Operation While Impaired Causing Harm

Operation while impaired causing bodily harm (alcohol) is a serious Canadian criminal offence that targets drivers whose alcohol impairment leads to injuries. Under the Uniform Crime Reporting (UCR) system, this offence is coded as UCR Code 9220. It is prosecuted under Criminal Code section 320.14(2) and is classified as a hybrid offence, meaning the Crown can choose to proceed either summarily or by indictment. The focus of this offence is public safety: when a person operates a vehicle while their ability is impaired by alcohol and another person suffers bodily harm, they may be charged with operation impaired bodily harm.

The Legal Definition

320.14(2) Everyone commits an offence who commits an offence under subsection (1) and who, while operating the conveyance, causes bodily harm to another person.

In plain English, section 320.14(2) creates an aggravated form of impaired driving. First, the Crown must prove that you committed one of the basic impaired operation offences under section 320.14(1) – for example, operating while your ability was impaired by alcohol, or having a blood alcohol concentration (BAC) of 80 mg or more of alcohol in 100 mL of blood within two hours of driving. Second, they must prove that, while you were operating the vehicle (the Criminal Code uses the broader term “conveyance”), you caused bodily harm to another person.

“Bodily harm” is defined in section 2 of the Criminal Code as any hurt or injury that interferes with a person’s health or comfort and is more than merely transient or trifling. That covers a wide range of injuries – from broken bones and concussions to more serious trauma – as long as the harm is more than a minor, short‑lived discomfort. Under the 2018 reforms reflected in Part VIII.1 of the Criminal Code, the Crown no longer needs to show that the impairment itself contributed to the injuries; they must prove only that the driver was impaired (or over the legal BAC) and that their driving caused the bodily harm.

Penalties & Sentencing Framework

• Offence classification: Hybrid (Crown may proceed by indictment or summary conviction).
• Maximum penalty (indictment): Up to 14 years’ imprisonment.
• Maximum penalty (summary conviction): Up to 2 years less a day in jail and/or up to a $5,000 fine.
• Mandatory minimum – first offence: $1,000 fine.
• Mandatory minimum – second offence: 30 days’ imprisonment.
• Mandatory minimum – each subsequent offence: 120 days’ imprisonment.
• Enhanced first‑offence fines (high BAC):
  • BAC ≥ 120 mg but < 160 mg: minimum $1,500 fine.
  • BAC ≥ 160 mg: minimum $2,000 fine.

Because operation while impaired causing bodily harm is a hybrid offence, the Crown chooses whether to proceed summarily (for less serious cases) or by indictment (for more serious circumstances). This election affects the available maximum penalties, procedural rights (such as potential jury trial on indictment), and the overall complexity and length of the proceedings. However, the statutory mandatory minimums apply regardless of election: even on a summary proceeding, a second conviction must carry at least 30 days in jail, and a third or subsequent conviction must carry at least 120 days.

The mandatory minimum fine of $1,000 for a first conviction is the floor, not the norm. Courts routinely go higher depending on factors such as the seriousness of the bodily harm, prior driving record, level of alcohol, and aggravating circumstances (e.g., excessive speed, multiple victims, presence of children). If the underlying offence is based on an “over 80” BAC reading under section 320.14(1)(b), and the BAC was 120 mg% or higher, the enhanced minimum fines of $1,500 or $2,000 apply, even where bodily harm is involved.

On the upper end, an indictable conviction for operation impaired bodily harm can result in lengthy penitentiary sentences, measured in multiple years, especially where there is serious or permanent injury, a very high BAC, or prior impaired driving convictions. For less serious injuries and first-time offenders, sentencing might focus more on shorter custodial terms or community-based penalties (where legally available), along with probation conditions, driving prohibitions, and sometimes court‑ordered participation in provincial ignition interlock programs. The 2018 reforms encourage early access to such programs to reduce repeat offending, though provincial rules vary. Sentencing remains highly individualized within the mandatory minimum and maximum framework.

Common Defenses

• Innocent intervening drink

  The “innocent intervening drink” defence is a narrow statutory exception to the blood-alcohol‑within‑two‑hours rule in section 320.14(1)(b). Ordinarily, the law makes it an offence to have a BAC of 80 mg or more within two hours of driving, which was designed to shut down manipulative defences like “bolus drinking” (claiming you only became over the limit after you stopped driving). However, Parliament preserved a limited exception where a person genuinely and innocently drank after driving without expecting any police involvement. To use this defence, the accused must prove three things: (1) they consumed alcohol only after they stopped operating the vehicle; (2) after stopping, they had no reasonable expectation that they would have to provide a breath or blood sample; and (3) their post‑driving consumption is consistent with the test result and with having been under 80 mg% at the time of driving. In an operation impaired bodily harm case, this defence would typically arise where police arrive later (for example, at the driver’s home) and demand samples in relation to an earlier collision. If the collision involved injury, courts will closely scrutinize whether it was really “reasonable” to think police would never become involved. In most injury collisions, it will be difficult to satisfy the “no reasonable expectation of testing” requirement, which sharply limits the usefulness of this defence.

• Procedural errors in testing

  Another line of defence in operation impaired bodily harm cases is to challenge the validity and reliability of the breath or blood testing process. Canadian law presumes that results from an approved instrument operated by a qualified technician are conclusive proof of BAC when the statutory requirements are met. To rebut this, the defence may allege that police or technicians failed to follow mandated procedures (for example, improper observation period, incorrect timing of tests, or lack of proper calibration and maintenance of the device), that the person operating the approved instrument was not duly qualified, or that the chain of custody for blood samples was compromised. For drug‑related impaired cases, there are additional protocols (standard field sobriety tests and Drug Recognition Evaluations) with detailed rules for how evaluations must be administered. Where material procedural flaws are established, the court may find the results unreliable or exclude them, undermining the Crown’s ability to prove the underlying 320.14(1) offence that is required before the bodily harm aggravation can attach.

• Charter violations related to search and seizure

  Section 8 of the Canadian Charter of Rights and Freedoms protects against unreasonable search and seizure, and section 10 guarantees the right to counsel on arrest or detention. Demands for roadside breath samples, breathalyzer tests at the station, or blood samples engage these rights. Following the 2018 reforms, police are authorized to use mandatory alcohol screening at the roadside (requiring a breath sample on an approved screening device without suspicion of impairment). However, the manner in which these powers are exercised must still comply with the Charter. Common Charter-based defences in operation impaired bodily harm cases include: failure to promptly inform the accused of the reason for detention or of their right to counsel; unreasonable delay in giving access to counsel before evidentiary testing; or obtaining breath or blood samples without lawful authority. If a Charter breach is proven and the court concludes that admitting the evidence would bring the administration of justice into disrepute, the test results or other key evidence may be excluded. Without admissible proof of impairment or over‑80 BAC, the Crown may not be able to make out the 320.14(1) offence, and the 320.14(2) bodily harm charge will fail.

Real-World Example

Imagine a driver leaving a party after consuming several alcoholic drinks. They feel “buzzed” but believe they can still drive the short distance home. On the way, they run a red light and collide with another vehicle. The other driver suffers a broken arm and a concussion. Police arrive, observe signs of impairment (slurred speech, smell of alcohol, unsteady gait), and demand a roadside breath sample followed by breathalyzer testing at the station. The breathalyzer shows a BAC of 120 mg per 100 mL of blood within an hour of driving.

In this scenario, the Crown can charge the accused with operation while impaired causing bodily harm under section 320.14(2). The basic 320.14(1) element can be proven in two ways: by showing that the driver’s ability to operate the vehicle was impaired to “any degree” by alcohol, and/or that their BAC was at least 80 mg% within two hours of driving. The bodily harm element is satisfied by the injured driver’s broken arm and concussion, which clearly interfere with health and comfort and are more than transient or trifling. Causation is established because the accused’s operation of the vehicle (running the red light) caused the collision and resulting injuries; the Crown does not have to prove that the impairment itself was the reason they ran the red light. Given the 120 mg% reading, the enhanced $1,500 minimum fine for a first offence over 120 mg would apply, and the presence of bodily harm would push the case toward a more serious sentence, potentially including a period of jail, a lengthy driving prohibition, and conditions such as counseling or participation in an ignition interlock program.

Record Suspensions (Pardons)

Operation while impaired causing bodily harm results in a permanent entry on a criminal record unless a record suspension (formerly called a pardon) is granted by the Parole Board of Canada. Because this is a hybrid offence, the waiting period for a record suspension depends on how the Crown proceeded:

• If you were convicted by summary conviction, you generally must wait at least 5 years after completing your entire sentence (including any jail time, probation, and payment of fines) before applying.
• If you were convicted by indictment, the waiting period is longer: typically 10 years after you have fully completed all aspects of your sentence.

During this waiting period, you must remain crime‑free and demonstrate good conduct. A record suspension, if granted, does not erase the conviction but sets it apart from other records in the federal database, significantly reducing its visibility in most routine criminal record checks. However, serious driving prohibitions, provincial licensing consequences, and the fact that this is a serious impaired driving offence can still have ongoing implications for insurance, employment in safety‑sensitive roles, and international travel.
