Assault causing bodily harm is a more serious offence than simple assault under the Criminal Code, applying where the assault results in an injury that interferes with a person's health or comfort and is more than merely transient or trifling. It carries a higher maximum penalty than simple assault. Common defences include self-defence, consent, identification issues, and challenging whether the injury actually meets the legal threshold of "bodily harm."
- Bodily harm means an injury that interferes with health or comfort and is more than merely transient or trifling — a legal threshold, not just any physical contact.
- Assault causing bodily harm carries a significantly higher maximum penalty than simple assault.
- Self-defence and consent can both be complete defences depending on the circumstances.
- Medical evidence documenting the alleged injury is often central to how these cases are contested.
- Domestic and non-domestic assault causing bodily harm cases can follow different procedural paths.
- Early legal advice matters — how the incident is characterized early on can shape the entire case.
The Short Answer
Assault causing bodily harm is treated significantly more seriously than simple assault under the Criminal Code, because it requires the Crown to prove the assault resulted in an injury that interferes with a person's health or comfort and is more than merely transient or trifling. That added element carries a higher maximum penalty — and a corresponding set of defences and evidentiary issues that differ from a simple assault case.
What Counts as “Bodily Harm”
Bodily harm is a legal threshold, not a fixed list of injuries. Courts look at whether the injury genuinely interfered with the person's health or comfort beyond something merely transient or trifling — bruising, cuts requiring treatment, or more serious injuries can qualify, depending on the evidence. Medical records, photographs, and expert evidence are often central to establishing, or challenging, whether this threshold is actually met.
How This Differs From Simple Assault
Simple assault requires only that force was intentionally applied without consent — no particular injury needs to be proven. Assault causing bodily harm adds an additional element the Crown must establish: that the assault actually resulted in an injury meeting the bodily harm threshold. This distinction matters both for the potential penalty and for how the defence approaches the medical evidence.
Possible Penalties
Assault causing bodily harm is a hybrid offence, carrying a meaningfully higher maximum penalty than simple assault whether the Crown proceeds summarily or by indictment. The actual sentence in any given case depends heavily on the severity of the injury, whether weapons or aggravating factors were involved, your record, and the circumstances of the incident — see our guide on aggravating and mitigating factors in Ontario sentencing.
Common Defences
- Self-defence — where you reasonably believed force was being used or threatened against you, and your response was reasonable. See our full guide on self-defence under Ontario criminal law.
- Consent — in limited circumstances, such as certain contact sports, though consent has important legal boundaries.
- Identification — challenging whether you were correctly identified as the person responsible.
- The injury does not meet the bodily harm threshold — arguing the alleged injury was too minor to satisfy the legal test, which can result in a reduction to simple assault.
Even where an assault clearly occurred, whether the resulting injury legally qualifies as bodily harm is frequently a genuinely contested issue — and a successful challenge can significantly reduce your exposure.
When the Charge Arises From a Domestic Incident
Assault causing bodily harm charges arising from a domestic relationship follow some distinct procedural considerations — including specialized domestic violence court processes in many Ontario jurisdictions and particular considerations around no-contact conditions. If your charge arises from a domestic incident, our guide on whether domestic assault charges can be dropped covers this in more depth.

Frequently Asked Questions
Bodily harm is any injury that interferes with a person's health or comfort and is more than merely transient or trifling in nature. This is a legal threshold assessed on the specific facts and medical evidence, not a fixed list of injuries.
Simple assault does not require proof of any particular injury, while assault causing bodily harm requires the Crown to prove the assault resulted in an injury meeting the bodily harm threshold — and it carries a correspondingly higher maximum penalty.
Yes. If you reasonably believed force was being used or threatened against you and your response was reasonable in the circumstances, self-defence can be a complete defence, regardless of the resulting injury.
In some circumstances, yes — certain contexts, such as some contact sports, can involve legally recognized consent to physical contact. However, consent has important legal limits and does not apply to many situations, particularly where serious harm results.
It depends entirely on the severity of the injury, your record, and the specific circumstances. Outcomes range widely — some cases resolve with a discharge or non-custodial sentence, while more serious or repeat cases can result in jail.
The decision to proceed rests with the Crown, not the alleged victim — a complainant cannot unilaterally withdraw charges. That said, a complainant's position can still be a relevant factor in how the Crown approaches the case.
