What is the Ignition Interlock Remedial Measures Program?

Besides the fines and driver’s licence suspensions to which you would be subject if caught driving impaired or with a blood alcohol concentration above either the legal limit (“over 80”) or over the administrative limit (“over 50”), there are even more DUI consequences in Ontario of which you should be aware. The additional punishments are meant to improve an offender’s future driving behaviour.

The law in Ontario provides for two levels of offences based on Blood Alcohol Level (BAC).The “warn range” is BAC in the range of 0.05 and 0.08 mg/ml. The “prohibited range” indicates that BAC is above 0.08 mg/ml and will produce more serious financial and legal consequences. Having a BAC in the prohibited range is a criminal offence and if convicted, will leave you with a criminal record. Similarly, if you are convicted of “impaired” driving, regardless of your BAC, you will have a criminal record.

Interlock Device Installation

An ignition interlock device is used to ascertain the presence of alcohol in the driver’s body and to prevent a motor vehicle from being started if the BAC in the driver’s body exceeds zero. Mandatory interlock device installation is an additional punishment under the Highway Traffic Act (HTA) for drivers convicted of impaired driving or convicted of driving with a BAC “over 80” (BAC: >0.08), as defined under the Criminal Code, or found to be driving within the warning range, which means having a BAC of “over 50” “but under 80” (BAC: 0.05 to 0.08) as defined under the HTA.

Conduct Review Programs (Reg. 287/08)

In Ontario, there are programs for alcohol or drug involved convictions under the HTA, designed to improve an offender’s behaviour and accountability. If a police officer finds, upon taking a breath sample from you that you were driving with a BAC “over 50,” you will have your driver’s licence suspended immediately at roadside and will face an administrative monetary penalty of $150. If it is not your first such offence, you will also be required to participate in some or all of a conduct review program. In Ontario, the conduct review programs consist of a remedial measures program (Back on Track) and an ignition interlock device program. (Ignition Interlock Program).

Back on Track

Back on Track is Ontario’s remedial measures program for impaired drivers and drivers convicted of “over 80” (BAC>0.08). It is operated by the Centre for Addiction and Mental Health on behalf of the Ontario Ministry of Transportation. Back on Track consists of the following three components:

  • Preliminary Assessment
  • Remedial Education Program (8 hours) or Treatment program (16 hours),
  • Follow-up Interview

Criminally convicted drivers must complete all three components of the Back on Track program before the licence suspension expires and satisfy all other requirements set by the court in order to have their licence reinstated. Convicted impaired drivers should register immediately upon conviction as the program can take up to 11 months to complete.


If you were suspended for having a BAC “over 50” (between 0.05 and 0.08) and this is your second such offence, you are required to complete the Education Program (8 hours). If this is your third such offence you must complete the Treatment Program (16 hours). Beyond three such offences, you will also be subject to a mandatory medical evaluation. Drivers will have 120 days from the start of the suspension period to complete the education course and 180 days to complete the treatment course.

Ignition Interlock Program

If you are convicted of a drinking and driving offence under the Criminal Code, or if it is your third or more time in a five-year period being suspended for having a BAC between 0.05 and 0.08, you will be subject to Ontario’s Ignition Interlock Program.

After serving the provincial sanctions, including licence suspension, fine and a mandatory remedial measures program (Back on Track), all drivers convicted of drinking and driving Criminal Code offences, who are eligible to have their driver’s licence reinstated, will have an ignition interlock condition placed on their Ontario driver’s licence.

  • First-time offenders will have an ignition interlock condition on their licence for a minimum of one year.
  • Second-time offenders will have the condition for a minimum of three years.
  • Third-time offenders will have the condition on their licence indefinitely if it is reinstated after a minimum 10-year suspension.

The program does not apply to fourth-time offenders because their licence will never be reinstated. Drivers who are suspended for registering a BAC between 0.05 and 0.08, three or more times in a five-year period between each offence, will have an ignition interlock condition placed on their licence for six months after serving their 30-day licence suspension.

Reduced Suspension with Ignition Interlock Conduct Review Program

This program became effective on August 3, 2010, and enables drivers who were convicted of Criminal Code drinking and driving offences for the first time, to reinstate their driver’s licence sooner by installing an approved ignition interlock device in their vehicle. Such drivers must meet the following criteria:

  • driver’s licence has been suspended for a period of one year as a result of a first-time conviction on or after August 3, 2010 of a drinking and driving offence, or refusal to blow into a roadside screening device or an Approved Instrument;
  • must complete the assessment component of Back on Track prior to early licence reinstatement;
  • the circumstances of the offence did not involve impairment by drugs or a combination of drugs and alcohol;
  • not convicted of an offence where bodily harm or death is caused;
  • not convicted of a “driving while disqualified” offence within the five years preceding their drinking and driving conviction;
  • not subject to a court order denying them the authorization to drive with an ignition interlock device during the prohibition period;
  • not subject to an ignition interlock licence condition on the date of the offence;
  • not previously been granted a reduction to 10 years of an indefinite licence suspension; and
  • sign a lease agreement for an ignition interlock device with the approved ignition interlock service provider.

Before successfully entering this program, eligible drivers must pay all outstanding fees and all other active suspensions must have expired or been removed.

First-time offenders who are not eligible for or who choose not to participate in the program will be subject to the standard penalties under the Highway Traffic Act: for the first conviction, one year suspension without reduction, plus one year of having the interlock condition on their driver’s licence.

Drivers participating in the program will be in one of two streams. Drivers in Stream “A” will have their licence suspension period reduced to a minimum of three months, followed by a minimum nine-month ignition interlock period. Drivers in Stream “B” will have a minimum licence suspension of six months and a minimum interlock period of 12 months. Drivers eligible for the program that do not meet all of the requirements to enter the program in Stream “A” (for example do not plead guilty within 89 days of the offence) may be eligible to enter the Ignition Interlock Program in Stream “B.”

SuspensionInterlock Device InstallationTotal Period of Time
Standard Penalty with Interlock1 year1 year2 years
Stream A3 months9 months1 year
Stream B6 months12 months1.5 years

Drivers who are eligible for the program will receive an individualized information package from the Ministry of Transportation with information on how to meet the requirements for entry into the program in one of the two streams. The package will include the application instructions, will identify the mandatory periods of suspension and interlock installation, and provide timelines that must be met to enter the program.

Mr. Marchand is an amazing lawyer. He is very personable and professional. My case was a very long and drawn out case, but Mr. Marchand always kept up with everything and I was always well informed. I really appreciated that he would take the time to fully explain his thought process/strategy and was never condescending. Even though this was a stressful time, Mr. Marchand made it a great experience and took care of more

Once again amazing ! I am writing this review as I always refer my friends to this firm. THEY ARE THE BEST ! My friend was pulled over at the us border on a random check and in turn got charged with a refusal. My friend did not know that refusing to take a breathalyzer was a criminal offence. In fact as soon as he realized it he asked the officers to take it but they refused him. In turn he was charged with a refusal. Aitken Robertson specializes in DUI and cases such as this.. so it was an immediate call to them that i put in for him. Right then and there they took over. As usual, they offered a payment plan and of course they took care of everything all the pre-trial meetings etc. Justin was the laywer for him and not only is he the MOST thorough he is the most out for justice. He found the errors that the officers made and he used it to my friends advantage. He went above and beyond to find the best resolution with the crown. He went above and beyond to give my friend all his options. And the best part is that NO CRIMINAL CHARGES. It was reduced basically down to a speeding ticket as a result of Justins hard work. The whole firm is stellar. They take time to go through your disclosure to confirm any and all details are correct.The justice system is a corrupted one and im thankful these lawyers know how to find a way to help us through that. Justin once again did an amazing job. Susan at the firm is great she helps out with payment plans etc. Brenda is great. Robert of course its just a great team of laywers. Do not go anywhere else ! I will recommend them time and time more

When my daughter's boyfriend had a problem I looked up Jordan Tekenos-Levy. Jordan did an amazing job defending this young man. He showed compassion and care in a very sensitive issue. Jordan is a great lawyer, he fights hard for his clients and ensures their loved ones are kept in the loop during the entire process. He is honest and doesn't sugar coat the situation. I would highly recommend his services. We owe him a huge debt of gratitude and I wish him all the best in the more

I was falsely accused of a crime and I sought out representation. I did not know exactly where to go, I was in a panic as I've never seriously run afoul with law enforcement. Mr. Nathan Baker and his staff were assigned to my case, and I am thankful that they were. Knowing I was innocent I still was worried about how everything was going to play out as I wondered 'how could this even be happening'. Mr Baker and his staff helped walk me through the court process that was completely unfamiliar to me, besides what Id seen on television. It was a two year process, and every step of the way all my questions and inquisitions were answered and put at ease. I give this Firm my full endorsement, they believed in me, supported my case and followed through on every detail pertaining to it, and defended me to a correct Not Guilty verdict. For that I will be forever grateful. I've never had the need for an attorney to represent me before the false accusation, and I hope I never need it again. But if I do, I'd want this firm to represent more
