With a person who dies with a DNR in place - Who provides the death certificate?

Coroners Act
Coroners have the authority to enter and inspect any place where a dead body is located and any place the Coroner has reasonable grounds to believe the body was removed from. It is essential that members understand this aspect of a Coroner’s investigation, and that the scene(s) be preserved until the Coroner has had the opportunity to decide whether he/she needs to attend.
Death scenes shall not be released without the authorization of the Coroner, Death Investigator or Homicide Unit, as applicable
In cases when the body has been transported to a medical facility prior to the Coroner attending the scene of the death, a member shall be designated to attend and remain with the body until directed otherwise. Members shall also be directed to maintain the integrity of the death scene, unless directed otherwise by the Coroner, Death Investigator or Homicide Unit, as applicable
When a Death Investigation does not meet the criteria for a Forensic Identification Officer to attend, the Death Investigator shall record the scene by taking photographs of the deceased and immediate area with a York Regional Police camera. This must be done with permission of the Coroner, as only the Coroner has the authority to grant access to the scene.
When dealing with a non-suspicious death, police act under the authority of the Coroner to conduct their investigations under the Coroners Act. Police powers under criminal investigations are separate and distinct, and police may not use powers under the Coroners Act for a criminal law purpose.
What are the five classifications of death?
- Natural
- Accident
- Suicide
- Homicide
- Undertermined
Natural Death
a death is natural if it is due to a natural disease or known complication thereof; or known complication of treatment for the disease.
Accidental Death
a death is accidental if it is due to an occurrence, incident or event that happens without foresight or expectation. An accidental death is caused by an external factor, where death or harm was not foreseen or expected.
Suicide
a death is considered a suicide when a person kills oneself intentionally. It means that the act was initiated by the deceased and it was non-accidental.
Homicide
the Coroner will define a death as a homicide if it resulted from the action of a human being killed by another human being. The action must be non-accidental and originate from a person other than the deceased. This may include situations where the laying of criminal charges may not seem warranted, such as an altercation in a long-term care facility. Coroners do not use the Criminal Code definition of homicide.
Undetermined
a death is classified as undetermined if a full investigation has shown no evidence for any specific classification; or there is equal evidence or a significant contest between two or more classifications. It also applies if there is insufficient evidence to make a determination, such as in the case of found skeletal remains with no apparent injuries.
