Failure to Comply: Accident Death

Under Canadian law, the offence of failure or refusal to comply with demand, accident resulting in deathfailure comply accident death, it is set out in Criminal Code section 320.15(3). This offence targets situations where a driver, knowing (or being reckless about whether) they were involved in a fatal collision, refuses or fails to provide a legally required breath or blood sample after a police demand. Because the accident has resulted in death, this conduct is classified as an indictable offence with a maximum penalty of life imprisonment, reflecting Parliament’s view that obstructing impaired driving investigations in fatal cases is extremely serious.

The Legal Definition

“Everyone commits an offence who commits an offence under subsection (1) and who, at the time of the failure or refusal, knows that, or is reckless as to whether, they were involved in an accident that resulted in the death of another person or in bodily harm to another person whose death ensues.”

(Criminal Code, R.S.C. 1985, c. C-46, s. 320.15(3))

In plain terms, section 320.15(3) builds on the basic refusal offence in section 320.15(1) and makes it much more serious when a death is involved. To convict under this subsection, the Crown must first prove that the person committed the base offence in s. 320.15(1): that they knowingly failed or refused, without reasonable excuse, to comply with a lawful demand made under section 320.27 or section 320.28 of the Criminal Code. Those sections cover demands for roadside breath tests, bodily substance tests, physical coordination tests, evidentiary breath tests, and blood samples.

Once the base refusal is established, the Crown must then prove that, at the time of the refusal or failure, the accused either knew they had been in an accident that caused a death, or at least was reckless as to whether an accident they were involved in resulted in death or in bodily harm that later caused death. The law is broad enough to capture both immediate fatalities and situations where a victim is injured in the collision and dies later from those injuries. Importantly, the Crown does not need to prove that the refusal itself caused the death—only that the accident resulted in death and that the accused refused the lawful demand in that context. The full statutory wording can be found on the Justice Laws Website at section 320.15.

Penalties & Sentencing Framework

• Offence type: Indictable only (no summary option).
• Maximum penalty: Life imprisonment (s. 320.21).
• Mandatory minimum penalties (s. 320.21):
  • First offence: minimum fine of $1,000.
  • Second offence: minimum 30 days’ imprisonment.
  • Each subsequent offence: minimum 120 days’ imprisonment.
• Mandatory driving prohibition (s. 320.24):
  • First offence: at least 1 year prohibition.
  • Second offence: at least 2 years prohibition.
  • Subsequent offences: at least 3 years prohibition.
  • Courts may impose longer, including very long or lifetime bans in extreme cases.

Unlike some impaired driving offences that are “hybrid” (allowing the Crown to proceed summarily in less serious cases), section 320.15(3) is always prosecuted by indictment. This reflects Parliament’s view that refusing or failing to provide samples in a fatal accident is among the gravest transportation offences, sitting alongside impaired driving causing death and dangerous operation causing death. An indictable proceeding engages more formal processes: the accused generally has the right to elect trial in superior court with or without a jury, there may be a preliminary inquiry, and sentencing ranges are far higher.

The maximum penalty of life imprisonment under section 320.21 sets the outer boundary of judicial discretion. Typical sentences will be lower and must remain proportionate to the specific facts, but the availability of a life sentence signals just how seriously the law views a failure comply accident death situation. Judges must also apply mandatory minimums based on the offender’s record: a minimum $1,000 fine for a first conviction, then escalating to 30 days and 120 days of jail for second and further convictions. Courts cannot go below these minimums unless a mandatory minimum is found unconstitutional in a particular case, which is generally rare and requires complex Charter analysis.

On top of jail or fines, driving prohibitions are mandatory under section 320.24. The court must prohibit the person from operating the type of conveyance involved (commonly motor vehicles) for at least one, two, or three years depending on whether it is a first, second, or subsequent offence. Judges can set much longer prohibitions when warranted, especially in repeat or highly aggravated fatal cases. For many people, these prohibitions have life-altering consequences, particularly if their employment or family responsibilities depend on driving.

Common Defenses

• 1. The demand was not made lawfully.

  To prove a section 320.15(3) offence, the Crown must show that the refusal or failure related to a lawful demand made under section 320.27 or section 320.28. That means the officer must have had the statutory grounds (for example, reasonable grounds to suspect or reasonable grounds to believe, depending on the type of test), must have made the demand within the time limits (generally within three hours of driving), and must have clearly communicated the demand as a formal legal requirement. If the officer lacked the required grounds, used the wrong kind of demand, made it too late, or failed to properly inform the driver that this was a legal demand and not a mere request, the underlying offence in s. 320.15(1) may not be made out. Without a valid base offence, the aggravated 320.15(3) charge cannot stand.

• 2. Reasonable excuse for non-compliance.

  The wording of section 320.15(1) requires that the Crown prove a failure or refusal “without reasonable excuse.” This is not a separate defence raised after the fact; it is part of what the Crown must disprove beyond a reasonable doubt. A reasonable excuse is fact-specific but can include genuine physical or medical impossibility (for example, a serious chest injury preventing a proper breath sample, or a medical condition making blood draws dangerous), or extreme psychological or cognitive impairment arising from the accident (such as shock or unconsciousness). If an accused was severely injured or incapacitated due to the collision, that may explain an apparent failure and prevent conviction. However, simply not wanting to provide a sample, being afraid of the potential result, or hoping to avoid an impaired charge is not a reasonable excuse.

• 3. Lack of knowledge or recklessness about the accident.

  For the aggravated death-related version in s. 320.15(3), the Crown must prove that at the time of the refusal the accused either knew they were involved in a death-causing accident, or was reckless—meaning they were aware of a real risk that death or serious injury might have occurred and chose to ignore it. If the accused reasonably believed that there was only minor property damage and no injuries, and if no obvious signs suggested a serious or fatal injury (for example, low-speed parking-lot bump with no apparent harm), it may be difficult for the Crown to prove the necessary mental element. In such cases, while a basic refusal under s. 320.15(1) might still be possible, the aggravated 320.15(3) charge could fail. The defence may focus on visibility, lighting, speed, impact severity, what witnesses or police told the accused at the scene, and whether any injuries were apparent at the time.

• 4. Charter rights violations.

  The Canadian Charter of Rights and Freedoms overlays all impaired driving and refusal investigations. If police conduct an unlawful stop, detention, search or demand—such as stopping a vehicle without lawful authority, delaying access to counsel, or using breath or blood demands as an end-run around Charter protections—defence counsel may seek exclusion of evidence under section 24(2) of the Charter. If, for example, the only proof of a demand is a police statement obtained after breaching the right to counsel, a court might exclude that evidence. Without reliable admissible proof that a lawful demand was actually made, the Crown cannot establish the base offence in s. 320.15(1), and the 320.15(3) charge will likely fail. Charter arguments are highly technical and turn on the specific timing and content of police actions and the accused’s interactions with them.

Real-World Example

Imagine a driver who is speeding late at night and collides with another vehicle at an intersection. The other car is badly damaged; the occupants appear seriously injured and are unresponsive. Emergency services arrive, and paramedics work on one victim who is later declared deceased. Police speak with the driver, note the smell of alcohol, and make a clear, lawful demand for a roadside breath sample, followed quickly by an evidentiary breath or blood demand under sections 320.27 and 320.28. The driver is fully conscious, understands the demand, and knows there has been a serious accident. Despite this, the driver repeatedly refuses to blow into the machine or to accompany police for further testing.

In this scenario, assuming the demand was lawful and clearly explained, the driver may be charged with failure or refusal to comply with demand, accident resulting in death under section 320.15(3). The fact that one person died (or suffered injuries and later died) aggravates the refusal offence to its highest level. Whether or not the driver was actually over the legal limit or impaired is no defence: the crime is the refusal itself in the context of the fatal accident. Police will investigate the collision, the death, and the refusal. Prosecutors will consider both this aggravated refusal charge and any additional impaired or dangerous driving causing death charges that may be supported by the evidence.

Record Suspensions (Pardons)

Because this offence is indictable and carries a maximum penalty of life imprisonment, it is treated as a very serious entry on a criminal record. Under current federal policy, an individual generally must wait 10 years after completing all parts of their sentence—including any jail time, probation, fines, surcharges, and driving prohibitions—before applying for a record suspension (formerly called a pardon) for an indictable offence. The Parole Board of Canada then assesses whether the applicant has remained crime-free and is of good conduct. A record suspension does not erase the conviction but, if granted, sets it aside in the national criminal record system, which can significantly reduce the impact on employment, travel, and licencing. However, given the gravity of a failure comply accident death conviction and any related driving-death offences, applicants can expect close scrutiny of their entire post-sentence history.
