Dangerous Driving Causing Death in Ontario

The short answer

Dangerous driving causing death is one of the most serious driving offences in the Criminal Code, with a maximum sentence of life in prison. These cases are tragic for everyone involved, including the families of those who died and the driver who has been charged. They also depend heavily on technical evidence, such as collision reconstruction and vehicle data, which can and should be carefully tested.

What the Crown must prove

What happens after you are charged

1. Arrest and bail: Many people are released with conditions, often including a driving ban, while others are held for a bail hearing.
2. Disclosure: The Crown provides the reconstruction report, vehicle data, autopsy findings, video and witness statements, which can take several months.
3. Independent review: Your lawyer may retain an independent reconstruction consultant to test the police findings.
4. Your election: This offence is indictable only, so you can choose a trial by judge alone or by judge and jury. Because the maximum is life, you can also ask for a preliminary inquiry.
5. Resolution or trial: Some cases resolve through a plea to a lesser offence, while many go to trial on causation or marked departure.

The evidence in a typical case

These cases usually involve a full collision reconstruction by a specialized police team. Investigators measure the scene, examine the vehicles and estimate speed, sight lines and timing. They may download data from the vehicle's event data recorder, collect dashcam and traffic camera footage, obtain phone records and interview witnesses. A coroner's or pathologist's report will also address the cause of death.

Reconstruction is not an exact science. Estimates depend on assumptions about road friction, reaction time and vehicle behaviour, and small changes in those assumptions can lead to very different conclusions.

Penalties

• First offence: There is a minimum $1,000 fine, with a maximum of life.
• Second offence: There is a minimum of 30 days in jail.
• Later offences: There is a minimum of 120 days in jail.
• Driving prohibition: The court can ban you from driving for any length it considers appropriate (s. 320.24(5)).

The court must treat the following as aggravating factors (s. 320.22):

• More than one person was killed or injured.
• The driver was racing or driving at extreme speed.
• A child under 16 was in the vehicle.
• The driver was operating a large vehicle or driving for pay.
• The driver was prohibited from driving at the time.

Since July 15, 2026, courts can again order a driving prohibition for manslaughter and criminal negligence causing death or bodily harm involving a vehicle.

How these cases are defended

• Accident reconstruction: An independent review of police estimates of speed, sight lines and timing.
• Event data: The vehicle's data may differ from witness accounts.
• Causation: Another person's actions, road design or a vehicle defect may have been the main cause.
• Marked departure: A brief lapse may be careless driving under the Highway Traffic Act, not a crime.
• Charter rights: Police may have obtained statements, blood samples or vehicle data unlawfully.

Bail and early stages

Many people are released with conditions, often including a driving ban. What you say to police and to your insurer early on can be used later, so get advice first. See our bail hearings page.

If alcohol or drugs are alleged, the charge may be impaired driving causing death, which has different rules. See our impaired driving page.

Victims' families and impact statements

The families of those who died have the right to give victim impact statements at sentencing, and the judge must consider them. These statements are often deeply emotional. They do not decide guilt, but they can affect the sentence. Your lawyer can help you prepare for this part of the process and present your own circumstances fairly.

Effects beyond the sentence

Because the maximum is life, a conviction can make a permanent resident inadmissible for serious criminality. A conviction also brings a long driving prohibition, a provincial suspension and serious insurance consequences. The family of the person who died may also bring a civil lawsuit, which usually involves your insurer.

What to do now

• Do not speak to police, your insurer or the media before you get legal advice.
• Do not post about the collision on social media.
• Keep your vehicle's repair and maintenance records, and any dashcam footage.
• Follow every release condition exactly, including any driving ban.

Criminal negligence and manslaughter charges

In some fatal collisions, police lay criminal negligence causing death under s. 220 or manslaughter instead of, or in addition to, dangerous driving. Criminal negligence requires proof of wanton or reckless disregard for the lives or safety of others, which is a higher standard than a marked departure. These charges also carry a maximum of life, and since July 15, 2026, a court can again order a driving prohibition when a vehicle was involved.
