Privacy Impact Assessments

A privacy impact assessment evaluates a program or information system’s privacy risks and compliance with Ontario’s Personal Health Information Protection Act, 2004Freedom of Information and Protection of Privacy Act and Ontario Health’s Privacy Policy.

Privacy Impact Assessments review issues including:

  • need for program or system
  • personal health information collection
  • data usage
  • consent and notification management
  • data protection measures
  • compliance with Personal Health Information Protection Act, 2004

Assessments focus on new and existing programs or systems. We assess new programs or systems to ensure privacy is considered throughout their design. The privacy assessment may also help determine whether Ontario Health will proceed with development. We assess existing programs or systems to see whether they meet privacy requirements or need revision.

In addition, privacy impact assessments:

  • assess organization-wide practices that could have an impact on privacy
  • address protection safeguards during data collection, transfer and storage, which may include separate analysis of technical security measures and threat risk assessment
  • provide assurance that privacy issues are either resolved or undergoing mitigation
  • promote understanding on how Ontario Health handles personal health information and generate public trust that it is handled responsibly
