Ontario DUI Lawyers
Last Updated: October 9, 2024
In Ontario, Driving Under the Influence (DUI) is a serious criminal offence that occurs when an individual operates a motor vehicle while their ability is impaired by alcohol or drugs. The legal blood alcohol concentration (BAC) limit in Ontario is 0.08%, meaning that if a driver’s BAC is found to be at or above this level, they can be charged with a DUI. However, drivers with a BAC between 0.05% and 0.08% may also face penalties under the province’s “warn range” sanctions.
The consequences of a DUI conviction in Ontario are severe and can include hefty fines, jail time, license suspension, and mandatory participation in education or rehabilitation programs. Penalties increase for repeat offenders and those with high BAC levels. A DUI conviction can also lead to long-term consequences, such as higher insurance premiums, employment difficulties, and travel restrictions.
Given the complexity of DUI laws and the potential for life-altering consequences, it is crucial for anyone facing DUI charges in Ontario to seek the guidance of an experienced DUI lawyer. A skilled legal professional can help protect your rights, navigate the legal system, and build a strong defence to minimize the impact of a DUI charge on your life. Don’t face DUI charges alone – contact a reputable DUI lawyer today to discuss your case and explore your options.
Role of DUI Lawyers in Ontario
DUI lawyers play a crucial role in protecting the rights of individuals facing charges related to Ontario DUI laws. These legal professionals specialize in the complex area of DUI law, possessing a deep understanding of the provincial legislation, legal precedents, and courtroom procedures involved.
When taking on a DUI case, a lawyer will carefully assess the circumstances surrounding the arrest and evaluate the evidence against their client. This may involve scrutinizing police reports, witness statements, and video footage to identify any potential weaknesses or inconsistencies in the prosecution’s case.
One key aspect of a DUI lawyer’s role is challenging the evidence presented by the Crown. This may include disputing the accuracy or admissibility of breathalyzer tests, questioning the validity of field sobriety tests, or highlighting any procedural errors made by law enforcement during the arrest. By successfully challenging this evidence, a DUI lawyer can work towards having the charges reduced or dismissed.
In some cases, a DUI lawyer may negotiate with the prosecution to secure reduced penalties for their client through plea bargaining. This can result in lesser charges, shorter license suspensions, or the dismissal of certain penalties altogether.
If the case proceeds to trial, a DUI lawyer will be instrumental in preparing a strong defence strategy and advocating on behalf of their client in court. This includes cross-examining witnesses, presenting evidence, and arguing for the most favourable outcome possible.
Throughout the legal process, a DUI lawyer serves as a knowledgeable guide and fierce advocate, working tirelessly to protect their client’s rights and minimize the impact of a DUI charge on their life.

Common Defenses Used by DUI Lawyers
DUI lawyers in Ontario employ various defense strategies to challenge the charges against their clients and protect their rights. One common defense is to argue that the initial traffic stop was improper, claiming that the police officer lacked reasonable suspicion to pull over the driver. If successful, this argument can lead to the exclusion of evidence obtained during the stop.
Another frequently used defence is to challenge the accuracy of breathalyzer tests. DUI lawyers may question the calibration, maintenance, or administration of the device, as well as the qualifications of the officer operating it. If the reliability of the breathalyzer results can be cast into doubt, the prosecution’s case may be significantly weakened.
Ontario DUI Penalties and Their Impact
Ontario impaired driving charges can be severe, even for first-time offenders. Those convicted of a first DUI offence face a minimum fine of $1,000, a license suspension of at least one year, and the possibility of jail time of up to six months. Additionally, they may be required to participate in education or rehabilitation programs and install an ignition interlock device in their vehicle.
Repeat offenders face even harsher consequences. A second DUI conviction carries a minimum 30-day jail sentence, a license suspension of at least three years, and a mandatory ignition interlock device for at least six months. Penalties continue to escalate for subsequent offences, with longer jail terms, lengthier license suspensions, and steeper fines.
A DUI conviction can have a profound impact on an individual’s driving privileges and insurance premiums. In addition to the mandatory license suspension, convicted drivers may need to complete a remedial education program and pay a reinstatement fee to regain their license. Insurance premiums can skyrocket following a DUI conviction, as insurers consider these drivers high-risk.
Moreover, a DUI conviction results in a criminal record, which can have long-lasting effects on an individual’s personal and professional life. This can lead to difficulties in securing employment, housing, and travel opportunities. A criminal record can also affect child custody arrangements and other legal matters.
Legal Process for DUI Charges in Ontario
When an individual is arrested for a DUI in Ontario, they will be taken into custody and required to provide breath samples to determine their blood alcohol concentration (BAC). If the BAC is over the legal limit or the officer has reason to believe the individual is impaired, they will be formally charged with a DUI offence.
After the arrest, the accused will be released on a promise to appear in court or may need to attend a bail hearing, depending on the circumstances of the case and their criminal history.
In the pre-trial phase, the accused’s lawyer will review the evidence provided by the prosecution and may engage in negotiations for a plea deal. If no agreement is reached, the lawyer may file pre-trial motions to challenge the admissibility of certain evidence or argue for the dismissal of charges based on insufficient evidence or Charter rights violations.
If the case proceeds to trial, the prosecution will present evidence against the accused, including testimony from the arresting officer and any witnesses. The defence lawyer will cross-examine witnesses and present evidence in support of the accused.
If found guilty, the accused will face sentencing, which may include fines, jail time, license suspension, and mandatory participation in education or rehabilitation programs, as outlined in the Canadian Criminal Code and Ontario’s Highway Traffic Act. The severity of the sentence will depend on factors such as the accused’s BAC level, prior DUI convictions, and any aggravating circumstances.
In some cases, DUI lawyers may argue that their client’s high BAC reading was due to a medical condition, such as acid reflux or gastroesophageal reflux disease (GERD). These conditions can cause alcohol to be released from the stomach into the mouth, leading to falsely elevated BAC levels.
Additionally, DUI lawyers may contend that their client’s rights were violated during the arrest or testing procedures. This could include issues such as the failure to provide access to legal counsel, improper administration of field sobriety tests, or the use of excessive force during the arrest.
By employing these and other defence strategies, DUI lawyers work to protect their client’s rights, challenge the evidence against them, and secure the most favourable outcome possible when facing DUI penalties in Ontario.

How much does a DUI lawyer cost in Ontario?
DUI lawyer fees can vary significantly depending on several factors, such as the lawyer’s experience, the complexity of your case, and the amount of time required to resolve your matter. While DUI lawyer fees may seem substantial, it is essential to consider the potential long-term financial and personal consequences of a DUI conviction, such as increased insurance premiums, fines, and the impact on your employment and travel opportunities. Investing in a skilled DUI lawyer can help you minimize these consequences and protect your rights throughout the legal process.
Can a DUI be expunged from my record?
In Canada, including Ontario, a DUI conviction cannot be completely expunged or removed from your criminal record. However, you may be eligible to apply for a record suspension (formerly known as a pardon) after completing your sentence and waiting a specified period.
For a first-time DUI offence, you must wait five years from the date you complete your sentence before applying for a record suspension. For subsequent DUI offences, the waiting period is ten years. During this waiting period, you must demonstrate good conduct and not commit any further criminal offences.
It is important to note that a record suspension does not erase your criminal record; instead, it sets your conviction aside and allows you to access more opportunities, such as employment and travel. However, your DUI conviction may still be disclosed in certain circumstances, such as when applying for jobs that require a vulnerable sector check.
What should I do immediately after being charged with a DUI?
If you have been charged with a DUI in Ontario, it is crucial to take immediate action to protect your rights and minimize the potential consequences of your charges. The first step you should take is to contact an experienced DUI lawyer as soon as possible.

It is also crucial to refrain from discussing your case with anyone other than your lawyer, as any statements you make could potentially be used against you in court. Avoid posting about your charges on social media or contacting any witnesses directly.
