Liability for the Act or Fault of Another and for Things

Overview

A person injured by a child, an employee, a falling component, or an unsafe product must identify the rule connecting the defendant to the event. Art. 1457 CCQ recognises liability for another person and for things only in specified cases. Ownership, family ties, or employment therefore supplies a starting point, not a complete demonstration of liability.

The distinction between a presumption of fault (présomption de faute) and a presumption of liability (présomption de responsabilité) determines the defence. Parents and custodians of things can establish reasonable care. An employer cannot escape responsibility for an employee's qualifying fault merely by showing careful recruitment and supervision. Animal owners and owners of ruined immovables also face regimes that do not depend on their personal fault, once the necessary conditions are established.

These are principally extra-contractual liability (responsabilité extracontractuelle) rules. Where a valid contract governs the disputed obligation between the parties, art. 1458 CCQ prohibits choosing a more favourable regime. Each defendant's relationship with the victim must therefore be analysed separately.

Learning Objectives

• Identify the facts that trigger each regime and distinguish presumed fault, presumed liability, and fault that the victim must prove.
• Apply the rules governing authority, subordination, custody, animals, ruin, and product safety without confusing their defences.
• Analyse concurrent defendants, contractual relationships, and the evidence needed to establish or rebut liability.

Liability for Another Person

Parental authority and the minor's conduct

Under art. 1459 CCQ, the holder of parental authority (autorité parentale) must answer for injury caused by the minor's fault or qualifying act unless the holder proves freedom from fault in custody, supervision, and education. The claimant establishes minority, the defendant's authority, the child's relevant conduct, injury, and causation. The claimant need not separately prove defective parenting or its connection to the child's conduct before invoking the presumption.

A minor capable of discernment remains personally responsible for fault under art. 164 CCQ. If the minor lacks discernment, art. 1462 CCQ requires conduct that would otherwise have been considered faulty. An accident caused by an innocent movement does not automatically engage parental liability. Discernment depends on the child's actual understanding; there is no fixed civil-law age that conclusively resolves every case.

The defence addresses the parent's actual duties under art. 599 CCQ. Evidence of suitable rules, precautions concerning dangerous objects, responses to earlier incidents, and the example set by the parent is more useful than a general assertion that the child is well brought up. Supervision must be reasonable given age, temperament, surroundings, and foreseeable risks. Continuous observation of an adolescent is generally unrealistic, but knowledge of repeated dangerous conduct may require intervention.

Separation or divorce does not itself remove parental authority or the presumption. Actual custody and opportunities to supervise nevertheless matter to the defence. Delegation under art. 601 CCQ may establish adequate arrangements for supervision without erasing responsibility for earlier education or an imprudent choice of custodian. Majority and emancipation end parental authority; greater adolescent autonomy before those events affects the standard of care without creating an automatic exemption.

Art. 1459 CCQ separately addresses a person deprived of parental authority: liability depends on a connection between the minor's conduct and the education that person provided. The rule does not impose continuing physical supervision after deprivation.

Custodians, supervisors, and educators

Art. 1460 CCQ extends the parental model to a person entrusted, by delegation or otherwise, with a minor's custody, supervision, or education. Teachers, daycare operators, camp supervisors, and sports instructors may fall within it. The relationship can be express or implicit. The scope and duration of the undertaking determine the defendant's responsibilities.

The claimant proves the entrustment and the minor's causally relevant fault or qualifying act. The defendant then demonstrates supervision appropriate to the activity and children involved: staffing, instructions, equipment, enforcement of rules, and the unforeseeable nature of the particular conduct all matter. Reasonable care remains the standard. Losing custody normally ends the supervisory responsibility, although an earlier educational or organisational fault may still require analysis under the applicable rules.

The exception in art. 1460, para. 2 CCQ covers someone acting gratuitously or for a reward. The claimant must then prove ordinary fault. A reward can include pocket money received by an occasional teenage babysitter; the exception is not confined to wholly unpaid assistance. The character of the arrangement must be established rather than inferred from payment alone. This exception removes the presumption without conferring the gross-fault protection applicable to custody of certain adults.

Adults lacking discernment

Art. 1461 CCQ applies to a person who, as tutor, mandatary, or otherwise, assumes custody of an adult not endowed with reason. The claimant must prove custody, the adult's lack of discernment, a qualifying act under art. 1462 CCQ, injury, causation, and the custodian's gross fault (faute lourde) or intentional fault in exercising custody. Gross fault involves the serious carelessness, imprudence, or negligence described in art. 1474 CCQ.

A protection measure does not by itself establish lack of discernment for civil liability. Conversely, no prior judgment declaring incapacity is essential: the adult's condition can be proved after the event. The person's needs and the custodian's knowledge of foreseeable dangers inform the assessment of gross fault. Merely proving that more attentive supervision might have prevented an incident does not satisfy this heightened threshold.

Art. 1462 CCQ supplies a condition for liability for a person lacking reason; it creates no independent presumption against whoever is nearby. It also does not dispense with the employee's own fault required by art. 1463 CCQ.

Employers, functions, and mandate

Art. 1463 CCQ requires an employee's causal fault, a relationship of subordination (lien de préposition), and commission of that fault in the performance of the employee's functions. Once these conditions are proved, the employer (commettant) cannot rely on an absence of personal fault. The employer retains recourse against the employee (préposé), subject to the rules governing that recourse.

The power to direct and supervise the work is decisive. It need not be exercised continuously. Instructions about how tasks are performed, hiring and disciplinary powers, tools, schedules, and remuneration are evidentiary indicators. A written employment contract and payment are unnecessary, while a general right to inspect results may be insufficient. Control can pass to another person when labour is loaned, but the actual allocation of authority must be proved.

Performance of functions is a separate condition. In Dubé c. Havre des femmes Inc., [1998] R.J.Q. 346 (C.A.), the Court distinguished ordinary performance, abuse occurring within functions, and conduct merely occasioned by employment. Disobedience or criminality does not automatically remove an act from the employee's functions. Its purpose, connection to assigned tasks, and any benefit to the employer help determine whether it remains within them. Time and place are relevant without being conclusive.

Quebec decisions have sometimes considered factors drawn from common-law enterprise-risk analysis, particularly opportunities for abuse, entrusted power, and victim vulnerability. Those factors must remain tied to art. 1463 CCQ; they do not establish a separate automatic test that every wrong facilitated by employment satisfies. An employer's own negligent training or supervision may independently engage art. 1457 CCQ, even if the employee's act falls outside the functions.

For employees of the State or a public legal person, art. 1464 CCQ specifies that illegality, lack of authority, acting beyond competence, or acting as a peace officer does not alone terminate performance of functions. Any applicable statutory immunity must still be examined.

A mandate (mandat) concerns representation in juridical acts under art. 2130 CCQ and need not involve subordination. Art. 2164 CCQ makes the mandator answer for the mandatary's fault in performing the mandate. Where the mandatary is not an employee, the mandator may establish inability to prevent the injury. That defence distinguishes this situation from established liability under art. 1463 CCQ.

Worked example: childcare and dangerous objects

Factual Scenario

This example is hypothetical.

A child at a paid day camp finds a sharp tool in an unlocked equipment shed and throws it at a child passing on the adjacent public sidewalk. The injured child has no contractual connection to the camp. Assume the act would be faulty if the child possessed discernment.

Liability for Things and Animals

The autonomous act and custody

Art. 1465 CCQ requires injury caused by the autonomous act of a thing (fait autonome du bien) in the defendant's custody. The thing must play an active causal role through its own operation or movement. Bursting pipes, expanding roots, and a stationary cart whose brakes release can qualify. A passive icy surface on which someone slips ordinarily does not; a claim based on inadequate maintenance instead requires the appropriate fault analysis.

Human involvement must be assessed causally. A thing directly manoeuvred into the victim generally points toward personal fault. Earlier installation or merely pressing a machine's start button does not necessarily prevent its later malfunction from being autonomous. For a fire, identifying the burning premises is insufficient: the claimant must establish the probable autonomous act of a thing that caused the fire. Circumstantial evidence can establish that origin without identifying every technical detail of the failure.

The custodian of a thing (gardien d'un bien) has sufficient factual power of control, supervision, and direction to prevent injury. Ownership does not automatically establish custody. A lease, loan, or maintenance arrangement may reveal who controls the relevant operation. An employee handling equipment under the employer's general direction is usually not its independent custodian. Custody is generally alternative, although genuinely shared control can support multiple custodians. Because art. 1465 CCQ presumes fault, the individual custodian must be capable of discernment.

The custodian can rebut the presumption by proving reasonable prudence and diligence. General maintenance records should be connected to the actual event: inspections, warning signs, operating conditions, and the practical possibility of prevention. The fact that equipment had never failed before is insufficient by itself. Entrusting maintenance to a competent independent contractor may support the defence, but the custodian must still verify performance and respond to abnormalities.

Superior force (force majeure) under art. 1470 CCQ is another defence, requiring unforeseeability and irresistibility. Its burden is more demanding than proof of reasonable care. A third person's act invoked as superior force must have those characteristics; ordinary third-party negligence does not automatically discharge the custodian. The victim's causal fault can reduce recovery under art. 1478 CCQ and defeat it completely when it alone accounts for the injury.

Ruin of an immovable

Art. 1467 CCQ concerns the owner and the ruin of an immovable (ruine d'un immeuble), including partial ruin attributable to lack of repair or a construction defect. The claimant proves ownership, deterioration or disintegration, the prescribed cause, and resulting injury. A falling brick or collapsing permanent railing may qualify. Snow falling from a roof is not deterioration of the building itself. An elevator malfunction without physical breakage does not by itself prove ruin.

The construction defect or lack of repair is a condition to establish, sometimes through sufficiently persuasive factual presumptions. Ruin does not invariably prove its own cause. Ordinary use and the purpose of the affected component matter: a window screen is not necessarily defective because it cannot serve as a protective railing.

Once a causal construction defect or lack of repair is established, the owner's personal diligence or ignorance cannot defeat liability. Hiring someone else to build or maintain the premises does not transfer this risk away from the owner. Proof of good maintenance may rebut an allegation of lack of repair; it does not answer a proven construction defect. Superior force, including a qualifying external third-party act, and the victim's causal fault remain available. Recourse against the responsible contractor is a separate issue.

Art. 1467 CCQ preserves liability as custodian, so art. 1465 CCQ can also be pleaded when its conditions exist. In divided co-ownership, identify whether the failing component is private or common. The syndicate's responsibility for design or construction defects and lack of maintenance of common portions rests specifically on art. 1077 CCQ; describing the syndicate simply as their owner obscures that basis.

Animals and concurrent responsibility

Art. 1466 CCQ makes the owner responsible for injury caused by the animal even while it is in another person's custody, lost, or escaped. A person using the animal is also responsible during that use. The two liabilities are cumulative. Independent factual control can establish use, including without remuneration; briefly feeding someone else's animal does not necessarily do so.

The regime includes animals ordinarily considered wild when someone owns or controls them. A wild animal's mere presence on land does not make the landowner responsible under this provision. The animal must cause the injury: a sudden attack causing a person to fall while escaping can suffice without physical contact. A passive animal or an animal directly commanded to attack raises different questions about the relevant causal act and personal fault.

An owner or user cannot escape by proving careful training or supervision. Superior force and the victim's causal fault remain possible defences. The owner cannot invoke the user's negligence alone to avoid the cumulative responsibility that the provision creates. A third-party act relied on as superior force must be unforeseeable and irresistible.

Unsafe Products and Concurrent Claims

Safety defects and the persons responsible

Art. 1468 CCQ applies to a manufacturer, a distributor marketing the thing under its name or as its own, and professional suppliers, including wholesalers, retailers, and importers. Designers, assemblers, and component manufacturers may participate in the manufacturing process. An occasional private maker or seller, or a mere service provider who neither supplies nor markets the thing, does not automatically fall within this special regime.

Movables remain covered after incorporation into an immovable or placement there for its service or operation. Under art. 1469 CCQ, the safety defect (défaut de sécurité) is assessed against the safety normally expected in all the circumstances. The statutory examples include design, manufacture, preservation, presentation, and insufficient instructions about dangers or precautions. A product may work as designed yet lack adequate safety warnings.

The victim proves the defect, injury, and their causal connection, without having to identify a particular manufacturing fault. Ordinary use, expected user knowledge, concealed dangers, and applicable safety standards inform the assessment. Regulatory compliance is relevant but does not conclusively establish safety.

In Imperial Tobacco Canada ltée c. Conseil québécois sur le tabac et la santé, 2019 QCCA 358, the Quebec Court of Appeal explained the significance of sufficient, accurate risk information. General warnings may be inadequate for serious or concealed dangers. The Court also treated the specific safety-defect regime as governing the alleged defect: a defence successfully established within it cannot be circumvented merely by relabelling that same defect as general fault under art. 1457 CCQ.

Knowledge, development risks, and warnings

Art. 1473, para. 1 CCQ allows proof that the victim knew or could have known the defect, or could have foreseen the injury. Imperial Tobacco requires meaningful knowledge of the specific danger, associated risk, and available protective measures. General awareness that a product is dangerous does not necessarily suffice. The court must also distinguish informed risk-taking from renunciation of recourse under art. 1477 CCQ. Causal victim fault may support apportionment under art. 1478 CCQ, but a manufacturer cannot casually shift its own failure to inform onto the consumer.

The development-risk defence in art. 1473, para. 2 CCQ requires proof that the defect could not have been known given the state of knowledge when the thing was manufactured, distributed, or supplied. Subjective ignorance is insufficient. The relevant scientific and technical knowledge is assessed objectively.

The defendant must also have fulfilled its duty to inform when it later learned of the defect. Evidence should distinguish what science could reveal at market entry from what the defendant subsequently knew and communicated. Superior force remains available, but a manufacturer cannot ordinarily treat a supplier's failure to transmit warnings as an unrelated third-party event relieving every participant of responsibility.

Contracts, solidarity, and the delivery-cart example

Between direct contracting parties, a claim arising from the contractual obligation must respect art. 1458 CCQ. Warranty rights transmitted with property under art. 1442 CCQ differ from the purchaser's direct warranty remedy against manufacturers and intermediaries under art. 1730 CCQ. General Motors Products of Canada Ltd. c. Kravitz, [1979] 1 R.C.S. 790, concerns the earlier development of accessory transmission.

Imperial Tobacco allowed reliance on the extra-contractual safety-defect regime despite a direct remedy under the Consumer Protection Act. That result should not become an unqualified statement that every sub-purchaser can always choose either regime: the position of rights arising under art. 1442 CCQ or art. 1730 CCQ requires separate analysis.

Solidarity (solidarité) also needs a legal basis. Art. 1526 CCQ concerns extra-contractual injury caused by the faults of two or more persons. Multiple defendants, including parents or an employer and employee, do not automatically establish its conditions. Depending on the applicable rules, concurrent obligations may instead be in solidum. Art. 1480 CCQ addresses causal uncertainty involving a collective wrongful act or separate faults each capable of causing the injury. Art. 1481 CCQ concerns equal redistribution of the share of a person expressly exempted by a special statute. Neither provision generally makes every person connected to an accident liable.

Factual Scenario

This example is hypothetical.

Suppose a delivery employee correctly brakes a cart, then leaves it while making the delivery. An internal valve fails and the unattended cart rolls into a neighbour's display. The delivery company purchased the cart directly from its manufacturer.

Practice Checklist

• Identify the victim's contractual relationship with each defendant and the precise obligation in dispute.
• Prove the triggering facts before relying on any presumption: authority, entrustment, subordination, custody, ownership, qualifying act, ruin, or safety defect.
• For minors and adults lacking reason, analyse discernment and the conduct required by art. 1462 CCQ; identify any reward exception or gross-fault threshold.
• Distinguish employee fault within functions from the employer's own fault and from a mandatary's conduct.
• Connect maintenance and supervision records to the particular event; distinguish reasonable care from superior force.
• For ruin, prove the construction defect or lack of repair; for animals, consider owner and user together.
• Preserve product evidence, warnings, scientific knowledge, and the chronology of later notices.
• Establish each concurrent defendant's legal basis, possible victim fault, contribution claims, and the prohibition against duplicate compensation.
