Liability for Acts or Faults of Others and for Things

Overview

Quebec civil law imposes liability for a person's own fault (faute), but also, in defined circumstances set out in the Civil Code of Quebec (CCQ), for injury caused by the act or fault of another person or by the act of a thing. Art. 1457, para. 3 CCQ lays down the principle: a person is bound, "in certain cases," to make reparation for injury caused by the act or fault of another or by the act of things in that person's custody. Each of these "certain cases" is governed by separate provisions that differ in the nature of the presumption, the burden of proof, and the available means of exoneration.

Three subdivisions structure the subject. The first concerns liability for the act or fault of another (arts. 1459, 1460, 1461, 1463 CCQ). The second addresses liability for things (arts. 1465, 1466, 1467 CCQ). The third governs liability of the manufacturer (fabricant), distributor (distributeur), and supplier (fournisseur) for a safety defect (defaut de securite) in a product (arts. 1468, 1469, 1473 CCQ). For each regime, it is necessary to distinguish the conditions of application, the presumptions at play, and the defences available.

Learning Objectives

Distinguish the presumption of fault against holders of parental authority (autorite parentale) under art. 1459 CCQ from the irrebuttable presumption binding the employer (commettant) under art. 1463 CCQ, and explain why the available means of exoneration differ.
Apply the conditions of liability of custodians, supervisors, and educators by delegation under art. 1460 CCQ, including the exception for gratuitous custodians.
Demonstrate the role of art. 1462 CCQ as a mechanism for engaging the special regimes when the person who caused the injury lacks discernment.
Identify the constitutive elements of the relationship of subordination (lien de preposition) and the purpose test (test de finalite) used to determine whether the fault was committed within the scope of the employee's functions.
Analyse the concept of the autonomous act of a thing (fait autonome du bien) and identify the custodian within the meaning of art. 1465 CCQ.
Compare the rebuttable presumption against the custodian of a thing with the near-absolute presumption against the owner of an immovable whose ruin causes injury (art. 1467 CCQ).
Evaluate the no-fault regime for animals (art. 1466 CCQ) and its narrow defences.
Apply the extra-contractual product-liability regime (arts. 1468, 1469, 1473 CCQ), distinguish the categories of safety defect, and master the defences based on the state of knowledge and user knowledge.

Key Concepts and Definitions

Extra-contractual liability (responsabilite civile extracontractuelle): the obligation to make reparation for injury caused outside a contract (art. 1457 CCQ).
Fault (faute): failure to respect the standard of conduct required by the circumstances, usages, or law (art. 1457 CCQ).
Injury (prejudice): bodily, moral, or material harm suffered by the victim (art. 1457 CCQ).
Causation (lien de causalite): the factual and legal connection between the fault (or qualifying act) and the injury sustained.
Custodian of a thing (gardien d'un bien): the person exercising the use, direction, surveillance, and control of a thing; a factual concept independent of ownership.
Ruin of an immovable (ruine d'un immeuble): total or partial disintegration of an immovable or a constituent element thereof.
Employer (commettant): the person exercising a power of direction and control over an employee (art. 1463 CCQ).
Employee (prepose): the subordinate whose fault may engage the liability of the employer (art. 1463 CCQ).
Relationship of subordination (lien de preposition): the power of the employer to direct and control the employee's work.
Gross fault (faute lourde): recklessness, imprudence, or gross negligence (art. 1474 CCQ).
Intentional fault (faute intentionnelle): conduct undertaken with knowledge that it will cause injury.
Safety defect (defaut de securite): a condition where a product does not afford the safety one is normally entitled to expect (art. 1469 CCQ).

Liability for the Act or Fault of Another

Art. 1457, para. 3 CCQ recognises that a person may, in certain cases, be bound to make reparation for injury caused by the act or fault of another. Each regime rests on some form of authority, custody, or economic relationship between the defendant and the person whose conduct caused the injury.

The regimes differ in the nature of the presumption and in the scope of exoneration. Parents and delegated custodians bear a rebuttable presumption of fault. Tutors (tuteurs) and de facto custodians of incapacitated adults are liable only for gross or intentional fault. The employer bears an irrebuttable presumption of liability.

Holders of Parental Authority (art. 1459 CCQ)

Art. 1459 CCQ provides that the holder of parental authority is bound to make reparation for injury caused to another by the act or fault of a minor under that authority, unless the holder proves that no fault was committed in the custody, supervision, or education of the minor. A person deprived of parental authority is bound in the same manner if the act or fault of the minor is related to the education that person gave the child (art. 1459, para. 2 CCQ).

Nature of the presumption. Art. 1459 CCQ establishes a simple (rebuttable) presumption of fault against every holder of parental authority when a minor causes injury. The holder may rebut it.

Conditions of application. Four elements must be met:

The defendant holds parental authority over the child, whether by filiation (art. 599 CCQ) or by court order (art. 607 CCQ). Both parents exercise this authority jointly (art. 600 CCQ), even after separation or divorce (arts. 513, 521, 521.18 CCQ).
The child is a minor, that is, under 18 years of age (art. 153 CCQ).
The child committed a fault (if endowed with reason) or an injurious act that would have constituted a fault if the child had been endowed with reason (art. 1462 CCQ).
Injury and causation are established.

Solidarity between parents. Solidarity (solidarite) is not presumed (art. 1525 CCQ), and art. 1459 does not expressly provide for it. Given that parental authority is exercised jointly, naming both parents in the proceedings remains prudent litigation practice.

The defence: absence of fault in custody, supervision, and education. To rebut the presumption, the parents must demonstrate, on a balance of probabilities, that they committed no fault in the custody, supervision, and education of the minor. The obligation is one of means, not of result.

Custody and supervision (garde et surveillance). Courts require heightened vigilance for preschool-age children. For pre-adolescents and adolescents, they acknowledge that constant supervision is impossible. Tolerating the use of dangerous objects or situations where harm was foreseeable, particularly when such incidents have recurred without corrective measures, weighs heavily against the parents. The child's temperament and prior conduct inform the assessment.
Education (education). The parents must show that they instilled a sense of right and wrong, reinforced by their own example. School reports, testimony from teachers and persons in the child's environment, and the existence of coherent household rules all serve to support this proof.
Combined standard. Both components must be proven. The case law tends to associate a deficiency in education with the underlying cause (causa sine qua non) and a deficiency in supervision with the direct cause (causa causans). For younger children, the emphasis falls on supervision; for adolescents, it shifts toward education and framing.

Minors aged 14 and older. The CCQ progressively increases the legal autonomy of minors from the age of 14: capacity for acts relating to employment (art. 156 CCQ), emancipation available from 16 (arts. 167, 168 CCQ). Courts are reluctant to hold parents liable for the acts of minors approaching majority. Emancipation extinguishes the presumption. Majority at 18 terminates it in all cases (arts. 153, 175 CCQ). The tension between the fault presumption and the increased autonomy granted to minors over 14 remains a point of doctrinal reflection: the parents' real power of control over these "near-adult" minors often depends only on their economic leverage.

Deprivation of parental authority. A parent deprived of authority (art. 606 CCQ) remains bound under art. 1459, para. 2 if the minor's injurious act is related to the education that parent gave. The purpose is to prevent a parent who set a harmful example from escaping responsibility by losing formal authority. Where the deprivation occurred many years earlier, the causal link may be broken.

Example. A 15-year-old whose parents know of the child's impulsive temperament injures a classmate by misusing a metal tool at home. If the parents demonstrate that clear rules existed, that tools were stored in a locked space, and that the adolescent defeated the lock mechanism, they may rebut the presumption. If, by contrast, the parents knew the child regularly accessed the tools and took no corrective measures, their defence will be difficult to sustain.

Custodians, Supervisors, and Educators (art. 1460 CCQ)

Art. 601 CCQ permits the delegation (delegation) of attributes of parental authority to third parties. Art. 1460, para. 1 CCQ imposes on these delegates a presumption of fault when a minor in their charge causes injury through a fault or qualifying injurious act within the meaning of art. 1462 CCQ.

Persons covered. The terms "custodian (gardien), supervisor (surveillant), and educator (educateur)" in art. 1460, para. 1 CCQ are illustrative, not exhaustive. They cover teachers, daycare operators, sports coaches, camp counsellors, and any person to whom the parents have entrusted the child, whether by express agreement or implicitly. The legislature intended the presumption to extend broadly to anyone exercising a delegated attribute of parental authority.

Conditions of application. (1) Minority and the child's fault or qualifying injurious act (art. 1462 CCQ); (2) a delegation, express or tacit, of at least one attribute of parental authority; (3) causation and injury.

Scope of the duty. The obligations of the delegate correspond to those of the parents, but are limited to the activity and duration of the delegation. Art. 1460 CCQ does not reproduce the temporal limitation found in former art. 1054, para. 5 CCLC, which restricted the liability of teachers to the period during which the child was under their supervision. The current text may support liability even where the child's act occurs outside the period of direct supervision, provided the delegate's fault is causally linked to the injury.

Defence structure. Two showings are required:

General organisation: the measures in place (rules, supervisor-to-child ratios, safety equipment, discipline policies) were adequate and appropriate for the activity and the age group.
Unpredictability: the specific incident was not reasonably foreseeable and could not have been prevented despite these measures.

Courts do not require more of the delegate than they would of parents in comparable circumstances. Where the activity is age-appropriate and the rules are generally followed, an unexpected act by a child will not engage the delegate's liability.

Solidarity between parents and delegate. Solidarity is not presumed (art. 1525 CCQ), but co-liability may arise under art. 1526 CCQ when two extra-contractual faults concur to cause the same injury.

Gratuitous care (art. 1460, para. 2 CCQ). When the person acts gratuitously or for a "reward" (recompense, a broad term capable of encompassing any form of compensation), the presumption of fault is replaced by the regime of proven fault under art. 1457 CCQ. The plaintiff then bears the full burden of proof. The legislature sought to encourage socially useful volunteer care of children.

Tutor and Custodian of an Incapacitated Adult (art. 1461 CCQ)

Art. 1461 CCQ governs the liability of tutors and de facto custodians (gardiens de fait) for injury caused by an adult not endowed with reason (non doue de raison). The regime is deliberately lenient: liability arises only upon proof of gross fault (art. 1474 CCQ) or intentional fault in the exercise of custody. This threshold replaced the former presumption of fault, already attenuated by art. 1054.1 CCLC in 1989. The legislature determined that family members and close associates should be encouraged to assume custody of incapacitated adults without bearing a disproportionate burden of liability.

Obligations of the tutor. The duties of the tutor to a person of full age (tuteur au majeur) are framed by arts. 256 to 297 CCQ. The tutorship judgement defines the scope of the incapacity (art. 288 CCQ). The more clearly the incapacity is established before the injurious act, the more rigorously courts will scrutinise the measures the tutor took, and the more readily gross fault may be found.

De facto custodian. Art. 1461, para. 1 CCQ extended liability to factual custodians, an innovation of the 1994 Code. The obligations of de facto custodians are assessed under the general standard of art. 1457 CCQ. Delegation of physical custody to an institution (art. 260 CCQ) is possible and may create parallel exposures. The adult's act must be one that would have constituted a fault if the person had been endowed with reason (art. 1462 CCQ).

Example. A tutor is responsible for an adult with a documented tendency to wander into traffic. The tutor disables the apartment door alarm and allows the adult to leave unsupervised. The adult causes a collision. The deliberate disabling of a safety mechanism in a context of known risk is susceptible to a finding of gross fault.

The Role of Art. 1462 CCQ

Art. 1462 CCQ is the bridge provision (disposition charniere) that connects the special regimes of liability for another to situations involving persons not endowed with reason. For a child too young to distinguish right from wrong (generally under seven in Quebec case law, though the assessment is individual) or for an incapacitated adult, the Code cannot attribute a "fault" in the classical sense. Art. 1462 resolves this difficulty by providing that the act of such a person may be treated as an injurious act if, but for the absence of discernment, it would have constituted a fault.

This mechanism fulfils a precise function: it allows the victim to invoke the parental presumption (art. 1459), the delegate presumption (art. 1460), or the tutor/custodian regime (art. 1461), even when the person who directly caused the injury cannot personally be found at fault. Art. 1462 avoids imposing strict no-fault liability on young children or incapacitated adults while still enabling compensation through the intermediary of the responsible person.

A minor endowed with reason (doue de raison) remains personally liable for faults (art. 164 CCQ), and a judgement against the minor is enforceable for ten years (art. 2924 CCQ). In practice, the minor's liability is generally covered by the parents' insurance policy.

The Employer (art. 1463 CCQ)

Art. 1463 CCQ provides that the employer (commettant) is bound to make reparation for the injury caused by the fault of the employee (prepose) in the exercise of the employee's functions. The employer retains a recourse against the employee (art. 1463, para. 2 CCQ). This regime represents the most demanding form of vicarious liability within the architecture of the CCQ.

Nature of the presumption. Art. 1463 establishes an irrebuttable presumption of liability (presomption absolue de responsabilite). The employer cannot escape liability by proving an absence of personal fault. Once the three conditions are satisfied, the victim is entitled to reparation.

Conditions of application

Fault of the employee established under art. 1457 CCQ (or a more favourable regime). It is not necessary to identify the specific employee at fault when several employees participated in the same injurious event. Presumptions of fact (art. 2849 CCQ) may assist the plaintiff.
Relationship of subordination (lien de preposition). The defining element is the employer's power to set objectives and direct the methods of work. Several indicators are relevant:
- The power to assign tasks and set deadlines.
- The right to hire, discipline, and dismiss.
- Ownership of tools and equipment (relevant but not decisive).
- Remuneration (relevant but not indispensable; the relationship has been recognised in family, friendship, and neighbourly contexts).
- A written contract is not required; factual analysis prevails.
- The link may migrate: when effective control passes to a second employer (for example, through a temporary loan of labour), the second employer may become the commettant at the time of the injurious act. The test tracks real-time power of direction and control. In Kosoian c. Societe de transport de Montreal, the Supreme Court of Canada clarified the distinction between mandate and the relationship of subordination.
Within the exercise of functions (dans l'exercice des fonctions), and not merely on the occasion of employment. The victim must prove that the employee's fault occurred in the performance of assigned duties. The purpose test (test de finalite) is the principal guide: did the employee's actions serve the employer's objectives, or did they constitute a defective performance of assigned tasks? Several factors inform the analysis:
- Disobedience to express orders does not automatically place the act outside the exercise of functions.
- Criminal or intentional acts by the employee may fall within the scope of functions.
- In Axa Assurances Inc. c. Le Groupe de securite Garda Inc., the Court of Appeal identified five non-exhaustive criteria: (a) the opportunity for abuse of power that the employer furnished; (b) the extent to which the misconduct could have furthered the employer's objectives; (c) the relationship between the misconduct and the conflict inherent in the employer's enterprise; (d) the scope of authority conferred on the employee relative to the victim; and (e) the vulnerability of potential victims.
- If the employee's fault merely used the workplace as a backdrop for a purely personal act, the employer is exonerated.

Distinct personal fault of the employer. Art. 1463 alone does not create solidarity between employer and employee. Solidarity requires two concurrent extra-contractual faults (art. 1526 CCQ). A distinct employer fault (deficient supervision, inadequate training, tolerance of repeated negligent conduct) grounds an independent claim and may establish solidarity. The employer retains a recourse against the employee (art. 1463, para. 2), but rarely exercises it because insurance policies typically cover the employee (art. 2474 CCQ). Punitive damages are normally assessed against the employee personally.

Example. A night security guard deliberately sets a small fire in the building he is assigned to protect, intending to demonstrate his effectiveness by extinguishing it. The fire escapes and destroys the building. Because the employer placed the guard in a position of authority over the premises, and the guard's act, though intentional and misdirected, was connected to his protective functions, a court may classify the act as committed within the exercise of functions. Liability under art. 1463 would follow.

Liability for Things

Quebec law subjects the custodian of a thing, the owner of an immovable, and the owner or user of an animal to distinct regimes of presumed or strict liability. These regimes are extra-contractual: the presumptions under arts. 1465 and following do not apply between parties bound by a contract.

Custodian of a Thing (art. 1465 CCQ)

Art. 1465 CCQ creates a presumption of fault against the custodian (gardien) of a thing when injury results from the autonomous act (fait autonome) of that thing.

The autonomous act of a thing. The plaintiff must establish that the injury was caused by the thing's own dynamism, without direct human intervention at the time of the incident. If a person is actively controlling the thing at the time of the injury, the thing has not acted autonomously and the general fault regime of art. 1457 CCQ applies. By contrast, if human involvement was limited to setting the thing in motion (pressing a start button, triggering a mechanism), the thing's subsequent action remains autonomous. Inert things may also act autonomously when they become active through the laws of physics (gravity, internal pressure, temperature). The thing must be the cause of the injury, not simply the occasion for it. A spontaneous burst in a water main activates art. 1465; a perforation of the same pipe caused by construction work falls under art. 1457.

The notion of "thing." The former CCLC used the term "chose" (thing); the current Code uses "bien." The term encompasses corporeal and incorporeal property, movables and immovables (art. 899 CCQ). The case law has extended the presumption to gas, electric current, and vapours. In fire cases, the plaintiff must show that the fire was caused by the autonomous act of a specific thing, since fire in the abstract is not a "thing" within the meaning of art. 1465.

Identification of the custodian. Custody is a factual concept: the custodian is the person who had the use, direction, surveillance, and control of the thing at the time of the autonomous act. Custody does not depend on ownership. The determination is case-specific and may be informed by contracts, leases, and co-ownership declarations.

Exoneration of the custodian. The presumption under art. 1465 is a presumption of fault, not strict liability. The custodian may rebut it by establishing one of the following defences:

Absence of fault. The custodian proves that reasonable maintenance was performed, that appropriate safety measures were in place, and that a reasonable person in the same circumstances could not have prevented the incident. The obligation is one of means.
Superior force (force majeure) (art. 1470 CCQ): an external, irresistible, and unforeseeable event.
Fault of the victim (art. 1478 CCQ): may exonerate in whole or in part according to the victim's contribution.
Fault of a third party: accepted only if the custodian also establishes an absence of personal fault.

Coexistence with art. 1467 CCQ. When the same person is both custodian and owner of an immovable, arts. 1465 and 1467 may be cumulated.

Example. A municipal water main, installed thirty years earlier, bursts spontaneously and floods a commercial premises. The municipality presents evidence of regular inspections and compliance with engineering best practices. An expert confirms that the metallurgical failure was undetectable by available inspection technology. The municipality may establish its absence of fault. If, by contrast, residents had reported recurrent leaks and the municipality had deferred repair, the defence would fail.

Ruin of an Immovable (art. 1467 CCQ)

Art. 1467 CCQ imposes a near-absolute presumption on the owner of an immovable when injury results from its ruin (ruine). This regime ranks among the strictest in the CCQ.

"Ruin" defined. Ruin means the total or partial disintegration of an immovable or a structurally integrated element thereof: a brick detaching from a wall, a balustrade collapsing, a staircase giving way, an elevator failing. Objects merely placed on the immovable (a flower pot on a windowsill) are not covered.

Cause of the ruin. The ruin must be attributable to a construction defect (vice de construction) or a lack of maintenance (defaut d'entretien). In practice, the ruin itself frequently gives rise to an inference of one or the other.

Identification of the owner. The presumption binds the holder of the right of ownership (titulaire du droit de propriete). In divided co-ownership, whether the failing element is a common or a private portion determines whether the syndicate of co-owners or an individual co-owner is liable (art. 900 CCQ).

Cumulation with art. 1465 CCQ. Art. 1467, para. 2 expressly permits cumulating its presumption with that of art. 1465 when the owner is also the custodian. The conditions differ: art. 1465 requires an autonomous act; art. 1467 requires ruin linked to a construction defect or maintenance failure.

Narrow defences. The owner cannot escape liability merely by proving general good maintenance. Once ruin is established, the presumption is near-absolute. The defences are limited to:

Superior force (art. 1470 CCQ), bearing in mind that buildings are expected to withstand extreme conditions and building codes impose rigorous construction standards.
Fault of the victim or fault of a third party (art. 1478 CCQ).
Contractual limitation: possible between the parties for material damage, but clauses limiting liability for bodily injury are null (art. 1474, para. 2 CCQ), and no contractual clause is opposable to third parties.

The owner retains a recourse against the constructor, engineer, or maintenance provider whose defect or negligence caused the ruin (arts. 2100, 2118 CCQ).

Example. A facade brick detaches from an aging building and injures a pedestrian. The owner cannot resist the claim by invoking a recent cleaning contract. Unless the owner establishes superior force or the fault of the victim or a third party, liability follows.

Animals (art. 1466 CCQ)

Art. 1466 CCQ imposes no-fault liability (responsabilite sans faute) on the owner and the user (usager) of an animal for injury caused by that animal. This regime is the clearest instance of strict liability in the CCQ.

Scope. The provision covers domestic or domesticated animals over which a person exercises or can exercise control. Wild animals belonging to no one (res nullius, art. 934 CCQ) do not engage this regime. The term "user" is interpreted broadly to include any non-owner exercising real and concrete factual control over the animal.

Persistence of the owner's liability. The owner is liable when in physical custody of the animal and when the animal has escaped. When a third party uses the animal, the owner's liability is cumulative with that of the user. Physical contact between the animal and the victim is not required.

Narrow defences. The owner and user cannot exonerate themselves by proving an absence of fault, unlike the custodian under art. 1465. Only two defences are available:

Superior force (art. 1470 CCQ).
Fault of the victim (art. 1478 CCQ): provocation of the animal or deliberate disregard of a known danger may found a full or partial defence. Courts tend to temper the victim's fault where the animal had a vicious or aggressive temperament.

Fault of a third party may sometimes be assimilated to superior force. Whether solidarity applies between the owner and the user is determined case by case under art. 1526 CCQ.

Example. A horse boarded at a stable rented by a riding school escapes through an unlocked gate and causes a highway collision. The owner of the horse and the riding school (user exercising factual control) are both subject to no-fault liability. The owner cannot defeat the claim by pointing to the stable hand's fault; the owner's recourse lies against the stable hand or the school. Only superior force or the victim's own fault would reduce the defendants' exposure.

Manufacturer, Distributor, and Supplier Liability

The Civil Code of Lower Canada never specifically addressed the extra-contractual liability of manufacturers. Under art. 1053 CCLC, the victim had to prove that the injury was attributable to the product and that the deficiency resulted from a fault in the design, manufacture, or marketing, a burden that was often prohibitive in practice. The CCQ remedied this gap by introducing an objective regime founded on the concept of safety defect.

Safety Defects (arts. 1468, 1469 CCQ)

Art. 1468 CCQ provides that the manufacturer of a movable thing (bien meuble), even after its incorporation into an immovable, is bound to make reparation for injury caused to a third party by a safety defect in the thing. Professional distributors and suppliers are subject to the same obligation (art. 1468, para. 2 CCQ).

Who is covered? The manufacturer is the person who transforms raw materials or organises the components of a product into a usable movable thing (designers, assemblers, component fabricators). The term "distributor" or "supplier" covers every professional intermediary who places the product on the market: wholesalers, retailers, lessors, lenders. A distributor who identifies with the product (for example, by affixing its trade mark) is fully subject to the regime. Simple brokers who do not identify with the product and non-professional private sellers are excluded. Art. 1468 CCQ applies to every movable thing resulting from a process of fabrication, including those incorporated into immovables (elevators, heating systems, glazed curtain walls, structural beams).

Art. 1469 CCQ: the definition of the safety defect. Art. 1469 CCQ defines the safety defect by reference to the safety one is normally entitled to expect, assessed according to the product's normal use and the expected knowledge of its users. The Code provides an illustrative list:

Design defect (vice de conception): the product's design itself creates an unreasonable risk under normal conditions of use. The defect affects the entire production line.
Manufacturing defect (vice de fabrication): a deviation from the intended design during the production process renders a particular unit or batch unsafe.
Preservation defect (mauvaise conservation): the product deteriorated during storage, handling, or transport in a manner that creates a safety risk.
Presentation defect (mauvaise presentation): the product's packaging, labelling, or marketing misrepresents its safety-relevant characteristics.
Insufficient warnings (absence d'indications suffisantes): the manufacturer failed to provide adequate information about the product's risks or the means of protection against them. Warnings must be "truthful, precise, comprehensible, and complete."

Plaintiff's burden. The victim must prove the safety defect, the injury, and the causal link between them. Once these elements are established, arts. 1468 and 1469 operate a presumption of liability (sometimes characterised as a presumption of knowledge of the defect). The victim need not prove a specific fault in the manufacturing process.

Defences and Exoneration (art. 1473 CCQ)

User knowledge (art. 1473, para. 1 CCQ). The defendant may demonstrate that the victim knew or could have known the safety defect. The user's knowledge must have been sufficient to apprehend the nature of the danger and the associated risk. Despite the provision's wording as a complete bar, the Supreme Court of Canada reconciled this rule with the general apportionment principles of arts. 1477 and 1478 CCQ. Unless the user's knowledge amounts to a virtual renunciation of the right to sue, the result may be a partial reduction rather than a complete defence.

State of knowledge (art. 1473, para. 2 CCQ). The manufacturer, distributor, or supplier may prove that the safety defect could not have been known given the objective state of scientific and technical knowledge at the time of manufacture or distribution. "State of knowledge" is assessed objectively: it refers to the collective knowledge of all relevant scientific and technical participants on the market, not to the defendant's subjective awareness.

Continuing duty to inform. Art. 1473, para. 2 in fine conditions the state-of-knowledge defence on an obligation of post-market vigilance: once the manufacturer, distributor, or supplier becomes aware of a safety defect, it must inform users. Failure to do so forfeits reliance on the state-of-knowledge defence. This obligation operates as a practically continuous duty, which significantly attenuates the defence's utility.

The duty to warn and the learned intermediary. The manufacturer's obligation to inform purchasers and users of dangers associated with normal use of its products is well established. Since Wabasso, the Supreme Court of Canada has firmly recognised this duty. The CCQ codifies it on the extra-contractual side through art. 1469 CCQ, which treats insufficient warnings as a safety defect. For products with a high technical content, or products for which the consumer relies on the judgement of a professional (a physician for medical devices or pharmaceuticals), the manufacturer may discharge its warning obligation by informing the learned intermediary (intermediaire competent) rather than the end user. The Supreme Court recognised this doctrine in Dow Corning, and the Quebec Court of Appeal has admitted it in comparable health-care contexts. The learned-intermediary doctrine applies only to the warning-defect limb; it cannot excuse a design or manufacturing defect.

General defences. Superior force (art. 1470 CCQ) and fault of the victim (art. 1478 CCQ) apply. Apportionment between co-defendants is possible but not opposable to the victim; co-defendants are liable solidarily or in solidum.

Consumer protection law. The Consumer Protection Act (Loi sur la protection du consommateur, L.p.c.) reinforces the victim's position. Art. 53, para. 3 L.p.c. establishes an absolute presumption of knowledge of the defect against the manufacturer, which eliminates any state-of-knowledge defence in the context of a claim under that statute.

The Contractual-Extra-Contractual Boundary

Art. 1458, para. 2 CCQ prohibits contracting parties from opting into the extra-contractual regime. Between direct contracting parties, product-liability recourses must follow the contractual path: the seller's warranty of quality (garantie de qualite, arts. 1726 to 1731 CCQ), the implied obligation of information and safety (art. 1434 CCQ), or the Consumer Protection Act (art. 53 L.p.c.).

Third parties (persons with no contract with the manufacturer or supplier) proceed under arts. 1468 to 1473 CCQ.

The position of the sub-purchaser (sous-acquereur) is more nuanced. Under General Motors Products du Canada c. Kravitz, the sub-purchaser may exercise the warranty rights transmitted accessorily with the thing (art. 1442 CCQ). The Quebec Court of Appeal also recognises that the sub-purchaser, who did not personally contract with the manufacturer, may invoke the extra-contractual regime. The prohibition of option under art. 1458, para. 2 is read as applying only where the victim's claim is founded exclusively on an obligation arising from a contract to which the victim is a party.

The duty to inform over time. The duty to inform users of dangers is rooted in the long-standing case law of Quebec courts, confirmed by Vaillancourt c. Governor and Company of Gentlemen Adventurers of England. The CCQ codifies this duty through art. 1469 CCQ (insufficient warnings equal a safety defect) and art. 1434 CCQ on the contractual side. The duty evolves over time: a manufacturer who discovers new risks after placing the product on the market must issue updated warnings.

Example. A homeowner buys a furnace from a retailer. The furnace, manufactured by a third company, contains a design defect that causes a fire. The homeowner may pursue the retailer under the warranty of quality (arts. 1726 to 1731 CCQ) or under the L.p.c. Against the manufacturer, the homeowner may invoke the warranty rights transmitted with the thing (art. 1442 CCQ) or, on the reading accepted by recent Court of Appeal jurisprudence, the extra-contractual regime of arts. 1468 to 1473 CCQ. A neighbouring bystander injured in the same fire proceeds exclusively under arts. 1468 to 1473.

Practice Checklist

Parents (art. 1459 CCQ)

Prove filiation or authority, minority, the child's fault or qualifying injurious act (with art. 1462 where discernment is lacking), injury, and causation.
For the defence, assemble evidence of custody, supervision, and education: rules, prior incidents and corrective measures, school reports, testimony of third parties.
Adapt the defence to the child's age and autonomy; consider emancipation or the practical limits on parental control for adolescents aged 14 and older.

Delegated custodians (art. 1460 CCQ)

Establish the delegation (express or tacit) and the delegate's role (custodian, supervisor, educator).
Document the general organisation and the unforeseeable character of the specific incident.
If the custodian acts gratuitously or for a reward, frame the case under art. 1460, para. 2: the plaintiff bears the burden of proving fault.

Tutor or de facto custodian (art. 1461 CCQ)

Obtain and review the tutorship judgement and the scope of the incapacity.
Assess the facts against the gross fault or intentional fault threshold.
Verify any delegation to an institution and evaluate possible cumulative exposures.

Employer (art. 1463 CCQ)

Confirm the employee's fault; articulate the relationship of subordination using concrete indicators.
Analyse the exercise of functions by reference to purpose and risk.
Examine whether a distinct personal fault of the employer exists (training, supervision, tolerance of negligent conduct).
Evaluate the fault of a third party or superior force.

Custodian of a thing (art. 1465 CCQ)

Prove the autonomous act of the thing and identify the custodian.
For the defence, build a record of maintenance and of the impossibility of prevention.

Ruin of an immovable (art. 1467 CCQ)

Establish the ruin of a constituent element of the immovable and its link to the injury.
Identify the owner (common or private portion in co-ownership).
Anticipate that proof of general good maintenance alone will not rebut the presumption; focus on superior force or the fault of the victim or a third party.

Animals (art. 1466 CCQ)

Name the owner and the user in the alternative where appropriate; no-fault liability applies.
Assess superior force and any provocation by the victim or disregard of a known risk.

Products (arts. 1468 to 1473 CCQ)

Identify the manufacturer and professional suppliers.
Prove the safety defect, injury, and causation; gather evidence on warnings and product presentation.
Anticipate the state-of-knowledge and user-knowledge defences; verify compliance with the post-market duty to inform.
Respect the contractual channelling rule of art. 1458, para. 2 where applicable; consider recourses under the L.p.c. for consumers and the sub-purchaser's option.
