Legal principle
The rule from this case
When the Registrar of Motor Vehicles imposes an ignition interlock condition on a driver's licence, the affected driver has the right to appeal that decision to the Licence Appeal Tribunal. A central question in these appeals is whether the driver took reasonable, active steps — that is, exercised due diligence — to comply with or address the condition before or after it was imposed. The Tribunal examines the specific facts of each case to determine whether the driver's conduct met that standard. Simply being unaware of a condition, or failing to take proactive steps to understand one's obligations, is generally not enough to succeed on appeal. The driver must show that they genuinely did what a reasonable person would have done in the circumstances.

What this does not mean
This decision does not mean that every driver who faces an ignition interlock condition will automatically lose an appeal. The Tribunal assesses each situation individually, and the outcome depends heavily on the particular facts — including what steps the driver actually took and when. It also does not mean that a vehicle impoundment connected to an ignition interlock violation is always final. There may be procedural and substantive grounds to challenge both the condition and the impoundment, but those arguments must be supported by clear evidence that the driver acted responsibly and in good faith.
What Is an Ignition Interlock Condition in Ontario?
An ignition interlock condition is a requirement placed on a driver’s licence that forces the driver to use a breath-testing device connected to their vehicle’s ignition. In Ontario, the Registrar of Motor Vehicles has the authority to impose this condition in certain circumstances — most commonly following alcohol-related driving offences. Until the driver blows a clean breath sample into the device, the vehicle will not start.
These conditions can significantly affect a person’s daily life, including their ability to get to work, care for family members, or carry out basic errands. If the condition is violated, the consequences can include vehicle impoundment on top of the existing licence restriction.
Can You Appeal an Ignition Interlock Condition to the Licence Appeal Tribunal?
Yes — Ontario drivers can appeal an ignition interlock condition imposed by the Registrar of Motor Vehicles to the Licence Appeal Tribunal (LAT). The LAT is an independent adjudicative body that hears disputes about driver’s licences, vehicle impoundments, and related matters under Ontario’s Highway Traffic Act.
In Kunka v Registrar of Motor Vehicles, 2026 CanLII 68573 (ON LAT) (https://www.canlii.org/en/on/onlat/doc/2026/2026canlii68573/2026canlii68573.html), the Tribunal considered exactly this type of appeal — examining whether the driver had exercised due diligence in relation to the ignition interlock condition placed on their licence.
What Does ‘Due Diligence’ Mean in a Licence Appeal?
Due diligence, in this context, means taking all reasonable steps that a responsible person would take to understand and comply with their licence conditions. It is not enough to say you did not know about a condition or that you made an honest mistake.
The Tribunal looks at what the driver actually did — whether they sought information, followed up with the Ministry, complied with deadlines, and generally behaved as someone who took their obligations seriously. A driver who can demonstrate a genuine, documented effort to comply is in a much stronger position than one who simply claims ignorance.
What Happens If the Due Diligence Standard Is Not Met?
If the Tribunal finds that a driver did not exercise due diligence, the appeal is likely to fail and the ignition interlock condition — along with any associated vehicle impoundment — will stand. This can leave the driver facing an extended period of restricted driving privileges and the cost and inconvenience of retrieving an impounded vehicle.
The consequences are real and lasting. A failed appeal does not simply reset the clock — it confirms the Registrar’s original decision, and the driver must then comply with the condition going forward or face further penalties.
What Should You Do If Your Licence Has an Ignition Interlock Condition?
The most important step is to act quickly. There are strict deadlines for appealing decisions made by the Registrar of Motor Vehicles, and missing those deadlines can mean losing your right to challenge the condition entirely.
You should also gather any documentation that shows the steps you took — correspondence with the Ministry, records of any interlock device installation, and any other evidence of good-faith compliance. Our Ontario motor vehicle accident lawyers regularly advise clients on licence-related disputes and can help you understand whether you have grounds for an appeal.
How Does a Vehicle Impoundment Connect to an Ignition Interlock Violation?
In Ontario, a vehicle can be impounded when a driver is found to have violated an ignition interlock condition — for example, by driving a vehicle that is not equipped with the required device. The impoundment is a separate consequence from the licence condition itself, but both can be challenged at the LAT.
Understanding the connection between the two is important because appealing one does not automatically resolve the other. Each issue may need to be addressed on its own merits, with supporting evidence tailored to that specific ground of appeal. If you are dealing with both a condition and an impoundment, getting legal advice early can help you navigate both streams efficiently.

Practical Takeaways for Drivers Facing Ignition Interlock Conditions
- Act within the deadline. Appeals to the LAT must be filed within a specific window after the Registrar’s decision — do not wait.
- Document everything. Keep records of every step you took to comply with or inquire about your licence condition. This evidence is critical to a due diligence argument.
- Do not drive a non-equipped vehicle. If your licence has an interlock condition, driving any vehicle without the device — even once — can trigger an impoundment and make your appeal much harder.
- Understand that ignorance is not a defence. The Tribunal expects drivers to know and follow their licence conditions. Claiming you did not know is rarely sufficient on its own.
- Get legal advice before your hearing. The LAT process has its own rules of procedure, and presenting your case effectively requires preparation and knowledge of how the Tribunal weighs evidence.

FAQ
Frequently asked questions
You generally have a limited window — often 30 days — from the date of the Registrar's decision to file an appeal with the Licence Appeal Tribunal. Missing this deadline can mean losing your right to challenge the condition, so it is important to act quickly.
Not necessarily. Filing an appeal does not automatically stay or suspend the ignition interlock condition. You should confirm with the Tribunal whether a stay is available and whether you are permitted to drive while the appeal is being decided.
Evidence that shows you took active, reasonable steps to comply with your licence condition is most persuasive — such as records of device installation, correspondence with the Ministry, and any steps you took to address the issue promptly. The stronger your paper trail, the better your due diligence argument.
