Some files are restricted for 120 years from date of creation to ensure compliance with Ontario’s Personal Health Information Protection Act, 2004 (PHIPA). In cases where the individual has died, if earlier than the 120 year restriction, the restriction period is for 50 years from proven date of death. To request access to restricted files, please submit an application to UHN’s Research Ethics Board using the form and procedures for Application for REB Approval to Access Retrospective Data for Research Purposes or Access for Administrative Purposes. Please see sous-fonds, series and sub-series descriptions and file lists for further details.
