You did not pick the fight. Outside a bar on King St., on a TTC platform, in a downtown stairwell, someone came at you and you reacted, and now you are the one holding a court date. Take a breath. A charge is the beginning of the analysis, not the end of it. Canada has a complete legal framework for judging defensive force after the fact, and in a city as filmed as Toronto these cases usually turn on a few seconds of video and all the context the video missed. This page explains section 34, the nine factors, and how we run these files.

Judged frame by frame: video evidence in a filmed city

Toronto is one of the most recorded cities in the country. TTC vehicles and stations, storefront and bar systems, condo lobbies and elevators, dashcams, doorbells, and a dozen phones at any downtown corner. In a self-defence file the question is rarely whether the incident was recorded. It is what the recording shows, what it missed, and who moves fastest to preserve it.

Three realities drive our first week on these cases.

Footage disappears on a schedule. Retention varies by system and is often short, sometimes days or weeks. Police collect what supports their theory of the scene, and they do not collect everything. So our preservation letters go out in days, not months: to the venue, the neighbouring businesses, the condo board, the transit authority, anyone whose cameras faced the relevant sidewalk. The most important frame in your case may already be scheduled for automatic deletion.

Clips mislead without context. Video usually starts after the threat did. A camera that catches your punch but not the three shoves that preceded it, the bottle in the other hand, or the words that made the threat unmistakable will make a defensive reaction look like an attack. Angles flatten distance, sound is often missing, and start-point bias is real. Part of the defence is rebuilding the missing timeline through witnesses, injuries on both sides, and messages sent before and after.

Seizures have rules. Where police take phones or footage without proper authority, the Charter gives the defence remedies, up to exclusion of the evidence where its admission would bring the administration of justice into disrepute. How the video got into the Crown's hands matters, not just what it shows.

The three gates of section 34

Section 34 of the Criminal Code sets out modern Canadian self-defence in one framework with three gates, and you need all three:

• Reasonable belief: you believed on reasonable grounds that force or a threat of force was being used against you or another person;
• Defensive purpose: what you did was done for the purpose of defending or protecting yourself or that other person; and
• Reasonableness: the act you committed was reasonable in the circumstances.

Notice what the first gate does. It judges your belief in the moment, on reasonable grounds, not with the luxury of hindsight. A mistaken belief can still ground the defence if the mistake was reasonable in the situation you actually faced.

And notice who carries the load. Once self-defence has an air of reality on the evidence, the Crown must disprove it beyond a reasonable doubt. You do not have to prove you acted in self-defence; the prosecution has to prove you did not. That allocation of burden is why early, organized defence evidence changes outcomes: every witness, injury photo and preserved clip makes the Crown's job harder on all three gates at once. Most of these files arrive charged as assault; our Toronto assault lawyers page covers that offence ladder in detail.

The nine factors in section 34(2), with Toronto examples

Reasonableness is not decided on gut feel. Section 34(2) directs the court to consider the relevant circumstances of you, the other person and the act, and it lists factors. Here is the list, with the street-level version of each:

Factor	What it means on the ground
(a) The nature of the force or threat	A shove in a lineup is not a knife on a platform. Your response is measured against the threat you reasonably perceived, not the one hindsight assigns.
(b) How imminent it was and whether other options existed	An enclosed TTC car with the doors closed offers different exits than an open sidewalk. Courts weigh what was realistically available in the seconds you had, not what a map shows later.
(c) Your role in the incident	What you did before, during and after counts: who followed whom, who tried to leave, who escalated, who called 911.
(d) Whether anyone used or threatened a weapon	Bottles, belts and improvised objects count, on either side. A weapon anywhere in the mix changes what a proportionate response looks like.
(e) Size, age, gender and physical capabilities	Three against one, a smaller person facing a larger one, age, injury and training all shape what was reasonable for you specifically.
(f) The nature, duration and history of the relationship, including prior force or threats	History explains perception. A person who has been assaulted by the same aggressor before reads a raised hand differently, and the law says the court must account for that.
(f.1) Any prior communications between you	Threatening messages before the encounter are evidence of the threat you faced, which is one reason we preserve entire threads immediately.
(g) The nature and proportionality of your response	Proportionality is weighed as part of the whole picture. It is not a pass-fail math test, and the law does not demand a perfectly calibrated response from someone under attack.
(h) Whether you responded to force you knew was lawful	Fighting force you knew was lawful, a lawful arrest being the clearest example, undercuts the defence. Section 34(3) deals specifically with force used against police acting lawfully.

No single factor decides anything. The court weighs the whole situation as it appeared to you at the time, which is why the defence's job is to put the court inside your shoes at the moment of decision, not to win each row of the table separately.

The castle doctrine Canada does not have, and other proportionality myths

American law drifts across the border through television, and it loses accuracy in transit. Canada has no castle doctrine statute and no stand-your-ground statute. Sections 34 and 35 are the complete code, at home and everywhere else.

Being in your own home still matters, just through the factors rather than around them. Imminence reads differently when someone forces their way into your hallway at 3 a.m. The options realistically open to you look different in your kitchen than on a sidewalk. And the statutory factor list asks whether other means were available to respond; it does not impose a duty to flee your own home. But none of that suspends the final gate. Every route through sections 34 and 35 still ends at the same question: was the act reasonable in the circumstances.

Two more myths worth killing. First, the idea that your force must exactly match the attacker's, blow for blow. Proportionality is factor (g), one consideration among nine, and courts recognize that people defending themselves cannot measure their response with precision. Second, the idea that whoever threw the first punch automatically loses. Your role in the incident is factor (c), weighed with everything else; it is not a disqualification rule. For the province-wide version of this framework, see our Ontario self-defence guide.

He agreed to fight is not a defence plan

Bar fight files often arrive with the same theory attached: we both wanted it, so it cannot be a crime. The Supreme Court of Canada closed most of that door in Jobidon. Consent to a fistfight is vitiated, cancelled in law, where non-trivial bodily harm is both intended and caused. So mutual combat facts get argued where they actually belong, through section 34 and reasonableness, not through consent alone.

The Court's 2021 decision in Khill is the modern centrepiece for how these incidents get judged. Khill holds that your role in the incident means your conduct throughout the event: what led in, what you did in the moment, and what you did after. Courts look at the catalyst, your motive, and your response as one continuous story. An instigator can still end up acting lawfully in self-defence when the tables turn, and a person who never threw the first punch can still respond unreasonably. Nobody gets judged on a single frame, which cuts both ways and is exactly why the full timeline, not the viral clip, has to be in front of the court.

The one-punch warning

This section exists because we have sat across from good people living with it. Where an unlawful punch causes death, manslaughter does not require the Crown to prove you foresaw death. It requires only that a reasonable person would have foreseen a risk of non-trivial bodily harm from the unlawful act. One punch, a fall, a curb: that is the whole distance between an assault charge and a manslaughter charge in Canada. Our Toronto manslaughter page covers that terrain.

The practical lesson is not legal at all. When disengaging is genuinely open to you, disengage. Walking away wins the only fights that never get judged. And where the night has already gone wrong and the charge is laid, the same section 34 framework above still applies, factor by factor, with everything to fight for.

Drinking and self-defence: the credibility battleground

Most Toronto bar files feature alcohol on both sides, and it becomes a battleground over perception rather than doctrine. The Crown will use your drinking to attack your read of the threat: you misjudged, you overreacted, you remember it wrong. The defence often uses the other side's drinking to explain erratic aggression the video only half captures. Sober witnesses, timestamps, tabs and texts end up carrying weight beyond their size.

Two honest notes. Intoxication does not lower the standard your conduct is measured against; the belief gate still asks about reasonable grounds. And extreme intoxication is a separate, narrow doctrine under section 33.1 of the Criminal Code with its own 2022 rules; it is not a self-defence issue and it is not a loophole. If your file involves that territory, or genuine mental illness rather than alcohol, see our Toronto mental health defence page.

Defending someone else

Section 34 protects defence of another person in the same breath as self-defence: the belief gate expressly covers force or threats against you or another person, and the purpose gate covers defending or protecting that person. Stepping in for a friend, a partner or a stranger on the subway gets analyzed under the same three gates and the same factor list.

The distinctive risk in third-party files is arriving mid-scene. You see thirty seconds of a conflict with a longer history, and your reasonable belief gets judged on what you saw and knew at that moment. That is workable; it just makes witness evidence about what was visible and audible before you stepped in more important than usual.

For bouncers, security staff and business owners, a second authority sits nearby: the citizen's arrest power in section 494. An owner, or a person authorized by them, can arrest someone found committing a criminal offence in relation to the property, and since the 2012 amendments the arrest can also be made within a reasonable time afterward where it was not feasible for police to do it. Two hard limits ride along: the person must be delivered to police forthwith, and only reasonable force may be used. In practice, what happened during the holding is usually what the charge against the arrester is about.

Defending property: section 35 and its traps

Section 35 covers defence of property, and its architecture mirrors section 34: defined gates, then reasonableness.

The gates. You must believe on reasonable grounds that you are in peaceable possession of the property, or be assisting someone you reasonably believe is. You must reasonably believe another person is about to enter, is entering or has entered without legal entitlement, or is about to take the property, is taking it, or has just taken it, or is about to damage, destroy or make it inoperative. Your act must be done to prevent the entry or remove the person, or to prevent the taking or retake the property. And, always, the act must be reasonable in the circumstances.

The traps. Section 35(2) removes the defence where you lack a claim of right to the property and the other person is legally entitled to possess it: disputes with someone who has lawful entitlement are not section 35 territory, however heated they feel. Section 35(3) removes it against lawful law-enforcement action, such as an execution of process, unless you reasonably believed the person was acting unlawfully. And the moment a property confrontation becomes a threat to a person, the analysis shifts to section 34, where the factors above take over.

A word on weapons, because clients ask. Whether anyone used or threatened a weapon is factor (d), and it cuts on both sides: a weapon in the other hand changes what a proportionate response looks like, and anything in yours will be weighed and will usually be reflected on the charge sheet. What you will not find on this page is advice about how much force you can use in advance or anything about arming yourself. The law judges these events after the fact, on their whole circumstances, and no honest lawyer pretends otherwise.

How Toronto police and the Crown screen self-defence claims

Understanding who decides what, and when, takes most of the mystery out of these files.

At the scene, officers make fast decisions on partial information: who is standing, who is hurt worse, whose friends speak first, who looks calm and who looks wild. People who defended themselves get arrested at Toronto scenes regularly, not because the law failed but because a sidewalk at 2 a.m. is not a courtroom. If that was you, say you were defending yourself, say you want a lawyer, and then stop talking. The urge to explain everything on scene is the single biggest source of avoidable damage; scene statements get parsed word by word for months.

At the charging stage, the test police apply is about grounds to believe an offence occurred. It is not a ruling on reasonableness, and it was never meant to be. A charge means the analysis has started.

At the Crown's desk is where prepared files win early. Once self-defence has an air of reality, the Crown must ask whether it can disprove the defence beyond a reasonable doubt with admissible evidence. So we put the answer in front of the prosecutor before positions harden: preserved footage with the start of the incident, injury photographs from both sides, the witness the police never called, the messages that show who was hunting whom. Prosecutors resolve or withdraw files they expect to lose, and they expect to lose files where section 34 is loaded and aimed early.

Then process. If you were held, bail happens at the Toronto Regional Bail Centre, 2201 Finch Ave. W., which runs all adult Toronto bail including weekends. Expect conditions with real texture: no contact with the other person, no-go terms that can cover the venue or a stretch of downtown, sometimes a route you used to ride. Disclosure, including every video the investigators gathered, flows at the Ontario Court of Justice at 10 Armoury St. For the most serious allegations, the file can proceed to the Superior Court at 361 University Ave., with elections and preliminary steps decided strategically. And the Jordan ceilings, eighteen months in the OCJ and thirty in the SCJ from charge to the end of trial, get tracked from day one.

If self-defence fails, the case is not over

We build these files in layers, because betting everything on a single ruling is how people get hurt twice.

Underneath the defence itself there are usually live issues about intent and causation, and sometimes about identity in chaotic group incidents. Below those sit lesser included offences: the difference between the charge laid and the offence actually proved can be the difference in years. Alongside all of it sit resolution positions the Crown will consider once the strength of the defence evidence is plain. And where a court rejects self-defence but accepts that you acted in a genuinely defensive context that went too far, sentencing looks profoundly different than it does for gratuitous violence. Judges sentence the person and the moment, not just the verdict.

None of that is pessimism. It is what taking the whole file seriously looks like, and it is usually the layered preparation that makes the first layer, the defence itself, land harder.

Common Toronto scenarios, mapped to the framework

The condo hallway confrontation. A dispute with a visitor or neighbour turns physical steps from your own door. Expect the building's cameras to have caught some of it and missed the words that started it. Peaceable possession and section 35 may be in play for the doorway itself, but the moment it became about your safety, section 34 and its factors carry the analysis.

The TTC platform grab. Enclosed space, strangers, seconds to decide. Factor (b) does heavy lifting here: what options did you realistically have with a train wall behind you and the exits crowded. Transit footage exists; getting all of it preserved, from more than one angle, is the first job.

The bar exit swarm. Three people follow one out the door. Factors (e) and (a) frame the mismatch, prior communications inside the bar feed (f.1), and Jobidon takes the consent shortcut off the table. The clip that surfaces online will start late; the full sequence wins or loses the file.

The road rage stop. Dashcams on both cars, a dispute about who got out first. Role in the incident, factor (c), and the Khill lens on catalyst, motive and response decide how the story reads. What you did after, staying, calling 911, rendering aid, is evidence too.

The first hours after a defensive incident

What you do immediately afterward becomes part of the record, so do it deliberately.

• Call 911 yourself if you can. Being the caller matters, and the recording preserves your state of mind in the moment.
• Get medical attention and let the injuries be documented properly. Photograph them again over the following days as bruising develops.
• Leave the scene alone. Do not clean up, move objects or collect the other person's property.
• When police arrive, identify yourself, say you were defending yourself and that you want to speak to a lawyer before giving a statement, then stop talking. That sentence is not evasion; it is how careful people protect accurate facts.
• Keep what you wore, unwashed, and note every witness before the crowd scatters.
• Write your timeline that night, for your lawyer only, while the sequence is sharp.

Then call counsel, because the preservation letters described above have a clock on them.
