The complainant alleged that Health Canada did not conduct a reasonable search for records in response to two access requests for information related to the personal or designated producers and users of medical cannabis. Responsive records were drawn from a database of medical cannabis producers licensed under the Access to Cannabis for Medical Purposes Regulations (ACMPR). Health Canada acknowledged that there may be additional relevant records stored in a second database but that retrieving this potentially relevant information would be unreasonable. The Office of the Information Commissioner agreed, given the amount of manual labour involved in retrieving additional potentially relevant records.
