DUI Charges in Ontario: A Complete Guide to Impaired Driving, Over 80, Refusal, and Other Offences
Getting charged with a DUI in Ontario can change your life overnight, because impaired driving is treated with the utmost seriousness across Canada. While many people think of DUI as simply “drunk driving,” the reality is that the laws actually cover a wide range of offences. These include driving while impaired by alcohol or drugs, having a blood alcohol concentration over the legal limit (known as “Over 80”), refusing a breath test, and more. Significantly, each offence carries its own set of penalties and is prosecuted under the Criminal Code of Canada, which applies across all provinces and territories, including Ontario. That means even a first-time charge can lead to a criminal record and major consequences.
Many drivers aren’t fully aware of how broad Ontario’s impaired driving laws really are. You don’t have to be falling-down drunk to be charged. In fact, even if you feel fine to drive, you could still be over the legal limit or impaired enough to face charges. There are also situations where refusing to cooperate with a police demand—like a roadside breath test—can lead to charges that may carry penalties similar to or even greater than impaired driving, depending on the circumstances.
Understanding the full scope of DUI-related offences is essential, not just for those who’ve been charged but for anyone who gets behind the wheel. A conviction's repercussions can have a lasting impact on your life. Beyond the fines and potential jail time, you may face a suspension or revocation of your driver’s licence under both federal and Ontario's provincial laws, a drastic increase in insurance premiums, or even hurdles when job hunting or crossing international borders.
This guide will walk you through the different types of DUI charges in Ontario, what each one means, and what you should expect if you’re dealing with one. Whether you've been charged or simply wish to be prepared, understanding your rights and the legal process is the crucial first move in safeguarding yourself.
DUI in Ontario: Legal Overview
When discussing DUI, it's important to understand that the term refers to "Driving Under the Influence," but the actual charges fall under the impaired driving provisions of the Criminal Code of Canada. That means impaired driving isn’t just a traffic issue—it’s a criminal offence. There are several sections of the law that deal with DUI-related charges, depending on the situation. It’s not all about alcohol either. Drugs, refusal to cooperate, and even a person’s legal status behind the wheel can impact the charges and penalties.
To delve deeper, let's examine section 320.14 of the Criminal Code, which covers impaired operation. This includes operating a vehicle while affected by alcohol, drugs, or a mix of both. Then there’s section 320.15, which deals with refusing a lawful demand for a breath sample, blood sample, or other bodily substances. Refusal to comply can result in a criminal charge with penalties comparable to those for impaired driving, so it’s treated just as seriously in court.
For more aggravated situations, the law intensifies the repercussions. If impaired driving causes bodily harm or death, the charges escalate significantly—to “operation causing bodily harm” or “operation causing death” under sections 320.14(2) and 320.14(3) of the Code, which carry much more severe penalties. Repeat offenders also face tougher consequences.
In addition, Ontario has zero-tolerance rules under the Highway Traffic Act for young drivers, novice drivers, and commercial drivers. For these groups, any trace of alcohol or drugs detected in their system is enough to trigger penalties, irrespective of whether they are within the legal limits applicable to other fully licensed drivers.
Beyond facing criminal charges, there are also administrative consequences imposed by Ontario’s Ministry of Transportation. These include immediate roadside licence suspensions, vehicle impoundment, and monetary fines. These can happen before any court date, and even before you’re officially convicted. So, even a first-time offence can have an instant impact on your driving record and day-to-day life.
DUI Offences in Ontario: What Each Charge Really Means

In Ontario, impaired driving laws are strict and designed to keep roads safe for everyone. DUI charges can significantly impact your life, with potential consequences ranging from fines to jail time. Here are the core DUI-related offences in Ontario that drivers should be aware of:
Impaired Driving (Alcohol or Drugs) – Section 320.14(1)(a)
This charge is laid when your ability to drive is compromised due to alcohol or drugs. It doesn't matter what your blood alcohol level (BAC) is; if you’re impaired, you can be charged. Officers determine impairment through physical tests, observations, and sometimes expert opinions. It's a serious offence with penalties that can include licence suspensions and fines.
Over 80 – Section 320.14(1)(b)
You can be charged with this offence if your BAC is equal to or exceeds 80 milligrams of alcohol in 100 millilitres of blood. This is true even if you don't show visible signs of impairment. Unlike impairment charges, this is based strictly on your BAC level. Failing a breath test typically leads to immediate licence suspensions and fines.
Impaired by Drug or Combination – Section 320.14(1)(c)
This charge comes into play when impairment is due to a drug or a combination of alcohol and a drug. Officers use various tools like roadside tests, Standard Field Sobriety Tests (SFSTs), Drug Recognition Evaluations (DREs), and observations to establish this. The penalties are similar to those for alcohol impairment and often involve licence suspensions and fines.
Refusal or Failure to Comply – Section 320.15
If you refuse or fail to provide a breath, blood, or urine sample when lawfully demanded by police, you could face this charge. Compliance with these tests is mandatory under the Criminal Code, and refusal is treated as seriously as DUIs involving impairment. You could see immediate consequences such as licence suspensions and fines, and a criminal record upon conviction.
Care and Control While Impaired
This charge applies if you’re found in care or control of a vehicle while impaired, even if you aren’t actively driving. "Care and control" can mean sitting in the driver’s seat while the car is parked or having the keys in your possession. Courts will assess whether there was a realistic risk of the vehicle being set in motion. Even without actual driving, the penalties are on par with driving while impaired.
Impaired Driving Causing Bodily Harm or Death
This is one of the most severe DUI charges, applied when impaired driving results in injury or death. The legal system treats these cases with amplified seriousness, reflected in harsh penalties, which could include long-term imprisonment. It underscores the catastrophic consequences that impaired driving can have on lives.
Repeat Offences
If you’ve been convicted of impaired driving before, repeat offences lead to tougher penalties. These may include extended licence suspensions, mandatory minimum jail sentences, and longer driving prohibitions. Over time, these harsher penalties aim to dissuade repeat behavior, protecting road safety for all.
Understanding these charges and their implications is crucial for every driver in Ontario, not just for personal awareness but also for contributing to safer roads. Following the law can save lives and prevent the severe repercussions associated with these offences.
Penalties and Consequences of DUI in Ontario

Driving under the influence is a serious offence in Ontario with severe penalties. These penalties are designed to discourage impaired driving and ensure public safety. At the same time, the aim is to be strict with offenders to reduce the number of accidents caused by impaired drivers.
Let’s break down the implications of a DUI in Ontario:
Immediate Roadside Penalties
When you're stopped and suspected of impaired driving, the police can enforce immediate roadside penalties. One such penalty is a 90-day Administrative Driver’s Licence Suspension (ADLS). This means you can't drive for three months. Your vehicle may also be impounded for seven days. Additionally, the ADLS applies if you fail a breath test, refuse a demand, or are charged with a criminal impaired driving offence. These measures are immediate and apply even before a court hearing, serving as a strong deterrent against DUI.
Fines
If you're caught driving under the influence, you can expect to pay hefty fines. The mandatory minimum fine for a first offence is $1,000, but this can increase significantly depending on your blood alcohol concentration (BAC) or if there are aggravating circumstances. These financial penalties reflect the seriousness of the offence and aim to deter individuals from impaired driving.
Driving Prohibition
In addition to immediate penalties, courts can impose a driving prohibition. For a first offence, the prohibition is at least one year under the Criminal Code. A second offence may result in a minimum two-year prohibition, while further offences can lead to longer bans. These prohibitions are crucial for keeping impaired drivers off the roads.
Jail Time
Jail time is a real consequence for those who continue to drink and drive. While first-time offenders usually do not receive jail time unless aggravating factors are present, a second offence carries a mandatory minimum of 30 days in jail, and a third or subsequent offence carries a minimum of 120 days. This highlights the escalating severity of penalties for repeat offenders.
Mandatory Education and Treatment Programs
After a DUI conviction, individuals in Ontario are required to complete Ontario’s Remedial Measures Program in order to have their licence reinstated. These programs address the underlying issues related to impaired driving and provide education on the effects of alcohol and drugs. Some participants may also be required to attend treatment or counselling sessions.
Long-term Impact
A DUI conviction doesn’t end with your court date. It can affect many aspects of your personal and professional life long after your sentence is complete.
Criminal Record
A DUI conviction in Ontario results in a criminal record under federal law, which can have long-lasting effects. This record can impact your ability to find employment, as many employers conduct background checks. It can also affect your personal life, as having a criminal record carries a stigma. A record suspension (formerly called a pardon) is possible after a waiting period, but the process is time-consuming and not guaranteed.
Increased Insurance Rates or Cancellation
Being convicted of a DUI can result in a noticeable increase in car insurance costs. This happens because insurance providers classify drivers with a DUI as high risk, which typically leads to much higher premium charges. In some cases, insurance providers may cancel your policy altogether. This financial burden adds another layer of deterrence to impaired driving.
Employment and Immigration Concerns
Having a DUI on your record can limit your career opportunities. Some professions—especially those requiring driving, working with vulnerable persons, or handling sensitive information—may be closed to individuals with a criminal record. Additionally, for non-citizens, a DUI is considered a serious criminal offence and can affect admissibility, permanent residency applications, or citizenship eligibility.
Border Crossing/Travel Restrictions
A criminal record from a DUI conviction can also affect your ability to travel internationally. For example, the United States may deny entry to individuals with DUI convictions, particularly if there are multiple offences or aggravating factors. This often-overlooked consequence can affect both personal and professional travel plans.
What to Expect After Being Charged
Being charged with impaired driving can be overwhelming and confusing, especially if it’s your first encounter with the legal system. Understanding what happens next—from the roadside stop to your first court appearance—can help you stay informed and make better decisions.
This section outlines the key stages in the process so you know what to expect and how to protect your rights.
What Happens at the Roadside
First, when you're pulled over by police, they’ll ask for your driver’s licence, vehicle registration, and insurance. If they suspect impairment, they may ask you to exit the vehicle. You might be asked to perform Standard Field Sobriety Tests (SFSTs)—simple tasks like walking in a straight line or following an object with your eyes. These help assess coordination and attention.
In many cases, the officer will also administer a roadside Approved Screening Device (ASD) test (a preliminary breath test). If you fail this test or refuse it, you're subject to immediate licence suspension and possible arrest. While cooperation is important, you also have the right to remain silent and the right to contact a lawyer.
Arrest, Breathalyzer, and Police Procedures
If the officer has reasonable grounds to believe you’ve committed an impaired driving offence, you may be arrested and taken to a police station. There, you may be asked to provide further samples—usually through an evidentiary breathalyzer or blood test conducted under controlled conditions.
These results are admissible in court and form part of the evidence against you. You have the right to contact a lawyer immediately upon detention, and it is strongly recommended that you exercise this right before answering any questions.
First Court Appearance and Disclosure
After your release, you’ll receive a court date. Your first court appearance is often referred to as a first appearance, not an "arraignment" as in the U.S. At this hearing, you’ll receive the formal charges and may be asked to enter a plea, although this sometimes happens later.
You’ll also receive disclosure—the evidence the Crown (prosecutor) has against you, such as police notes, test results, and video recordings. It’s essential to have legal representation at this stage. A lawyer can review the disclosure, explain your options, and start building your defence.
Bail Conditions or Driving Restrictions
In most DUI cases, you’ll be released from custody with conditions, rather than held on formal bail. However, depending on the nature of the offence, the court may impose release conditions, such as abstaining from alcohol or staying within a certain jurisdiction.
If you were charged with impaired driving, your licence will likely already be suspended for 90 days under Ontario’s Administrative Driver’s Licence Suspension (ADLS) program. Additional driving restrictions or suspensions may apply if you're convicted later.
Some individuals may also be required to install an ignition interlock device in their vehicle as a condition of licence reinstatement. Failing to follow these restrictions can result in additional charges.
Dealing with a DUI charge isn’t just about what happens in court—it affects your driving, your finances, and your future. The legal process can take weeks or even months, and the outcome can have long-term consequences. That's why hiring an experienced criminal defence lawyer early on is one of the best steps you can take.
Why Legal Representation Matters
Facing DUI charges in Ontario can undoubtedly be an overwhelming experience. The law around impaired driving is detailed and tricky. Without the right knowledge, it’s easy to get lost in the process. That’s why understanding why legal help is important can make a big difference.
DUI Law Is Technically Complex
DUI laws in Ontario are not simple. They involve criminal law rules, your constitutional rights, and how police must handle tests and arrests. Knowing all these details is crucial because mistakes or misunderstandings can hurt your defence. This is why navigating DUI charges requires more than just common sense—it requires experience with the legal system.
Consequences Are Too Serious to Handle Alone
The results of a DUI conviction are serious and long-lasting. Potential outcomes include acquiring a criminal record, losing your driver’s licence, or even spending time in jail. The court process has strict rules and deadlines. Any mistake made during your case might cause permanent damage, making it much harder to fight the charges later on.
Lawyers Understand How to Navigate the System
Legal professionals know how to spot problems in the Crown’s evidence. They can negotiate for lesser charges, like careless driving, when appropriate. They also help obtain important information from the prosecution, file legal requests, and prepare for court hearings. Protecting your Charter-protected rights is another key part of their role, including challenging any illegal actions by police.
Public Perception vs Legal Reality
One often faces harsh judgments and assumptions of guilt upon being charged with a DUI. This perception can add extra stress and stigma. However, being charged does not mean you are automatically guilty. Legal representation serves as a protective barrier against these misconceptions, ensuring your voice is heard and your rights are upheld throughout the legal process.
Ultimately, confronting DUI charges in Ontario requires legal guidance to navigate the complexities and serious consequences involved. Having the right support can help ensure your rights are protected and that you’re prepared for what comes next.
Final Thoughts
A DUI charge in Ontario is more than just a traffic ticket. It is a criminal offence that can impact your licence, your job, and your future. Even a single mistake behind the wheel can lead to legal and personal problems. That’s why it helps to know about the different types of impaired driving charges and what they mean. The more you understand, the better prepared you’ll be.
From driving with too much alcohol in your system to saying no to a breath test, the law is strict about impaired driving. And it’s not just about alcohol anymore. More people are being charged for driving after using drugs or a mix of drugs and alcohol, and the penalties are just as severe. Ontario has its own rules on top of the federal laws, which only adds to the confusion.
If you’ve been charged, you’re not alone. Remember, the steps you take next are important. Don’t wait around hoping it’ll go away. Get informed, stay organized, and talk to a lawyer as soon as you can. The right legal advice can make a real difference in your case.

Frequently Asked Questions
If you’re dealing with DUI charges in Ontario, you probably have a lot of questions. This can be a confusing and stressful time. To help, we’ve put together answers to some of the most common questions people ask about DUI charges.
What rights do I have during a DUI stop?
During a DUI stop in Ontario, you have the right to remain silent and not say anything that might incriminate you. You have the right to ask why you're being stopped, and you can request to speak to a lawyer. Police must inform you of your right to counsel and provide a reasonable opportunity to contact legal aid or private counsel under Section 10(b) of the Charter.
What is the difference between a DUI charge and a conviction?
A DUI charge is the formal allegation that you’ve committed an offence related to impaired driving by alcohol, drugs, or both. Being charged does not mean you are guilty—it marks the beginning of the legal process. A DUI conviction means that a court has found you guilty—either through a trial or guilty plea—and it leads to criminal penalties such as fines, licence suspensions, and possibly imprisonment.
Can I be charged with DUI even if my blood alcohol level is below the legal limit?
Yes, you can be charged with impaired driving even if your blood alcohol level is below the legal limit of 0.08. This can happen if the police reasonably believe your ability to operate a vehicle is impaired by alcohol or drugs, regardless of your actual BAC.
What are the immediate penalties for a first-time DUI offence in Ontario?
For a first-time impaired driving offence, the immediate penalties under the Administrative Driver’s Licence Suspension (ADLS) include a 90-day licence suspension and a 7-day vehicle impoundment, plus fees. Upon criminal conviction, penalties may include a minimum 1-year licence suspension, a minimum fine of $1,000, mandatory education or treatment programs, and an ignition interlock device for at least 1 year.
How long does a DUI case typically take to resolve in Ontario?
The duration of a DUI case in Ontario can vary widely based on its complexity and the court’s schedule. Typically, a DUI case can take anywhere from several months to over a year to fully resolve. Factors such as whether the case goes to trial or is resolved through a plea deal can impact the timeline.
What should I expect from the help of a DUI lawyer?
A DUI lawyer in Ontario will guide you through the legal process, review your case details, and explore potential defences. They will handle communications with the Crown and court, explain the consequences, and work to seek a favourable outcome—whether that means negotiating a reduced charge or preparing for trial.
