For families grappling with the immense challenge of caring for a loved one with severe mental illness, the fear of a crisis is ever-present. They provide support, manage medications, and navigate a complex healthcare system, often becoming the front-line caregivers. But what happens when that system fails? When repeated warnings are ignored and a patient’s deteriorating condition leads to a tragic, violent outcome, who is accountable?

This devastating scenario raises a profound legal question: Does a psychiatrist’s duty of care extend beyond their patient to the immediate family members they know are at risk?

For years, the legal answer has been uncertain, often leaning towards protecting the sanctity of the doctor-patient relationship above all else. However, a groundbreaking 2025 decision from the Court of Appeal for Ontario in McKee v. Shahid has challenged this long-held view, opening a new pathway for families seeking justice. This decision signals a critical shift in how our legal system views the responsibilities of mental health professionals, recognizing that the consequences of negligent care often ripple outward, with catastrophic effects on those closest to the patient.

The Duty of Care in Psychiatric Malpractice: A Legal Hurdle for Families

Before any person can be found liable for negligence in Canada, a court must first decide whether they owed a “duty of care” to the person who was harmed. In simple terms, this is a legal obligation to act with a reasonable level of caution and prudence to avoid harming others.

The relationship between a doctor and their patient is a classic example of an established duty of care. It is undisputed that your doctor is legally responsible for providing you with competent medical treatment. However, the situation becomes far more complex when the person who is harmed is not the patient but a “third party”, like a family member.

Historically, courts have been hesitant to extend a doctor’s duty of care to a patient’s family. The primary concern has been the potential for an “impossible conflict of interest.” How can a doctor uphold their primary obligation to act in their patient’s best interests if they must simultaneously consider the interests of the patient’s family, which may be at odds? This legal hurdle has often meant that claims brought by families devastated by a patient’s violent act were dismissed before the evidence could even be heard.

The Tragic Case of the McKee Family: A Preventable Death?

The McKee case brought this legal dilemma into sharp focus. It involved the McKee family, whose 27-year-old son had a long and severe history of addiction and mental health issues. His parents were not distant observers; they were his legal sureties while he was on house arrest and lived with him daily.

As the son’s mental state dangerously deteriorated in the months before the tragedy, his parents grew increasingly desperate. They saw the warning signs: paranoia, delusions, and threats of violence. His parents reached out for professional help, writing letters to their son’s psychiatrists and the treating hospital, Waypoint Centre for Mental Health Care, pleading for him to be admitted for long-term treatment. They believed, correctly, that his life and theirs were in danger.

Despite these direct and urgent pleas, the son was discharged from Waypoint in December 2018, the very same day he was admitted. Two months later, in February 2019, the son stabbed his father to death.

In the aftermath of this unimaginable loss, the mother did what was once considered legally improbable: she sued her son’s two treating psychiatrists, arguing their negligent treatment of her son led directly to her husband’s death.

The Initial Ruling: Why the Court Said Doctors Had No Duty to the Family

The case was initially stopped in its tracks. A Superior Court judge struck down the claim, relying on the classic “conflict of interest” argument. The judge reasoned that imposing a duty on the doctors to protect the parents would conflict with their primary duty to the son.

This reasoning highlights the traditional legal perspective: A doctor must prioritize their patient’s interests, including their right to liberty. Forcing a doctor to also serve the safety interests of the family could, for instance, pressure them to involuntarily commit a patient against their will, infringing on the patient’s rights. Based on this potential conflict, the claim was dismissed without the court ever examining the specific details of the care provided.

A Landmark Appeal: Ontario Court Rules a Psychiatrist’s Duty Can Extend to Family

In a decision that will have lasting implications, the Court of Appeal for Ontario unanimously reversed the lower court’s ruling. The court concluded that the claim was not doomed to fail and deserved to be heard at a full trial. The judges dismantled the “impossible conflict” argument by reframing the entire issue.

1. The Interests Were Aligned, Not in Conflict

The Court of Appeal pointed out that this was not a case of competing interests. The parents were not asking the doctors to prioritize their safety over their son’s well-being. On the contrary, their interests were perfectly aligned. Both the parents and son had the same fundamental need: for the son to receive competent psychiatric care that would treat his illness and prevent him from becoming violent. The lawsuit argued that the doctors failed to meet the standard of care for the son, and it was this failure that resulted in the foreseeable harm to his father.

2. The Harm Was Foreseeable and the Relationship Was “Proximate”

The court determined that the harm to the parents was reasonably foreseeable. More importantly, it found a relationship of sufficient “proximity,” or closeness, to justify a duty of care. The parents were not random members of the public. The doctors knew:

  • The son lived with his parents;
  • His parents were his legal sureties;
  • There was a history of threats and violence towards the parents; and
  • The parents had directly communicated their fears and concerns.

Because of this close and direct connection, the court found it was arguable that the doctors should have had the parents in mind as people who would be directly and catastrophically affected by the quality of the son’s treatment.

3. Speculation is Not a Basis for Dismissal.

The Court emphasized that a claim should not be dismissed based on a speculative or theoretical conflict. Whether an actual conflict existed and whether the doctors’ actions met the professional standard of care are complex questions that can only be answered by examining evidence at a trial. Striking out the claim prematurely denied the family their day in court.

What the McKee Decision Means for Families of a Mentally Ill Patient in Ontario

The McKee v. Shahid decision is a beacon of hope for families who have felt powerless and ignored. It affirms that a mental health professional’s duty may, in certain circumstances, extend to the vulnerable family members they know are in the line of fire.

It is crucial to understand what this decision does and does not mean:

  • It Opens a Door: It allows families in similar tragic situations to bring a claim and have it heard on its merits.
  • It Does Not Guarantee Success: A successful claim will still require proving that the psychiatrist’s care fell below the accepted medical standard and that this negligence directly caused the harm. This requires substantial evidence, typically from medical experts.

These cases remain incredibly complex and emotionally taxing. The legal and medical issues are intricate, and the burden of proof is high.

Steps in a Psychiatric Malpractice Claim

For any family contemplating such a claim, the path forward requires careful and expert guidance. The process generally involves:

  • Comprehensive Record Review: Gathering and analyzing all relevant medical records, clinical notes, and hospital reports.
  • Expert Medical Opinions: Retaining highly qualified psychiatric experts to provide an independent opinion on whether the standard of care was breached. This is the cornerstone of any medical malpractice case.
  • Documenting Communication: Compiling all correspondence, emails, and notes of conversations with healthcare providers that demonstrate knowledge of the risks involved.

A New Era of Accountability in Mental Healthcare

The tragic death of the father in this case was not a random act of violence; it was the culmination of a long and documented mental health crisis. The Court of Appeal’s decision in his family’s case is not about assigning blame or making scapegoats of dedicated medical professionals. It is about ensuring accountability. It recognizes that in the ecosystem of mental healthcare, families are not just bystanders; they are active participants whose safety can depend entirely on the competence of the care being provided to their loved one.
