Explosives Causing Harm in Canada

In Canadian criminal law, explosives causing harm Canada refers to serious offences where an explosion causes death or bodily harm, or is intended to do so. These offences are not described under a single label in the Criminal Code, but are mainly prosecuted under section 80 (breach of duty regarding explosives causing death) and section 81(1)(a) and (b) (using explosives with intent to cause serious bodily harm or death). For police and court statistics, these matters are tracked under UCR Code 1628. They are always treated as indictable offences, reflecting how dangerous and socially disruptive the misuse of explosives is.

The Legal Definition

Section 80: “Every one who, being under a legal duty within the meaning of section 79, fails without lawful excuse to perform that duty, is guilty of an indictable offence and, if as a result an explosion of an explosive substance occurs that (a) causes death… is liable to imprisonment for life.”

Section 81(1)(a): “Every one commits an offence who (a) does anything with intent to cause an explosion of an explosive substance that is likely to cause serious bodily harm or death to persons…”

Section 81(1)(b): “… with intent to do bodily harm to any person (i) causes an explosive substance to explode…”

In plain English, section 80 targets situations where a person has a related to explosives—often in a work or professional context—and their failure to meet that duty leads to a deadly explosion. The core idea is that some people (for example, demolition supervisors, mining engineers, or others handling explosives under law or regulation) have a heightened responsibility. If they breach that responsibility without a lawful excuse, and someone dies because of an explosion, they can face life imprisonment. Section 80 is therefore closely tied to negligence and breach of duty rather than direct intent to harm.

Section 81(1)(a) and (b), by contrast, focus on intentional misuse of explosives. Under section 81(1)(a), it is an offence to do anything with the intent to cause an explosion that is likely to cause serious bodily harm or death. Under section 81(1)(b), it is an offence, with intent to do bodily harm to any person, to actually cause an explosive substance to explode. These provisions do not require that someone in fact be killed or injured; the law is concerned with the deliberate, dangerous use of explosives that creates an obvious risk of serious harm or death. Full wording and context are available on the Department of Justice website at section 81 of the Criminal Code.

Penalties & Sentencing Framework

• Type of offence: Indictable only (no summary election).
• Mandatory minimum penalty: None specified for section 80 or section 81(1)(a)/(b).
• Maximum penalty: Life imprisonment where death results or where the conduct falls under the life-max provisions of sections 80 or 81(1)(a)/(b).

Because these offences are indictable only, they are prosecuted in the superior courts with full procedural protections, including the possibility of a jury trial. While Parliament has chosen not to impose a mandatory minimum sentence for these particular provisions, the presence of a life imprisonment maximum signals that courts must treat such cases among the most serious offences in Canadian criminal law. Judges retain discretion to impose lower sentences where the circumstances warrant, but they must always consider the immense public safety risk posed by explosives.

Sentencing in cases involving explosives causing death or bodily harm is highly fact‑specific. Courts will look at whether the case arises from a breach of legal duty (section 80) or from intentional violence or terror-like conduct (section 81). An intentional bombing or deliberate explosive attack is typically viewed as much more morally blameworthy than even very serious negligence. Under section 81(1)(a)/(b), the Crown generally needs to prove a specific intent—to cause an explosion likely to cause serious bodily harm or death, or to cause bodily harm to another person. This mental element tends to attract harsher penalties, especially where there is planning, premeditation, or multiple victims.

By contrast, under section 80, the focus is on whether the accused had a defined legal duty under section 79 and breached it without lawful excuse, leading to a fatal explosion. This could include failing to follow statutory safety regulations, ignoring mandatory inspection or storage requirements, or delegating critical explosive-handling tasks to unqualified staff. While still extremely serious, some section 80 cases may involve gross carelessness rather than a purpose to harm, and sentencing will reflect this difference in moral blameworthiness. However, where multiple deaths occur, or where the degree of negligence is extreme, long penitentiary terms are common and may approach sentences seen for manslaughter or criminal negligence causing death.

Common Defenses

• Lawful excuse

  “Lawful excuse” is expressly referenced in section 80 and is closely tied to how courts assess liability under section 81 as well. Under section 80, the Crown must prove not only that the accused had a legal duty and breached it, but also that they did so “without lawful excuse.” A lawful excuse may arise where the accused’s conduct, though resulting in an explosion, was authorized by law, reasonably necessary, and carried out in compliance with applicable standards. For example, a demolition supervisor who follows all statutory regulations, safety protocols, and industry best practices, yet still experiences an unforeseen explosion due to a latent defect in equipment, may be able to argue that there was no unlawful breach of duty. The accident, while tragic, might be seen as occurring despite exercising reasonable care, rather than because of a failure to discharge the legal duty.

  Within the context of section 81(1)(a) and (b), a similar concept applies: police, military, or licensed professionals who use explosives in the course of their lawful duties—such as bomb disposal, controlled detonations, or emergency building breaches—typically act under statutory authority and strict protocol. These circumstances can provide a lawful excuse or, more precisely, negate the intent to cause unlawful harm that section 81 requires. The key issue is whether the explosives were used for a legally recognized and properly controlled purpose. If the accused’s actions were consistent with their lawful mandate and proportionate to the risk, they may defeat the allegation that they acted with the proscribed intent or without lawful justification.

Real-World Example

Consider a scenario where a construction worker is assigned to assist with demolition at a large urban site. The company contracts a blasting supervisor who is legally responsible for planning and supervising the use of explosives under provincial occupational health and safety laws and federal explosives regulations. The supervisor, however, authorizes blasting without properly clearing neighbouring buildings, fails to verify that all non-essential workers and bystanders are at a safe distance, and neglects mandated checks of the wiring and timing devices. During the detonation, debris and blast force travel much farther than anticipated. Several workers are killed, and nearby pedestrians suffer serious injuries.

In this situation, police and prosecutors would examine who exactly held the legal duty under section 79 and related safety statutes—likely the blasting supervisor and potentially others in the chain of command. If the evidence shows that the responsible person failed to perform that duty without lawful excuse, and the explosion caused death, a charge under section 80 could follow, exposing the accused to life imprisonment. If, alternatively, investigators found that someone intentionally altered the blast plan or tampered with explosives in order to injure a specific co-worker, that conduct might fit more closely under section 81(1)(b), as an intentional use of explosives to cause bodily harm. The courts would then assess intent, foreseeability of serious harm, and whether the actions represented a deliberate attack rather than simple negligence.

Record Suspensions (Pardons)

Because offences involving explosives causing death or bodily harm are indictable offences with maximum penalties up to life imprisonment, they are treated as extremely serious under the federal Criminal Records Act. An individual convicted under section 80 or section 81(1)(a)/(b) may apply to the Parole Board of Canada for a record suspension (pardon), but only after a substantial waiting period. For indictable offences, the current waiting period is generally 10 years after completion of the entire sentence, including any term of imprisonment, probation, and payment of fines or surcharges. The applicant must also demonstrate that they have been of good conduct and that the suspension would provide a measurable benefit, such as improved employment prospects or reintegration into the community.

It is important to understand that a record suspension is not automatic and may be more difficult to obtain where the original conduct involved loss of life, extreme risk to the public, or intentional violence. The gravity of explosives-related offences means that decision‑makers scrutinize the underlying facts carefully. Even if a record suspension is eventually granted, it does not erase the history of the event itself; it only sets the record apart from publicly visible criminal records in most checks. Immigration consequences, security clearances, and certain types of background screening may still access the fact of a life‑max explosives conviction, so early legal advice is strongly recommended for anyone facing such charges.
