Types of Impaired Driving Charges in Ontario

The Criminal Code of Canada defines several distinct drinking and driving offences. Understanding the specific charge you face is the first step toward building an effective defence.

Impaired Driving (DUI)

Under Section 320.14 of the Criminal Code, impaired driving occurs when a person operates or has care and control of a motor vehicle while their ability to drive is impaired to any degree by alcohol, drugs, or a combination of both. The Crown does not need to prove a specific blood alcohol concentration — observable signs of impairment such as erratic driving, slurred speech, bloodshot eyes, or loss of coordination are sufficient to support a charge.

Driving Over the Legal Limit (Over 80)

A separate Criminal Code offence is committed when a driver’s blood alcohol concentration exceeds 80 milligrams of alcohol per 100 millilitres of blood. This charge relies on breath or blood sample results collected by police using an Approved Screening Device at roadside and the Intoxilyzer® 8000C at the station. A person can be charged with both impaired driving and over 80 from the same incident.

Care and Control

You do not need to be actively driving to face impaired driving charges. If you are found intoxicated in the driver’s seat of a parked vehicle with access to the keys, the Crown can charge you with care and control under the Criminal Code. The prosecution must prove there was a realistic risk you could set the vehicle in motion. Common care and control scenarios include sleeping in a parked car after drinking or sitting in a vehicle with the engine running to stay warm.

Refusal to Provide a Breath Sample

When a police officer makes a lawful demand for a breath sample — whether roadside or at the station using the Intoxilyzer — you are legally required to comply. Refusing or failing to provide an adequate sample is a criminal offence carrying the same mandatory minimum penalties as an impaired driving conviction, including fines, licence suspension, and a permanent criminal record.

Drug Impaired Driving

Impaired driving charges also apply when impairment is caused by cannabis, prescription medication, or illegal drugs. Police may use Drug Recognition Expert evaluations and Standard Field Sobriety Testing to assess drug impairment. Since cannabis legalization under the Cannabis Act, drug impaired driving enforcement has intensified across Ontario.

Dangerous Driving

Dangerous operation of a motor vehicle is a separate Criminal Code offence often charged alongside impaired driving in cases involving collisions, excessive speed, or erratic driving behaviour. Dangerous driving penalties include up to 10 years imprisonment when bodily harm results and life imprisonment in cases involving death. A DUI lawyer experienced in defending dangerous driving charges can challenge the Crown’s evidence on both the impairment and the manner of driving.

Your rights

What Happens When You Are Charged with Impaired Driving

Understanding the DUI arrest process in Ontario helps you protect your rights from the moment police initiate a traffic stop through to your release on bail conditions.

1. The Traffic Stop and Roadside Screening

Most impaired driving charges begin at a RIDE program checkpoint, a roving check stop by the Ontario Provincial Police, or a traffic stop based on observed driving behaviour. Police can demand a roadside breath sample from any driver they lawfully stop. If the Approved Screening Device registers a fail or the officer observes signs of impairment, you will be arrested.

2. Arrest and Your Right to a Lawyer

Upon arrest, police must inform you of the reason for detention and your right to counsel under Section 10(b) of the Canadian Charter of Rights and Freedoms. Exercise this right immediately and contact a DUI lawyer before providing any statements to police.

3. Breathalyzer Testing at the Police Station

Two evidentiary breath samples are collected at the police station using a breathalyzer. These samples, not the roadside screening result, form the admissible evidence the Crown relies on to prove the over 80 charge. Strict procedural requirements govern calibration, maintenance, and operation of the instrument.

4. Release Conditions and Bail

Following a DUI arrest in Ontario, you face an immediate 90-day administrative licence suspension and 7-day vehicle impoundment before any criminal conviction. Bail conditions typically include a driving prohibition and abstaining from alcohol.

Case Strategy

How a DUI Lawyer Defends Your Case

Challenging the Evidence Against You

  • Breathalyzer and Intoxilyzer challenges: Disputing calibration records, maintenance logs, operator certification, and administration of breath tests. Faulty instruments produce unreliable blood alcohol concentration results that can be excluded from evidence.
  • Rising blood alcohol content defence: Arguing your BAC was below the legal limit while driving but rose above 80 milligrams after you stopped. Expert toxicologist testimony on absorption rates is critical to this defence.
  • Field sobriety test challenges: Standard Field Sobriety Tests are subjective and influenced by medical conditions, fatigue, anxiety, and environmental factors. Improper administration weakens the prosecution’s impairment evidence.
  • Medical and physiological defences: Diabetes, GERD (acid reflux), and ketosis can produce false positive breath test readings. Neurological conditions can mimic signs of impairment during sobriety testing.
  • Cross-examination of the arresting officer: Contradictions between police notes, testimony, and camera footage undermine the prosecution’s case. Procedural errors are powerful defence tools.
  • Expert witnesses: Our DUI lawyers retain toxicologists, accident reconstructionists, and medical specialists to challenge Crown evidence with independent scientific analysis.

Challenging Your Rights and the Process

  1. Unlawful traffic stop: If police lacked lawful authority or reasonable grounds to stop your vehicle, evidence obtained after the stop may be inadmissible.
  2. Charter rights violations: Breaches of Section 8 (search/seizure), Section 9 (arbitrary detention), Section 10(b) (right to counsel), or Section 24(2) (exclusion of evidence) are among the most effective DUI defences. Delays in access to a lawyer can result in breath test evidence being excluded at trial.
  3. Care and control challenges: Demonstrating no realistic risk of setting the vehicle in motion can defeat care and control charges even when intoxication is not disputed.
  4. Police misconduct and racial profiling: Evidence obtained through improper conduct, including racial profiling during traffic stops, can be challenged and excluded.

Lasting Impact

Consequences of a DUI Conviction Beyond the Courtroom

How a DUI Affects Your Life, Career, and Freedom to Travel

  • Permanent criminal record affecting employment, volunteering, housing, and professional licensing on background checks.
  • Insurance premium increases — convicted drivers face dramatically higher rates and high-risk classification for years.
  • Employment and professional licence consequences — security clearance revocation, regulatory body disciplinary action, and job loss for nurses, teachers, police officers, and commercial drivers.
  • US travel restrictions — US Customs and Border Protection officers have discretion to deny entry to anyone with an impaired driving conviction. A US entry waiver may be required.
  • Record suspension (pardon) eligibility — minimum 5 years after sentence completion for summary conviction offences, 10 years for indictable offences.

Post-Conviction Programs and Requirements in Ontario

  • Ignition interlock device (IID) must be installed before driving privileges are restored — zero-alcohol breath reading required before the engine starts, with installation and monthly rental fees.
  • Back on Track program — mandatory 11-month remedial measures program ($634) administered by the Registrar of Motor Vehicles for licence reinstatement.
  • Licence reinstatement requires completing all court-ordered conditions, the interlock program, and Back on Track before the Ministry of Transportation restores driving privileges.

FAQs

Frequently Asked Questions About DUI Charges

Can a DUI charge be dismissed in Ontario?

Yes. DUI charges can be dismissed if police failed to follow proper procedures, Charter rights were violated, breath testing equipment was improperly calibrated, or evidence does not support the charge. An experienced DUI lawyer reviews the investigation to identify grounds for dismissal or acquittal.

What is the difference between DUI and DWI in Canada?

DUI (driving under the influence) and DWI (driving while impaired) are informal terms — neither is an official Criminal Code offence name. The actual charges are impaired driving, over 80mg blood alcohol concentration, refusal to provide a sample, and dangerous operation. DUI and DWI describe any drinking and driving or drug impaired driving charge.

Will I get a criminal record for a first-time DUI?

Yes. A first-offence impaired driving conviction results in a permanent criminal record, minimum $1,000 fine, and minimum 1-year driving prohibition. Consulting a DUI lawyer before pleading guilty is critical — viable defences may result in the charge being dismissed.

Can I travel to the United States with a DUI conviction?

A DUI conviction may result in denied entry at the US border. US Customs and Border Protection officers have discretion to refuse admission. A US entry waiver may be required for cross-border travel.

How long does a DUI stay on my record in Ontario?

A first-time DUI conviction stays on your driving record for 3 years without licence suspension, 6 years with suspension. Multiple convictions may remain indefinitely. The criminal record is separate and permanent unless a record suspension (pardon) is granted.

Should I plead guilty to a DUI without consulting a lawyer?

Never. Impaired driving law is technically complex, and viable defences — Charter rights violations, breathalyzer calibration issues, procedural errors — are not obvious without legal expertise. Pleading guilty without a DUI lawyer means potentially giving up a strong defence.

What is the legal blood alcohol limit in Ontario?

The criminal limit is 80 milligrams of alcohol per 100 millilitres of blood (“over 80” or “.08”). Ontario also imposes administrative penalties in the warn range between 0.05 and 0.08 BAC, including a 3-day licence suspension for a first occurrence.
