Threat & Risk Assessment Services in Ontario
Identify, prioritize, and act on security risks across your organization in Ontario.
Ontario is home to some of Canada's most densely connected commercial infrastructure — financial services firms, technology companies, healthcare networks, and professional services organizations that handle large volumes of sensitive data daily. That concentration of activity is a business strength and a security target. The incidents that make the news are rarely random; they reflect threat actors who have already done their reconnaissance and found the gaps an organization didn't know it had.
A Threat and Risk Assessment is the disciplined process of finding those gaps yourself, on your own timeline, before an attacker does. Privacy Horizon works with Ontario organizations to build a complete picture of security risk: identifying the assets and data that matter most, mapping credible threats against your specific operating environment, and conducting a rigorous vulnerability analysis that covers technical controls, access management, and the human and process factors that shape real-world exposure.
What comes out of that work is a risk register ranked by the combination of likelihood and impact — not a theoretical threat catalogue, but a prioritized list of what to address first, second, and third, matched to a remediation roadmap that reflects your organization's capacity and risk tolerance. The goal is clarity and forward motion, not a deliverable that sits in a folder.
Ontario commercial activity is governed by federal PIPEDA, with enforcement by the Office of the Privacy Commissioner of Canada. For organizations that handle personal health information — hospitals, clinics, pharmacies, and other defined health information custodians — PHIPA adds a parallel set of obligations overseen by the Information and Privacy Commissioner of Ontario. In both frameworks, a security incident that exposes personal information carries mandatory notification consequences: to individuals, and in the case of PHIPA, to the IPC as well. A TRA doesn't just reduce the likelihood of an incident — it reduces the downstream exposure that a breach would create, making it one of the most practical investments an Ontario organization can make in its security and compliance posture.
Privacy & security regulation in Ontario
Regulator: Information and Privacy Commissioner of Ontario (IPC)
Ontario organizations operate under federal PIPEDA for commercial activity, with health-sector custodians additionally governed by PHIPA and overseen by the Information and Privacy Commissioner of Ontario.
PIPEDAPersonal Information Protection and Electronic Documents Act
PIPEDA is Canada's federal private-sector privacy law. It sets out ten fair information principles governing how organizations collect, use, and disclose personal information in the course of commercial activity. It applies wherever a province has not enacted substantially similar legislation — and, even in provinces that have (Alberta, British Columbia, Québec), it continues to apply to federally regulated businesses such as banks, airlines, and telecommunications, and to personal information that flows across provincial or national borders.
PHIPAPersonal Health Information Protection Act, 2004
PHIPA governs how health information custodians in Ontario — a defined, closed list of providers such as hospitals, physicians, and pharmacies — collect, use, and disclose personal health information. It establishes consent rules and individual access rights, and requires custodians to notify affected individuals at the first reasonable opportunity following a breach, and to report to the Information and Privacy Commissioner of Ontario in the circumstances the Act prescribes.
What Threat & Risk Assessment includes
A threat and risk assessment (TRA) gives you a clear, prioritized view of where your security risks are and what to do about them first.
Asset & Threat Identification
Map what you're protecting and what threatens it.
Vulnerability Analysis
Find the weaknesses that matter most.
Risk Prioritization
Rank risks by likelihood and impact, not guesswork.
Remediation Roadmap
A practical plan to reduce risk in priority order.
Protecting Health Data and Commercial Data Equally
Ontario's dual-layer framework — PIPEDA for commercial activity and PHIPA for health information custodians — means that organizations in the health sector face two distinct breach-notification regimes simultaneously. A TRA maps your data assets against both, identifying where a single security failure could trigger obligations under each law. That kind of cross-framework visibility is particularly valuable for health-tech companies, digital health platforms, and providers that sit at the intersection of both.
Sequenced Remediation for Complex Environments
Large Ontario organizations often have years of accumulated technical debt — legacy systems, overlapping access controls, and third-party integrations added faster than they were documented. Our remediation roadmap doesn't assume a clean slate. It sequences fixes by risk level and complexity, so your team can make meaningful progress without shutting down operations, and so leadership has a defensible record of due diligence throughout.
