What Happens After a DUI (Impaired Driving) Charge in Toronto?

The night felt ordinary until it wasn’t.

Maybe it was a RIDE program checkpoint you did not see coming. Maybe a minor collision brought police to the scene. Maybe you thought you were fine to drive and the breathalyzer told a different story. Maybe the situation was more complicated than any of those — a prescription medication, a long gap between your last drink and when you got behind the wheel, a device that gave a reading you do not understand.

However it happened, you are now on the other side of it. You have been charged with impaired driving in Toronto. And you are likely experiencing something that every person in this situation experiences in those first hours: a combination of shock, fear, confusion, and a desperate need to understand what happens next.

This guide exists to answer that question — honestly, specifically, and in plain language. Because understanding the DUI process in Ontario is not just useful. It is the foundation of every decision you are about to make. And those decisions matter more than most people realize in the hours immediately after a charge is laid.

What a DUI Charge Actually Means in Canada

First, it is important to understand what you are actually facing — because the term “DUI” is commonly used but not a precise legal term under Canadian law.

In Canada, impaired driving offences are governed by Part VIII.1 of the Criminal Code of Canada. There are three distinct criminal offences that most people refer to collectively as “DUI”:

Operation While Impaired — Section 320.14(1)(a): Operating or having care or control of a motor vehicle while your ability to do so is impaired by alcohol, a drug, or a combination of both. The Crown does not need a specific blood alcohol reading to prove this offence — only that impairment existed to any degree.

Operation With Blood Alcohol Concentration at or Above .08 — Section 320.14(1)(b): Operating or having care or control of a vehicle with a blood alcohol concentration of 80 milligrams or more of alcohol per 100 millilitres of blood. This is a separate offence from impairment — you can be charged with both simultaneously.

Failure or Refusal to Provide a Breath Sample: If you refused or failed to provide a breath sample when lawfully demanded by a police officer, this is itself a criminal offence carrying the same penalties as a DUI conviction.

Understanding which specific charge — or combination of charges — has been laid against you is one of the first and most important things your lawyer will establish. Because the specific charge shapes the defence strategy that gives you the best possible outcome.

The First Hours After a DUI Charge — What You Need to Know Right Now

The period immediately following a DUI charge is the most consequential of the entire process. Here is what is happening and what you should — and should not — do.

Your Licence Is Already Suspended

You need to know this immediately: in Ontario, an immediate roadside licence suspension takes effect the moment you are charged with impaired driving under the Highway Traffic Act. For a first charge, that suspension is 90 days and it begins at the scene — before any court appearance, before any finding of guilt, before any judge has reviewed a single piece of evidence.

This administrative suspension operates entirely separately from any criminal penalty. It is automatic and it is immediate. You cannot drive while this suspension is in effect.

Your Vehicle May Be Impounded

Alongside the licence suspension, your vehicle will typically be impounded for 7 days on a first impaired driving charge in Ontario. The costs of towing and storage are your responsibility.

You Were Released — But With Conditions

Most first-offence DUI charges in Toronto result in release from custody — either at the scene or after a period at the station — with conditions attached. Those conditions typically prohibit you from operating a motor vehicle and may include other requirements. Violating any condition of your release is a separate criminal offence that makes your situation significantly worse. Review your release documents carefully and comply with every condition precisely.

The Most Important Thing You Can Do Right Now

Call an experienced DUI lawyer in Toronto before you do anything else. Before you discuss the case with friends. Before you post anything online. Before you make any statements to anyone about what happened.

At Costa Law Firm, we are available 24 hours a day, seven days a week for clients facing urgent criminal charges. A DUI charge is exactly that kind of situation — and the advice you receive in that first conversation shapes every decision that follows.

The DUI Court Process in Toronto — Stage by Stage

Once the immediate aftermath is managed, your case enters the Ontario court system. Here is exactly how that process unfolds.

Stage 1 — First Court Appearance

Your first court date is a procedural appearance — not a trial, not a hearing on the evidence, and not a moment where any final decisions are made. At this appearance, you indicate whether you have retained legal counsel and request time to receive and review the Crown’s disclosure. If you have already retained Costa Law Firm, we appear on your behalf and begin the process of obtaining your disclosure materials.

This first date is important not for what happens in the courtroom but for what starts outside of it — the disclosure review process that is the foundation of every effective DUI defence.

Stage 2 — Disclosure Review

Disclosure is the complete package of evidence the Crown intends to rely upon — and it is where a skilled DUI defence lawyer does their most critical work.

In a DUI case, disclosure typically includes:

• Police officer’s notes from the traffic stop and arrest
• The results of any Approved Screening Device test conducted at the roadside
• The Approved Instrument (breathalyzer) readings taken at the station
• The maintenance and calibration records for the specific instrument used
• The qualifications of the officer who administered the breath tests
• Any video footage from police dashcams or station cameras
• Blood sample analysis reports where blood testing was conducted
• The Certificate of Qualified Technician

Every one of these items is subject to scrutiny. Every procedural step that was required and was not correctly followed is a potential ground for challenge. The disclosure review is where your lawyer identifies the strengths and weaknesses in the Crown’s case — and builds the defence strategy that gives you the best possible outcome.

Stage 3 — Crown Negotiations

After reviewing disclosure, your lawyer assesses whether there are grounds for pre-trial resolution — negotiating with the Crown for a withdrawal, a reduction of charges, or a resolution that avoids the most serious consequences.

Not every DUI case goes to trial. Many are resolved through skilled negotiation — and the outcome of those negotiations depends almost entirely on the strength of the defence position your lawyer has built through disclosure review. A Crown who knows the defence has identified significant evidentiary problems in their case negotiates very differently from one who believes their case is airtight.

Stage 4 — Pre-Trial Applications

If the disclosure review reveals violations of your constitutional rights under the Canadian Charter of Rights and Freedoms — an unlawful traffic stop, a failure to properly advise you of your right to counsel, a breach of the procedures required before breath testing — your lawyer files pre-trial applications to exclude the affected evidence.

In DUI cases, this is where some of the most important legal battles are fought. A successful Charter application can result in the breathalyzer evidence being excluded entirely — and without that evidence, the Crown’s case frequently cannot survive.

Common Charter applications in Toronto DUI cases include:

Section 8 — Unlawful Search: If the traffic stop was conducted without legal authority, all evidence obtained as a result may be excluded.

Section 9 — Arbitrary Detention: If you were detained without legal justification, evidence obtained during that detention may be challenged.

Section 10(b) — Right to Counsel: If police failed to properly advise you of your right to speak to a lawyer without delay, or failed to give you a meaningful opportunity to do so before breath testing proceeded, the breath readings may be excluded.

These are not technicalities. They are constitutional protections that exist specifically to ensure government authorities operate within the law — and they are among the most powerful tools available in DUI defence.

Stage 5 — Trial

If the matter is not resolved through negotiation or pre-trial applications, it proceeds to trial. At trial, the Crown presents its evidence — through the testimony of the arresting officer, the breath technician, and any other witnesses — and your lawyer challenges that evidence through cross-examination, legal argument, and the presentation of defence evidence where appropriate.

DUI trials in Ontario are highly technical. They involve detailed analysis of breathalyzer evidence, officer credibility, procedural compliance, and the application of specific legal presumptions that the Crown relies upon to prove blood alcohol concentration at the time of driving.

At Costa Law Firm, our criminal defence lawyers have the experience, the technical knowledge, and the courtroom advocacy skills to present the strongest possible case at trial — and to hold the Crown to its burden of proving every element of the charge beyond a reasonable doubt.

DUI Penalties in Ontario — What You Are Facing

Understanding the full range of penalties for a DUI conviction in Ontario is not meant to frighten you — it is meant to help you understand exactly why this charge deserves to be taken seriously from the very first day.

Criminal Penalties

First Offence:

• Mandatory minimum fine of $1,000 plus a 30% victim fine surcharge
• Mandatory minimum one-year driving prohibition under the Criminal Code
• Mandatory participation in an alcohol treatment and education program
• Ignition interlock device required for a minimum of one year as a condition of licence reinstatement
• Permanent criminal record
• Possible imprisonment — though a custodial sentence for a straightforward first offence without aggravating circumstances is not common, it is at the court’s discretion

Second Offence:

• Mandatory minimum 30 days imprisonment
• Mandatory minimum two-year driving prohibition
• Extended ignition interlock requirement
• Victim fine surcharge

Third and Subsequent Offences:

• Mandatory minimum 120 days imprisonment
• Mandatory minimum three-year driving prohibition
• Extended ignition interlock requirements

Impaired Driving Causing Bodily Harm:

• Maximum 14 years imprisonment
• Mandatory prohibition from driving

Impaired Driving Causing Death:

• Maximum life imprisonment

Beyond the Criminal Penalties

The consequences of a DUI conviction extend far beyond what a judge imposes in the courtroom.

Insurance: A DUI conviction in Ontario results in dramatically increased insurance premiums — often 100% to 300% or more — for a minimum of three years following conviction. Many standard insurers will not offer coverage to a convicted impaired driver, requiring placement in the high-risk market at significantly elevated cost.

Criminal Record: A DUI conviction creates a permanent criminal record that appears on background checks for employment, professional licensing, and volunteer positions. Many regulated professions — including healthcare, law, teaching, financial services, and others — require disclosure of criminal convictions and may review or revoke licences upon conviction.

Travel to the United States: A DUI conviction makes you inadmissible to the United States under American immigration law. Crossing the border for business or personal travel requires a specific waiver — a time-consuming and uncertain process that imposes practical limitations for many years following conviction.

Licence Consequences: The Highway Traffic Act administrative licence suspension runs separately from the criminal driving prohibition and begins immediately at the time of charge. Ontario’s Back on Track program and ignition interlock requirements must be completed before licence reinstatement can be obtained.

How DUI Charges Are Defended — What Actually Works

DUI charges in Ontario are among the most successfully defended criminal charges in the system — when the defence is properly prepared and the right arguments are made at the right stage of the proceeding.

Here are the defences that actually make a difference:

Charter Right to Counsel Violations: Police must advise you of your right to speak to a lawyer immediately upon arrest and must give you a meaningful opportunity to do so before breath testing begins. Where they fail to do this — or fail to hold off on testing until you have had a real opportunity to reach counsel — the breathalyzer evidence may be excluded. Without that evidence, the blood alcohol concentration charge frequently cannot proceed.

Unlawful Traffic Stop: Police must have lawful authority to stop your vehicle. A random stop without any authorized basis may constitute an arbitrary detention, and evidence obtained following that stop may be excluded.

Instrument Malfunction and Maintenance Records: The Approved Instrument used in your test must be properly maintained, regularly calibrated, and in good working order. Gaps in maintenance records, failed calibration results, or irregularities in the instrument’s service history can support a challenge to the reliability of the breath readings.

Procedural Non-Compliance: The breath test procedure includes mandatory requirements — including a mandatory observation period before testing to ensure you have not consumed anything that could affect the reading. Failure to observe these requirements can invalidate the test results.

The Two-Hour Presumption Challenge: The Crown relies on a statutory presumption that breath test results reflect your blood alcohol level at the time of driving. Where there was a significant time gap between driving and testing, or where you consumed alcohol after driving and before the test, this presumption can be challenged through expert evidence.

Care or Control Challenges: If you were charged with care or control rather than actual operation, a defence based on the absence of realistic risk that the vehicle would be set in motion — depending on where you were, where the keys were, and what your intentions were — may be available.

Frequently Asked Questions — DUI Charges in Toronto

Q1: Will I definitely get a criminal record if charged with DUI in Toronto?

A charge is not a conviction. Being charged with impaired driving in Toronto means the Crown believes they have sufficient evidence to proceed — it does not mean a conviction is inevitable. An experienced DUI defence lawyer reviews the specific evidence in your case and identifies every available defence — from Charter violations that may result in evidence being excluded to procedural challenges that undermine the Crown’s case. Many DUI charges in Ontario are resolved without a conviction through successful pre-trial applications, Crown negotiations, or acquittals at trial. The outcome depends heavily on the quality of the legal representation you retain and how early in the process that representation is involved. Contact Costa Law Firm at (416) 535-6329 for a confidential consultation to discuss the specific facts of your case.

Q2: Can I drive after being charged with DUI in Ontario?

No. The immediate 90-day administrative licence suspension imposed under Ontario’s Highway Traffic Act takes effect at the roadside the moment you are charged with impaired driving. You cannot drive during this suspension period regardless of the eventual outcome of the criminal proceedings. Driving while suspended is a serious additional offence. Once the administrative suspension period ends, your ability to drive may still be subject to conditions — including ignition interlock requirements — depending on the stage of your criminal proceedings and any conditions attached to your release. Your lawyer at Costa Law Firm will advise you specifically on what you can and cannot do regarding driving throughout the entire process.

Q3: What is the difference between the administrative licence suspension and the criminal driving prohibition?

These are two completely separate consequences that operate on different timelines and under different legislation. The administrative licence suspension is imposed immediately at the roadside under Ontario’s Highway Traffic Act — it is automatic, does not require a court proceeding, and lasts 90 days for a first charge regardless of whether you are ultimately convicted. The criminal driving prohibition is a court-imposed penalty under the Criminal Code that takes effect only upon conviction — for a first offence, a minimum of one year — and is served following the completion of the administrative suspension. In practice, this means a person convicted of impaired driving in Ontario faces both an immediate administrative suspension and a subsequent court-ordered prohibition that extends their total period without driving privileges significantly beyond 90 days. Understanding both consequences — and the conditions for licence reinstatement — is something your Costa Law Firm lawyer will walk you through specifically and clearly.

Q4: What happens if I refused to blow into the breathalyzer when the police asked?

Refusing or failing to provide a breath sample when lawfully demanded by a police officer is a criminal offence under the Criminal Code — section 320.15 — and carries the same penalties as an impaired driving conviction. This means the refusal itself does not escape the legal consequences of a DUI charge — it simply changes the specific charge you are facing. However, a refusal charge can be defended. The demand made by the officer must have been lawful — made on proper grounds, following proper procedure, and with a valid device. Where the demand was not lawful, failure to comply with it is not an offence. Costa Law Firm’s criminal defence team analyzes the specific circumstances of the demand and the refusal to identify every available defence. Contact us at (416) 535-6329 for a confidential consultation.

Q5: How long does a DUI case take to resolve in Toronto?

The timeline for a DUI case in Toronto varies significantly depending on the complexity of the case, the specific defences being pursued, court scheduling, and whether the matter proceeds to trial. A case that resolves through pre-trial negotiation or a successful Charter application may conclude within six to twelve months of the charge being laid. A matter that proceeds to a full trial before a judge may take twelve to twenty-four months or longer depending on court availability in Toronto. Throughout the process, your Costa Law Firm lawyer keeps you informed of the timeline at every stage and manages the proceedings as efficiently as possible without compromising the quality of your defence. The length of the process is not wasted time — it is the time your lawyer uses to build the strongest possible case on your behalf.
