After an impaired driving conviction in Ontario, can you drive sooner with an ignition interlock?

Yes, in many cases, if the conviction is a first or second alcohol-impaired driving offence under the Criminal Code. Ontario's Reduced Suspension with Ignition Interlock Conduct Review Program can cut a first offender's one-year suspension to as little as 3 months, followed by at least 9 months driving with an interlock, if they plead guilty and are sentenced within 90 days of the offence. Drug-impaired cases and offences causing bodily harm or death are excluded.

A conviction for impaired driving or over 80 normally means a one-year provincial suspension for a first conviction and three years for a second within 10 years. The reduced suspension program shortens that time off the road in exchange for strict conditions: an approved ignition interlock device, the Back on Track remedial program and clean monitoring results. This page sets out the streams, who qualifies, the timelines and what can go wrong. For how these charges are defended in the first place, see our main page on impaired driving in Ontario.

How does the reduced suspension program work, step by step?

1. Conviction and the court's order. At sentencing, the court must make a driving prohibition order (Criminal Code s. 320.24(1)). Under section 320.24(10), a person cannot be registered in an interlock program until a minimum absolute prohibition period ends: for a first offence, any period the court fixes; for a second, at least three months after sentence; for later offences, at least six months.
2. The information package. Eligible drivers are sent an information package by the Ministry of Transportation with the entry requirements, application instructions, the mandatory suspension and interlock periods and the timelines to meet.
3. The Back on Track assessment. You complete the assessment component of the Back on Track remedial measures program. A second-time offender with an unfinished remedial requirement from an earlier conviction must complete the whole program first.
4. The interlock lease. You sign a lease agreement with one of Ontario's approved ignition interlock service providers. The province lists Smart Start Canada and ALCOLOCK Canada.
5. Clearing everything else. Before entering, you must be reinstated from any other suspension, such as for unpaid fines or a medical reason, have paid all outstanding fees or penalties, and have every other suspension and prohibition expired or removed.
6. Conditional reinstatement and installation. Your licence comes back with an interlock condition, and the device must be installed within 30 days (O. Reg. 287/08, s. 26).
7. Monitoring. Every 60 days you return to the service provider so the device's data can be downloaded and the device calibrated.
8. Exit. You leave the program when you have completed Back on Track, which the province says can take 11 months, and the final data download shows no violations or performance failures.

Section 320.18(2) of the Criminal Code is what makes this legal: it is not the offence of driving while prohibited if you are registered in your province's alcohol ignition interlock program and comply with its conditions. Ontario's regulation says its program is established for that purpose (O. Reg. 287/08, s. 23).

What are the three streams?

Two notes on the province's table matter in practice. The court may increase the suspension period. And the interlock period depends on the prohibition the court ordered: it will not end before the driving prohibition expires. So a longer prohibition at sentencing means a longer time with the device, whatever the stream minimum says.

For Stream A, the province adds a deadline: within three months of sentencing, you must complete both parts of the application, the remedial measures assessment and the lease with a service provider. It advises registering for the remedial program immediately on conviction and asking for an assessment.

Who is eligible, and who is not?

According to the province, you may be eligible if your licence was suspended for one or three years because of an alcohol-impaired driving conviction under the Criminal Code and you are a first-time or second-time offender as determined by the Highway Traffic Act. You are not eligible if any of these apply:

• the offence involved impairment by drugs, or by drugs and alcohol together;
• you were convicted of a Criminal Code offence where bodily harm or death was caused;
• you were convicted of driving while disqualified under the Criminal Code within 5 years before the impaired conviction for a first offender, or 10 years for a second offender;
• a court order denies you authorization to drive with an ignition interlock device during the prohibition;
• you already had an ignition interlock condition on your licence on the date of the offence; or
• you were previously granted a reduction to 10 years of an indefinite licence suspension.

The regulation behind the program says the same in more technical terms, including that the court's order under section 320.24(10) must not exclude you from the program (O. Reg. 287/08, s. 25(1)(b)(ii)). It ties eligibility to suspensions for the offences listed in Highway Traffic Act s. 41(1)(c), a list that includes a refusal under s. 320.15, but the ministry's page describes the program as being for alcohol-impaired driving convictions, so a person convicted of refusal should confirm with the ministry before relying on it. Our page on the penalties for refusing a breath or drug test covers that charge.

What happens if you break the rules?

The program is strict, and the province spells out the consequences. Violations during the installation period lead to removal from the program and a new suspension. They include not installing the device within 30 days of conditional reinstatement, removing it without authorization, tampering with it, driving a vehicle without an approved device, missing an appointment with the service provider, and a new Criminal Code driving conviction.

If you are removed, you face the full suspension and interlock requirements you would have had without the program, with credit for the suspension already served, and you must complete the remedial program before reinstatement with an interlock condition of at least 1 year for a first offender or 3 years for a second offender.

Performance failures are treated differently. Blowing over the 0.02 limit, or missing a random breath test the device asks for while you drive, extends the installation period: by 3 months for first-time offenders if it happens in the last 3 months, and by 6 months for second-time offenders if it happens in the last 6 months. A roadside administrative suspension at any point during the installation period adds 3 months. Our page on warn-range suspensions explains one of the roadside suspensions that can trigger that extension.

More generally, the province says a conviction for driving without the device or tampering with it carries a fine of $200 to $1,000 for a vehicle that is not a commercial vehicle, and a breach of an interlock condition imposed after a Criminal Code conviction can lead to an impoundment of 45 days for a first offence, 90 days for a second and 180 days after that.

What if you do not enter the program?

Then you serve the full suspension, complete the remedial measures program before reinstatement, which the province says can take up to 11 months, and drive with an interlock condition for at least 1 year (first offender) or 3 years (second offender). To have the condition removed, you submit a Substance Use Assessment form, which the ministry mails 6 months before the condition removal date, and complete a final appointment with the service provider.

For offences on or after July 1, 2026, the rules tightened. You must install an interlock after a conviction. If you install it within 30 days of reinstatement and stay in good standing, the minimum interlock period can be 9 continuous months for a first offender and 2 continuous years for a second (O. Reg. 287/08, s. 22.2(2) and (6)). And once the interlock condition comes off, a "P" condition of at least six months applies, meaning no alcohol and no drugs in your system when you drive. For older offence dates, a driver who chooses not to install the device simply cannot drive until the condition is removed.

The roadside 90-day suspension and the conviction suspension are separate steps; our page on what happens to your licence and car right away explains how they fit together.

What changes the answer?

• Timing of the plea. Streams A and D require a guilty plea and a conviction, sentence and prohibition order within 90 days of the offence date (O. Reg. 287/08, s. 25(3) and (6)).
• Whether this is a first or second offence. The Highway Traffic Act counts only convictions within 10 years for the longer suspensions (s. 41(3)). A third conviction within 10 years means an indefinite suspension, which the province says may be reduced after 10 years if you meet certain criteria.
• The court's order under section 320.24(10). It can fix a minimum absolute prohibition period, and the regulation's earliest entry dates run from the later of that period and the program's own waiting time (O. Reg. 287/08, s. 25(5)).
• The length of the prohibition. The interlock period does not end before the prohibition expires.
• Alcohol or drugs. Any drug involvement takes the case out of the program.
• Your record of interlock use. Failures in the final months add time, and violations remove you from the program.

A worked example

For example, imagine Babak, a contractor from Thornhill who needs to drive to job sites. He is charged with over 80 in Toronto after a work dinner, with no drugs involved and no accident. It is his first offence. His case is in the Ontario Court of Justice at 10 Armoury Street; our guide to the Toronto courthouse at 10 Armoury Street explains where it runs.

After his lawyer reviews the disclosure and discusses the case at a judicial pre-trial, Babak decides to plead guilty, and he is sentenced on day 75 to the minimum fine and a one-year prohibition, with nothing in the order excluding the interlock program. That fits Stream A. He registers for Back on Track at once, completes the assessment, and signs an interlock lease within three months of sentencing. If the ministry approves him, his suspension could be as short as three months; he would then pay the reinstatement fee, have the device installed within 30 days, and drive with it for at least nine months, a period that cannot end before his one-year prohibition expires. Because his offence date is after July 1, 2026, a six-month "P" condition would follow.

If Babak had gone to trial instead, Stream A would not be open to him, because it requires a guilty plea; if he were convicted at trial, Stream B would be the route to consider. This is a hypothetical walk-through, not a prediction of any result.

What mistakes do people make?

1. Missing the 90-day window by accident. Adjournments for routine reasons can push sentencing past the date that Streams A and D depend on. Our page on criminal disclosure explains why early dates are often adjourned.
2. Pleading guilty only to reach a stream. A guilty plea admits the offence and ends any defence, so the decision should come after the disclosure has been reviewed.
3. Waiting to register for Back on Track. Stream A requires the assessment and the lease within three months of sentencing.
4. Forgetting the court order. An order that denies interlock authorization, or a long absolute prohibition period, changes everything, so it should be addressed at sentencing.
5. Treating a 0.02 reading as harmless. In the final months of the installation period it extends the program.
6. Assuming a refusal or drug case qualifies. Drug cases are excluded, and refusal cases should be confirmed with the ministry.

What to do this week

1. Write down your offence date and count 90 days from it.
2. Check whether drugs or an accident are alleged. Either can rule the program out.
3. Gather any earlier driving record. Earlier convictions within 10 years change the stream.
4. Read the Back on Track and interlock pages on ontario.ca so you know the steps before sentencing.
5. Ask your lawyer about the sentencing order, including the prohibition length and any order under section 320.24(10).
6. Plan for costs. The province says drivers pay all installation and maintenance costs, and the service provider gives its fees when you register.

Frequently asked questions

Does the ignition interlock let me drive any car?

No. With an interlock condition you may drive only a vehicle equipped with an approved device. The province says vehicle owners who knowingly let a person with an interlock condition drive their vehicle can also be charged.

How does the device work?

You blow into it before the engine starts, and the vehicle will not start above the preset 0.02 limit. While you drive, it asks for random breath samples; a missed sample or a high reading triggers a warning, records the event and sets off alarms until you turn off the ignition.

What does the program cost?

The province does not publish a price. Drivers pay all installation and maintenance costs, and the service provider sets out its fees at registration. The licence reinstatement fee, listed by the province at $281, applies on top.

Will I need to retake road tests?

Ontario's reinstatement page says that if a full licence has been suspended for more than one year, you need tests: an eye test after 1 to 3 years, and a knowledge test, an eye test and two road tests after 3 to 10 years.

Does a discharge avoid all of this?

No. The provincial suspension applies to a discharge as if it were a conviction (Highway Traffic Act s. 41(5)). Our page on what each outcome means in Ontario explains discharges more generally.
