Impaired Operation Causing Harm

Operation while impaired causing bodily harm (drugs) is a serious impaired driving offence in Canada. It applies where a person operates a motor vehicle or other “conveyance” while their ability is impaired by drugs, and that impaired driving causes bodily harm to someone else. Under the Uniform Crime Reporting (UCR) system, this is coded as UCR Code 9225. In Criminal Code terms it is a hybrid offence, meaning the Crown can choose to proceed either by summary conviction or by indictment, with very different potential maximum penalties. This page explains how the law on impaired driving drugs Canada works when bodily harm is involved, what penalties may be imposed, and which legal defenses sometimes arise.

The Legal Definition

“Everyone commits an offence who commits an offence under subsection (1) and who, while operating the conveyance, causes bodily harm to another person.”
— Criminal Code, RSC 1985, c C-46, s. 320.14(2)

Section 320.14(1) sets out the underlying impaired operation offences. In particular, paragraph 320.14(1)(a) makes it an offence to operate a conveyance while “the person’s ability to operate it is impaired to any degree by alcohol or a drug or by a combination of alcohol and a drug.” When subsection (2) is added, the law targets situations where that impaired operation actually causes bodily harm to another person. The full statutory wording is available on the Department of Justice website at section 320.14 of the Criminal Code.

In plain English, this means the Crown has to prove several key elements beyond a reasonable doubt: (1) the accused was operating a “conveyance” (which can include a motor vehicle, vessel, aircraft, or railway equipment); (2) at the time, the accused’s ability to operate that conveyance was impaired by a drug (or by a combination of alcohol and a drug); (3) while operating in that impaired state, the accused was involved in an incident—such as a collision—that resulted in bodily harm to another person; and (4) there is a factual and legal connection between the impaired operation and the injury. “Bodily harm” in Canadian criminal law generally means any injury that interferes with the victim’s health or comfort and is more than merely transient or trifling.

Impairment can be established through expert evidence (for example, a drug recognition expert), toxicological analysis of blood or other bodily substances, eyewitness accounts of erratic driving, physical signs such as poor coordination or confusion, and the overall circumstances. The law does not require the person to be incapable of driving; even a degree of impairment that affects judgment, reaction time, or coordination can qualify, so long as it is linked to the operation of the vehicle and the resulting injury.

Penalties & Sentencing Framework

• Mandatory minimum penalty: None specified for this offence under section 320.14(2).
• Maximum on summary conviction: Up to 18 months imprisonment.
• Maximum on indictment: Up to 14 years imprisonment.
• Offence type: Hybrid (can be prosecuted summarily or by indictment).

Although there is no mandatory minimum sentence written into section 320.14(2) for operation while impaired causing bodily harm (drugs), the available maximum penalties are significant, particularly on indictment. A maximum of 14 years places this offence among the more serious driving-related crimes in the Criminal Code. It reflects Parliament’s view that impaired driving causing bodily harm—whether by alcohol or drugs—poses a grave risk to public safety.

As a hybrid offence, the Crown has discretion to choose the mode of proceeding. Proceeding by summary conviction is generally reserved for less serious instances—for example, where the bodily harm is less severe, the degree of impairment is at the lower end, the accused has no prior criminal record, and the public interest can be satisfied with a lower sentencing range. In these cases, the statutory maximum is 18 months in jail, though actual sentences may range from non-custodial dispositions (such as fines and probation) to periods of incarceration, depending on the facts and the applicable sentencing principles.

If the Crown proceeds by indictment, the case is treated as more serious. The accused has greater procedural protections, but also faces much higher potential punishment—up to 14 years’ imprisonment. Indictable proceedings are more likely when the bodily harm is serious (for example, broken bones, significant long-term disability, or multiple injured victims), when there is a prior history of impaired driving or other criminality, or when the manner of driving and level of impairment demonstrate a high degree of moral blameworthiness. Sentencing judges must consider deterrence and denunciation closely in impaired driving drugs Canada cases that result in bodily harm, balancing them against factors such as the offender’s remorse, rehabilitation prospects, and personal circumstances.

Common Defenses

• Consumption after ceasing to operate

  One recognized defense in drug-impaired driving cases arises where the accused consumed the drug only after they stopped operating the vehicle, and at a time when there was no reasonable expectation that they would be required to provide a bodily substance sample. While the Criminal Code specifically addresses this concept in relation to some “over legal limit” offences (such as certain provisions in section 320.14(1)(c)), the logic can still be important in an impaired driving causing bodily harm prosecution. The accused may argue that any drugs found in their system or detected by testing were ingested after driving and therefore do not prove impairment at the time of operation. For this defense to be persuasive, the timing of consumption, the nature of the drug, expert evidence about absorption and impairment, and any witness observations become critical. If the court accepts that impairment during driving is not established beyond a reasonable doubt, the charge under section 320.14(2) cannot stand.

• Charter violations (e.g., unlawful stop, arbitrary detention)

  The Canadian Charter of Rights and Freedoms plays a central role in impaired driving enforcement. Police must respect rights such as freedom from unreasonable search and seizure (section 8), the right not to be arbitrarily detained (section 9), and the right to counsel without delay (section 10(b)). In an impaired driving drugs Canada case, evidence of impairment often comes from traffic stops, roadside screening, field sobriety tests, or blood samples. If, for example, the initial stop of the vehicle lacked legal authority, or the driver was detained longer than reasonably necessary without proper grounds, or there was an unjustified delay in allowing access to a lawyer before bodily substance samples were demanded, a court may find a Charter breach.

  Where Charter violations are proven, the accused can apply under section 24(2) of the Charter to exclude evidence obtained as a result of that breach. If the excluded evidence includes key observations of impairment or the toxicology results linking the drug to the collision, the Crown might no longer be able to prove that the accused was impaired at the time of driving or that the impairment caused the bodily harm. This can lead to an acquittal, a withdrawal of charges, or a reduction to a lesser, provable offence.

• Testing errors (e.g., breathalyzer or blood test issues)

  Although drug-impaired driving commonly involves blood or other bodily substance analysis rather than a traditional alcohol breathalyzer, similar principles about the reliability and lawfulness of scientific testing still apply. The Crown must establish that the samples were lawfully taken, properly stored, and accurately analyzed, and that any instruments used were correctly calibrated and maintained. Chain-of-custody documentation, adherence to approved procedures, qualified personnel, and correct timing of the tests all matter.

  The defense may challenge toxicology evidence by pointing to improper calibration, contamination, delays inconsistent with statutory requirements, or departures from standard protocols. They may also call expert evidence to question whether the detected drug levels actually corresponded to impairment at the time of driving, given the particular substance’s pharmacology and the interval between driving and sampling. If the court is left in reasonable doubt about the accuracy or legal admissibility of the testing, then the Crown may fail to prove either that the accused was impaired or that any impairment contributed to the bodily harm.

Real-World Example

Imagine driving after consuming cannabis, believing that enough time has passed and you “feel fine.” In reality, your reaction times are still slowed. As you approach a crosswalk at night, a pedestrian steps out with the walk signal. Because your reflexes and judgment are impaired, you fail to brake in time and strike the pedestrian, causing them to suffer a broken leg and other injuries. Police respond, note the odour of cannabis, red eyes, and delayed responses, and observe signs consistent with drug impairment. A trained officer conducts a drug recognition evaluation, and a blood sample is later taken under lawful authority, confirming recent cannabis use at levels associated with impairment.

In this scenario, you could be charged under section 320.14(2) with operation while impaired causing bodily harm (drugs). The Crown would try to prove that: (1) you were operating a motor vehicle; (2) your ability to drive was impaired by cannabis at the time of driving; and (3) that impairment contributed to the collision that injured the pedestrian. The pedestrian’s broken leg clearly qualifies as bodily harm under the Criminal Code. If convicted, the court would look at factors such as the seriousness of the injury, your level of impairment, your driving record, and any prior criminal history in deciding whether to proceed summarily or by indictment and what sentence is appropriate within the statutory limits.

Record Suspensions (Pardons)

Because operation while impaired causing bodily harm (drugs) under section 320.14(2) is a hybrid offence, eligibility for a record suspension (pardon) depends on how the Crown proceeded and what conviction was entered. For hybrid offences, Canadian law treats them as indictable for many purposes unless and until the Crown elects summary, but for record suspension waiting periods the actual mode of conviction is crucial.

If you are convicted by summary conviction, you typically must wait at least five years from the completion of your entire sentence—this includes custody, probation, fines, and any driving prohibitions or other conditions that form part of the sentence—before applying to the Parole Board of Canada for a record suspension. If you are convicted by indictment, the standard waiting period is ten years from the completion of all parts of the sentence. During that time, any further criminal offences can affect your eligibility and the likelihood that a record suspension will be granted. A record suspension does not erase the conviction, but it can limit its visibility in most criminal record checks, which can be important for employment, volunteering, immigration, and travel. Given the seriousness of impaired driving causing bodily harm, applicants should expect the Parole Board to look closely at rehabilitation efforts, driving behaviour since the offence, and overall risk to public safety.
