DNR Validity in Suicide

In Ontario, a valid DNR (Do Not Resuscitate) form does NOT apply in the context of a suicide attempt. This is because suicide is generally considered a result of a mental health crisis, which invalidates prior consent decisions due to impaired capacity.

Even if paramedics are presented with a completed MOH DNR form at the scene of a suspected suicide, they are still expected to intervene and provide life-saving care. The DNR standard only applies when:

• The patient is not suffering from a self-inflicted injury.
• The MOH DNR Confirmation Form is fully completed and presented (handwritten notes are not valid).
• The person is not showing signs of life and death appears natural or expected.

Advance directives and the wishes of substitute decision-makers (SDMs) do not override this obligation in suicide scenarios, as doing so could potentially violate the Criminal Code (e.g., aiding or abetting suicide).

In most cases, a suicide attempt voids the legal and ethical validity of a DNR, and paramedics are required to proceed with resuscitation.
