The requesters appealed the Ministry of Revenue's decision to deny access to the estimated 1984 market values of properties in Metropolitan Toronto on a property-by-property basis.
The Ministry claimed the records were exempt under the Freedom of Information and Protection of Privacy Act as personal information and protected by a confidentiality provision in the Assessment Act.
The Commissioner found that while the Assessment Act contained a confidentiality provision, it did not apply to information otherwise publicly accessible on the assessment roll, such as municipal addresses and market values.
Furthermore, the Commissioner determined that the requested information was about properties, not identifiable individuals, and therefore did not constitute personal information.
The Ministry was ordered to disclose the records.
