When people search for the difference between assault and aggravated assault in Canada, they are usually trying to understand one thing: how serious their situation is and what consequences they might face.
The short answer is this: assault does not require injury, while aggravated assault involves serious harm such as wounding, disfigurement, or endangering life.
But in practice, the difference is not always obvious. Many cases fall into a grey area between simple assault and assault causing bodily harm, and the final charge depends on medical evidence, context, and how the Crown interprets the severity of the incident. This distinction matters because it directly affects whether the case is treated as summary or indictable, the potential sentence, the defence strategy, and how the case is resolved. This guide explains how Canadian law actually distinguishes between these offences, where the line is drawn, and what it means in real cases.
Key Takeaways
- Assault (s. 265) covers a wide range of conduct — from unwanted physical contact to threats of force.
- Aggravated assault (s. 268) is the most serious form and involves wounding, maiming, disfiguring, or endangering life.
- Assault causing bodily harm (s. 267) sits between the two and is often misunderstood.
- The difference is not just about “injury” — it is about the severity, medical impact, and risk to life.
- Assault is a hybrid offence, while aggravated assault is always indictable.
- Penalties range from summary-level sentences to life-changing prison terms, depending on the charge.
- Most cases are decided on evidence, intent, and credibility, not just on what happened physically.
What Is Assault Under Canadian Law?
Section 265 of the Criminal Code defines assault broadly. A person commits assault when they: intentionally apply force to another person without consent; attempt or threaten to apply force, causing reasonable fear; or approach or obstruct someone while carrying a weapon. This means assault does not require injury.
Examples of assault: pushing, slapping, or grabbing; threatening violence during an argument; raising a fist in a way that causes fear; minor physical altercations. A key point many people misunderstand: even minimal contact can qualify as assault if it is intentional and non-consensual.
What Is Aggravated Assault?
Aggravated assault is defined under section 268 of the Criminal Code as wounding, maiming, disfiguring, or endangering the life of the complainant. This is the highest level of assault offence in Canada.
What makes it “aggravated”: serious, lasting injuries; permanent damage or disfigurement; life-threatening harm; significant medical intervention required. Unlike a simple assault charge, this charge is not about the act itself; it is about its consequences.
Assault vs. Aggravated Assault: The Real Difference
Most people assume the difference is just “more injury = aggravated.” That’s partially true, but legally, it’s more precise than that.
| Factor | Assault | Aggravated assault |
|---|---|---|
| Injury required | No | Yes (serious level) |
| Severity | Low to moderate | Extreme |
| Risk to life | Not required | Often present |
| Legal classification | Hybrid | Indictable only |
| Maximum penalty | Up to 5 years | Up to 14 years |
The key legal threshold: aggravated assault requires proof that the injuries are serious, not minor; go beyond temporary harm; and may involve permanent impact or danger to life.
Where Assault Causing Bodily Harm Fits In
The difference between assault causing bodily harm and aggravated assault is the severity of the injury: bodily harm (s. 267) means any hurt that is more than merely transient or trifling bruises, cuts, minor fractures — while aggravated assault (s. 268) requires wounding, maiming, disfigurement, or danger to life. Section 267 also covers assault with a weapon and choking, suffocation, or strangulation, and it sits between simple assault and aggravated assault. The sentencing consequences of a s. 267 convictions are covered in detail in our guide to the sentence for assault causing bodily harm in Canada.
| Charge | Typical injury level | Example |
|---|---|---|
| Assault | None or minor | Push, slap |
| Assault causing bodily harm | Noticeable injury | Bruises, cuts, and minor fractures |
| Aggravated assault | Severe injury | Broken jaw, permanent damage, life risk |
Why this matters: the Crown uses section 267 to “scale” the charge depending on medical evidence, severity of harm, and surrounding circumstances. Not every injury leads to aggravated assault; the threshold is high.
Real-World Examples
Example 1 — simple assault: a heated argument leads to a push, no injury. Likely charged as assault (s. 265).
Example 2 — assault causing bodily harm: a punch results in a broken nose. Likely charged under s. 267.
Example 3 — aggravated assault: an attack causes permanent facial disfigurement or internal bleeding. Likely charged as aggravated assault (s. 268).
Penalties and Sentencing Differences
Penalties depend on the charge, criminal history, and circumstances.
| Offence | Maximum penalty |
|---|---|
| Assault (summary) | Up to 18 months |
| Assault (indictable) | Up to 5 years |
| Assault causing bodily harm | Up to 10 years |
| Aggravated assault | Up to 14 years |
Additional consequences may include probation, no-contact orders, firearms prohibitions, immigration consequences, and a permanent criminal record.
“The difference between assault and aggravated assault is not just about whether someone was injured — it’s about how serious those injuries are and how the law classifies their impact. In many cases, the defence focuses on whether the Crown can actually prove that the harm meets the high threshold required for an aggravated charge.”
Defending Assault and Aggravated Assault Charges
Every case depends on its facts, but several core defence strategies often apply: self-defence (s. 34) where the response was reasonable in the circumstances; lack of intent accident, reflex, or reaction; consent, which applies in limited contexts but not to serious harm; challenging injury severity arguing the harm does not meet the aggravated threshold or the medical evidence is inconclusive; Charter violations leading to exclusion of evidence; and negotiation toward a lesser offence where the evidence is strong.
When to Contact a Criminal Defence Lawyer
If you are being investigated or charged, do not speak to the police without legal advice; understand that early statements can shape the case; seek legal guidance immediately. Assault cases can escalate quickly, especially when injuries are involved or allegations are reclassified.
Summary Table: Assault vs. Aggravated Assault

| Max penalty | 5 years | 14 years |
| Focus | Act itself | Consequences of harm |
Final Word
The difference between assault and aggravated assault in Canada is not just about how a situation is described; it is about how the law evaluates harm, intent, and evidence. A case that starts as a minor altercation can escalate into a serious criminal charge depending on injuries, medical findings, and legal interpretation. That is why understanding the distinction and acting early can significantly affect the outcome.

Frequently Asked Questions About Assault and Aggravated Assault in Canada
What is the main difference between assault and aggravated assault in Canada?
The main difference is the severity of harm. Assault (s. 265) does not require injury — even minimal force or threats can qualify. Aggravated assault (s. 268) requires serious harm: wounding, disfigurement, or injuries that endanger life. The legal threshold is high — the Crown must prove the harm is severe enough to meet this standard.
Can you be charged with assault even if no one was injured?
Yes. Injury is not required. You can be charged if you apply force without consent, attempt to apply force, or threaten force in a way that causes fear. Even a push, grab, or raised fist can meet the legal definition.
What qualifies as “bodily harm” in Canadian law?
Bodily harm is any injury that interferes with a person’s health or comfort and is more than minor or temporary — bruising, cuts, minor fractures, short-term impairment. Aggravated assault requires much more serious harm, often involving lasting damage or risk to life.
Is assault causing bodily harm the same as aggravated assault?
No. It is a separate offence under s. 267 sitting between assault and aggravated assault: assault requires no injury; bodily harm means moderate injury; aggravated assault means severe or life-threatening harm.
What is the maximum penalty for aggravated assault in Canada?
Aggravated assault is an indictable offence with a maximum penalty of 14 years in prison, plus a permanent criminal record, strict probation conditions, and employment and travel restrictions.
Can an assault charge be upgraded to aggravated assault?
Yes. Charges can escalate based on medical evidence, severity of injuries, or new information — for example, where injuries worsen, long-term damage is discovered, or the victim’s life is put at risk.
What are the most common defences to aggravated assault?
Self-defence; lack of intent; challenging whether the injuries meet the aggravated threshold; Charter violations; and credibility issues. Many aggravated assault cases turn on medical evidence and witness credibility.
What should you do if you are charged with aggravated assault?
Do not speak to police without legal advice, avoid contacting the complainant, preserve messages, videos, and witness information, and contact a criminal defence lawyer as early as possible.
Is there a minimum sentence for aggravated assault in Canada?
No — aggravated assault (s. 268) carries no mandatory minimum, so sentences range widely based on the injuries, intent, and the offender’s record. In practice, penitentiary terms are common where the harm is severe, and a conviction brings mandatory weapons prohibitions and other lasting orders.
What happens if you are charged with aggravated assault in Ontario?
Because aggravated assault is straight indictable, expect a bail hearing rather than automatic release, strict conditions (no contact, weapons prohibition), Crown disclosure of the medical evidence, and a process that can proceed in the Superior Court of Justice with a preliminary inquiry available. The medical threshold — whether the injuries truly amount to wounding, maiming, disfigurement, or danger to life — is usually the central battleground.
