• Your driver’s licence has been suspended: Police usually impose an immediate 90-day administrative licence suspension after a DUI charge.
• Your vehicle was impounded: Your vehicle is typically impounded for 7 days, and you are responsible for towing and storage costs.
• You have a court date: Your first appearance will take place at the Oshawa courthouse, where your case begins in the Ontario Court of Justice.

This is the beginning of the legal process, not the final outcome.

A DUI Charge Is an Allegation, Not a Conviction

At Charitsis Law, our Oshawa DUI lawyers have defended hundreds of drivers charged with drinking and driving offences. We want you to understand right from beginning, that you have been accused, not convicted.

DUI charges are allegations, and these cases can be challenged based on the evidence and how the investigation was conducted.

The outcome of an impaired driving case often depends on many key factors, including:

• Roadside testing: how the stop was made and whether proper procedures were followed
• Breath sample procedures: whether testing was conducted accurately and in compliance with legal requirements
• Police observations: what the officer claims to have seen and how that evidence is presented
• Legal arguments & defence strategies: identifying Charter issues, challenging how evidence was obtained, and raising legal issues that can lead to charges being withdrawn, dismissed, or defeated at trial

Issues with any part of the evidence can affect the strength of the case, leading to a dismissal. At Charitsis Law, DUI charges have been successfully resolved with cases withdrawn, dismissed, or defeated at trial.

Types of DUI Charges in Oshawa

In Oshawa and throughout Durham Region, several different criminal charges can arise from an impaired driving investigation. While people often refer to these matters generally as “DUI,” the Criminal Code of Canada contains several specific offences that may apply depending on the circumstances of the investigation.

Common DUI-related charges heard at the Ontario Court of Justice in Oshawa include:

• Impaired Driving: This charge applies where the prosecution alleges that alcohol or drugs impaired the driver’s ability to operate a motor vehicle.
• Over 80 (Blood Alcohol Over the Legal Limit): This charge is based on breath testing results showing that the driver’s blood alcohol concentration exceeded the legal limit.
• Care and Control While Impaired: A person can be charged even if the vehicle was not moving. Being in care or control of a vehicle while impaired may still lead to a criminal charge.
• Refusing or Failing to Provide a Breath Sample: Refusing a lawful roadside or station breath demand can result in a criminal charge with penalties similar to an impaired driving conviction.

DUI and impaired driving charges require strict evidence from the police that must be proven in court.

What Are the Penalties for DUI in Oshawa?

Where a driver is convicted of impaired driving, the penalties for DUI charges are mandatory under the Criminal Code of Canada. Once guilt has been established, the judge has very limited discretion in determining the sentence.

For a first offence, you face:

• Criminal Record: A conviction results in a permanent criminal record. This can affect employment, professional licensing, immigration matters, and travel to the United States.
• Minimum 1-Year Driving Prohibition: The court will impose at least a one-year licence suspension. You cannot legally drive during this period.
• Fine Based on Breath Reading: The minimum fine is $1,000. If your blood alcohol reading was significantly higher, the minimum fine increases. Court costs and victim surcharges are added.
• $550 Administrative Penalty: This provincial penalty applies in addition to court-imposed fines.
• Mandatory 8-Hour Education Course: Completion of an approved education program is required before your licence can be reinstated.
• Ignition Interlock Requirement: You must install and use an ignition interlock device for at least one year. All installation and monitoring costs are paid by you.
• Medical Evaluation: Drivers are required to complete a medical or substance use assessment before their licence can be reinstated. This may involve being assessed for alcohol or drug addiction and completing additional steps before you are allowed to drive again.
• Insurance Consequences: Insurance premiums often increase significantly following a conviction.
• Possible Jail in Serious Cases: Jail is not mandatory for a first offence, but it is legally available in more serious situations.

These penalties apply automatically. The judge cannot simply waive or even reduce them.

Before accepting a criminal record and a one-year driving ban, call and speak with a criminal defence lawyer to review your case, assess the evidence, and determine whether the charge can be challenged.

What a DUI Charge Means for You

You have been charged with a DUI or drinking and driving offence. The next decision is yours. Can accept the penalties that come with a conviction, or should you consider disputing the charge?

If You Accept the Charge and Plead Guilty

• Criminal Record: A conviction results in a permanent criminal record. This can affect employment, professional licences, travel to the United States is prohibited, and long-term opportunities.
• Driving Prohibition: You are legally prohibited from driving for at least one year. If you drive while suspended, you risk additional criminal charges, including jail.
• Financial Consequences: Fines start at $1,000 for a first offence. However, the total cost is often much higher. Many drivers are moved to high-risk insurance, which can range from approximately $5,000 to $10,000 per year for several years. In addition, you must pay licence reinstatement fees, ignition interlock costs, and mandatory program expenses.
• Ignition Interlock Requirement: convicted drivers must install an ignition interlock device at their own expense for at least one year.

When all costs are considered, a DUI conviction can result in tens of thousands of dollars in financial impact over time. Most drivers cannot afford to just go in and plead guilty.

The Decision You Face for DUI Charges in Oshawa

After a DUI charge, you face an important decision. You can accept a conviction and the long-term consequences that come with it, or you can speak with one of our Oshawa DUI lawyers to review your case and identify issues that may lead to the charge being withdrawn or reduced before deciding how to proceed.

Option 1: Plead Guilty to a DUI Charge

Pleading guilty brings certainty. It also brings permanent consequences.

A conviction results in a permanent criminal record for life, a driving prohibition, financial penalties, mandatory programs, ignition interlock requirements, and significant insurance increases. Once guilt is entered, those consequences cannot be undone.

For some people, pleading guilty feels like the fastest way to move forward. The risk is that the decision is made without fully understanding whether the charge could have been challenged or resolved differently.

Option 2: Review the Evidence Before You Decide

Can a DUI charge be dropped or reduced?

In many Oshawa DUI cases, there are legal issues and defences worth examining, and even the Durham Regional Police will tell you they don’t win every case. Some cases are more defensible than people first believe.

The only way to know where you stand, is to review the disclosure with a lawyer experienced in DUI defence.

• The Crown must prove the case: A charge is an allegation, not a conviction. The prosecution must establish every element beyond a reasonable doubt, without infringing upon your legal rights in the process.
• Legal standards are strict: Traffic stops, breath demands, and testing procedures must follow precise legal requirements. When they don’t, it can affect the strength of the case.
• Outcomes can vary: Some charges are withdrawn. Some proceed to trial and are successfully defended. In other situations, matters may be resolved in a way that avoids the serious long-term consequences, including a permanent criminal record.

Before making a decision that could affect you for many years, it makes sense to understand whether your case has weaknesses that can be used in your defence.

As Oshawa DUI Lawyers we know that many DUI cases can be more defensible than what they first appear.

A DUI Charge Does Not Automatically Mean a Conviction

When defending DUI charges, important issues are not always obvious at first. In many cases, the outcome often depends on how the investigation unfolded and whether there are problems with the evidence that can be challenged.

• Procedural errors: mistakes in how the investigation was carried out
• Technical issues: problems with breath testing or timing requirements
• Weaknesses in the evidence: gaps or inconsistencies in the Crown’s case
• Police actions: whether the officer followed proper legal steps

These issues are often only identified through a careful review of the disclosure. Our Oshawa DUI lawyers at Charitsis Law will review the evidence with you, explain your options clearly, and help you decide how to move forward.

The DUI Court Process | Oshawa Criminal Courts

Impaired driving charges in Oshawa are heard at the Ontario Court of Justice at 150 Bond St. E. in Oshawa. The court process follows a series of steps. We explain each stage so you understand what to expect and how your case moves forward.

First Court Appearance

At the first appearance, no trial takes place. The Crown Attorney may ask whether you have retained a lawyer. The court will encourage you to get legal advice before making any decisions, your case will be remanded, meaning scheduled for another court date several weeks so you can do so.

Where you’ve arranged for a criminal lawyer, the Crown may request a written confirmation or a letter from the lawyer, advising the court that the lawyer is representing you.

The purpose of this appearance is administrative — it sets the stage for the next steps.

Disclosure Review

At the first court appearance, the Crown attorney will usually provide the disclosure relating to your DUI charge. Disclosure is the evidence the Crown relies on to prove the case against you.

This material typically includes police notes, breath testing records, witness statements, and other documents or evidence the prosecution intends to rely upon in court.

You should review the disclosure carefully to see whether it matches your recollection of what happened and whether there are any discrepancies you notice. However, identifying potential legal issues usually requires the review and analysis of a lawyer experienced in DUI defence.

As DUI lawyers we know what to look for, the issues and errors that can we used to build your defence. This stage often determines how the case will proceed.

Pre-Trial Meeting With the Crown

After disclosure is reviewed, as your defence we’ll schedule a pre-trial hearing with the crown attorney.

This is a meeting between the crown and our defence lawyers. The meeting involves identifying legal issues, consider weaknesses or issues in the evidence, or exploring whether the charge could be withdrawn or resolved other than going to trial.

In some situations, charges may be withdrawn. In others, discussions may focus on resolving the matter in a way that avoids the most serious long-term consequences, like reducing the charge to a traffic ticket like careless driving thereby avoiding a criminal record.

Trials for DUI Charges

Where your charge proceeds to trial, the Crown must prove the charge beyond a reasonable doubt.

Reasonable doubt means the judge must be firmly convinced, based on the evidence, that you committed the offence. If there is a real and logical doubt arising from the evidence or the way it was obtained, the court must find you not guilty.

Police officers and any other witnesses must attend court to give evidence. They are subject to cross-examination. The breath testing procedures and all surrounding circumstances are examined in detail.

A trial is where legal arguments and evidentiary issues are tested fully before the court.

Breathalyzer Evidence in Oshawa DUI Cases

In many DUI cases, breath testing evidence plays an important role in determining whether the prosecution can prove a charge. When a driver is arrested for impaired driving in Oshawa, police will usually require breath samples to be taken at the station using an approved breath testing instrument.

• Impaired Driving – is based upon the physical observations and your driving
• Drive over 80 mgs – is based upon being over the legal limit for having alcohol in the body

Breathalyzer devices measure alcohol concentration, described as a BAC (Blood Alcohol Concentration). However, the results are only reliable if the testing process is carried out properly. This includes how the samples are taken, whether the required steps are followed, and whether the timing of the tests meets legal requirements.

If the testing process is not carried out properly, it can affect whether the results can be relied on in court.

Issues With Breathalyzer Evidence

Several factors can affect the reliability and admissibility of breath testing evidence:

• Proper grounds for the breath demand: Police must have a valid legal basis to require a breath sample
• Timing of the breath tests: Samples must be taken within required time limits
• Operation of the instrument: The device must be properly maintained and used by a qualified officer
• Accuracy of records: Maintenance logs, calibration checks, and testing procedures may become important evidence
