Can You Sue a Bar After an Assault in Ontario?

Yes. A bar or nightclub can be sued after an assault when the establishment’s own conduct caused or contributed to the injury.

A claim can arise if staff continued serving an apparently intoxicated and aggressive patron, ignored a confrontation that was escalating, used an unsafe ejection procedure or permitted security personnel to use unnecessary force. The individual attacker may remain primarily responsible, but responsibility does not always end with the person who delivered the blow.

Our Ontario assault injury lawyers investigate whether a bar, nightclub, restaurant, event venue, property occupier or security company shares legal responsibility for a serious assault.

A Bar Is Not Responsible for Every Assault on Its Property

Just because an assault occurs inside a bar does not establish negligence by the establishment. Some attacks happen suddenly, without threats, visible hostility or any reasonable opportunity for staff to intervene. A bar is not expected to guarantee that no patron will ever become violent.

The analysis changes if there were warning signs before the attack. Employees may have watched an argument continue, received complaints about threatening conduct, intervened in an earlier confrontation or seen a patron become increasingly intoxicated and aggressive.

The central questions are:

• What did the establishment know, or what should it reasonably have known?

• Was there a foreseeable risk that someone would be injured?

• Did staff have a reasonable opportunity to reduce that risk?

• Did the establishment’s response contribute to what happened?

The law does not judge the bar solely with the benefit of hindsight. The focus is on the information available before the assault and the precautions that were reasonably available at that time.

The Occupiers’ Liability Act Applies to Activities at a Bar

Section 3 of Ontario’s Occupiers’ Liability Act requires an occupier to take reasonable care in the circumstances to see that people entering the premises are reasonably safe.

That duty is not confined to physical hazards such as broken stairs or spilled drinks. The Act expressly states that the duty can apply where a danger is caused by an activity carried on at the premises.

In a bar or nightclub, the relevant activities may include alcohol service, crowd management, security arrangements and the response to a confrontation between patrons.

What amounts to reasonable care depends on the circumstances. A crowded nightclub holding a large event may require different precautions from a small restaurant on a quiet evening. The presence of bouncers does not, by itself, prove that reasonable care was taken, while the absence of a large security team does not necessarily prove negligence.

Successful casesmust identify what the establishment should reasonably have done differently and how that failure contributed to the assault.

Can a Bar Be Liable for Overserving Someone Who Later Attacks Another Patron?

Yes. Ontario law specifically addresses the sale of alcohol to intoxicated people and the injuries they may cause.

Section 32 of the Liquor Licence and Control Act, 2019 prohibits selling or supplying liquor, or permitting liquor to be sold or supplied, to a person who is or appears to be intoxicated.

Section 52 goes further by addressing civil liability. It applies where liquor is sold to someone whose condition is such that further consumption would apparently intoxicate the person, or increase the person’s intoxication, to the point that the person would be in danger of causing injury. If that person then injures someone else while intoxicated, section 52 provides a right to recover compensation from the person who sold the liquor, subject to the statutory requirements and the evidence in the case.

Claims against businesses that sell or supply alcohol are often described as commercial host liability claims.

The Supreme Court of Canada considered the duty of a licensed establishment in Jordan House Ltd. v. Menow. The tavern knew that the patron had a history of becoming intoxicated, continued serving him and then ejected him into circumstances that exposed him to a foreseeable danger.

In Stewart v. Pettie, the Supreme Court confirmed that the duty of a commercial host can extend to people injured by an intoxicated patron. The restaurant was not liable on the facts of that case because the evidence did not establish that it should reasonably have foreseen that the intoxicated patron would drive.

How Can You Prove That a Bar Overserved the Attacker?

An injured person will rarely know exactly what the attacker drank or what employees observed throughout the evening. That history usually has to be reconstructed from several sources.

Point-of-sale records and itemized tabs can show what was ordered, when it was ordered and which server processed the transaction. Debit and credit card records may provide additional information, although they will not identify drinks purchased by other patrons or alcohol consumed before arrival.

Surveillance footage can show the patron’s balance, coordination, interactions and behaviour. It may also reveal that bartenders, servers or security personnel had already warned, monitored or removed the patron before the assault.

Witnesses may recall slurred speech, stumbling, shouting, threats or attempts to provoke a fight. An incident report or security log may establish that employees had become involved earlier in the evening.

Can a Bar Be Liable for Ignoring an Escalating Confrontation?

A bar may potentially be liable even where overservice is not established. Employees might become aware of a danger because they observe an argument, receive complaints about threats, intervene in a confrontation or learn that one patron is waiting to attack another. Once a serious risk is apparent, the establishment must decide how to respond.

Depending on the circumstances, reasonable steps could include separating the patrons, refusing further service, increasing supervision, calling police or arranging for the people involved to leave at different times or through different exits.

A negligent-security claim should be more specific than an allegation that the venue should have employed additional bouncers. The evidence should identify what staff knew, what response was reasonably available and how the omitted precaution contributed to the injury.

Can You Sue If the Assault Happened Outside the Bar?

Possibly. A claim against a bar does not necessarily end at the front door.

An assault may occur on a patio, near an entrance, on a sidewalk or in an adjacent parking lot after the confrontation began inside. The location is relevant, particularly when determining whether the establishment controlled the area, but it is not the only consideration.

One recurring issue is the manner in which patrons are removed. Staff may know that two people have threatened each other but eject them through the same door within moments of one another. Security personnel may also know that an aggressive patron is waiting outside and nevertheless direct the intended victim into the same area.

An establishment’s exposure may be greater where the outside assault was a foreseeable continuation of a confrontation that staff had already observed or attempted to manage.

Different considerations arise where the patrons left separately and the attack occurred later in a place the bar did not own or control. The entire sequence must be examined rather than assuming that every parking-lot assault is—or is not—the bar’s responsibility.

Can You Sue a Bouncer for Using Excessive Force?

A bar may remove patrons in appropriate circumstances, but staff and security personnel cannot use unlimited force. Section 44 of the Liquor Licence and Control Act, 2019 applies where a licensee reasonably believes that a person is unlawfully on the premises, present for an unlawful purpose or contravening the law. If the person refuses to leave, the section permits removal using no more force than is necessary.

Whether section 44 applies and whether the force was necessary will depend on the circumstances. A civil claim may arise where a bouncer punches, kicks or tackles someone without justification, applies a dangerous restraint or continues using force after the person is under control.

Relevant evidence may include:

• whether the patron was resisting;

• whether anyone had a weapon;

• the number of security personnel involved;

• whether warnings or instructions were given;

• the type and duration of the restraint; and

• what happened after the patron was subdued.

The potential defendants may include the individual guard, the company employing the guard and the establishment. A bar does not necessarily avoid responsibility simply because it contracted security services to another company.

Video evidence is often particularly important in these cases because witness accounts of a chaotic confrontation can differ sharply.

What Evidence Should Be Preserved After a Bar or Nightclub Assault?

Surveillance footage is often the most urgent evidence because some recording systems overwrite existing footage after a relatively short period.

A preservation request should not be limited to the moment of impact. The most useful footage may show the attacker being served, an earlier argument, intervention by security personnel or the timing of an ejection.

The request may need to cover cameras recording:

• the bar and service areas;

• entrances and exits;

• hallways and stairwells;

• the dance floor;

• patios;

• sidewalks near the entrance; and

• parking areas.

Neighbouring businesses may also have exterior cameras that captured an assault outside.

Foster Injury Law’s Experience in a Bar-Assault Case

In Pastink et al. v. 1190393 Ontario Limited et al., 2023 ONSC 6037, I represented a plaintiff who suffered a serious brain injury after an assault

outside a bar.

The lawsuit named the alleged assailant and the establishment. The claim against the bar included allegations concerning the alcohol served to the alleged assailant before the attack.

The bar brought a summary judgment motion seeking dismissal of the plaintiffs’ claim against it before trial. The alleged assailant had also advanced a crossclaim against the bar based on overlapping allegations, but the bar did not ask the Court to dismiss that crossclaim.

Justice Fowler Byrne dismissed the motion. Granting the requested partial summary judgment would have left the overlapping issues to be determined through the surviving crossclaim, creating a risk of duplicative proceedings and inconsistent factual findings.

Our firm represents people who have sustained serious brain injuries in assaults and other incidents.

Who May Be Sued After a Bar or Nightclub Assault?

The name that is displayed outside a venue is not always the legal name of the company operating it. The property owner, licensed operator, management company, event organizer and security contractor may be separate entities.

Depending on the evidence, a lawsuit may name:

• the person who committed the assault;

• the corporation operating the bar or nightclub;

• an owner or occupier of the premises;

• a security company; and

• the security personnel directly involved.

Identifying the correct defendants can also affect whether compensation can realistically be recovered. An individual assailant may have limited assets, and insurance policies commonly exclude intentional conduct by the insured. A commercial liability policy may respond to negligence allegations against a bar, occupier or security company, depending on the policy and the facts.

The existence of insurance does not create liability, but it can affect whether a valid judgment or settlement can be paid.

How Long Do You Have to Sue a Bar in Ontario?

Under Ontario’s Limitations Act, 2002, the basic limitation period is generally two years from the date the claim was discovered.

A lawsuit may include an intentional assault claim against the attacker and separate negligence claims against a bar, occupier or security company. An exception that affects the limitation period for one claim or defendant does not necessarily preserve the claims against every commercial defendant.

An injured person should not wait for the criminal proceeding to conclude before investigating the bar’s role. Criminal proceedings do not automatically stop the civil limitation period from running, and they do not prevent surveillance footage or business records from being overwritten or destroyed.

Frequently Asked Questions About Bar-Assault Claims

Is a bar liable whenever an intoxicated patron starts a fight?

No. The evidence must connect the bar’s conduct to the injury. Relevant issues include whether the patron appeared intoxicated, whether the bar continued serving alcohol, whether staff observed aggressive behaviour and whether the assault was reasonably foreseeable.

Can a nightclub be liable even if overservice cannot be proven?

Yes, cases can arise from ignored threats, inadequate security, unsafe ejection procedures or excessive force used by security personnel.

Can a bar be liable for an assault in its parking lot?

Possibly. The analysis will include who controlled the parking lot, what occurred inside the establishment, how the patrons came to be outside and whether the attack was a foreseeable continuation of the earlier confrontation.

Can I sue after being injured by a bouncer?

A claim may be available where the bouncer used more force than was reasonably necessary. The individual guard, security company and establishment may all require investigation.

Does a bar have to give me its surveillance footage?

The establishment may not provide footage voluntarily merely because it is requested. A preservation letter could demand that relevant recordings not be destroyed, and the footage may later be obtained through the litigation process.

Should I wait for the criminal case before contacting a civil lawyer?

No. Evidence which is relevant to the bar’s responsibility may disappear while the criminal proceeding is ongoing, and the limitation period against the commercial defendants may continue to run.

Lawsuits against bars or nightclubs require so much more than proof that an assault occurred. The investigation must reconstruct what employees observed, what alcohol was served, how the conflict developed, what security personnel did and how the parties came to be in the location where the attack occurred.
