When a person dies suddenly or unexpectedly, the family is left with questions. Some of those questions are about grief and meaning. Others are about facts. What happened? Was the death preventable? Could the medical care have been better?
The Office of the Chief Coroner of Ontario exists, in significant part, to help answer the second category of question. A coroner’s investigation seeks to determine, in a structured and impartial way, who the deceased was, when and where they died, and how and by what means they died. Where the death occurred in a healthcare setting and the family suspects that negligence or malpractice played a role, the coroner’s involvement can be a critical first step in understanding what happened.
This post is a practical guide for Ontario families in that situation. It explains when the coroner should be notified, what a coroner’s investigation involves, when an inquest may be held, and how the coroner’s findings interact with a potential civil malpractice claim. It does not attempt to replace legal advice or grief counselling. It is meant to give grieving families enough information to make informed decisions in the difficult days that follow a sudden loss.
The Ontario death investigation system
Ontario’s death investigation system is governed by the Coroners Act, R.S.O. 1990, c. C.37. The Office of the Chief Coroner (OCC) and the Ontario Forensic Pathology Service (OFPS) operate together under the Ministry of the Solicitor General. The Chief Coroner directs the system; regional supervising coroners and investigating coroners (typically physicians) perform investigations across the province; forensic pathologists conduct post-mortem examinations.
The coroner’s role is not to determine legal responsibility. The coroner determines facts about the death and makes recommendations directed at preventing similar deaths in the future. Findings of negligence, malpractice, or legal liability are matters for the courts, not the coroner.
When must a coroner be notified
Section 10 of the Coroners Act requires that any person who has reason to believe certain categories of death have occurred must immediately notify a coroner or police. The categories include, among others, deaths that:
- Are the result of violence, misadventure, negligence, misconduct, or malpractice
- Occur as a result of pregnancy or in circumstances reasonably attributable to pregnancy
- Occur suddenly and unexpectedly
- Occur from a disease or sickness for which the deceased was not treated by a legally qualified medical practitioner
- Occur from any cause other than disease
Section 10 imposes the notification duty on “every person.” Healthcare professionals working in hospitals, long-term care homes, and other healthcare settings carry the duty along with everyone else. If a physician or nurse has reason to believe that negligence or malpractice played a role in a patient’s death, they are required by statute to notify the coroner.
In practice, that duty is not always honoured. Where families have any reason to suspect that a death was caused by negligence or malpractice, they should not assume the notification has been made. They can, and should, make the notification themselves.
How to notify the coroner
The Office of the Chief Coroner can be contacted directly:
Office of the Chief Coroner and Forensic Pathology Service 25 Morton Shulman Avenue Toronto, Ontario M3M 0B1
Telephone: 416-314-4000 Toll-free: 1-877-991-9959 (Ontario only) Email: OCC.inquiries@ontario.ca
Notification can be made by telephone or email. Written notification is helpful because it creates a record. The notification should identify the deceased, the location and time of death, and the family’s specific concerns. Where possible, it should be made before any final disposition of the body (burial, cremation, or release for disposition) so that, if an autopsy is needed, the coroner has the option of conducting one.
The investigation
When a coroner is notified of a death within their jurisdiction, they have authority under the Coroners Act to take possession of the body and conduct such investigation as is necessary in the public interest. The investigation is directed at answering the questions set out in section 31 of the Act:
- Who was the deceased?
- When did the deceased die?
- Where did the deceased die?
- How did the deceased die (the medical cause of death)?
- By what means did the deceased die (natural causes, accident, homicide, suicide, or undetermined)?
The investigation may include a post-mortem examination performed by a forensic pathologist, review of medical records, interviews with family members and healthcare providers, scene examinations, and analysis of any other evidence relevant to the death. Depending on the complexity of the case, the investigation may take weeks or months to complete.
The coroner can also investigate a death where there is no body, although the investigation in that situation will be more limited. Section 15(5) of the Act provides for this.
The death review committees
For deaths that occur in healthcare settings and raise patient safety questions, the Office of the Chief Coroner has access to specialized expert committees. These include:
- The Patient Safety Death Review Committee, which reviews deaths where there are concerns about the quality or appropriateness of care provided in a healthcare setting
- The Maternal and Perinatal Death Review Committee, which reviews maternal deaths and perinatal deaths
- The Geriatric and Long-Term Care Death Review Committee, which reviews deaths of older adults in long-term care and similar settings
- The Paediatric Death Review Committee, which reviews paediatric deaths in healthcare and other settings
The committees draw on physicians, nurses, and other healthcare professionals to provide subject-matter expertise to the investigating coroner. The committees do not make findings of legal liability; their role is to identify systemic and individual issues with the care provided, with a view to making recommendations that could prevent similar deaths in the future.
The committee reports are nevertheless valuable in malpractice contexts because they are produced by experienced clinicians reviewing the records in detail and applying current standards of care. Where a family suspects that a death involves a question that falls within the mandate of one of the committees, raising the question with the investigating coroner can prompt a referral.
Inquests
In some cases, the coroner’s investigation will be followed by an inquest. An inquest is a public hearing before a coroner and a jury that examines the circumstances of a death. The jury answers the same five questions set out in section 31 and may make recommendations directed at preventing similar deaths.
Inquests are mandatory in certain categories of death, including most deaths in custody, certain deaths at construction sites, and certain deaths in psychiatric and detention facilities. Outside the mandatory categories, an inquest is discretionary. Family members can request an inquest, and the Chief Coroner will decide whether to hold one based on the public interest in the issues the inquest would examine.
For families pursuing a civil malpractice claim, an inquest can be a significant evidentiary event. Witnesses give evidence under oath. Healthcare providers and institutional representatives may be required to attend. The transcripts and exhibits become part of the public record. The inquest’s recommendations, if any, can shape institutional responses to the issues identified.
That said, inquests are not common in medical malpractice contexts. Most coroner’s investigations of healthcare deaths are concluded without an inquest. Where a family is considering requesting one, legal advice can help in framing the request and in evaluating whether the public-interest threshold is likely to be met.
Using the coroner’s findings in a civil claim
The coroner’s record of investigation, the post-mortem report, and any expert committee report are all potentially admissible as evidence in a civil malpractice trial, but they are not binding on the trial judge. The trial judge will consider the coroner’s evidence alongside all the other evidence in the case and is entitled to reach a different conclusion. The Court of Appeal in Shantry v Warbeck, 2015 ONCA 395, confirmed this framework.
That limitation is significant. The coroner’s role is to determine cause and means of death; it is not to determine legal liability for the death. Even where a coroner concludes that a death was preventable or that better care should have been provided, the trial judge in the civil malpractice action must independently assess whether the care fell below the standard a reasonable practitioner would have met, and whether the breach caused the death.
Within those limits, the coroner’s investigation can nevertheless provide important factual evidence about the cause and circumstances of death. Section 18(7) of the Coroners Act permits family members to receive a copy of the coroner’s record of investigation upon request. The record typically includes:
- The investigating coroner’s findings of fact relating to the circumstances of death
- The post-mortem report
- Reports of any expert committee review
- Toxicology results, if any
- Other documents collected during the investigation
For families considering a civil malpractice claim, the coroner’s record can be a substantial source of information, often before any litigation has begun.
Religious and cultural considerations
For some families, religious or cultural observance requires specific funeral rites, including timely burial or other considerations that may be in tension with an autopsy. These concerns are taken seriously by the Office of the Chief Coroner and can be raised with the investigating coroner. In some cases, alternatives to traditional autopsy (such as imaging-based examinations) may be available. In others, an autopsy will be necessary in the public interest despite the family’s preferences.
Families navigating these considerations should communicate them clearly to the investigating coroner as early as possible, ideally before any decisions are made about the disposition of the body. Where religious or cultural observance is at the centre of the family’s concerns, raising the question early gives the coroner the opportunity to consider accommodations.
Practical decisions for families
The decision whether to involve the coroner usually has to be made in the worst possible moment, in the immediate aftermath of a sudden loss. Families are grieving. They are not, in many cases, focused on the possibility of a future legal claim. Some may feel that involving the coroner is incompatible with the grieving process. Others may simply not know that the option exists.
Some considerations that may help:
- The notification can be made at any time, but the investigation is most effective where it is initiated before final disposition of the body
- If autopsy is a concern, those concerns can be raised with the investigating coroner. The coroner may have options short of full autopsy that would still address the public-interest questions
- The coroner’s investigation is a public interest process. It is not initiated, controlled, or paid for by the family. It does not, by itself, commit the family to any litigation
- Many families later regret not requesting an investigation in cases where they had concerns about the care. The reverse is rare
Where a family has any genuine concern that medical care contributed to a death, the conservative course is usually to notify the coroner. The notification preserves options. It does not foreclose them.
Why this matters
For families. A coroner’s investigation is not a malpractice claim. It is a public-interest process aimed at understanding the cause of death and preventing similar deaths in the future. For families who suspect that medical care contributed to a death, the coroner’s involvement can produce an authoritative factual record at a time when the family is least able to gather one themselves. Where a malpractice claim is later considered, the coroner’s record is a substantial starting point.
For families considering a civil claim. A coroner’s investigation does not establish legal liability and is not binding on a trial judge. But the records it produces (the post-mortem report, the investigating coroner’s findings, the reports of any expert committees) are typically admissible as evidence and can be valuable in establishing the cause of death and the chain of clinical events leading to it. Families pursuing or considering a malpractice claim should request a copy of the coroner’s record as soon as the investigation is concluded.
For healthcare professionals. Section 10 of the Coroners Act imposes a clear notification duty on every person who has reason to believe a death may have been caused by negligence or malpractice. Healthcare professionals carry that duty alongside the rest of the public. Where the question is reasonably open, the conservative course is to notify. The professional’s job is to flag the question for the coroner; the coroner’s job is to investigate.
