-funded. Here is a breakdown of the estimated expenses in CAD as of March 2026:
- Back on Track Program: Registration for this mandatory MTO educational course costs a flat fee of $634 CAD.
- Interlock Installation: The approved service centre will charge an installation fee, typically around $150 CAD depending on your vehicle model.
- Monthly Lease and Monitoring: You do not buy the device; you lease it. Expect to pay about $100 to $130 CAD per month for the duration of your program, which covers calibration and data downloading.
- MTO Reinstatement Fee: ServiceOntario charges a standard $281 CAD fee to reinstate a suspended licence.
| Program Requirement | Estimated Cost (CAD) | Frequency |
|---|---|---|
| Back on Track Course | $634 | One-time fee |
| Device Installation | $150 | One-time fee |
| Device Lease & Calibration | $100 – $130 | Monthly |
How Long Does the Process Take?
For Stream A, you will face an absolute driving ban for 3 months, followed by 9 months of restricted driving with the device. For Stream B, the hard suspension is 6 months, followed by 12 months with the device. It is crucial to note that the “Back on Track” program takes up to 11 months to complete from start to finish. If you do not finish it, your licence will be suspended again, even if your interlock period is over ⌛.
Frequently Asked Questions (FAQ)
Can a family member drive my car if it has an interlock device?
Yes, anyone can drive your vehicle. However, they must also provide clean breath samples to start the car and while driving. Any failed test or violation recorded by the device is your responsibility, regardless of who was driving.
What happens if I blow a “warn” or fail a rolling test?
The device logs every test. If you record a blood alcohol concentration above the programmed limit (usually zero for this program), the car will not start. If you fail a rolling test, the vehicle’s lights will flash and horn will honk until you pull over. The MTO receives these logs and may extend your time in the program or suspend your licence again.
Do I have to buy the device outright?
No, you are not allowed to purchase the device. You must lease it through an MTO-authorized service provider to ensure it is properly calibrated and that the data is transmitted directly to the government without tampering.
Will the ignition interlock drain my car battery?
The device does draw a small amount of power from the battery, especially in the cold Ottawa winters to keep the sensors warm. If you drive your vehicle regularly, it is usually fine. If you leave the car sitting for a week or more in winter, you may need a battery tender.
What if I drive a commercial vehicle for work?
If your employer agrees, you can have an interlock device installed in a commercial vehicle. However, many employers will not permit this for liability and insurance reasons. You are strictly forbidden from driving any vehicle that does not have an approved interlock device while in the program.
