Water Utility Confirms Customer Data Exfiltration, Launches Privacy Remediation Under PIPEDA Oversight

The Challenge

Clearwater Regional Utility, a municipal water provider serving roughly 150,000 residents, experienced a major privacy incident after detecting unusual outbound traffic from its billing network. The investigation revealed that an external contractor account had been compromised due to weak authentication practices. Over the course of several weeks, the attacker exfiltrated customer data including names, addresses, billing histories, and partial payment details. The absence of consistent multi-factor authentication, combined with inconsistent third-party oversight, enabled unauthorized access to sensitive information. The incident triggered public concern, media attention, and immediate scrutiny from the Office of the Privacy Commissioner of Canada (OPC) under PIPEDA.

Our Solution

Our advisory team developed a comprehensive privacy incident response and remediation strategy aligned with PIPEDA and Canadian critical infrastructure requirements. The first step was containment—revoking compromised credentials, rotating encryption keys, and preserving forensic evidence. A structured assessment of the Real Risk of Significant Harm (RROSH) was conducted to guide regulatory notifications and public communication. We coordinated the client’s engagement with the OPC and implemented a 24‑month breach record protocol as required by PIPEDA. Vendor management frameworks were reviewed, third‑party contracts were updated to enforce data protection clauses, and mandatory multi‑factor authentication was established across all external service accounts. Internal governance practices were strengthened through updated policies, revised incident response playbooks, and privacy awareness training.

The Value

The remediation provided measurable value by restoring regulatory compliance and public trust. Clearwater avoided potential enforcement actions through timely reporting and transparency under PIPEDA. Stakeholder communication was proactive and coordinated, reducing misinformation and public backlash. The organization’s improved vendor oversight model reduced future exposure risks by clearly defining accountability between internal teams and service providers. Additionally, the adoption of formal data minimization and encryption controls lowered the probability and impact of future breaches. The incident ultimately became a catalyst for broader cybersecurity maturity across both IT and OT environments.

Implementation Roadmap

1. Immediate containment and forensic preservation of compromised systems and accounts.

2. Execution of PIPEDA-compliant breach notification, including OPC and individual communications.

3. Vendor audit and contractual reinforcement of data protection and multi-factor authentication.

4. Deployment of enhanced encryption, DLP, and continuous monitoring systems.

5. Revision of data retention, privacy, and security governance frameworks.

6. Integration of lessons learned into incident response and risk management programs.

7. Continuous collaboration with CCCS and municipal partners to improve sector resilience.
