Written by: Arian Borys, Licensed Insurance Broker (Level 3), Humberview Insurance Brokers The Ontario Ignition Interlock Program is a mandatory requirement for drivers to regain their driving privileges following an impaired driving conviction (also known as a DUI conviction) or multiple administrative suspensions.
Installing an ignition interlock device (a vehicle breathalyzer) ensures that a vehicle will not start if it detects alcohol on the driver’s breath. As of January 1, 2026, Ontario has significantly strengthened these laws, including doubling the “look-back” period for repeat offenders.
Many drivers researching the program search for terms such as ignition interlock Ontario, interlock installation, or ignition interlock Ontario cost as they try to understand the financial and legal requirements involved in getting their licence back.
In addition to the cost of installing and maintaining an ignition interlock device, drivers should also be aware that an impaired driving conviction can significantly affect their auto insurance. Many drivers need specialized DUI Insurance and premiums can increase substantially after a conviction. You can also learn more about how much insurance costs after a DUI in Ontario and how long the impact may last.
2026 Ignition Interlock Costs in Ontario
One of the most common questions Ontario drivers ask online is:
“how much does an ignition interlock device cost in Ontario?”
The total cost of participating in the program varies depending on the length of the requirement and vehicle type, but most drivers should budget between $1,500 and $2,200 per year.
When people search for ignition interlock Ontario cost, they are typically trying to understand the total yearly cost including installation, monthly device rental, and service appointments.
Some drivers specifically search for ALCOLOCK cost Ontario or Smart Start cost Ontario, since these are the two approved ignition interlock providers in the province. Fees are generally standardized between ALCOLOCK and Smart Start, though additional charges may apply for newer vehicles such as EVs or push-to-start systems.

| Monthly Lease (Device) | ~ $77.97 – $100.00 | Monthly |

Above prices are approximate and should be verified with your local installer and the Ministry for up to date pricing.
How Long is the Interlock Required? (The 10-Year Rule)
Starting in 2026, the Ontario Ministry of Transportation now uses a 10-year look-back period (previously 5 years) to determine if a driver is considered a repeat offender.
• 1st Offence: Minimum 1-year condition
• 2nd Offence (within 10 years): Minimum 3-year condition
• 3rd Offence (within 10 years): Minimum 6-year condition (post 10-year suspension)
• Administrative “Warn Range” (3rd time): Mandatory 6-month condition
Because the program can last several years, many drivers researching ignition interlock Ontario are primarily concerned with how long they must maintain the device in their vehicle.
Reduced Suspension: Stream A, B, and D
Drivers may be able to reduce their total licence suspension by participating in the Reduced Suspension with Ignition Interlock Conduct Review Program.
• Stream A (First-time offenders, guilty plea within 90 days)
3-month suspension followed by 9 months of interlock driving
• Stream B (First-time offenders, guilty plea after 90 days)
6-month suspension followed by 12 months of interlock driving
• Stream D (Repeat offenders within 10 years)
9-month suspension followed by 18 months of interlock driving

DUI Car Insurance and High Risk Insurance Requirements
While installing an ignition interlock device allows many drivers to regain limited driving privileges, it is only one part of getting back on the road after an impaired driving conviction. Drivers must also secure appropriate DUI car insurance, as many standard insurers will no longer offer coverage after a conviction. In many cases this means obtaining high risk car insurance from insurers that specialize in covering drivers with previous convictions or licence suspensions.
