TL;DR: Canada’s Bill C-8 shifts critical infrastructure cybersecurity toward continuous, evidence-based resilience rather than periodic compliance checks, according to Horizons.ai’s whitepaper. That changes the practitioner problem from documenting controls to proving exploitable paths are closed and remediation actually holds.
Editorial analysis by NHI Mgmt Group, based on content published by Horizons.ai: “Meeting Canada’s Bill C-8 Cybersecurity Requirements with NodeZero®”.
Key questions
Q: What breaks when critical cyber systems are assessed only periodically?
A: Periodic assessment can miss configuration drift, stale access, and newly exploitable paths that appear after the last review.
Q: Why does Bill C-8 make evidence of control effectiveness more important than documentation?
A: Because the regulatory direction is toward measurable cyber resilience, not just proof that policies exist.
Q: How do security teams measure whether remediation is actually reducing policy risk?
A: Teams should measure whether the share of records at risk is falling over time, not just whether tickets are closing.
Practitioner guidance
- Build continuous validation into critical-system assurance Schedule recurring attack-path tests for the systems and identities that would create the greatest operational impact if compromised, then track whether findings remain closed after remediation.
- Tie IAM and PAM evidence to real exploitability Review privileged accounts, service accounts, and delegated access paths as part of the validation programme so evidence shows whether access can still be abused in practice.
- Include third-party access in the evidence model Test supplier, contractor, and integration access paths alongside internal controls so remediation reporting covers the full critical-system trust boundary.
Bottom line: Bill C-8 pushes critical infrastructure security toward continuous validation, where the question is whether attack paths still work after remediation.

Continuous cyber evidence is becoming the new assurance model for critical systems. Bill C-8 reflects a wider regulatory shift away from control existence and toward control effectiveness. That matters because a policy can be complete while exploitable access paths still exist, especially across identity, cloud, and third-party boundaries. Practitioners should treat evidence of blocked attack paths as a governance deliverable, not an optional technical report.
A question worth separating out:
A: Authentication continuity, least privilege, and access review matter most because recovery is when identity weaknesses become operationally visible. Teams need controls that keep users authenticated, restrict lateral movement, and prove entitlement scope while rebuild work is underway. That is the governance model SOCI is pushing toward.
