Death Investigations in Ontario

Common questions about death investigations

What are coroners?
Coroners are medical doctors with specialized death investigation training, who have been appointed to investigate sudden deaths as mandated by the Coroners Act.

What are pathologists and forensic pathologists?
Pathologists are medical doctors who are experts in disease and injury. Forensic pathologists have further training and are experts in disease and injury that result in sudden death. Pathologists and forensic pathologists are the medical doctors who perform autopsies, when required. Forensic pathologists may also be appointed as coroners to investigate cases of suspicious death.

What is a death investigation?
A death investigation is a process whereby a coroner or forensic pathologist seeks to understand how and why a person died. A coroner or forensic pathologist must answer five questions when investigating a death:

  • Who (identity of the deceased)
  • When (date of death)
  • Where (location of death)
  • How (medical cause of death)
  • By what means (natural causes, accident, homicide, suicide or undetermined)

Information may be obtained from several sources including, but not limited to family, co-workers, neighbours, doctors, hospital records, police and other emergency service workers. Contact with family is vital as they often have important information that can aid the investigation.

How are police involved?
Police are usually among the first responders at a death scene. Coroners may request police assistance with investigations.

Why is a coroner called?
A coroner is called to investigate deaths that appear to be from unnatural causes or natural deaths that occur suddenly or unexpectedly. Additionally, a coroner may become involved when concerns are raised regarding the care provided to an individual prior to death.

What is a reportable death?
Certain types of deaths must be reported to a coroner. These reportable deaths include, but are not limited to:

  • deaths that occur suddenly and unexpectedly
  • deaths at a construction or mining site
  • deaths while in police custody or while a person is incarcerated in a correctional facility
  • deaths when the use of force by a police officer, special constable, auxiliary member of a police force or First Nations Constable is the cause of death
  • deaths that appear to be the result of an accident, suicide or homicide

A full explanation of reportable deaths can be found in the Coroners Act.

Who can contact a coroner to report a death?
While deaths are generally reported to the coroner by health care workers or the police, anyone, including a family member, should immediately contact the police and a coroner when a reportable death occurs.

Will a death investigation affect funeral or ceremonial planning?
Funeral or ceremonial planning may be delayed if an autopsy is needed or if the death investigation takes additional time. Coroners and pathologists are aware that religious, spiritual or cultural practices may dictate time frames for funeral planning and other ceremonies or services. In such cases, families should notify the coroner immediately so that every effort can be made to accommodate these requests.

What happens to the body?
In most cases, the family makes arrangements to have the body transported from the place of death to the service provider chosen by the family. In some instances, the coroner will have the body transported to a hospital or forensic pathology unit for further examination, such as an autopsy.


What is an autopsy?
An autopsy, also known as a postmortem examination, is a process whereby a pathologist or forensic pathologist examines the decedent’s body to help determine cause of death. An autopsy usually includes the examination of internal organs.

Who decides whether an autopsy is needed?
The coroner, often in consultation with a forensic pathologist, will decide if an autopsy is needed.

How does a coroner address family concerns about an autopsy?
The coroner will explain the need for an autopsy and carefully assess concerns expressed by the family. However, the coroner will proceed with ordering an autopsy if he or she believes an autopsy is needed to inform the death investigation. The coroner’s decision is legal and binding.

Who performs the autopsy?
A pathologist or forensic pathologist performs the autopsy.

When is organ retention necessary?
In rare circumstances, an organ (usually the brain or heart) may need to be kept after an autopsy for further testing. During the autopsy, small tissue samples may also be kept for additional testing. The coroner will notify the family and ask for their direction about how the organ should be treated after this work is complete.

Can organs or tissues be donated after death?
In cases where a coroner is involved, donation of organs or tissues may be possible. Consenting families should advise the coroner of their wishes.

Obtaining death investigation results

How do families obtain results from the death investigation?
The results of the death investigation can be shared with immediate family members or a personal representative, upon written request. Families may write to the regional office or complete and submit a request form. Forms can be obtained online, by contacting your regional office or by emailing

When can families reasonably expect to receive death investigation reports?
Reports are provided once the death investigation is concluded. The length of time needed to complete an investigation varies depending on its complexity, including the number of tests required. Each death investigation is unique. Family members can contact the investigating coroner or the regional office for an update.

How do families obtain a death certificate?
Only the Office of the Registrar General of Ontario can issue a copy of a death certificate. Please visit ServiceOntario or call 416-325-8305 or toll free 1-800-461-2156 (Ontario only).


What is an inquest?

An inquest is a public hearing designed to focus public attention on the circumstances of a death through an objective examination of facts. At the conclusion of an inquest, the five-person jury often makes useful recommendations that may prevent further deaths.

There are two types of inquests: mandatory (required by law) and discretionary (at the discretion of the coroner).
