Information that has been preserved at the Archives of Ontario after its primary function has expired is used by many people other than those in the original circle of care.

• Sometimes practitioners will draw on old records to understand previous history if a case is reactivated.
• Other users include historians who are studying the history of medicine, as well as those looking at aspects of social history and countless other subjects.
• Authors of fiction also consult archival records to understand a contemporary setting or character for their stories. Margaret Atwood’s Alias Grace is a fictional account of the life of Grace Marks, an early patient of the Queen Street psychiatric hospital. The hospital index card for Grace Marks can be seen here.
• Former patients have come to the Archives of Ontario to look at their own case files to understand and gain meaning from their past.
• Genealogists who are researching their relatives sometimes find valuable information in physicians’ papers or psychiatric hospital records.

This admission form to the psychiatric hospital in Toronto in 1864 provides the age, occupation, place of birth, place of residence, and other details about the patient.

We can sympathize with the supposed “cause of the present attack” stated here as “Loss of wife, failure in business, & disappointment in love.”

Institutions such as the provincial psychiatric hospitals were communities where some patients stayed for many years. Mental illness in the family was often considered shameful and not discussed, so these records may be the only source of family information for later generations.

Health records have been used as evidence to support litigation or claims for compensation, and in the context of provincial inquiries.

or example many individuals and organizations in the health care field were among those who provided records to the Walkerton Inquiry, including the local Board of Health, Ministry of Health, and others. The Archives of Ontario was also those called upon to provide information. It now holds the records of the Walkerton Inquiry and makes them available for public access.

Medical researchers use archival records to study topics such as disease patterns and the effect of treatments over time. Those researching the relationship between genetics and disease try to establish a detailed family history documenting the mental and physical health of all blood relatives in the family tree. This methodology is being used in the research on hereditary factors and schizophrenia.

Policy makers and legislators use health information in order to make informed choices regarding plans and decisions about all aspects of our health care system. For example, statutes and regulations about health and safety issues are introduced following research and analysis of medical and other records.

Medical records are sometimes used in teaching, so that practitioners-in-training can learn from the work of others or gain knowledge about the history of the health care professions. The Archives has a collection of historical records from Ontario pharmacies that was used by the University of Toronto’s Faculty of Pharmacy. It includes pharmacy prescriptions, recipe books, medical almanacs, and other material.
