No, I don’t think the autopsy report will be made available unless the families decide to release it, which I doubt would happen. Although autopsy reports are a public record, there’s restrictions on who is able to obtain a copy. This is the same throughout Canada. Privacy and confidentially protected through stringent legislation supersede the public’s right to know.

Are Reports from the Investigation Available to the Next of Kin?
Upon completion of the investigation the medical examiner submits a report to the Chief Medical Examiner. This report will normally answer questions about the cause and manner of death, the date, time and place of death and summarize the circumstances surrounding the death. If an autopsy is performed as part of the investigation, the doctor performing the autopsy also submits a report. 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. (An autopsy is an intricate medical procedure, often requiring complex laboratory tests, and for this reason autopsy results may not be available for several weeks after the death. This means the medical examiner's report may not be immediately available to the family.)
The medical examiner's report and the autopsy report may also be requested by attending physicians and medical reports departments of hospitals. Other interested parties, such as an insurer of the life of the deceased or a legal representative of the deceased, may receive the report upon written request and payment of the prescribed fee under The Fatality Inquiries Act.
