Liability for Acts or Faults of Others and for Things

Overview

Quebec civil law recognizes that a person may be liable not only for their own fault (faute) but, in specific settings, for the act or fault of another and for harm caused by property. These regimes sit within extra-contractual liability (responsabilité civile) and reflect policy choices about prevention and loss allocation. This lesson explains the core Civil Code of Québec provisions that structure (1) liability for another: parents, custodians and educators of minors, tutors and de facto custodians of adults not endowed with reason, and employers for their employees and (2) liability for property: the custodian of a thing, the owner for the ruin of their immovable, the owner or guardian of an animal, and product liability for manufacturers, distributors, and suppliers.

Learning Objectives

• Distinguish the main presumptions and defence structures under ss. 1459, 1460, 1461, 1463, 1465–1467, and 1468–1473 CCQ.
• Apply the tests for parental liability and the specific defence of absence of fault in custody, surveillance, and education.
• Identify when delegation triggers the custodian/supervisor/educator regime and how gratuitous care shifts the standard from presumption to fault proven.
• Evaluate vicarious liability of the employer (commettant) for the employee, including “within the exercise of functions” and the relationship of subordination.
• Analyze property-based presumptions: autonomous act of a thing, ruin of an immovable, and strict liability for animals.
• Work through product liability based on a safety defect, including defences such as that of an insufficient state of knowledge, knowledge by the user, and ongoing duties to warn.

Key Concepts & Definitions

• Extra-contractual liability (responsabilité civile): liability to repair injury caused outside a contract (s. 1457 CCQ).
• Fault (faute): failure to respect required conduct, assessed contextually (s. 1457 CCQ).
• Causation (lien de causalité): the factual and legal connection between fault (or fact) and the injury.
• Injury/damage (préjudice): bodily, moral, or material injury (s. 1457 CCQ).
• Custodian (gardien): person with use, direction, surveillance, or control over a thing.
• Ruin (ruine): total or partial disintegration/collapse of an immovable or a constituent part.
• Employer (commettant) and employee (préposé): the party exercising authority and the subordinate whose fault engages s. 1463 CCQ.
• Gross fault (faute lourde) / intentional fault (faute intentionnelle): higher thresholds of misconduct (s. 1474 CCQ).
• Safety defect (défaut de sécurité): a condition where the product falls short of the safety one is normally entitled to expect (s. 1469 CCQ).

Introduction

1) Liability for the Act or Fault of Another (s. 1457, para 3 CCQ)

He is also bound, in certain cases, to make reparation for injury caused to another by the act, omission or fault of another person or by the act of things in his custody.

The Code contemplates liability for others “in certain cases.” Those cases are set out chiefly in ss. 1459, 1460, 1461, and 1463 CCQ. The historical “control” language has receded from the text, but functional proxies for authority and supervision remain central.

A. Holders of Parental Authority (s. 1459 CCQ)

A person having parental authority is bound to make reparation for injury caused to another by the act, omission or fault of a minor under his authority, unless he proves that he himself did not commit any fault with regard to the custody, supervision or education of the minor.
A person deprived of parental authority is bound in the same manner, if the act, omission or fault of the minor is related to the education he has given to him.

What it is: A presumption of parental fault where a minor’s fault or action that would have been a fault, but for lack of discernment (s. 1462 CCQ), causes injury. The presumption rests on an implicit failure in custody, surveillance, or education.

Elements to trigger the presumption

1. Filiation/authority: proof that the defendant is a holder of parental authority (autorité parentale) (see ss. 599–612, 600, 607 CCQ).
2. Minor: proof of minority (s. 153 CCQ).
3. Fault or injurious act of the child: either a fault (for a child endowed with reason) or an injurious act which, absent the child’s incapacity of discernment, would constitute a fault (s. 1462 CCQ).
4. Causation and injury.

Scope and limits

• The term “another” refers to a member of the author's family.
• The presumption extends to the child’s injurious act via s. 1462 CCQ, thereby avoiding true strict liability for very young children while enabling claims against parents.
• Solidarity between parents is not presumed (s. 1525 CCQ). Naming both parents is prudent given joint exercise of parental authority (s. 600 CCQ).

Defence: Absence of fault in custody, surveillance, and education Parents must prove on a balance of probabilities that they were not at fault in all three dimensions, adapted to the child’s age, temperament, and context:

• Custody/surveillance: greater vigilance for preschoolers; not an obligation of result but of means; tolerating dangerous objects or obviously risky situations weighs against parents.
• Education: demonstration of consistent moral guidance, reinforcement by example, clear household rules, school records and testimony about behaviour, etc.
• Causation nuance: where a parent has been deprived of actual ability to monitor (e.g., by circumstances), it may be easier to rebut the presumption.

Minors 14+ and autonomy CCQ increases autonomy for minors 14–18 in personal and patrimonial spheres (e.g., health care consent at 14, s. 17 CCQ; employment acts, s. 156 CCQ; emancipation, ss. 167–175 CCQ). Courts have been reluctant to condemn parents of “almost-majors.” Expect the presumption’s practical weight to diminish as autonomy rises, though it endures until majority (s. 153 CCQ). Emancipation ends the presumption; majority ends it regardless of lingering factual influence.

Example A 15-year-old with a history of impulsivity injures a classmate by misusing a metal tool at home. Parents show established rules for tool use, prior coaching, storage in a locked cabinet, and that the teen defeated the lock to “experiment.” With school records of good conduct and testimony from a coach, the parents may rebut the presumption.

B. Custodians, Supervisors, and Educators by Delegation (s. 1460 CCQ)

What it is: A presumption of fault against a custodian, supervisor, or educator who, by delegation or otherwise (s. 601 CCQ allows delegation of authority), is charged with a minor and the minor’s fault or qualifying injurious act.

Conditions

1. Minor and the child’s fault/injurious act within s. 1462 CCQ.
2. Delegation (express or tacit) of parental authority or a function akin to it (custody, supervision, education).
3. Causation and injury.

Defence structure Two coordinated showings are typical:

• General organization: adequate rules, ratios, safety measures, discipline policies suited to the activity and age.
• Unpredictability: despite those measures, the specific injury was not reasonably foreseeable.

No higher standard than parents Courts do not demand more from delegated custodians than from parents in equivalent contexts.

Special rule for gratuitous care (s. 1460(2) CCQ) If the person acts gratuitously or for a “reward” (small compensation or in-kind), the presumption falls away; liability reverts to fault proven under s. 1457 CCQ. Practically, the same factors will be weighed, but the burden sits with the plaintiff.

Example Volunteer soccer parents implement a sign-in/out protocol, cones to define play zones, and age-appropriate drills. An unforeseen scuffle leads to a broken tooth. With clear evidence of organization and the unpredictable nature of the scuffle, the volunteers defeat liability under s. 1460(2) unless a specific preventable risk was ignored.

C. Tutor and De Facto Custodian of a Major Not Endowed with Reason (s. 1461 CCQ)

What it is: For tutors and de facto custodians of an adult not endowed with reason, liability requires gross fault or intentional fault in the exercise of custody; plus, the adult’s act must qualify under s. 1462 CCQ (i.e., would have been a fault if endowed with reason).

Obligations and context

• Tutorship to a person of full age is structured (ss. 256–297 CCQ). The tutorship judgment (scope of incapacity) frames expectations (s. 288 CCQ).
• Delegation of physical custody is possible (s. 260 CCQ), including to institutions; cumulative exposures may arise between legal and factual custodians.

Standard to attract liability

• Gross fault: insouciance, imprudence, or gross negligence (s. 1474 CCQ).
• Intentional fault: conduct with knowledge it will cause injury.

Example A tutor knowingly allows an adult under tutorship, with a documented pattern of wandering into traffic, to leave unaccompanied after disabling door alarms; the adult causes a collision. This is susceptible to a finding of gross fault.

D. Employer (Commettant) for the employee (s. 1463 CCQ)

What it is: An objective liability regime: the employer must guarantee third parties against injury caused by the employee’s fault committed in the exercise of functions. Absence of employer fault is not a defence. The employer may seek recourse against the employee.

What must be shown

1. Fault of the employee (under s. 1457 CCQ or a more favourable regime).
2. Relationship of subordination (lien de préposition): authority to set objectives and, typically, to direct and supervise methods. Degrees vary with specialization, but immediate, direct authority is key. Ownership of tools, flexible hours, or off-site work are relevant but not decisive. The link can migrate with effective control (e.g., temporary secondment).
3. Within the exercise of functions: ask whether the conduct, despite disobedience, crime, or off-hours/ off-site features, was ultimately in the employer’s interest or a fault of competence in performing assigned tasks. If the employment merely created the occasion for a purely personal frolic, the regime does not apply.

Limits and nuances

• Third-party fault or force majeure can break causation (ss. 1478, 1470 CCQ).
• Solidarity between employer and employee is not automatic; it may arise where the employer has a distinct personal fault (e.g., lax supervision, poor training) (s. 1526 CCQ).
• Intentional, even criminal acts can fall within functions depending on authority, opportunity, and employer-created risk; courts evaluate factors such as the occasion to abuse power, proximity to the employer’s aims, institutional context, authority over the victim, and victim vulnerability.
• Punitive damages normally attach to the employee alone, save exceptional circumstances.

Example A night guard intentionally sets a small blaze to showcase responsiveness, causing major loss. Given the role and risk profile, a court may treat the act as committed in the exercise of functions, engaging employer liability, even though the act was intentional.

2) Liability for the Fact of Property (ss. 1465–1467, 1466 CCQ)

Quebec separates three major strands: (1) the custodian of a thing (presumption of fault), (2) the owner for ruin of an immovable (strict and difficult to rebut), and (3) animals (strict liability for owner and guardian). A fourth, conceptually distinct regime governs product safety defects (ss. 1468–1473 CCQ).

A. The Custodian of a Thing (s. 1465 CCQ)

What it is: A presumption of fault where the autonomous act of a thing causes injury.

Two proofs for the plaintiff

1. Autonomous act of a thing: harm caused by the dynamism of the object itself without direct human intervention at the moment. Simply being present is not enough; pressing a start button does not defeat autonomy. Inert things can act through physics (gravity, pressure).
2. Custodian: the person with use, direction, surveillance, control, but not necessarily the owner. Municipal networks, tenants, or users may be custodians depending on factual control and contractual allocation.

Defences

• No fault: show reasonable maintenance, appropriate safety measures, timely repairs, and that a reasonable person could not have prevented the incident in context.
• Force majeure (s. 1470 CCQ).
• Fault of the victim or third party (s. 1478 CCQ).

Example A buried water main bursts spontaneously. The municipality proves a prudent maintenance program, inspections, and no warning signs. Absent contrary proof, it may rebut the presumption by establishing no fault.

B. Ruin of Immovables (s. 1467 CCQ)

What it is: A strict presumption against the owner where injury results from the ruin of an immovable (or a constituent part), typically due to construction defect or lack of maintenance.

Key features

• Applies to partial or total disintegration involving a true component of the building (e.g., brick, balustrade, staircase, elevator, chimney mortar, conduit), not to incidental items placed on it.
• Cumulation: s. 1467 can cumulate with s. 1465 if the owner is also custodian.
• Condo contexts: determine whether the failing element is common or privative to identify the liable owner/syndicate.

Defences are narrow

• Force majeure, fault of the victim, or third party.
• General good maintenance is not sufficient; once ruin is shown, the presumption is near-absolute.
• Contractual clauses may limit duties inter partes for material damage, but never for bodily injury (s. 1474(2) CCQ) and not against third parties.

Example A façade brick detaches and injures a passer-by. The owner cannot defeat liability by showing a recent cleaning; absent force majeure or victim/third-party fault, responsibility follows.

C. Animals (s. 1466 CCQ)

What it is: The Code imposes strict liability on both the owner and the guardian of an animal for injury caused by the animal, including when it has escaped. This is the clearest strict liability case in the CCQ.

Scope and parties

• Captures domestic animals over which a person can exercise control. Res nullius (wild animals not owned) do not engage s. 1466.
• “Guardian” is read broadly to include non-owner users with factual control (think of a person who rents a horse). Owner liability persists even where a third party is using the animal.

Defences

• Force majeure or fault of the victim; there is no “no-fault” defence.
• No contact is needed; swerving to avoid an escaped animal may suffice if causation is proved.

Example A horse escapes a paddock due to an unlocked gate and causes a pileup. The owner and the trainer exercising control that day will face strict liability, subject only to force majeure or victim fault.

D. Product Liability: Manufacturer, Distributor, Supplier (ss. 1468, 1469, 1473 CCQ)

What it is: An objective regime protecting third parties injured by a safety defect in a movable (including components incorporated into immovables). It sits alongside, but separate from, contractual remedies and the Consumer Protection Act (L.p.c.).

Who is exposed

• Manufacturer: designers, assemblers, fabricators, including component makers.
• Suppliers/Distributors: professional intermediaries who put the product on the market (s. 1468(2) CCQ). “Simple brokers” and non-professional private sellers fall out.

What is a “safety defect” (s. 1469 CCQ)

• The product does not afford the safety one is normally entitled to expect given its normal use and the profile of expected users (including children where applicable).
• Examples include design defects, manufacturing defects, poor preservation or presentation, and insufficient warnings of inherent dangers or means of self-protection.

Plaintiff’s burden

• Prove defect, injury, and causation. All types of injury are compensable (bodily, moral, material). Limitation runs 3 years from manifestation of the injury (ss. 2925–2926 CCQ).

Defences

• General: force majeure; fault of the victim with apportionment (ss. 1470, 1478 CCQ).
• Knowledge defence: the user knew or could have known of the defect (s. 1473(1) CCQ), assessed contextually and consistent with apportionment principles.
• State-of-the-art (innovations): the defect could not be known given the state of knowledge at fabrication/distribution (s. 1473(2) CCQ). This is objective, not subjective.
• Ongoing duty to warn: once the manufacturer or supplier learns of a safety defect, they must inform users; failure defeats reliance on the innovations defence.

Contract/consumer law interface

• Between contracting parties, s. 1458(2) CCQ channels claims into contractual regimes (e.g., warranty of quality, ss. 1726–1731 CCQ; L.p.c., incl. s. 53 for direct actions).
• A sub-acquirer or statutory consumer may have direct recourse under those regimes; otherwise, third parties proceed under ss. 1468–1473 CCQ.

Example A window system incorporated into a building shatters without impact because of an internal stress defect. Injured passers-by invoke ss. 1468–1469 against the component maker and distributor. The defendants must establish either state-of-the-art at the time or other recognized defences; they must also warn once the defect becomes known.

Practice Checklist

Parents (s. 1459)

• Prove filiation/authority; minority; child’s fault or qualifying injurious act; injury and causation.
• For defence, assemble evidence of custody, surveillance, education: rules, prior incidents and responses, school reports, third-party testimony.
• Adjust the defence to child’s age and autonomy; consider emancipation or de facto limits to parental control.

Delegates (s. 1460)

• Establish the delegation (written or by conduct) and the role (custodian/supervisor/educator).
• Document general organization and specific unpredictability.
• If acting gratuitously or for a reward, frame the case under s. 1460(2) and focus on the plaintiff’s proof of fault.

Tutor/de facto custodian of adult (s. 1461)

• Obtain and review tutorship judgment and incapacity scope.
• Test facts against gross fault or intentional fault.
• Track any delegation to institutions (possible cumulative exposures).

Employer (s. 1463)

• Confirm employee fault; articulate relationship of subordination with concrete indicators of control.
• Analyze “within functions” by purpose and risk, not merely by time/place/obedience.
• Consider whether a distinct employer fault exists (training, supervision).
• Evaluate third-party fault / force majeure; consider punitive-damage exposure primarily for the employee.

Custodian of a thing (s. 1465)

• Prove autonomous act and identify the custodian factually.
• For defence, build a record of maintenance, policies, and impossibility to prevent in context.

Ruin of immovables (s. 1467)

• Show ruin of a component; link to injury.
• Identify the owner (and in condo, common vs. privative).
• Anticipate that good maintenance alone will not rebut; test force majeure or victim/third-party fault only.

Animals (s. 1466)

• Plead owner and guardian in the alternative if needed; strict liability applies.
• Assess force majeure and any victim provocation or disregard of known risks.

Products (ss. 1468–1473)

• Identify manufacturer and professional suppliers.
• Prove safety defect, injury, causation; gather evidence on warnings and presentation.
• Anticipate state-of-the-art and user knowledge defences; probe post-market duty to warn.
• Respect contractual channelling under s. 1458(2) where applicable; consider L.p.c. routes for consumers.
