Most deaths in Canada are attended by a physician and do not require any involvement from a coroner or medical examiner. But when a death is unexpected, sudden, unexplained, or occurs in particular circumstances, the process changes. An authority outside the family and outside the medical team takes over responsibility for the body, an investigation begins, and the funeral cannot proceed until that process is complete.
For families navigating this, the situation can feel disorienting. Understanding what these investigations involve, why they happen, what an autopsy is, and what families are entitled to ask for and receive, makes it more possible to navigate the process with some sense of agency.
At a glance
Coroners and medical examiners are responsible for investigating deaths that are unexpected, unexplained, violent, or occur in specific circumstances defined by provincial legislation. They are independent of the police, though the two often work together. An autopsy is a medical examination of the body that a coroner or medical examiner can order as part of an investigation. Their decision to order one is legally binding, even if the family objects. Once an investigation concludes, families have the right to receive the coroner's or medical examiner's report. Timelines vary significantly by province and by the complexity of the case.
The difference between a coroner and a medical examiner
Canada does not have a single national system for investigating deaths. Each province and territory has its own legislation and its own structure. Most use a coroner system, a medical examiner system, or in some cases a combination of both.
Coroners are typically appointed officials who may or may not have medical training. Their role is to investigate the circumstances surrounding a reportable death, determine who died, how they died, when and where they died, and by what means. In some provinces, coroners are lawyers, nurses, or other professionals rather than physicians.
Medical examiners are physicians, typically forensic pathologists, who perform the same investigative function but bring direct medical and forensic expertise to the role. The medical examiner system is used in Alberta, Manitoba, Nova Scotia, and Newfoundland and Labrador. The remaining provinces and territories use a coroner system. Ontario is unique in having coroners who can also act as medical examiners.
The practical difference for families is mainly one of structure. Both systems investigate the same categories of death, produce the same types of reports, and families have broadly similar rights to information in either system.
When a coroner or medical examiner gets involved
Coroners and medical examiners are responsible for investigating and classifying deaths that are unexpected, unexplained, suspected of being violence-related, or believed to be caused by injury or substances. Provincial legislation in each province defines the specific categories of reportable deaths, but they broadly cover the following circumstances:
- A sudden or unexpected death with no attending physician
- A death that occurred by accident, violence, or apparent self-harm
- A death where the cause is unknown or unclear
- A death that may have occurred as a result of negligence
- A death that occurred in custody, including prison, a psychiatric facility, or a youth detention centre
- A death that occurred during or following a medical or surgical procedure in circumstances that raise questions
- A death in a workplace
- A death of a child in circumstances that warrant investigation
- Any death where the circumstances are unusual or unexplained
When a death falls into a reportable category, a physician is not permitted to complete the Medical Certificate of Death. The coroner or medical examiner takes over that responsibility.
It is worth knowing that since 2006, approximately fourteen percent of all deaths in Canada are reported to a coroner or medical examiner annually, resulting in an average of 36,500 investigations each year. Of those investigations, fifty-one percent are ultimately determined to be natural deaths. Involvement of a coroner or medical examiner does not mean the death is considered suspicious. Many investigations conclude that the death was natural and occurred without any wrongdoing.
What happens during an investigation
When a reportable death occurs, the coroner or medical examiner takes temporary custody of the body. They have the authority to examine the scene, collect evidence, review medical records, interview witnesses, and order any examination or analysis they consider necessary, including an autopsy.
The investigation is independent of the police, though coroners and medical examiners often work alongside police when a death may involve criminal conduct. The coroner's role is not to assign criminal responsibility. Their role is to determine the circumstances, cause, and manner of death.
The manner of death is distinct from the cause of death. The cause of death describes what happened medically. The manner of death classifies how the death occurred: natural, accidental, suicide, homicide, or undetermined.
During an active investigation, the family cannot take possession of the body or proceed with funeral arrangements until the coroner or medical examiner releases it. The length of time before release depends on whether an autopsy is required, how complex the investigation is, and whether other agencies are involved simultaneously.
In most straightforward cases, the body is released within one to three days. When an autopsy or toxicology testing is involved, the timeline extends. Families should ask the assigned coroner or medical examiner for an estimated timeline as early as possible so they can plan accordingly.
What an autopsy is
An autopsy, also called a post-mortem examination, is a medical examination of the body after death. It involves the external and internal examination of the body, including organs, tissues, and fluids, to determine the cause of death.
The coroner, often in consultation with a forensic pathologist, decides if an autopsy is needed. The coroner will consider any concerns expressed by the family, but will proceed if they determine it is necessary for the investigation. The coroner's decision is legally binding.
Families cannot legally refuse an autopsy ordered by a coroner or medical examiner, even when it conflicts with religious, cultural, or personal beliefs about the treatment of the body after death. However, families can and should communicate their concerns directly to the assigned coroner. Coroners and pathologists are aware that religious, spiritual, or cultural practices may dictate time frames for funeral planning and other ceremonies. Families should notify the coroner immediately so that every effort can be made to accommodate these requests.
In practice, many coroners will make reasonable accommodations when an autopsy has concluded but the body has not yet been released, and will work to release the body as quickly as possible when a family has cultural or religious obligations that impose time constraints.
An autopsy ordered by a coroner is different from a clinical autopsy, which a hospital may request with family consent to better understand the cause of death when no investigation is involved. The coroner's autopsy is not voluntary and does not require consent. A hospital clinical autopsy does require consent and is declined at the family's discretion.
Toxicology testing, which analyzes bodily fluids and tissues for substances including medications, alcohol, and other compounds, is frequently ordered alongside an autopsy. Results from toxicology testing take longer to process than the autopsy itself, often several weeks, and this can delay the completion of the full investigation.
What families can ask for and receive
Families navigating a coroner or medical examiner investigation are often uncertain about what they are entitled to. The answer is more than many people realize.
Updates during the investigation
Families can ask the assigned coroner or medical examiner for updates on the status of the investigation. The level of detail provided during an active investigation varies, but families should not feel they have no avenue for communication. Most provinces have a dedicated contact at the coroner or medical examiner's office that families can reach with questions.
The coroner's or medical examiner's report
Once an investigation concludes, families have the right to receive the final report. The report documents the coroner's or medical examiner's findings including the identity of the deceased, the cause of death, the manner of death, the circumstances surrounding the death, and where appropriate, recommendations to prevent similar deaths.
In British Columbia, the coroner's report is available to the nearest relative or a person with a valid interest in the findings at no charge. The average timeline for completion of a coroner's report is nine to ten months, though this may vary depending on a number of factors.
In Manitoba, both the medical examiner's report and the autopsy report are available to the adult next of kin upon written request to the Chief Medical Examiner's office.
In Quebec, the coroner's investigation reports are public documents accessible to anyone who requests them, though a special access regime applies to certain confidential documents.
In Ontario, immediate family members or a personal representative can request the death investigation results from the assigned coroner once the investigation is complete.
Families who are unsure of the process in their province should contact the provincial coroner or medical examiner's office directly. Contact information is publicly available.
Requesting an inquest
In most provinces, families can request a coroner's inquest when they have concerns about the circumstances surrounding a death. An inquest is a public hearing at which evidence is heard and a jury makes recommendations. It does not assign criminal liability but can make recommendations to prevent similar deaths.
The Chief Coroner or Chief Medical Examiner decides whether to hold an inquest. In Quebec, in certain situations the Chief Coroner may order a public inquest, after which the coroner files a report outlining the findings and recommendations to avoid similar deaths. The coroner's report from an inquest is public and available to anyone who requests it.
The impact on funeral arrangements
One of the most immediate practical concerns for families is what the investigation means for funeral planning.
The body cannot be transferred to a funeral home or cremated until released by the coroner or medical examiner. When an autopsy is required, cremation cannot proceed until the investigation is complete and the coroner is satisfied that the evidence they need has been obtained. This is because cremation is irreversible and would destroy evidence.
Burial can sometimes proceed before a full investigation is complete, though the coroner must authorize it. Families wishing to proceed with burial should discuss the timing with the assigned coroner.
For families with religious, cultural, or time-sensitive funeral obligations, communicating with the coroner as early as possible is essential. Providing the specific reasons for the time sensitivity, in writing where possible, gives the coroner the best opportunity to respond appropriately.
A note on provincial differences
While the circumstances that trigger a coroner or medical examiner investigation are broadly similar across Canada, the specific legislation, procedures, and rights available to families vary by province. A few differences worth noting:
In Alberta, the Office of the Chief Medical Examiner handles all investigations. Families can contact the office directly with questions and to request reports.
In British Columbia, the BC Coroners Service conducts investigations. Families can request reports online through the BC Coroners Service website.
In Ontario, the Office of the Chief Coroner oversees investigations. Families can request investigation results through the assigned coroner.
In Quebec, the Bureau du coroner is responsible for investigations. Reports are public documents and can be requested from the Bureau.
In Manitoba, the Office of the Chief Medical Examiner conducts investigations. Reports are available to next of kin on written request.
Frequently asked questions
Does a coroner investigation mean the death is being treated as suspicious?
Not necessarily. As noted, the majority of deaths investigated by coroners and medical examiners in Canada are ultimately determined to be natural. Involvement of a coroner or medical examiner means the circumstances of the death fall within a category defined by provincial law as requiring investigation. It does not mean criminal conduct is suspected.
Can a family refuse an autopsy on religious or cultural grounds?
Families cannot legally refuse an autopsy ordered by a coroner or medical examiner. However, communicating religious, cultural, or time-sensitive concerns to the coroner directly and as early as possible gives the best opportunity for those concerns to be accommodated within the investigation process.
How long does it take to get the body released after a coroner investigation?
In straightforward cases where no autopsy is required, the body may be released within one to three days. When an autopsy is required, the process takes longer. The timeline depends on the complexity of the investigation, whether toxicology testing is needed, and the caseload of the office involved. Families should ask the assigned coroner for an estimated timeline as early as possible.
Who pays for the coroner's investigation and autopsy?
The cost of a coroner's investigation and any autopsy ordered by the coroner is covered by the provincial government. Families are not charged for an investigation-related autopsy.
Can a family request their own independent autopsy?
A family cannot conduct an independent autopsy while a coroner's investigation is active. Once the body is released, a family may engage a private forensic pathologist to conduct a second examination if they have concerns about the investigation's findings, though this is done at the family's expense.
How long does a coroner's investigation take?
Timelines vary considerably by province and by the complexity of the case. In British Columbia, the average time to complete a coroner's report is nine to ten months. In other provinces, straightforward investigations may conclude more quickly. Investigations that involve waiting for toxicology results, concurrent criminal investigations, or complex circumstances can take considerably longer.
