Privacy Impact Assessments for Public Sector
Assess and document privacy risks in your programs and systems across Public Sector.
Government departments and public-sector bodies operate under a different privacy framework from the private sector. Federal institutions are governed by the Privacy Act, provincial departments by their own access-to-information and privacy legislation — ATIP statutes, FIPPA-type laws — and municipalities by still more specific local frameworks in some jurisdictions. PIPEDA does not apply. What applies instead are statutory obligations that are older, broader in some respects, and carry explicit public accountability mechanisms that private-sector law does not contemplate.
A Privacy Impact Assessment in the public-sector context is not simply a best practice borrowed from the commercial world. Treasury Board of Canada Secretariat policy instruments require federal institutions to complete PIAs before implementing new or substantially modified programs or activities involving personal information. Provincial governments have issued similar directives. For many public-sector bodies, the PIA is a mandatory governance step — not optional accountability evidence, but a required part of the program lifecycle.
The stakes are proportionate to the scale. Public-sector organizations hold citizen data across taxation, health, social services, licensing, and enforcement. A breach does not affect a single company's customer base — it can affect populations in the tens or hundreds of thousands, and the public trust consequences of that failure are an accountability dimension that simply does not exist in private-sector privacy law. The mandatory breach reporting obligations in most public-sector frameworks, combined with the scrutiny that follows a public incident, make preventive assessment a core organizational interest.
Privacy Horizon conducts PIAs for federal and provincial agencies, Crown corporations, municipalities, and the technology vendors delivering digital services on their behalf. Our work is grounded in the specific legislative framework that applies — not PIPEDA, but the applicable access-to-information and privacy statute for your jurisdiction. We map the data flows across program delivery systems, evaluate risks against the relevant statutory requirements, and produce documentation that satisfies both internal policy requirements and the expectations of your oversight body.
Why Privacy Impact Assessment matters for Public Sector
Public-sector organizations are accountable not just to a regulator but to the public. When a government body fails to protect citizen information, the reputational and institutional consequences extend well beyond the regulatory file. Treasury Board policy instruments and their provincial equivalents treat the PIA as a mandatory governance step before programs involving personal information go live. A well-conducted assessment demonstrates that the public interest in privacy was considered at the design stage — not retrofitted after a complaint or an incident brought the issue to light.
Government departments and public-sector bodies are subject to access-to-information and privacy legislation that governs every stage of the personal information lifecycle — collection, use, disclosure, retention, and disposal — with mandatory breach reporting and public accountability mechanisms. They hold population-scale data assets across health, social services, taxation, and licensing that are high-value targets for both nation-state actors and opportunistic criminals. Public trust is an explicit accountability dimension that does not apply in the private sector.
Relevant frameworks: Federal and provincial access-to-information and privacy legislation (ATIP/FIPPA), Treasury Board of Canada privacy and security policy instruments, ISO 27001, NIST Cybersecurity Framework, SOC 2 Type II (for technology vendors to government)
Our approach for Public Sector
Our assessments are scoped to the applicable legislative framework for your jurisdiction — ATIP and Treasury Board instruments at the federal level, FIPPA-type legislation provincially — and structured around your program delivery model. We map data flows across collection, use, disclosure, retention, and disposal stages, evaluate risks against the statutory requirements that govern each, and produce regulator-ready documentation that satisfies internal policy requirements and withstands scrutiny from your oversight body. Where digital service vendors are involved, we address the third-party accountability obligations that flow through to your department.
