Assault Charges in Alberta: What You're Actually Facing

Assault is the most common violent offence in the Criminal Code, and one of the most misunderstood. Most people think assault requires an injury. It does not. Most people think the complainant can "drop the charges." They cannot. Most people think a heated argument with someone they live with is a private matter. In Alberta, once the police are called, it is not.

This page explains how assault is defined under section 265 of the Criminal Code of Canada, how the principal assault offences differ, what defences actually work in an Alberta courtroom, the sentencing framework after Bill C-5 reshaped conditional sentence availability, and why the early phase of an investigation — before charges are laid — is often the most consequential. Sexual offences under ss. 271 through 273 of the Criminal Code are a separate prosecution stream and are not addressed on this page. KJR Law represents people facing assault charges across Calgary and Southern Alberta.

What the Criminal Code Actually Calls "Assault"

Section 265(1) of the Criminal Code defines assault in three ways. A person commits an assault when they:

1. apply force intentionally to another person, directly or indirectly, without that person's consent;
2. attempt or threaten, by an act or gesture, to apply force to another person, where they have — or cause that person to reasonably believe they have — the present ability to do so; or
3. accost or impede another person, or beg, while openly wearing or carrying a weapon or an imitation of one.

Two things flow from this definition. First, no injury is required — a raised fist, a step taken into someone's personal space, or a single hand on a shoulder can satisfy s. 265 if the other elements are made out. Second, consent is the central issue in most assault files.

Force applied with the complainant's consent is, by definition, not an assault — but consent has limits, and they come from two different places. Under s. 265(3), no consent is obtained where the complainant submits by reason of the application of force, threats or fear of force, fraud, or the exercise of authority. Separately, at common law an adult cannot give legally effective consent to force intended to cause serious — that is, non-trivial — bodily harm: the rule in R v Jobidon, [1991] 2 SCR 714. That common-law limit is why consent is generally unavailable once a file crosses into assault causing bodily harm or aggravated assault.

The Principal Assault Offences

The Criminal Code recognizes a hierarchy of assault offences. Each is built on the same s. 265 foundation; what changes is the seriousness of what is alleged to have happened, and the corresponding sentencing range:

• Common assault — section 266. The baseline offence. No injury required, no weapon involved. Hybrid: up to 5 years on indictment, or 2 years less a day on summary conviction.
• Assault with a weapon or causing bodily harm — section 267. Either a weapon (broadly defined — a bottle, a vehicle, a household object) was used or threatened, or the complainant sustained "bodily harm" as defined in s. 2 of the Criminal Code: "any hurt or injury to a person that interferes with the health or comfort of the person and that is more than merely transient or trifling in nature." The leading appellate application of the standard is R v Moquin, 2010 MBCA 22. Hybrid: up to 10 years on indictment.
• Aggravated assault — section 268. The complainant was wounded, maimed, disfigured, or their life endangered. Indictable only. Up to 14 years.
• Assault of a peace officer — section 270 and its companions, s. 270.01 (with a weapon or causing bodily harm) and s. 270.02 (aggravated). Mirrors the assault hierarchy with peace officers as the protected complainant. Two sentencing provisions are particular to this stream: s. 718.02 directs the sentencing court to give primary consideration to denunciation and deterrence; s. 270.03 requires any sentence imposed under ss. 270(1), 270.01(1), or 270.02 committed against a "law enforcement officer" (as defined in s. 445.01(4)) to be served consecutively to any other punishment imposed on the offender.

The classification matters because it dictates the maximum sentence, the procedural path, and — in the most serious cases — whether the matter must be heard before the Court of King's Bench rather than the Alberta Court of Justice.

Hybrid Offences and Why the Crown's Election Matters

Common assault and assault with a weapon or causing bodily harm are hybrid offences — the Crown elects whether to proceed summarily or by indictment. The election is consequential. Summary conviction caps the maximum sentence (two years less a day after the 2019 amendments under Bill C-75) and keeps the matter in the Alberta Court of Justice. Indictment opens up the higher maximum penalties, raises the spectre of a trial before the Court of King's Bench with a jury, and triggers different procedural rights — including the option for a preliminary inquiry in qualifying cases. Persuading a Crown to elect summarily, where the facts justify it, is often a meaningful early objective in an assault file.

Domestic Assault: Why Alberta Treats These Files Differently

"Domestic assault" is not a separate offence in the Criminal Code. It is a regular assault charge under s. 265 et seq., overlaid with a procedural and policy framework that changes how the file is investigated, prosecuted, and resolved. Alberta operates specialized domestic violence dockets in Calgary, Edmonton, and several other centres, and Calgary Police Service has a dedicated Domestic Conflict Unit. Files involving an "intimate partner" — defined broadly to include current and former spouses, dating partners, and persons with a child in common — are flagged at intake and treated under specific Crown policies that limit the Crown's flexibility to withdraw or stay charges.

If you are the accused in a domestic assault file, the consequences begin within hours, not weeks:

• A no-contact condition will be imposed on release, prohibiting any direct or indirect communication with the complainant;
• An exclusion-zone condition will typically require you to vacate the shared residence;
• If children are involved, Children's Services may engage and access conditions may follow;
• A coordinated response involving the Crown, Calgary Police Service, and community partners such as HomeFront Calgary will already be in motion before your first court appearance.

The complainant cannot withdraw the charge. That decision rests with the Crown, and Alberta's Crown policy on intimate partner violence files makes withdrawals difficult to secure on consent alone. What can move a file — and often does — is a careful assessment of the strength of the Crown's evidence, the credibility of the central witness, and the existence of corroborating or contradicting material. A timely variation of release conditions is often the first practical objective: returning home, reinstating contact with children, restoring a working life. Our domestic assault defence page sets out the release-condition, no-contact, and Children's Services issues that arise in these files in more detail.

The Defences That Actually Work

Assault is not a strict liability offence. The Crown must prove every element beyond a reasonable doubt — the application of force or its threat, the absence of consent, and the requisite intent. Each is a target.

Self-defence (s. 34). Parliament rewrote the self-defence provisions in 2013 and the Supreme Court of Canada gave them their authoritative reading in R v Khill, 2021 SCC 37. Martin J. for the majority set out the three components, conceptualized in the case law as the catalyst, the motive, and the response: (1) the accused believed on reasonable grounds that force was being used or threatened against them or another (s. 34(1)(a)); (2) the act constituting the offence was committed for the purpose of defending or protecting themselves or another (s. 34(1)(b)); and (3) the act was reasonable in the circumstances (s. 34(1)(c)), assessed against the non-exhaustive list of factors in s. 34(2) — including the nature of the threat, whether other means were available, the history of the relationship, the accused's role in the incident, and the proportionality of the response. Where the evidence raises an air of reality to all three, the burden shifts to the Crown to disprove self-defence beyond a reasonable doubt.

Defence of property (s. 35). A parallel framework permits the use of reasonable force to protect property in peaceable possession, subject to a similar reasonableness analysis.

Consent. Where the alleged force was consented to — in a sporting context, a consensual physical altercation between adults, or a medical or other lawful intervention — there is no assault. Consent is a frequent issue in bar-fight files and in some intimate partner contexts. Two limits govern: under s. 265(3) consent is vitiated where the complainant submits by reason of force, threats or fear, fraud, or the exercise of authority; and under R v Jobidon an adult cannot consent in law to force intended to cause serious, non-trivial bodily harm. Those limits are why the consent defence narrows sharply in the assault-causing-bodily-harm and aggravated-assault context.

Identity. Where the assault is alleged to have occurred in a public setting — a bar, a parking lot, an apartment building common area — the Crown's identification of the accused becomes a real issue. Surveillance footage is rarely as clear as the Crown initially claims. Witness identification is rarely as reliable as the initial police interviews suggest. Where the only witness to identification is the complainant, and the complainant's reliability is in question, the Crown's case can collapse on this element alone.

Credibility and reliability. Many assault files turn on a single witness — the complainant — telling a single version of events that the accused contests. The framework from R v W(D), [1991] 1 SCR 742 governs: if the accused's evidence is believed, acquit; if not believed but it raises a reasonable doubt, acquit; if it raises no doubt, the Crown must still prove guilt beyond a reasonable doubt on the evidence accepted. Where the complainant's account is internally inconsistent, contradicted by other evidence, or undermined by a documented motive to fabricate or exaggerate, the Crown's burden becomes very difficult to meet.

Charter breaches. Many assault files involve arrests, searches, and statements that may have been taken in violation of ss. 8, 9, 10(a), or 10(b) of the Canadian Charter of Rights and Freedoms. Statements obtained without an accused having been advised of their right to silence and right to counsel — or after a request for counsel was not facilitated — are vulnerable to exclusion under s. 24(2). The exclusion of a key statement frequently changes the trajectory of a prosecution.

Sentencing After Bill C-5

The custodial-sentence exposure on assault varies dramatically by provision. A first-time common assault on a careful factual record frequently resolves without custody — through an absolute or conditional discharge (which leaves no record on completion), a suspended sentence with probation, or a fine. A s. 267 conviction has a wider range, often including custody in serious files. A s. 268 aggravated assault conviction has historically attracted significant custodial sentences, particularly where weapons were involved or the injuries were severe.

The conditional sentence landscape shifted materially under Bill C-5. Bill C-5 (S.C. 2022, c. 15, Royal Assent November 17, 2022) removed the categorical bar in s. 742.1(c) of the Criminal Code on conditional sentences for indictable offences with maximums of 14 years or life. None of the assault offences carries a mandatory minimum, so s. 742.1(b) does not bar a CSO on any assault conviction. The result: conditional sentences are now potentially available across the full assault spectrum — including s. 268 aggravated assault, where a categorical bar previously foreclosed the option — subject to the remaining s. 742.1 gates: community safety under s. 742.1(a), consistency with the fundamental purpose and principles of sentencing, and the two-years-less-a-day sentence ceiling. The Supreme Court of Canada upheld the constitutionality of the s. 742.1 framework in its pre-Bill C-5 form in R v Sharma, 2022 SCC 39; Bill C-5 then expanded availability by statutory amendment. On a s. 268 file with mitigating personal circumstances and a sentencing record that can satisfy the safety-of-community analysis, a CSO is now a live option where it was not before November 2022.

Collateral consequences. A conviction does more than expose you to a sentence. Two distinct families of consequence follow, and they work differently — one set the sentencing court imposes as part of the sentence, the other the conviction triggers elsewhere.

Orders the sentencing court imposes as part of the sentence:

• Firearms prohibition. A conviction for aggravated assault carries a mandatory weapons prohibition under s. 109 — it is an indictable violence offence with a maximum of ten years or more. The same mandatory prohibition applies under s. 109(1)(a.1) to any indictable assault involving violence against an intimate partner, a child or parent, or a person who lives with the accused — which captures many domestic files. Assault with a weapon or causing bodily harm under s. 267, where the Crown proceeds by indictment, also falls within the mandatory s. 109 regime. For assaults outside those triggers — for example a common assault on summary conviction — the court may impose a discretionary prohibition under s. 110.
• DNA order. Aggravated assault (s. 268) and assault with a weapon or causing bodily harm (s. 267) are both primary designated offences under s. 487.04, so a DNA order is mandatory on conviction; the peace-officer offences under ss. 270.01 and 270.02 are likewise primary. Common assault under s. 266 is a secondary designated offence, where a DNA order under s. 487.051 is discretionary.

Consequences the conviction triggers outside the criminal court — not part of the sentence, but often the most serious thing about a conviction:

• Immigration. For a non-citizen, an assault conviction can engage inadmissibility under the Immigration and Refugee Protection Act. Aggravated assault in particular can amount to "serious criminality," which can lead to removal and the loss of appeal rights regardless of how long the person has lived in Canada.
• Employment, licensing, and travel. A criminal record can affect professional licensing, current and future employment, and entry to other countries, including the United States.

Because the ancillary orders are decided at sentencing, they are open to submissions; and because the downstream consequences can be severe, sentencing strategy on an assault file engages both families from the first conversation.

When the Investigation Comes Before the Charge

In Alberta, assault investigations frequently involve a window between the police taking the initial complaint and a decision being made to lay charges. That window is where the most consequential decisions are made — about whether to provide a statement to police, whether to consent to the seizure of devices, and whether the file should be steered toward charges at all. The right to silence under s. 7 of the Charter, and the right to counsel under s. 10(b), exist precisely for this phase. They are at their most useful before charges are laid, not after. If the police have contacted you in connection with an assault allegation but you have not yet been charged, call a lawyer before you call them back.

Where We Appear

We act on assault files in the Alberta Court of Justice, the Court of King's Bench of Alberta, and the Court of Appeal of Alberta. From our Calgary office we travel to court in Airdrie, Cochrane, Canmore, Okotoks, Diamond Valley, Didsbury, Strathmore, Drumheller, Hanna, Brooks, Medicine Hat, Lethbridge, Fort Macleod, Taber, Pincher Creek, and Cardston, and we appear in matters arising on the Tsuut'ina, Siksika, and Kainai (Blood Tribe) Nations.

Speak to a Lawyer Before You Speak to Police.

If you have been charged with assault, or contacted by police in connection with an assault complaint, the most useful first step is a conversation with counsel. We can advise on what to say, what not to say, what to expect at first appearance, and how to manage the early phase of a file in a way that preserves your options. The initial consultation is at no charge.
