Cyber Exposure: The Hidden Deal Risk in Canadian Mergers & Acquisitions

Cyber Risk Is Universal, Not Just for Digital-First Companies

Cyber risk isn’t limited to “digital-first” businesses, every organization is exposed. From a small manufacturer with automated equipment to a law firm housing confidential client files, cyber incidents pose operational and financial threats. Interconnected supply chains and communications mean even modest targets can experience severe fallout. Acquirers must recognize this reality, not just assess data privacy exposure, but gauge whether a target can sustain operations after a cyber disruption.

First-Party Risk: The Critical Vulnerability

While third-party vulnerabilities often grab headlines, first-party risk, internal disruption, can hit hardest. A ransomware breach can bring a company to a standstill: production halts, customer commitments fail, employees scramble, reputations erode. That makes operational resilience a key acquisition metric.

Claim Spotlight: Mid-Size Manufacturing Ransomware (Embroker, Nov 2024)
A mid-sized U.S. manufacturer suffered a ransomware attack via unpatched RDP.

• Business interruption: 5 days, $750K lost
• Ransom demand: $500K
• Recovery & forensics: $300K
• Total claim: $1.55M

Without cyber insurance, buyers inherit these disruptions and costs, on top of integration risks.

Cyber Insurance Gaps: A Blind Spot in M&A

Many SME and mid-market targets in Canada lack cyber insurance, misplaced confidence in traditional liability policies, or neglect coverage altogether. That leaves buyers exposed.

Claim Highlight: JBS Ransomware (Wexford, Nov 2025)
In 2021, JBS’s ransomware shutdown of meat plants led to:

• $11M ransom
• Costs for downtime, forensic analysis, and recovery

Even regulated sectors like healthcare, manufacturing, and finance may skip coverage, despite Marsh reporting over 1,800 cyber claims in 2023 across Canada and the U.S.

Recommendation: If cyber coverage is absent, require it pre-close or embed post-close coverage clauses to transfer risk effectively.

Regulatory Landscape: PIPEDA & Operational Liability

Breach events during or after deal closure can attract scrutiny under PIPEDA, triggering investigations, fines, and litigation, compounding remediation costs. Ongoing reforms may impose stricter compliance obligations, so even legacy vulnerabilities carry future exposure.

Integration Risk: Business Continuity in Transition

Common first-party vulnerabilities include:

• Outdated systems: Mid-market firms often run unsupported systems.
• Transition volatility: Integration phases are peak vulnerability windows.
• Undisclosed incidents: Silence on past breaches transfers hidden risk.
• Fragile response infrastructure: Lack of tested continuity plans prolongs outages.

Insurance Misalignment & Deal Implications

Mismatched policies and run-off provisions often muddle who responds to post-close claims. These misalignments can lead to:

• Indemnity disputes
• Unexpected costs
• Deal litigation

Buyers must analyze both pre- and post-acquisition coverages to avoid exposure gaps.

Best Practices for Canadian Dealmakers

1. Cyber Due Diligence: Evaluate cyber maturity, incident history, security operations, and operational resilience.
2. First-Party Attack Simulation: Stress-test business continuity, escalation processes, and containment plans.
3. Insurance Alignment: Review policies, confirm limits, exclusions, and run-off transitions.
4. Integrate Early: Execute IT/data consolidation with Zero Trust principles and M&A hardening tactics.
5. Governance and Expertise: Ensure board-level oversight and engage cyber risk specialists.

Top 5 Fast Cyber Risk Questions

1. Has the target fully disclosed all past cyber incidents and their handling?
2. Does the target carry cyber insurance, including run-off or tail coverage?
3. How does its cyber maturity compare to industry benchmarks?
4. Have IT/data integration plans been tested to avoid new vulnerabilities?
5. Are regulatory investigations or class actions lurking post-acquisition?

Conclusion

Cyber exposure is no longer a side note in Canadian M&A, it’s a deal-critical issue. Buyers who sidebar cyber risk expose themselves to multi-million-dollar losses, regulatory fallout, and operational setbacks. Those who treat it as a core diligence pillar, embedding resilience, insurance alignment, and integration rigor, preserve value and gain competitive advantage in today’s marketplace..
