Medical and Hospital Liability

Overview

Medical and hospital liability occupies a distinct place within the broader law of extra-contractual liability (responsabilité civile) in Quebec. The relationship between a patient and a physician or healthcare institution raises questions that cut across the contractual and extra-contractual regimes, demanding close attention to the nature, intensity, and scope of the obligations at stake. Quebec courts have developed a rich body of case law on the duties of the physician (to diagnose, inform, treat, and maintain confidentiality) and on the circumstances in which a hospital may be held liable, whether for its own organizational faults or for the acts of its personnel. This lesson surveys those rules, highlights the continuing doctrinal debates, and identifies the practical consequences that flow from each classification.

The Nature of the Medical Obligation

Contractual or Extra-Contractual?

The characterization of the patient-physician and patient-hospital relationship as contractual or extra-contractual has been one of the most persistent debates in Quebec medical law. The distinction matters: it affects the available regime for liability for the acts of others, the scope of reparable damage, and the procedural posture of the claim.

The contractual thesis. For decades, Quebec courts applied the contractual framework. In the landmark decision X c. Mellen, the Court of King's Bench held that a contract of professional care arises from the moment a patient enters a physician's office. Supporting this view, commentators argued that the meeting of wills between patient and physician gave rise to a valid innominate contract, provided the requirements of art. 1385 CCQ (consent, capacity, cause, and object) were satisfied. Later decisions confirmed this approach, and it became the dominant position for several decades.

The extra-contractual thesis. Other scholars challenged the contractual characterization head-on. In their view, healthcare relationships are so extensively regulated by statute that the hospital does not give genuine consent; its participation is imposed by law. A missing element of the contract (the meeting of wills) removes the relationship from the contractual sphere altogether.

The state of the law. The Quebec Court of Appeal addressed the question in Camden-Bourgault. Writing for the court, Rochon J.A. rejected the contractual thesis for the patient-hospital relationship in the context of medical acts. The court held that (1) the hospital is not free to consent, making a "contract" fictitious; (2) no relationship of employer-employee (lien de préposition) exists between the hospital and the physician performing a medical act; and (3) absent a specific legislative text, there is no strict liability for hospital centres.

The Supreme Court of Canada, in Lapointe c. Hôpital Le Gardeur, declined to rule definitively on the issue, leaving the controversy formally open. Subsequent decisions, including Hôpital de Chicoutimi c. Battikha, have acknowledged that a physician may sometimes become an employee of the hospital depending on the concrete organization of care.

For specific areas such as deficient nursing care, equipment failure, and hotel-type services, the contractual characterization remains plausible. Professional writing and practice should therefore account for both frameworks.

The Intensity of the Obligation

Neither the physician nor the hospital guarantees the result of treatment, namely the patient's recovery. The Code of Ethics of Physicians (Code de déontologie des médecins) prohibits a physician from guaranteeing the cure of a disease. Instead, the physician must take all reasonable and available means to pursue that goal. The obligation is accordingly classified as an obligation of means (obligation de moyens).

The standard of care is that of the reasonably prudent, diligent, and competent physician placed in the same circumstances. The court does not ask whether the defendant physician departed from his or her own habits; it applies an abstract model. As Pierre Deschamps has explained, the benchmark is the standard conduct that a reasonably prudent and diligent physician would have adopted under the same conditions.

This abstract criterion is refined by several contextual factors:

Knowledge of the era: The physician is judged according to the medical knowledge available at the time of the act.
Circumstances: Emergency, geographic isolation, and available resources all bear on the assessment.
Degree of specialization: A cardiologist is measured against the standard of the prudent and diligent cardiologist. A general practitioner who ventures beyond the scope of general practice will be evaluated against the specialist standard.

In limited situations, the obligation becomes one of result. Where the physician expressly undertakes to achieve a particular outcome, the obligation is transformed by convention. A statutory deadline may similarly impose a result-type obligation. The counting of surgical sponges (compresses) is treated as an obligation of result, and organizations responsible for transfusing contaminated blood have been held to a result-standard in French jurisprudence.

Presumptions in Medical Liability

Direct proof of medical fault is often difficult. To assist victims, Quebec courts apply two types of presumptions under art. 2849 CCQ.

Presumption of fault. A court may reverse the burden of proof and require the physician to demonstrate the absence of fault when two conditions are met: (1) the injury is shown to result, prima facie, from a medical intervention; and (2) an abnormal event occurred during the normal course of care, one that should not have happened. From that abnormality, the court infers fault.

To rebut the presumption, the physician need only show conformity with the standard of the reasonably prudent and diligent physician. Some authorities have demanded proof of the exact cause of the accident, but the better view, consistent with the obligation-of-means framework, is that demonstrating reasonable conduct suffices.

Presumption of causation. Causation (lien de causalité) must ordinarily be established on a balance of probabilities. Courts may use presumptions of fact under art. 2849 CCQ, and the trial judge enjoys broad discretion. Some decisions have inferred causation where a fault created a danger and that danger materialized, though more recent case law has cast doubt on this approach.

Professor Daniel Jutras has observed that applying presumptions in medical contexts requires caution: presumptions of fact rest on the premise of an abnormal situation, whereas medicine often treats the adverse event as an inherent risk rather than an anomaly.

The Personal Liability of the Physician

The physician's personal duties toward the patient revolve around four axes: diagnosis, information, treatment, and confidentiality.

The Duty to Diagnose

A diagnosis (diagnostic) is the determination of the nature of a disease based on information provided by the patient, clinical signs and symptoms, and laboratory results. Because diagnosis is inherently an opinion, it may prove incorrect. The question is whether the physician took reasonable and necessary precautions and used adequate techniques to make a conscientious determination.

Recognized diagnostic faults include: failure to consult the patient's data-collection file; failure to conduct a preliminary examination; an incomplete or superficial examination; failure to order deeper investigations (e.g., radiography); and issuing an inaccurate insurance-disability form that causes the patient's claim to be denied. When in doubt, the physician must seek a consultation or refer the patient to a specialist. If more advanced tests that would yield a more precise diagnosis were still at the experimental stage, the physician cannot be faulted for not performing them. A clear distinction must be drawn between a test that has passed all validation stages and one that remains in the phase of scientific exploration.

The physician will not be held liable for a diagnostic error that stems from a genuine medical controversy. Where two schools of thought coexist, the court will not arbitrate between them. A diagnostic error is also more readily excused if it occurred in an emergency or involved a particularly rare condition.

The physician's degree of specialization is relevant: the Superior Court has declined to hold a general practitioner liable for diagnosing a sprain when the injury was in fact a tendon rupture, noting that an orthopaedic specialist would likely have identified the rupture, but that the defendant, given the difficulty of the case, had proceeded correctly.

Failure to record accurate notes in the patient's file, failure to communicate the diagnosis, and concealment of a diagnostic error all constitute faults.

The physician owes the patient (or a close relative if the patient cannot consent) an obligation to provide the information necessary for informed consent (consentement éclairé). This duty is a corollary of the principle of inviolability of the person and establishes a decision-making process that respects the patient's choices.

Scope of the duty. The physician must disclose all risks that a reasonably prudent and diligent physician would have communicated. The analysis focuses on the conduct of the debtor of the information obligation, not on the expectations of the creditor. Contextual factors, including the urgency of the situation and the individual characteristics of each patient, refine the duty. If the physician has fulfilled the information obligation, no fault exists and causation need not be considered.

Content of the information. The physician must disclose, among other things: absence of specialization, the purpose and nature of the intervention, the principal foreseeable consequences (operative and post-operative risks), and available therapeutic alternatives. The more serious the risk (paralysis, death), the stronger the duty to disclose. For purely cosmetic or non-therapeutic interventions, the obligation extends to rarer side effects. Where care is not required by the patient's state of health, art. 24 CCQ requires written consent.

Causation and informed consent. If the physician's fault in failing to inform is established, the court must determine whether the patient would have refused the intervention had adequate information been provided. Quebec doctrine favours a mixed (objective-subjective) test: the court assesses what the particular patient would have decided, then verifies whether that reaction accords with what a reasonable person would have chosen. The Quebec Court of Appeal has stated that the subjective test is primary and the objective test is complementary.

A presumption of fact may arise where the failure to inform is paired with disastrous consequences: the court may presume that the patient would have refused the intervention, shifting the burden to the physician to prove otherwise.

Identity of the operator. If a major portion of the intervention is to be performed by someone other than the treating physician, the patient must be informed. A patient treated in a university-affiliated hospital is generally deemed to have accepted the presence of trainees, provided the treating physician supervises. The Supreme Court of Canada, in Marcoux c. Bouchard, held that the patient has the right to know the identity of the principal actors in the intervention, though this does not extend to customary auxiliaries such as anaesthetists, nurses, or residents.

The information provided must be intelligible to the patient, taking into account the patient's level of education. If unforeseen circumstances arise during the intervention, the physician must obtain fresh consent; the duty to inform is a continuing obligation. If delaying the intervention creates greater danger (art. 13 CCQ), the physician may proceed without renewed consent.

The Duty to Treat

The physician must administer treatment in accordance with the rules of the art and provide attentive, conscientious care within a reasonable time. The physician must respond to the patient's reactions and cannot blindly accept a colleague's diagnosis without questioning it where warranted.

A physician who has used a treatment recognized and current at the relevant time is normally shielded from liability, provided that the prevailing practice is itself reasonable. New or unorthodox methods are permissible only if the patient has been adequately informed of their nature and risks.

Where a general practitioner elects to perform treatments falling within a specialist's domain and a specialist is available, the care provided will be measured against the specialist standard. This rule does not apply where circumstances (e.g., emergency) justified the general practitioner's immediate intervention.

The Court of Appeal has confirmed that courts do not arbitrate controversies within the medical profession. Where two recognized approaches to treatment exist, a physician who selects one does not commit a fault merely because others in the profession prefer the alternative.

The duty to treat also encompasses prescription of appropriate medication, informing the patient of post-operative risks, and providing reasonable follow-up. If the physician is absent, coverage by a competent replacement must be arranged. The patient, for his or her part, has a duty of cooperation and must take the initiative to contact the physician when an abnormal situation arises.

The Duty of Confidentiality

The physician is bound by professional secrecy (secret professionnel), a duty elevated to the status of a fundamental right by the Charter of Human Rights and Freedoms (Charte des droits et libertés de la personne). The Code of Ethics of Physicians requires the physician to keep confidential all information learned in the exercise of the profession, including the very fact that a specific person is a patient.

The physician must also ensure that employees respect confidentiality. Under the principles of contractual liability for the acts of others, the physician is responsible for employees' indiscretions unless force majeure is established (art. 1470 CCQ). Judges may, on their own initiative, declare inadmissible any evidence that violates the rules on patient-physician confidentiality (art. 2858, para. 2 CCQ).

Several justifications underlie the duty: respect for the patient's private life (arts. 9 to 12 CCQ), the promotion of trust between physician and patient, and the dignity of the profession.

Exceptions. Confidentiality may be set aside where the patient or the law authorizes disclosure, where a compelling reason related to the health or safety of the patient or others exists, or where statute imposes a reporting obligation (e.g., notifiable diseases). A patient who sues the physician for professional fault is deemed to have implicitly renounced professional secrecy to the extent necessary for the defendant's full defence. The Supreme Court of Canada extended this principle to persons who take out life insurance.

Physician Liability for the Acts of Others

Modern medicine is practised collectively. Specialization, team-based care, and the growing number of auxiliaries who participate in patient treatment raise the question of whether the treating physician may be held liable for the faults of others.

Under the Extra-Contractual Regime

If the physician-patient relationship is characterized as extra-contractual, the physician may be liable as employer of another (commettant) under art. 1463 CCQ when three conditions are met: (1) a relationship of subordination (lien de préposition) with the employee; (2) a fault by the employee; and (3) the fault was committed in the exercise of the employee's functions.

Nurses, students, and residents are generally considered employees. The identity of the employer at the relevant moment requires careful factual analysis: the hospital is ordinarily the employer, but the physician may become the momentary employer (commettant momentané) if the auxiliary was acting under the physician's specific direction and control.

A specialist physician cannot normally be considered the employee of another physician, given the absence of effective control. The employer retains a right of recourse against the employee (art. 1463 CCQ), though a contractual clause could exclude this right, except in cases of intentional or gross fault.

Under the Contractual Regime

Under the contractual thesis, the physician is liable for all persons who execute the physician's obligations in whole or in part, without any need to establish a relationship of subordination. The maxim qui facit per alium facit per se applies: a contracting party who delegates performance remains responsible for the delegate's fault. If the third party intrudes of his or her own initiative, the physician may invoke force majeure (art. 1470 CCQ).

Substitution during absence. When the physician is replaced, two contracts coexist: the original physician-patient contract remains in force, and a new contract forms between the replacement and the patient. The replaced physician must inform the patient and select a reasonably competent substitute, failing which personal fault may be established. An illustration is Bergstrom c. G., where the treating physician's failure to follow up during his absence grounded personal liability.

Team-based care. Some decisions have held the "chief" of the medical team (typically the surgeon) liable for the faults of other physicians, applying the contractual liability-for-others framework. Subsequent case law has criticized this view, noting that a surgeon is entitled to rely on the competence of the anaesthetist and other colleagues. The Court of Appeal has questioned the characterization of the surgeon as "emperor of the operating room." The contractual liability of a physician for another's medical acts in a team setting has therefore receded.

Hospital Liability

Direct Institutional Liability

A hospital may be held liable for its own organizational faults, distinct from any fault by a physician or auxiliary. The hospital's direct obligations include:

Accommodation and safety: Providing appropriate premises, adequate equipment, and safe conditions. Hospitality-related obligations (sometimes compared to hotel services) require that the patient be housed in security. In Bacon c. Hôpital du St-Sacrement, the court declined to hold the hospital liable for a patient who fell from a window, finding that the hospital had taken the precautions that ordinary prudence required.
Competent staffing: Imposing an excessive workload or providing insufficient personnel may constitute a fault. In Côté c. Hôpital l'Hôtel-Dieu de Québec, the hospital was held liable along with the anaesthetist for requiring the latter to cover three operating rooms simultaneously, leading to a thrombosis that left the patient permanently paralysed.
Follow-up beyond hospital walls: An institution that sends a convalescing patient to another facility must ensure that adequate reception arrangements are in place.
Information, confidentiality, and diagnosis: The hospital bears the same duties as the physician with respect to information, confidentiality, and contributing to the diagnostic process.

The assessment of hospital fault takes into account the institution's mandate, the urgency of the situation, and the resources available.

Hospital Liability for the Acts of Others

Extra-contractual regime (art. 1463 CCQ). The hospital is liable for the faults of its employees acting in the exercise of their functions. Auxiliary staff, nurses, students, residents, and radiology technologists are generally considered employees. The practical difficulty lies in proving which entity was the employer at the precise moment of the wrongful act, because control may shift to the physician (the "momentary employer"). In Hôpital général de la région de l'Amiante Inc. c. Perron, the Court of Appeal stated that nurses are, as a general rule, employees of the hospital, but may come under the immediate direction and control of the physician during specific acts.

As for physicians themselves, the traditional view denied the existence of a relationship of subordination between the hospital and the physician, citing the physician's professional independence. In Camden-Bourgault, the Court of Appeal confirmed that the physician is not the hospital's employee in the context of medical acts. Some scholars, invoking modifications to the Health and Social Services Act (Loi sur les services de santé et les services sociaux) in 1991, have argued that the institution now bears a personal obligation to furnish care, which would make it liable through the maxim qui agit per alium agit per se without recourse to vicarious-liability principles.

Contractual regime. Under the contractual thesis, the hospital is liable for all persons who execute the hospital's contractual obligations toward the patient, without requiring proof of a relationship of subordination. In Lapointe c. Hôpital Le Gardeur, the Court of Appeal held that the hospital's obligation at the emergency ward encompassed the provision of competent medical services and that the hospital was responsible for the physician's faults committed in the execution of those services. Where the patient's visit is preceded by a consultation with a personal physician, two parallel contracts coexist, and the respective obligations of the physician and the hospital must be delineated on a case-by-case basis.

Practice Checklist

Determine whether the claim is best characterized as contractual or extra-contractual (or both), noting the continuing uncertainty in the case law.
Identify the applicable standard of care: reasonably prudent, diligent, and competent physician, adjusted for degree of specialization and circumstances.
For each alleged fault, specify which of the four duties (diagnosis, information, treatment, confidentiality) is engaged.
Where direct proof of fault is difficult, assess whether a presumption of fault based on art. 2849 CCQ may be available.
For informed consent claims, analyze causation using the mixed objective-subjective test: would this patient, and would a reasonable person, have refused the intervention?
Where liability for the acts of others is alleged, determine the identity of the employer (commettant) at the precise moment of the wrongful act and verify whether the employee was in the exercise of his or her functions.
In a hospital-liability claim, distinguish organizational (direct) faults from vicarious liability, and identify whether the contractual or extra-contractual pathway is more appropriate.
Verify whether exceptions to confidentiality apply before disclosing patient information.
In team-based care, assess whether the "chief physician" theory or the "egalitarian team" approach applies on the facts.
