Impaired Driving (DUI) Charges in Ontario: Penalties Explained

Two Sets of Penalties, One Very Serious Charge
A DUI charge Ontario drivers face isn’t governed by a single law — it’s governed by two, running at the same time. The federal Criminal Code sets out criminal penalties, while Ontario’s Highway Traffic Act adds its own administrative consequences, often starting before a single court date has even been scheduled. Understanding both systems is the first step to understanding what you’re actually facing.
This guide breaks down impaired driving charge Ontario penalties in plain terms — what the law requires, how the numbers change with a prior record, and what recent provincial changes mean for anyone charged today.
What Counts as Impaired Driving Under Canadian Law
Section 320.14 of the Criminal Code sets out several distinct ways a person can be charged: operating a vehicle while impaired by alcohol or drugs, operating with a blood alcohol concentration at or above 80 milligrams per 100 millilitres of blood (commonly called “over 80”), or refusing a lawful demand to provide a breath or blood sample. Refusal is treated just as seriously as a failed test, and carries the same — or in some cases higher — minimum penalties.
The Criminal Penalties: What a Conviction Actually Costs
Under section 320.19 of the Criminal Code, the drunk driving penalty Ontario courts impose depends heavily on whether it’s a first offence or a repeat one.
Offence | Minimum Penalty Under the Criminal Code |
|---|---|
First Offence | A fine of at least $1,000, plus a minimum one-year driving prohibition |
Second Offence | A minimum of 30 days in jail, plus a minimum two-year driving prohibition |
Third or Subsequent Offence | A minimum of 120 days in jail, plus a minimum three-year driving prohibition |
These are minimums, not caps — the maximum sentence on indictment can reach 10 years’ imprisonment. Higher blood alcohol readings also increase the mandatory minimum fine on a first offence, and refusing to provide a sample carries a higher minimum fine than a standard first offence as well.
The Provincial Side: Ontario's Administrative Penalties
On top of the criminal process, Ontario applies its own immediate consequences under the Highway Traffic Act — and these apply whether or not you’re ultimately convicted. As of January 1, 2026, Ontario significantly expanded these penalties, including:
- Longer roadside suspensions for warn-range results (blood alcohol between 50 and 80 mg%), now starting at 7 days for a first offence and 14 days for a second
- An administrative driver’s licence suspension of up to 90 days, separate from any criminal outcome
- Vehicle impoundment, commonly for 7 days on a first offence
- A doubled look-back period, now 10 years instead of 5, meaning past incidents count against you for much longer
- Mandatory participation in the CAMH “Back on Track” remedial program, required before a suspended licence can be reinstated
These provincial penalties are separate from, and in addition to, whatever happens in criminal court — which is part of why so many people are caught off guard by how quickly the consequences of an impaired driving charge Ontario penalties bring can start to stack up.
The Ignition Interlock Program
Following a conviction, many drivers are required to install an ignition interlock device — a breath-testing unit connected to the vehicle’s ignition — for a set period before full driving privileges are restored. This requirement operates alongside the driving prohibition and remedial program requirements, and skipping any step can delay reinstatement of your licence well beyond the minimum suspension period.
What a DUI Conviction Means Beyond the Penalties Themselves
A conviction creates a permanent criminal record in Canada, which can affect employment, professional licensing, and eligibility for certain volunteer or regulated positions. Auto insurance premiums typically rise sharply as well, often for several years after the conviction, on top of the fines and legal costs already incurred. A criminal record can also be a factor in future travel outside Canada, so it’s worth discussing your specific situation with a lawyer if travel is a concern.
Common Defences to an Impaired Driving Charge
Impaired driving cases often turn on procedure as much as on the facts. Defences that come up regularly include:
- Challenging the legality of the traffic stop — whether police had proper grounds to detain you
- Questioning breath test procedure and timing — including whether the Approved Instrument was used and calibrated correctly
- Charter violations — such as delays in providing access to a lawyer after arrest
- Disputing the accuracy of officer observations — particularly in borderline impairment cases
A defence built around these issues can lead to a reduced charge, a withdrawal, or an acquittal, even when a breath test result exists.
What to Do If You've Been Charged With Impaired Driving
- Comply with the roadside process, but say as little as possible beyond what’s legally required
- Note the time, location, and circumstances of the stop as soon as you’re able to
- Avoid discussing the details of your arrest with anyone other than your lawyer
- Contact a criminal defence lawyer immediately, given how quickly licence suspension timelines begin

FAQ
What are the penalties for a first-time impaired driving charge in Ontario?
A minimum $1,000 fine and a one-year driving prohibition under the Criminal Code, plus separate provincial licence suspension, vehicle impoundment, and remedial program requirements under Ontario’s Highway Traffic Act.
Do you go to jail for a first DUI in Ontario?
Not automatically. A first offence carries no mandatory minimum jail sentence, though a judge retains discretion to impose one in cases involving aggravating factors.
What’s the penalty for a second or third DUI offence?
A second offence carries a minimum 30 days in jail; a third or subsequent offence carries a minimum 120 days, with driving prohibitions increasing to two and three years respectively.
Is refusing a breathalyzer treated differently than failing one?
No. Refusing a lawful demand for a breath or blood sample carries the same, or in some cases higher, mandatory minimum penalties as a standard impaired driving conviction.
How long can my licence be suspended before I even go to court?
Ontario’s administrative licence suspension can last up to 90 days, and this applies immediately, regardless of the outcome of any criminal charge.
Can a DUI charge be reduced or dismissed?
Yes, in some cases. A lawyer may be able to challenge the legality of the stop, the accuracy of the breath test, or procedural errors that occurred during the arrest.
Does a DUI conviction stay on my record permanently?
Yes, unless you apply for and receive a record suspension (formerly known as a pardon) once you’re eligible. Until then, the conviction remains on your criminal record and can affect background checks for employment, licensing, or volunteering.
