Psychotherapy & Counselling Malpractice Claims in Atlantic Canada

Therapists and counsellors hold a position of deep trust. When that trust is breached, through boundary violations, negligent treatment, or failures to protect, the harm is real and compensable. A guide for Atlantic Canada.

Who Regulates Psychotherapists and Counsellors in Atlantic Canada?

Regulation of psychotherapists and counsellors in Atlantic Canada is a patchwork of provincial legislation, regulatory colleges, and voluntary professional associations that varies significantly between provinces and between professional categories. Understanding this landscape is important before taking any steps toward a complaint or legal claim.

Nova Scotia

Counselling therapists are regulated by the Nova Scotia College of Counselling Therapists (NSCCT), established under the Counselling Therapists Act. The protected titles are Registered Counselling Therapist (RCT) and Registered Counselling Therapist, Candidate (RCT-C). The NSCCT requires a master's level degree in a relevant field, a supervised practicum, and at least 2,000 hours of post-degree supervised practice.

Psychologists are regulated by the Nova Scotia Regulator of Psychology (NSRP), formerly known as the Nova Scotia Board of Examiners in Psychology. Registration requires a doctoral degree, supervised practice, and examinations.

Social workers are regulated by the Nova Scotia College of Social Workers (NSCSW).

New Brunswick

Counselling therapists are regulated under New Brunswick legislation. The protected title is Licensed Counselling Therapist (LCT), regulated by the College of Counselling Therapists of New Brunswick (CCTNB). Use of the title “Licensed Counselling Therapist” or its derivatives by an unregistered person is a regulatory offence.

Psychologists are regulated by the College of Psychologists of New Brunswick (CPNB).

Social workers are regulated by the New Brunswick Association of Social Workers (NBASW).

Prince Edward Island

Counselling therapists are regulated under the Regulated Health Professions Act by the College of Counselling Therapy of Prince Edward Island (CCTPEI), proclaimed in 2021, which protects the title “counselling therapist.”

Psychologists are regulated by the PEI Psychologists Registration Board.

Social workers are regulated by the PEI Social Work Registration Board.

Newfoundland and Labrador

Psychologists are regulated by the Newfoundland and Labrador Psychology Board (NLPB).

Social workers are regulated by the Newfoundland and Labrador College of Social Workers (NLCSW).

The Regulation Gap: What Happens When Your Practitioner Is Not Regulated

Across Atlantic Canada, there is a meaningful gap between who may hold themselves out as a therapist or counsellor and who is subject to professional regulatory oversight. The Canadian Counselling and Psychotherapy Association (CCPA) has identified this gap as a patient safety concern.

A practitioner who does not hold a regulated credential may still owe a duty of care in negligence if they have held themselves out as providing therapeutic services and a therapeutic relationship has been established. However:

  • There may be no regulatory college to which a complaint can be filed.
  • The practitioner may not carry professional liability insurance, making any judgment difficult or impossible to collect.
  • Expert evidence may be harder to obtain, as the applicable standard of care for an unregulated practitioner is less clearly defined than it is for a college member.

If you are unsure whether your practitioner held a regulated credential, you can check the public registries of the relevant provincial colleges for each profession.

The Canadian Counselling and Psychotherapy Association

The CCPA is a national professional organization that provides voluntary certification through the Canadian Certified Counsellor (CCC) credential. While this is not statutory regulation, it represents a recognized professional standard and requires adherence to a code of ethics, continuing education, and a disciplinary process. In provinces where counselling therapy is not regulated, CCPA certification is often treated as a meaningful indicator of professional standing.

Duty of Care in the Therapeutic Relationship

The legal concept of duty of care is the foundation of any malpractice claim. In the context of psychotherapy and counselling, this duty takes on dimensions that are distinct from other areas of healthcare, shaped by the uniquely personal and confidential nature of the therapeutic relationship.

How a Therapeutic Relationship Is Established

A duty of care arises when a therapeutic relationship is established. This does not require a formal signed agreement or an extended course of treatment. Courts have found that a duty of care can be established by a single session, a telephone intake call, or an assessment where the practitioner assumed responsibility for the client's care and the client reasonably relied on the practitioner's skill and judgment.

The relationship can be established with practitioners across the full spectrum, registered counselling therapists, psychologists, registered social workers, and in appropriate circumstances, even unregulated practitioners who have held themselves out as providing therapeutic services.

Once the relationship is established, the practitioner owes the client a duty to provide care that meets the accepted standard of their profession.

The Standard of Care for Psychotherapists and Counsellors

The standard of care in mental health treatment is defined by what a reasonably competent practitioner in the same discipline, with the same training and resources, would have done in the same circumstances. It is not perfection and it accounts for the genuine uncertainty inherent in mental health assessment and treatment.

Expert evidence is always required to establish what the applicable standard of care was and whether the practitioner's conduct met it. Courts have consistently held that negligence is not established simply because an outcome was poor, what is required is that a competent practitioner with the same information would have made a materially different decision.

The Duty to Warn: Obligations to Third Parties

One of the most distinctive aspects of mental health law is the duty to warn, the obligation that can arise when a client communicates an intention or credible threat to harm an identifiable person.

The foundational Canadian case on this issue is Wenden v Trikha, 1991 CanLII 13111 (AB QB). In Wenden, the court considered whether a hospital and psychiatrist owed a duty of care to persons outside the treatment relationship. While the psychiatrist was not found liable on the facts of that case, the decision established in Canadian law that a mental health practitioner who becomes aware that a patient presents a serious danger to a third party may owe a duty of care to take reasonable steps to protect that person.

The Canadian Psychiatric Association and the CCPA both recognize an ethical and potentially legal obligation to act when a serious and credible threat to an identifiable person is disclosed in a therapeutic context. See the CCPA's Duty to Warn guidance.

Confidentiality and Its Limits

Confidentiality is a foundational principle of therapeutic practice and an important legal protection. However, it is not absolute. In Canadian law and professional codes of ethics, confidentiality may, and in some cases must, be breached in specific circumstances:

  • Where the client presents a credible and imminent risk of serious harm to an identifiable third party (duty to warn / duty to protect).
  • Where the client presents a serious and imminent risk of suicide or serious self-harm that requires emergency intervention.
  • Where a court order requires disclosure of therapeutic records.
  • Where the practitioner has reason to believe another regulated health professional has engaged in sexual abuse of a patient (in provinces where mandatory reporting obligations exist under health professions legislation).
  • Where the client has explicitly authorized disclosure.

The Fiduciary Dimension of Therapy

Beyond the duty of care in negligence, the therapeutic relationship may also carry fiduciary obligations. A fiduciary relationship exists where one party places trust and confidence in another who holds a position of power and undertakes to act in the other's interests. Canadian courts have recognized the therapeutic relationship as having fiduciary characteristics, particularly given the power imbalance inherent in therapy and the vulnerability of clients who disclose intimate personal information.

The significance of the fiduciary framework is most apparent in cases involving boundary violations and sexual misconduct. Where a therapist exploits the trust and intimacy of the therapeutic relationship for their own purposes, a claim may be framed in both negligence and breach of fiduciary duty. Breach of fiduciary duty allows courts to consider the full extent of the harm caused by the exploitation of trust, including harm that may be difficult to frame purely in negligence terms.

Common Grounds for Malpractice Claims Against Psychotherapists and Counsellors

This section provides a detailed examination of the most common causes of legal action against psychotherapists, counsellors, and related practitioners in Canada. Particular emphasis is given to breach of confidentiality and dual relationships and conflicts of interest, which are among the most frequent and underappreciated sources of liability in talk therapy practice.

Sexual Misconduct and Boundary Violations

Sexual misconduct and boundary violations represent the most serious, and most clearly actionable, category of malpractice in the therapeutic context. The power imbalance inherent in therapy, combined with the intimate disclosure of personal material, creates a profound vulnerability in clients. The exploitation of that vulnerability for the practitioner's own purposes constitutes a fundamental breach of professional and ethical duty.

Sexual contact between a therapist and a current client is prohibited without exception in the code of ethics of every regulated mental health profession in Atlantic Canada. Sexual contact with a former client within a specified post-treatment period is also prohibited and, in some provincial codes, prohibited indefinitely.

How these claims arise in practice:

  • Sexual contact or overtly romantic communication during the course of treatment.
  • Gradual “grooming” of the client through increasingly personal, non-clinical communication before physical contact occurs.
  • Sexual communication or solicitation by text, email, or social media.
  • The practitioner “terminating” the therapeutic relationship with the purpose of pursuing a sexual relationship, without a genuine clinical basis for termination.
  • Non-consensual or non-therapeutically justified physical contact during sessions.

Evidence in these cases often includes session notes, text message records, email histories, social media communications, and the testimony of the client. Regulatory college decisions, where a practitioner has already been disciplined, provide powerful supporting evidence in civil proceedings, even though they are not binding on the civil court.

Breach of Confidentiality: When Does a Lawsuit Arise?

Unauthorized disclosure of a client's therapeutic information can cause profound and lasting harm, damage to personal relationships, loss of employment, damage to professional reputation, social harm, and significant psychological distress. A practitioner who discloses confidential information outside the recognized exceptions is exposed to both regulatory discipline and civil liability.

Understanding when confidentiality applies and when it does not is essential for clients evaluating whether they have a claim.

The Core Obligation

All regulated mental health practitioners in Atlantic Canada are bound by statutory and ethical confidentiality obligations. In Nova Scotia, for example, the NSCCT's Code of Ethics requires members to maintain confidentiality of all client information and to disclose such information only with informed consent or where required by law. The CCPA Code of Ethics imposes the same core obligation on its members nationally. Similar obligations apply under the codes governing psychologists and registered social workers in all four Atlantic provinces.

When a Breach Is Actionable

A breach of confidentiality may give rise to a civil lawsuit where:

  • The practitioner disclosed client information to a third party without the client's informed consent and without lawful authority.
  • The disclosure was not covered by any recognized exception (see Section 3).
  • The client suffered actual, demonstrable harm as a result of the disclosure, such as loss of employment, family breakdown, reputational damage, or psychological harm.

Common Scenarios Where Breach of Confidentiality Claims Arise

The following are the most frequent ways in which therapists and counsellors breach confidentiality in practice, and the circumstances most likely to result in a civil claim:

  • Disclosing to family members without consent. This is one of the most frequent forms of breach. Even well-intentioned contact with concerned family members, telling a parent what their adult child disclosed, or confirming to a spouse that a client is attending therapy, is a breach where the client has not authorized it.
  • Discussing cases with colleagues or office staff in ways that allow identification of the client by persons who have no need to know. Even if the client's name is not used, detailed clinical information shared in a small professional community may be sufficient to identify the individual.
  • Sharing beyond what was authorized. If a client provides consent to share a summary with their family doctor, that is not authority to share the full clinical record or sensitive disclosures unrelated to the referral purpose.
  • Disclosing to an employer, insurer, or legal representative in response to a request, without the client's informed consent or a court order authorizing the specific disclosure.
  • Producing records in legal proceedings beyond what is required, for example, failing to oppose an overbroad subpoena or production order that seeks materials the client has a privacy interest in protecting.
  • Social media or informal communication that allows identification of a client. A practitioner who posts about a “difficult case” with enough detail to identify the client, or who discusses clinical material at social events, is breaching confidentiality regardless of whether they name the client.
  • Misdirected or insecure communications, text or email containing clinical material that are sent to the wrong recipient, or that are not stored securely.
  • Disclosure to a client's ex-partner, estranged family member, or other person in a context where the practitioner knows that disclosure may harm the client.

Harm Required for a Civil Claim

A breach of confidentiality is not automatically actionable in all circumstances. For a civil negligence claim to succeed, the plaintiff must establish that the breach caused actual harm. Courts have recognized the following as forms of compensable harm arising from a confidentiality breach:

  • Loss of employment or professional opportunity caused by disclosure of mental health information to an employer or professional body.
  • Relationship breakdown caused by disclosure of sensitive personal information to a partner, family member, or community member.
  • Social or reputational harm in the client's community, workplace, or professional environment.
  • Psychological harm, including exacerbation of the very condition for which the client was seeking treatment, caused by the loss of trust in the therapeutic process or the specific consequences of the disclosure.

Where the breach was deliberate rather than negligent, for example, where a practitioner intentionally disclosed sensitive information in retaliation for a complaint, the conduct may also support a claim for breach of fiduciary duty and potentially aggravated or punitive damages.

Documenting a Confidentiality Breach for Legal Purposes

If you believe your confidentiality was breached:

  • Make a contemporaneous written record of what you know was disclosed, to whom, when, and the specific harm that resulted.
  • Request your complete clinical records, including all intake forms and any signed consent or release documents, these will show what you authorized and what you did not.
  • Request copies of any correspondence between your practitioner and third parties (employers, insurers, legal representatives) in writing.
  • Consult a lawyer. A limitation period applies to these claims (see Section 7), and delay can prejudice your ability to bring a claim.

Dual Relationships and Conflicts of Interest: A Detailed Guide

A dual relationship exists when a practitioner holds more than one kind of relationship with a client simultaneously, for example, treating a friend, neighbour, employee, student, colleague, or business associate. Most professional codes of ethics in Atlantic Canada prohibit or strongly restrict dual relationships because they create conflicts of interest that compromise the objectivity required for effective therapy and that can cause direct harm to the client.

Understanding dual relationships is particularly important for clients in small or rural communities in Atlantic Canada, where the pool of available mental health practitioners is smaller and personal connections between practitioners and potential clients are more common.

Why Dual Relationships Are Prohibited

The therapeutic relationship depends on a clear power dynamic and the client's ability to trust that the practitioner's sole focus is the client's therapeutic wellbeing. When a practitioner also has a personal, financial, or professional relationship with the client, the following risks arise:

  • The practitioner's clinical objectivity may be compromised, they may minimize problems, avoid difficult clinical material, or make clinical decisions based on the personal relationship rather than the client's therapeutic needs.
  • The client may be unable to address certain material freely because they know the practitioner in another context.
  • If the personal relationship deteriorates or creates conflict, the therapeutic relationship is harmed and the client is left without adequate support.
  • The practitioner may inadvertently disclose information shared in therapy into the personal or professional relationship context.

How Negligence Commonly Arises in Dual Relationship Cases

  • Providing therapy to someone with whom the practitioner already has a personal relationship, a friend, neighbour, extended family member, or romantic interest, without disclosing the pre-existing relationship and the risks it creates, and without obtaining the client's genuinely informed consent to proceed.
  • Entering into a business relationship, close friendship, or romantic relationship with a current client during the therapeutic relationship. The CCPA Code of Ethics specifically prohibits sexual or romantic relationships with current clients and imposes strict limitations on relationships with former clients.
  • Providing therapy to multiple members of the same family or social circle without clearly establishing which individual is the identified client, without addressing the inherent conflicts of interest, and without managing the risk that information shared by one client will influence the practitioner's clinical relationship with the other.
  • Accepting gifts of more than nominal value from a client, particularly where the gift creates a sense of obligation or gratitude that could compromise clinical judgment.
  • Entering into financial transactions with a client, lending money, borrowing money, purchasing goods or services, or entering into business arrangements.
  • Using a client's personal disclosures for the practitioner's own benefit, for example, acting on financial information a client shared, or using contacts a client mentioned for the practitioner's own professional networking purposes.

A Recent Canadian Example

In College of Registered Psychotherapists and Registered Mental Health Therapists of Ontario v LeBeau, 2025 ONRPDT 5, a registered psychotherapist was found to have committed professional misconduct after providing therapy to a mother and her child with whom the therapist already had a personal relationship as a family friend and neighbour, without obtaining proper informed consent and without managing the inherent conflict of interest. The panel found breaches of professional standards relating to conflict of interest, dual relationships, and the failure to obtain informed consent to proceed in circumstances where a reasonable practitioner would have declined the referral or terminated the relationship.

While this is an Ontario regulatory decision, the principles it applies are identical to those that govern regulated therapists in Atlantic Canada and reflect the pan-Canadian professional standard.

When a Dual Relationship Claim May Be Actionable

A dual relationship claim is most likely to succeed where:

  • The dual relationship was established without the client's genuine informed consent, that is, the client was not fully informed of the risks the relationship created and did not have a genuine opportunity to seek services elsewhere.
  • The conflict of interest caused identifiable harm to the client, for example, where clinical decisions were made in the practitioner's interest rather than the client's, or where the client's therapeutic progress was compromised by the dynamics of the pre-existing relationship.
  • The practitioner failed to disclose the conflict to their regulatory college or take any steps to manage it through supervision or consultation.
  • The practitioner continued the relationship despite clear warning signs that the dual relationship was harming the therapeutic process.

Failure to Manage Suicide Risk

Failure to appropriately assess, document, and respond to suicide risk is one of the most common grounds for malpractice claims in the mental health context. For psychotherapists and counsellors, who frequently work with clients experiencing depression, trauma, and crisis, this is an area of significant and ongoing liability exposure.

The standard of care does not require practitioners to prevent all suicides. Courts have accepted that suicide risk assessment is inherently uncertain and that a practitioner exercising honest and intelligent clinical judgment, even one that turns out to be wrong, may not be liable. What is required is a documented, structured, and clinically defensible assessment and response process.

How negligence commonly arises:

  • Failing to conduct or document a meaningful suicide risk assessment when a client has disclosed suicidal ideation, stated intent, or a history of attempts.
  • Continuing to provide outpatient counselling for a client whose risk level has escalated to the point of requiring a referral for psychiatric assessment or higher-level care.
  • Using a “no-harm contract” (asking a client to promise not to harm themselves) as a substitute for clinical assessment, this practice is not recognized as an adequate risk management tool.
  • Failing to involve a client's support network or emergency services when a client's risk level warrants it, and failing to document the reasons for the approach taken.
  • Failing to follow up with a client who has missed an appointment after expressing serious ideation.
  • Failing to refer to a physician or psychiatrist when a client's presentation indicates a level of risk that cannot be adequately managed in an outpatient counselling setting.

Documentation is central to defending, and to succeeding on, suicide risk claims. A chart showing no recorded risk assessment in sessions where ideation was discussed is a significant evidentiary problem for a practitioner defending a malpractice claim.

Negligent Use of Therapeutic Techniques

This category covers harm caused by the use of therapeutic methods that are not supported by evidence, applied outside the practitioner's training or competence, or executed incorrectly. It is a growing area of mental health malpractice in Canada and internationally.

Recovered Memory and Suggestive Techniques

The use of hypnosis, guided imagery, or suggestive questioning to “recover” repressed memories of childhood trauma has generated significant litigation in Canada. A CanLII-published academic paper directly addresses the Canadian legal landscape around what was then called “false memory syndrome,” examining the way in which false memories of abuse were being treated in Canadian courts and the liability exposure of therapists who employed suggestive techniques.

Where a therapist employs these techniques without adequate training, uses methods that are known to produce unreliable memories, or actively reinforces a client's developing (and potentially false) narrative of abuse, they may be liable both to the client who has been harmed by the therapeutic process and potentially to third parties who have been falsely accused as a result.

Other High-Risk Technique Failures:

  • Eye Movement Desensitization and Reprocessing (EMDR) administered without proper training, causing retraumatization.
  • Exposure therapy protocols applied without proper preparation, causing severe decompensation.
  • Interventions for dissociative disorders that reinforce rather than integrate dissociated states.
  • Physical touch used as a therapeutic tool outside clearly established, consent-based protocols.
  • Spiritual or religious practices introduced into therapy without consent and without clinical basis.

How negligence is established:

A claim in this category requires expert evidence establishing that the technique used fell below the accepted standard of care, that a competent practitioner with equivalent training would not have employed the technique in the same way, or would not have employed it at all with that patient. The professional standard in Canada requires that practitioners only use techniques within their established area of competence.

Premature Termination and Therapeutic Abandonment

Therapeutic abandonment occurs when a practitioner ends a therapeutic relationship without adequate notice, without facilitating transition to another provider, and in circumstances where the abrupt termination causes harm to the client.

The standard of care requires that a practitioner who ends a therapeutic relationship:

  • Provides reasonable notice where the clinical situation permits.
  • Discusses the termination with the client and explains the reasons for it.
  • Provides referrals or recommendations for ongoing care.
  • Ensures continuity of care for clients with active risk factors, including suicide risk.

Abrupt termination is particularly likely to cause serious harm when the client is in an acute phase of treatment, has an active safety concern, or when the therapeutic relationship itself has been the primary source of stability for a highly vulnerable client.

A practitioner who abruptly terminates a relationship, for example, after learning that the client intends to file a regulatory complaint, or because of the practitioner's own personal circumstances without regard for the client's clinical needs, may be found liable for resulting harm.

Failure to Refer or Consult

A practitioner who continues to treat a client whose condition is beyond their competence, rather than referring to a specialist or consulting with a colleague, may be found to have breached the standard of care.

How negligence commonly arises:

  • Continuing to provide counselling for a client presenting with psychosis, severe bipolar disorder, or major depressive disorder with psychotic features without arranging psychiatric assessment.
  • Failing to refer a client who presents with a level of suicidal ideation or plan that exceeds the capacity of outpatient counselling to manage safely.
  • Treating medical symptoms as purely psychological without referring for investigation of an underlying physical cause.
  • Failing to obtain supervision or consultation when a case becomes complex, deteriorates unexpectedly, or raises clinical questions outside the practitioner's training.

Failure to Warn: Third-Party Harm

Where a client communicates an intention to harm an identifiable person and the threat is serious and credible, the practitioner may have an obligation to take reasonable steps to protect that person. As established in Wenden v Trikha (1991) and developed in subsequent Canadian case law, failure to act on a clearly communicated threat to an identifiable third party, where the harm subsequently materializes, can give rise to a claim by the third-party victim or their family.

How negligence commonly arises:

  • Ignoring explicit verbal threats made in session without documenting them or taking any protective action.
  • Treating a threat as hypothetical or venting without clinical assessment of credibility and imminence.
  • Failing to contact police or the potential victim where the threat was serious and specific.

Misdiagnosis and Failure to Diagnose

While psychotherapists and counsellors generally do not diagnose in the same clinical sense as physicians or psychologists, they may implicitly characterize a client's presentation in a way that shapes the treatment approach. Where a practitioner applies a conceptual framework that is not supported by the client's actual presentation, and where the resulting “treatment” causes harm or delays appropriate care, a claim may be available.

This area overlaps significantly with failure to refer. A practitioner who repeatedly mischaracterizes a client's severe psychiatric symptoms as ordinary stress or adjustment difficulties, rather than recognizing the need for psychiatric assessment, may be liable where the client's condition deteriorates as a result.

How negligence commonly arises:

  • Treating a client for a presentation that is in fact a serious psychiatric condition requiring medical assessment, using counselling techniques that are not appropriate to the actual clinical picture.
  • Failing to recognize or act on indicators that a client's difficulties are medical in origin, for example, symptoms of thyroid dysfunction, neurological conditions, or medication effects, rather than purely psychological.
  • Making informal characterizations of a client's difficulties (for example, as trauma-related or personality-driven) that are recorded in clinical notes and shape subsequent treatment, without the evidence-based assessment required to support them.

Private Practitioner vs. Public Institution: Does It Matter How Your Case Proceeds?

One of the most important and least understood aspects of psychotherapy malpractice law is the difference in how a claim proceeds depending on whether the practitioner worked in private practice or was employed by a publicly funded institution such as a hospital, community health centre, or provincial mental health authority.

The answer is yes, it matters in several meaningful ways.

Suing a Private Therapist or Counsellor

A private practitioner, one who operates an independent practice and is not employed by a public health authority, is personally liable for their own negligence. The claim is brought directly against the individual.

In practice, the practitioner will typically be defended by their professional liability insurer:

  • Registered counselling therapists and registered social workers are required to carry professional liability insurance as a condition of registration in Nova Scotia, New Brunswick, and PEI.
  • Psychologists typically carry professional liability insurance through private insurers or through policies arranged by their provincial college.
  • Unregulated counsellors may carry no professional liability insurance at all.

A practitioner who supervises other practitioners may also be directly liable for the negligence of those they supervise, if the supervisory relationship was close enough that the supervisor should have identified and corrected the problem.

Suing a Public Health Authority or Institution

When a therapist or counsellor is employed by a regional health authority, a publicly funded community mental health program, or a hospital, the claim is typically brought against both the individual practitioner and the employing institution. Health authorities in Atlantic Canada are creatures of provincial statute. Suing them is governed not only by ordinary negligence law but also by the provincial Proceedings Against the Crown Act (or equivalent legislation in each province), which establishes the conditions under which the Crown and Crown agencies can be sued and may impose procedural requirements that do not apply to private defendants.

In all Atlantic provinces, the Crown has waived its common law immunity for tortious acts committed by its servants and agents in the course of their duties. This means a health authority can be sued for the negligence of its employed mental health professionals. However, a distinction exists between “core policy decisions” (generally immune from suit) and “operational decisions” (not immune). A clinical decision made by an individual therapist in the course of delivering care is an operational decision and is not protected.

Vicarious Liability: When the Employer Is Responsible

Under the principle of vicarious liability, an employer can be held liable for the wrongful acts of an employee committed in the course of their employment, even where the employer itself was not directly at fault.

The Supreme Court of Canada's decision in Bazley v Curry, 1999 CanLII 692 (SCC) established that vicarious liability applies where the employer's enterprise materially increased the risk of the harm that occurred. In Bazley, a residential care organization was held liable for sexual abuse committed by an employee because the organization had placed that employee in an intimate position of authority over vulnerable individuals.

The Proceedings Against the Crown

Suing a public health authority involves additional procedural requirements that do not apply to claims against private practitioners. In Atlantic Canada, each province has legislation governing how proceedings against the Crown and Crown agencies must be brought, including requirements around service of documents on specific government officers and, in some provinces, additional notice periods before a claim can be commenced.

Your lawyer must be aware of these requirements. Failure to follow the correct procedural steps can result in a claim being dismissed on technical grounds that have nothing to do with the merits of the underlying negligence.

Practical Differences in Litigation

Records and document production

A public health authority may have far more extensive documentation than a private practitioner, multidisciplinary team notes, incident reports, quality review records, and additional administrative records. This can be an advantage for the plaintiff in establishing what happened, but it also means a more complex discovery process.

Institutional defendants are better resourced

A regional health authority will typically be represented by experienced defence counsel with institutional resources. Cases against public health authorities may involve a more protracted litigation process and a better-funded opposition than cases against an individual private practitioner.

Multiple defendants are common in public institutional cases

A case involving a public mental health program may name the treating therapist, their supervisor, and the institution as co-defendants. Each may take different positions, retain separate counsel, and advance different theories of the case. Managing this complexity requires experienced counsel.

Will a Therapist or Institution Tell Me If Something Went Wrong?

The short answer is not necessarily, and not in the way you might hope for.

In the hospital and public institution context, the Canadian Disclosure Guidelines on disclosure of adverse events apply, and there is a general expectation of candour following adverse outcomes. (These guidelines, originally published by the Canadian Patient Safety Institute, are now maintained by Healthcare Excellence Canada.)

In practice, patients and families in the therapy context face some additional challenges:

  • Mental health outcomes are more difficult to attribute clearly to the actions of one practitioner. A therapist or institution will rarely acknowledge that a client's deterioration, self-harm, or suicide was caused by substandard care.
  • In cases involving sexual misconduct or boundary violations, practitioners almost never self-report. The complaint and the disclosure of what happened comes from the client.
  • In the private therapy context, there is no formal adverse event reporting system. A private therapist who believes they have made an error has no institutional obligation to report it.

You do not need a practitioner or institution to acknowledge fault before protecting your rights. You can:

  • Request all records, notes, and any internal documentation related to your treatment in writing.
  • File a regulatory complaint with the relevant provincial college (listed in Section 2 of this guide).
  • Seek an independent clinical assessment.
  • Consult a medical malpractice or personal injury lawyer.

What Are the Statutes of Limitations for Filing a Psychotherapy Malpractice Claim?

General Limitation Periods in Atlantic Canada

Nova Scotia

The Limitation of Actions Act (SNS 2014, c 35) sets a basic limitation period of 2 years from discovery and an ultimate period of 15 years from the date of the act.

New Brunswick

The Limitation of Actions Act (SNB 2009, c L-8.5) sets a 2-year period from discovery and an ultimate period of 15 years.

Prince Edward Island

The Statute of Limitations (RSPEI 1988, c S-7) sets a 2-year period for personal-injury and negligence claims (s. 2(1)(d); the residual period for other actions is 6 years), with discoverability applied by the courts.

Newfoundland and Labrador

The Limitations Act (SNL 1995, c L-16.1) provides a general 2-year period from discovery.

A studio shot of a sheet reading no evidence no problem
The limitation clock runs from when the harm (and its link to the therapy) was discoverable.

The Discoverability Principle

The limitation clock does not necessarily begin on the date of the harmful event. Under the discoverability principle, time begins to run when the claimant knew or reasonably ought to have known that an injury occurred, that it may have been caused by the practitioner's acts or omissions, and that a legal claim was available.

In psychotherapy cases, this principle is particularly significant because:

  • The harm is often psychological and may not be clearly linked to the therapy until the client has worked with another practitioner and gained perspective on what occurred.
  • In cases involving recovered memory therapy or other suggestive techniques, clients may not recognize for years that they were harmed by the treatment itself rather than helped by it.
  • Clients who were harmed by a practitioner they trusted may remain in the therapeutic relationship well past the point of harm, only recognizing the damage after the relationship has ended.

The date a client first received advice from another clinician, an independent assessment, or a lawyer that what occurred may have been negligent is often treated as the discoverability date.

Suspension for Mental Incapacity

Claims on Behalf of a Deceased Person

Where a client has died as a result of harm connected to negligent therapy, including following a suicide that was the foreseeable result of inadequate risk assessment, a claim may be brought by the deceased's estate or dependants under the applicable provincial legislation. Time limits for estate and dependency claims vary by province and are complex. A lawyer experienced in this area should be consulted promptly.

What Are the Damages and Compensation Amounts Typical for Psychotherapy Malpractice Claims in Canada?

Mental health malpractice claims present particular challenges in quantifying damages. The harm is primarily psychological, and proving its nature, severity, and causal connection to the practitioner's conduct requires careful expert evidence.

Types of Damages

Non-Pecuniary General Damages (Pain, Suffering, and Loss of Enjoyment of Life)

These compensate for psychological pain, emotional suffering, loss of trust, loss of the ability to form healthy relationships, and the reduction in quality of life caused by the practitioner's conduct. In sexual misconduct cases, courts have recognized the profound and lasting harm to a person's capacity for intimacy, trust, and psychological wellbeing.

Cost of Future Therapeutic Treatment

A client harmed by negligent or abusive therapy will typically require significant additional therapeutic treatment to address the harm caused. The reasonable cost of that treatment, psychology, ongoing counselling, psychiatry, is recoverable as a head of damages. In serious cases, particularly those involving sexual abuse within the therapeutic relationship, this can amount to substantial ongoing costs over many years.

Pecuniary Special Damages

These cover actual financial losses including:

  • Lost wages during periods of incapacity caused by the harm.
  • Costs of treatment not covered by provincial health insurance.
  • Costs of legal and regulatory proceedings.

Loss of Income and Earning Capacity

Where the harm caused by the practitioner substantially impairs the client's ability to work, due to worsening psychological symptoms, loss of trust in professional relationships, or significant psychological disability, loss of income and reduced future earning capacity are recoverable.

The Cap on Non-Pecuniary Damages

The Supreme Court of Canada's 1978 damages trilogy (Andrews v Grand & Toy Alberta Ltd.; Thornton v Board of School Trustees; Arnold v Teno) established a cap on non-pecuniary damages for pain and suffering, currently approximately $430,000 to $450,000 in the mid-2020s.

This cap applies to pain and suffering specifically. Future therapy costs, lost income, and other pecuniary losses are not capped. In cases of serious harm from sexual abuse within a therapeutic relationship or from negligent management of a severe mental health crisis, total awards can be significant.

The Particular Challenge of Proving Psychological Harm

Proving psychological harm in a malpractice claim requires more than the client's own account of their suffering. Courts require objective evidence, typically from independent psychiatric or psychological expert witnesses, establishing:

  • The nature and severity of the psychological harm.
  • That the harm was caused or materially worsened by the practitioner's conduct, rather than by the underlying condition for which the client was seeking treatment.
  • The likely trajectory of the harm and the treatment needs it creates.

This causation question, separating the harm caused by the practitioner from the harm that would have existed regardless, given the client's underlying mental health history, is often the central contested issue in psychotherapy malpractice litigation. It is also why expert evidence from qualified mental health professionals is indispensable to these claims.

Contingency Fee Arrangements

Most psychotherapy malpractice claims in Canada are handled on a contingency fee basis, meaning no legal fee is charged unless the case succeeds. Contingency fees in personal injury and malpractice cases in Atlantic Canada typically range from 25% to 33% of the final recovery. The arrangement must be set out in a written agreement.

This means that access to experienced legal representation is not dependent on a client's ability to fund the litigation upfront, a particularly important consideration for clients whose mental health condition and its economic consequences may have already left them in a difficult financial position.

Disbursements and Expert Costs

Psychotherapy malpractice cases require expert evidence from qualified practitioners in the relevant field. Typical disbursements include:

  • Independent psychological or psychiatric expert reports assessing the standard of care (individual reports commonly range from $10,000 to $30,000 or more, depending on scope and specialty).
  • Independent psychiatric assessment of the plaintiff's condition and causation of harm.
  • Psycho-vocational expert evidence in cases involving loss of earning capacity.
  • Medical and therapeutic record retrieval costs.
  • Court filing, discovery transcript, and travel costs.

Most firms working on contingency will advance these costs, to be recovered from the settlement or judgment at the end of the case. Confirm this in writing before retaining counsel.

What Happens If You Lose?

As in all civil litigation in Canada, an unsuccessful party may be ordered to pay a portion of the successful party's costs. This adverse costs risk is a genuine consideration in deciding whether and how to proceed, and a good lawyer will discuss it openly with you at each key decision point.

Thorough expert review before filing is the most important protection against pursuing a claim that cannot be won.

How Long Does a Psychotherapy Malpractice Case Typically Take in Canada?

Psychotherapy malpractice cases are among the more time-consuming civil matters, largely because of the complexity of causation analysis and the expert evidence required to establish both the breach of the standard of care and the harm it caused.

Stages of a Claim

Stage 1: Initial Consultation and Case Evaluation (1 to 3 months)

The lawyer reviews available materials, including any records, correspondence, or notes the client can provide. Some firms engage a mental health consultant for a preliminary opinion before committing to full investigation.

Stage 2: Record Collection and Expert Review (6 to 18 months)

Obtaining complete therapeutic records, session notes, regulatory college records, and any institutional documentation is the foundation of the case. Expert review by a qualified psychologist, psychiatrist, or other specialist is required before a claim is filed.

In sexual misconduct cases, regulatory college proceedings often run parallel to or precede the civil claim, and the findings of a disciplinary panel, while not binding on a civil court, can be powerful supporting evidence.

Stage 3: Issuing the Statement of Claim

Once expert evidence supports the claim, court proceedings are commenced.

Stage 4: Pleadings and Discoveries (1 to 2 years)

Both parties exchange documents and examine witnesses under oath. In these cases, the plaintiff's own mental health history and the question of pre-existing psychological vulnerability are often central areas of examination for the defence.

Stage 5: Mediation and Negotiation (ongoing)

Settlement discussions are most productive after discoveries. The sensitive nature of psychotherapy malpractice cases often means that settlements are preferred by both sides, as trial involves public disclosure of highly personal information.

Stage 6: Trial (if settlement is not reached)

Trials in complex mental health malpractice cases typically run from two to four weeks.

When Settlements Are Most Likely

  • Sexual misconduct cases with strong evidence frequently settle, as defendants and their insurers generally prefer to avoid the public record of trial findings.
  • Suicide cases tend to be more heavily contested, as causation is disputed and defendant practitioners argue that the outcome was not preventable by any reasonable clinical intervention.
  • Cases against public health authorities may be slower to resolve, given the institutional structure of the defendant and the multiple parties often involved.

The Reality of Protracted Litigation

From initial consultation to resolution, a psychotherapy malpractice case will typically take four to seven years. Causation disputes, separating the harm caused by negligence from harm attributable to the underlying condition, are inherently complex and expert-dependent. These are cases where patience, experienced counsel, and realistic expectations are essential.

Things to Consider When Choosing a Lawyer for a Psychotherapy Malpractice Claim

Psychotherapy malpractice is one of the most specialized areas within an already specialized field. The combination of clinical complexity, emotional weight, and the specific regulatory and legal frameworks involved means that not every personal injury or medical malpractice lawyer will have the depth of experience these cases require.

Experience in mental health malpractice specifically

Ask directly whether the lawyer has handled cases involving therapists, counsellors, psychologists, or other non-physician mental health practitioners, and what those outcomes were. The clinical language, the relevant case law, and the expert witness relationships required are distinctive.

Understanding of the regulatory landscape

The patchwork of regulated and unregulated practitioners in Atlantic Canada, and the difference in how claims proceed against each, is not a peripheral issue. Ask whether the lawyer understands which regulatory bodies apply to your practitioner's credential and what role a regulatory complaint might play alongside a civil claim.

Sensitivity to the personal dimensions of these cases

Clients bringing psychotherapy malpractice claims are often in a particularly vulnerable position. The process of re-examining a therapeutic relationship that caused harm, and exposing personal records in the litigation process, is genuinely difficult. The right lawyer will understand this and will handle the process with care, keeping you informed at every step without requiring you to relive traumatic material more than necessary.

Access to qualified expert witnesses

A claim against a psychologist requires a qualified psychologist as the expert. A claim against a counsellor requires expertise in counselling standards of practice. Ask whether the lawyer has established working relationships with credible mental health experts who are willing to review cases and testify.

Written fee agreement

The contingency fee percentage, disbursement terms, and adverse cost risk should all be clearly set out in writing before you sign.
