PIPEDA Report of Findings #2018-003: Facebook agrees to stop using non-users’ personal information in users’ address books
The Office of the Privacy Commissioner of Canada investigated a complaint against Facebook Inc. regarding a privacy breach where personal information of users and non-users was inadvertently disclosed through the 'Download Your Information' tool. The investigation found that while Facebook had safeguards in place, they were not adequate prior to the breach, leading to the unauthorized disclosure of contact information. Additionally, Facebook was not sufficiently open about its practice of matching contact information across address books. Facebook has since implemented corrective measures, including a new Privacy Framework and revised notices, resolving the issues.
