What the Crown Must Prove
To secure a conviction for assault under section 266 of the Criminal Code, the Crown must prove three elements beyond a reasonable doubt:
- The accused intentionally applied force to the complainant — or attempted or threatened to apply force while having the present ability to carry out the threat
- The complainant did not consent to the application of force
- The accused had no lawful justification for the force — such as self-defence, defence of property, or defence of another person
If the Crown fails to prove any one of these elements, the result is an acquittal. This is the starting point for every assault defence: identifying which elements the Crown can and cannot prove with the available evidence.
Self-Defence Under Section 34
Self-defence under section 34 of the Criminal Code is the most commonly raised defence to assault charges. If accepted, it results in a complete acquittal.
To establish self-defence, the accused must show:
- They believed on reasonable grounds that force was being used or threatened against them or another person
- They acted for the purpose of defending themselves or another person
- The act committed was reasonable in the circumstances
The court considers multiple factors when assessing reasonableness: the nature of the force or threat, the extent to which force was imminent, whether there were other means available to respond, the relative size and physical capabilities of the parties, prior history between the parties, and the proportionality of the response.
Self-defence does not require a perfectly proportional response. But the response must be reasonable in the circumstances as the accused perceived them. For a detailed analysis of how self-defence applies in domestic situations, see our guide on self-defence in domestic assault cases.
Consent as a Defence
Consent is a defence to assault where both parties voluntarily agreed to the physical contact. This arises most often in mutual fights, contact sports, and rough physical play. If the complainant consented to the fight, the Crown cannot prove the absence of consent — and the assault charge fails.
However, the Supreme Court of Canada limited this defence in R v. Jobidon. Consent is not available as a defence where the accused intended to cause serious bodily harm. This means consent can defend against a common assault charge arising from a mutual bar fight, but it cannot defend against an assault causing bodily harm charge where serious injury was intended or resulted.
The practical effect: if a consensual fight resulted in no serious injury, consent remains a viable defence. If the fight caused serious harm, the Crown can argue the consent was vitiated and proceed on the more serious charge.
Defence of Property Under Section 35
Section 35 of the Criminal Code provides a defence for a person who uses reasonable force to protect property they are in peaceable possession of. This defence applies when someone is trespassing, damaging, or taking the accused’s property, and the accused used reasonable force to prevent or stop the interference.
The same reasonableness standard applies as in self-defence: the force used must be proportionate to the threat to the property, and the accused must have believed on reasonable grounds that force was necessary. Lethal force to protect property alone is almost never considered reasonable. But physical force to remove a trespasser or to prevent theft or property damage can fall within section 35.
Charter Rights Violations That Can Get Charges Dropped
Even when the underlying evidence is strong, Charter violations during the arrest and investigation can result in evidence being excluded or charges being stayed. The most common Charter issues in assault cases:
Right to counsel (section 10(b)). Every person arrested or detained has the right to be informed of the reason for arrest and to speak with a lawyer without delay. If the police failed to inform the accused of their right to counsel, delayed access to a lawyer, or continued questioning after the accused requested counsel, any statements made may be excluded under section 24(2) of the Charter. In many assault cases, the accused’s statement to police is a critical piece of evidence — excluding it can be fatal to the Crown’s case.
Unreasonable search (section 8). If the police searched the accused’s person, vehicle, or home without a warrant and without lawful authority, any evidence obtained may be excluded. This can include photographs, clothing, or physical evidence connecting the accused to the alleged assault. For more on search issues, see our guide on police vehicle searches in Ontario.
Arbitrary detention (section 9). If the police detained the accused without reasonable grounds — for example, based on an unverified complaint or without forming the necessary subjective belief that an offence was committed — the detention may be arbitrary. Evidence obtained as a result of an arbitrary detention can be excluded.
Trial within a reasonable time (section 11(b)). Under the Jordan framework, if the case exceeds the presumptive ceiling of 18 months in provincial court (or 30 months in Superior Court) due to institutional delay, the accused can apply for a stay of proceedings — the charge is dismissed entirely.
Plea Bargain Options: Resolving Without a Criminal Record
Not every assault case goes to trial. In many cases, the most effective outcome is a negotiated resolution that avoids a criminal record entirely.
Peace bond (section 810). A peace bond is a court order requiring the accused to keep the peace and be of good behaviour for up to 12 months, usually with conditions such as no contact with the complainant. In exchange, the Crown withdraws the assault charge. The accused does not plead guilty and does not receive a criminal record. Peace bonds are the most common resolution for contested domestic assault cases and minor assault charges where the evidence is not overwhelming.
Withdrawal of charges. The Crown may withdraw the charge entirely if the evidence is insufficient, the complainant is uncooperative, or the case does not meet the Crown’s screening standard of a reasonable prospect of conviction. A withdrawal ends the matter completely — no record, no conditions, no consequences.
Diversion programs. Some Ontario jurisdictions offer diversion (also called alternative measures or direct accountability) for first-time offenders facing minor assault charges. The accused completes conditions set by the diversion program — typically counselling, community service, or a charitable donation — and the Crown withdraws the charge upon completion.
Discharge (absolute or conditional). If the accused pleads guilty or is found guilty, the court may grant a discharge under section 730 of the Criminal Code. An absolute discharge means no criminal record immediately. A conditional discharge means no criminal record after a period of probation (typically 12 months) if the conditions are met. Discharges are commonly granted for first-time assault offenders who have taken rehabilitative steps.
The Role of Witnesses and Video Evidence
Many assault cases come down to credibility — the complainant’s word against the accused’s. Defence lawyers challenge the Crown’s witnesses through cross-examination, focusing on:
- Inconsistencies between the complainant’s statement to police and their testimony in court
- Contradictions between the complainant’s account and physical evidence or other witness testimony
- Motive to fabricate — particularly in domestic assault cases where custody disputes, separation, or immigration issues may influence the complaint
- Prior inconsistent statements or a history of making false allegations
Video evidence can be decisive. Surveillance footage, dashcam recordings, and cell phone videos can show that the accused acted in self-defence, that the complainant was the initial aggressor, that the alleged force did not occur as described, or that the accused was not present at all. Defence counsel routinely obtain and review video from businesses, traffic cameras, and third-party witnesses.

Timeline of an Assault Case in Ontario
Understanding the typical timeline helps manage expectations and identify strategic opportunities at each stage.
- Arrest and release. The accused is arrested, often at the scene or shortly after. For most assault charges, the accused is released from the police station on an undertaking with conditions — typically a no-contact order with the complainant. In more serious cases (assault causing bodily harm, aggravated assault), a bail hearing may be required before release.
- First appearance (2–4 weeks). Procedural appearance to receive disclosure. If the accused has a lawyer, the lawyer typically attends on their behalf.
- Disclosure review (4–8 weeks). The defence reviews the Crown’s evidence: police notes, witness statements, 911 recordings, photographs, medical records, and any video evidence. This is where the strength of the Crown’s case is assessed and defences are identified.
- Crown pre-trial (1–2 months). The defence lawyer meets with the Crown attorney to discuss the case. This is where resolution discussions happen — peace bond, diversion, withdrawal, or plea terms. If no resolution is reached, the matter is set for trial.
- Judicial pre-trial. In some cases, a meeting with a judge to narrow the issues and discuss resolution. The judge provides a non-binding indication of the likely sentence, which can inform the decision to resolve or proceed to trial.
- Trial (6–14 months from charge). If the case is not resolved, it proceeds to trial. Most assault trials in provincial court take half a day to two full days, depending on the number of witnesses and the complexity of the evidence.
Provocation and Sentencing
Provocation by the complainant is not a defence to assault — it will not result in an acquittal. However, provocation is a mitigating factor at sentencing that can reduce the sentence imposed after a conviction.
If the complainant engaged in behaviour that provoked the accused — verbal abuse, taunting, threats, or initial physical aggression that fell short of justifying self-defence — the court can consider this when determining an appropriate sentence. A provoked assault typically attracts a lighter sentence than an unprovoked one.
In some cases, evidence of provocation can also support a self-defence argument under section 34. If the complainant’s provocation amounted to a use or threat of force, the accused’s response may be justified as self-defence — provided the response was reasonable in the circumstances.
Is Beating an Assault Charge Realistic?
Yes, but it depends on the evidence. Assault charges are among the most commonly withdrawn, resolved, and acquitted offences in Ontario criminal courts. The reasons are structural: many assault cases involve one-on-one encounters with no independent witnesses, the complainant’s credibility is often contested, self-defence is frequently raised, and the evidence is often circumstantial.
The most important variable is the quality of the defence work. A thorough review of the disclosure, identification of Charter issues, retention of expert evidence where appropriate, and effective cross-examination of the Crown’s witnesses are what separate a strong defence from a weak one.
