The appellant submitted a freedom of information request to the Durham Regional Police Service for records of calls for assistance made in 1965.
The institution denied access on the basis that no responsive records existed.
The appellant appealed, arguing that records should still exist.
The institution provided evidence that records from that era were likely destroyed following the 1974 amalgamation of police departments, and that current retention periods are 15 months.
The Commissioner reviewed the steps taken by the institution to locate the records, including searching historical ledgers, automated systems, microfilm, and contacting a former officer.
The Commissioner concluded that the search was reasonable and upheld the institution's decision.
