Impaired Driving (DUI) Charges
Impaired driving, often called DUI, is one of the most common criminal charges in Ontario. A person can be charged if police believe their ability to drive was impaired by alcohol, drugs, or a combination of both.
You can also face an impaired driving charge if you are accused of driving with a blood alcohol concentration over the legal limit, refusing to provide a breath sample, or being in care and control of a vehicle while impaired.
A conviction can result in a criminal record, a driving prohibition, significant fines, higher insurance costs, and, in some cases, jail.
At Charitsis Law, we carefully examine every aspect of the Crown’s case, including the traffic stop, roadside investigation, breath testing procedures, and whether the evidence meets the legal standard required for a conviction.

Penalties for DUI & Impaired Driving Charges
What Happens If You Are Convicted?
As DUI lawyers in Toronto, we believe every DUI charge deserves a careful defence. You don’t know what legal or evidentiary issues may arise during the court process or trial until an experienced criminal lawyer reviews your case.
These penalties apply only if you are convicted.
- Driver’s licence suspension: Most drivers lose their licence immediately after being charged. If you are convicted, the court will impose a driving prohibition, and additional Ministry of Transportation suspensions and licence reinstatement requirements may also apply.
- Criminal record: A DUI conviction results in a criminal record that can affect employment opportunities, professional licences, volunteer positions, immigration matters, and international travel.
Learn how a criminal record can affect your future. - Fines and possible jail: A first offence carries a mandatory minimum fine of $1,000. Higher minimum fines apply where breath alcohol readings are significantly over the legal limit. Repeat offences and more serious cases can also result in a jail sentence.
- Higher insurance costs: Insurance premiums often increase significantly following a DUI conviction. Many drivers are required to obtain high-risk insurance, which can cost thousands of dollars more each year.
- Ignition interlock and licence reinstatement: Before driving privileges are fully restored, many drivers must install an ignition interlock device, complete mandatory education or treatment programs, and pay significant installation, monitoring, and licence reinstatement fees.
- Employment and travel consequences: A criminal conviction may affect careers that require driving, professional licences, security clearances, and travel to countries such as the United States.
- The true cost of a DUI conviction: Court fines are often only the beginning. Once increased insurance premiums, ignition interlock costs, licence reinstatement fees, mandatory programs, and other expenses are added together, the total financial impact can easily reach tens of thousands of dollars.

Defending DUI Charges in Toronto
Legal issues in DUI charges that shape your defence.
Every DUI defence in Toronto begins with a careful review of the Crown’s disclosure and your version of what happened. We then identify the defences and legal arguments to determine whether the Crown can prove the charge or whether there is a resolution or reduced charge, or will the case go to trial.
When building a defence strategy for a DUI charge, we look for:
- Weaknesses in the Crown’s evidence
- Charter of Rights violations
- Legal issues with the traffic stop or arrest
- Errors in the breath-testing procedure
- Inconsistencies in police notes, witness statements, and other evidence
- Gaps in the timeline of events or unreasonable delays
- Problems with how evidence was collected, handled, or documented
- Relevant court decisions and legal precedents that may strengthen your defence
No two DUI cases are exactly alike. Sometimes the strongest defence is a Charter challenge. In other cases, it may involve challenging the breath-testing procedure, the reliability of the evidence, or whether the police followed the legal requirements during the investigation.
“I wish to express my deepest gratitude to Nicholas Charitsis for his support throughout this entire process. Thanks to his expertise and encouragement, the judge ruled in my favour. His availability and guidance were invaluable. A huge thank you for everything you’ve done for me!”
— John D., Google Review
To obtain a conviction, the Crown Attorney must prove the impaired driving with evidence gathered according to the law. This includes the police investigation, the traffic stop, the breathalyzer-testing procedures, and whether your Charter of Rights were respected. When problems are found, they can create strong legal defences for DUI charges.

DUI Penalties In Toronto
What’s at Risk If You’re Convicted of a DUI in Toronto?
The penalties for a DUI have serious consequences. The penalties for DUI affect your licence, finances, employment, and ability to travel. Persons with immigration applications may be seriously at risk.
- Possible Jail Sentence – While jail is not mandatory for a first impaired driving conviction in Toronto, it remains a possibility in more serious cases, particularly where are high alcohol readings, accidents, injuries, or other aggravating factors.
- Criminal Record – A DUI conviction results in a criminal record for life. A criminal records affect employment opportunities, professional licences, volunteer positions, immigration matters, and international travel.
- Driving Prohibition – Upon conviction of any DUI charge, the Toronto courts will impose a mandatory driving prohibition that prevents you from driving anywhere in Canada. The prohibition is at least one year and may be longer depending on the circumstances and any prior convictions.
- Medical Assessments & Programs – Before a licence can be reinstated, drivers may be required to complete education programs, treatment programs, medical assessments, or other Ministry-approved requirements. These additional steps can create significant delays and costs.
- Ignition Interlock Requirements – Many drivers must participate in Ontario’s Ignition Interlock Program before regaining full driving privileges. This requires a breath-testing device to be installed in the vehicle at the driver’s expense, along with ongoing monitoring and maintenance fees.
- Increased Insurance Costs – A DUI conviction often results in substantially higher insurance premiums. Many drivers are put into high-risk insurance for several years, and insurance costs may double or even triple.
- Travel Restrictions – A criminal record can create difficulties travelling to other countries, including the United States. Many people convicted of impaired driving are denied entry into the USA.
- Employment & Professional Consequences – Certain employers, professional regulators, and licensing bodies may require disclosure of a criminal conviction. This can be particularly important for professionals, commercial drivers, and individuals working in positions of trust.
The full impact of a DUI conviction is one of the reasons it is important to obtain legal advice before deciding whether to plead guilty.
Many of the clients represented by Charitsis Law have had their case go to trial, whereupon the judge found them not guilty of the offence.

Breathalyzer Evidence & DUI Defence
Can Breathalyzer Results Be Wrong?
Having reviewed hundreds of DUI charges, we know that sometimes police officers and breathalyzer technicians can make mistakes. The police must follow strict legal procedures when investigating impaired driving, administering breath tests, and collecting evidence.
As an example, when investigating DUI charges, the police officers are timed. There are times that are important for breathalyzer test results that must be done properly, such as:
- time of offence
- time of arrest
- time of the breathalyzer demand
- time taken to get to the police station
- time between arriving and placed before the breathalyzer technician
- time between the two breathalyzer tests
If any of these times are wrong or inconsistent, it can can dramatically affect the outcome of your charges.
The key issue is whether the Crown Attorney can prove the driver’s blood alcohol level was over the legal limit within two hours of driving. If the first breath sample is taken later than two hours, the Criminal Code applies a special calculation rule. As a result, the timing of the breath demand, arrest, and testing can become important evidence in a DUI defence.
Legal Rights & Charter Violations
Were Your Charter of Rights Violated?
When legal rights have been violated it can affect your case. Every person charged with a criminal offence has rights protected by the Canadian Charter of Rights and Freedoms, and the police must respect those rights throughout the investigation.
Charter of Rights violations can include such things as:
- Was the traffic stop was lawful.
- Did police had legal grounds to demand a breath sample.
- Were you advised of your right to speak with a lawyer without delay.
- Were you were given a private opportunity to speak with a lawyer.
- Are there were unreasonable delays before breath testing.
- Did police followed the proper breath-testing procedures.
- Were your Charter rights were otherwise violated during the investigation.
When Charter rights have been violated, it can create important legal defences that may not be obvious to someone unfamiliar with the criminal justice system. In many cases, those Charter of Rights violations result in charges being reduced, withdrawn, or dismissed altogether.
The DUI Court Process In Toronto
What to expect after being charged with DUI.
Most impaired driving charges in Toronto are heard at the Ontario Court of Justice at 10 Armoury Street. While every case is different, most impaired driving charges follow a similar court process.
First Court Appearance
Your first court appearance is not a trial. The purpose of this court date is to receive disclosure, advise the court whether you have spoken with a lawyer, and schedule the next steps in your case.
Disclosure Review
Disclosure is the evidence the Crown Attorney intends to rely upon in court to convict you. It often includes police notes, witness statements, breath testing records, and other documents relating to the investigation.
Many people leave court with disclosure but are unsure what it means or what they should do next. This is often the stage where people first learn whether there are legal defences available and how strong the Crown Attorney’s case really is.
If you have received disclosure from the Crown Attorney, call and speak with Nicholas Charitsis. The only way to understand the legal defences that may be available to you is to have the evidence carefully reviewed by an experienced DUI lawyer.
After reviewing the evidence and hearing your side of the story, Mr. Charitsis can explain the legal defences he sees, discuss the strengths and weaknesses of the case against you, and explain how he would approach defending your DUI charge.
Before making any decisions about your case, it is important to understand the evidence, the legal issues involved, and the options available to you.
Pre-Trial Discussions
After the disclosure has been reviewed and you decide to retain Charitsis Law, we will arrange a pre-trial discussion with the prosecutor. During that meeting, we will raise any legal issues we’ve have identified, challenge weaknesses in the evidence, and discuss any concerns looking to have the charge dropped.
These discussions may involve legal defences, Charter violations, witness credibility issues, disclosure concerns, or other problems that affect the crowns’s ability to prove the charge.
In some pre-trials, charges can be withdrawn, reduced, or resolved without proceeding to trial. The approach taken will depend on the evidence, the legal issues involved, and the strengths of our team.
Defending DUI Charges at Trial
How our Toronto DUI lawyers defend your case at trial.
Cross-Examining Police Officers and Witnesses
If your DUI charge proceeds to trial, our Toronto DUI lawyers challenge the Crown Attorney’s evidence and advance every available legal defence. Police officers, breath technicians, and other witnesses must testify in court and are subject to cross-examination.
During cross-examination, we may challenge:
- Inconsistencies in the officer’s evidence
- Conflicts between police notes and testimony
- The reliability of witness evidence
- Observations made during the investigation
- The accuracy of the police investigation
Reviewing Breath-Testing Records and Evidence
Breathalyzer evidence is often central to a DUI prosecution. We carefully review the Crown’s disclosure to determine whether the legal requirements were followed and whether the evidence is reliable.
This may include reviewing:
- Police notes
- Approved Instrument printouts
- Breath test results
- Breath technician records
- Witness statements
- Video evidence
- Other Crown disclosure
Raising Charter and Legal Arguments
Some DUI cases are defended by challenging the lawfulness of the police investigation or relying on previous court decisions.
These legal arguments may involve:
- Charter of Rights violations
- Unlawful detention or arrest
- Right to counsel issues
- Problems with the breath demand
- Relevant Ontario case law and legal precedents
The Crown Must Prove the Charge
Proving the charge to the judge always rests with the Crown Attorney. Before a judge can convict you, every part of the offence must be proven legally and beyond any doubt.
To obtain a conviction, the Crown must prove:
- The police investigation was lawful
- The breath-testing procedures complied with the law
- The evidence presented at trial is reliable
- Your Charter rights were respected
- The evidence proves the charge beyond any doubt
If the Crown cannot prove the charge legally, the court cannot convict you.
Every DUI trial is different. The defence strategy depends on the evidence, the applicable law, and the specific facts of your case. Our goal is to identify every available defence, challenge the Crown’s case, and present the strongest legal arguments on your behalf.
