Canada’s Cybersecurity Bill C8: What It Means for Critical Infrastructure Operators

Understanding the New Requirements, Risks, and Responsibilities Under the Critical Cyber Systems Protection Act

Canada’s cyber threat landscape continues to evolve-prompting a legislative response that reflects the growing complexity and urgency of the challenge.

On June 18, 2025, the federal government introduced Bill C8, a modernized version of the previously proposed Bill C26, to strengthen cybersecurity protections for Canada’s critical infrastructure. The bill introduces the Critical Cyber Systems Protection Act (CCSPA) and amends the Telecommunications Act, granting federal authorities new powers to manage and enforce national cyber risk oversight.

For leaders in federally regulated sectors, this legislation introduces enforceable obligations and a heightened risk environment. The days of voluntary best practices are over. Cybersecurity is now a matter of compliance, enforcement, and strategic accountability.

Overview of Bill C8

Bill C8 introduces two major legal changes:

1. Critical Cyber Systems Protection Act (CCSPA)

This new act mandates baseline cybersecurity obligations for operators in key federally regulated sectors, including:

• Banking and financial services
• Telecommunications
• Transportation (air, rail, marine)
• Energy (electricity, oil, gas)
• Water and wastewater systems

These entities must identify and secure systems deemed “critical cyber systems,” implement comprehensive cybersecurity programs, and report incidents within government-specified timeframes.

2. Amendments to the Telecommunications Act

The government will have the authority to:

• Direct telecommunications providers to remove or cease using specific equipment or services deemed a national security risk
• Impose security conditions on operating licenses
• Issue directives to mitigate cyber threats in real time

Key Requirements Under the CCSPA

Organizations subject to the CCSPA will be required to:

• Identify and register critical cyber systems
• Implement and maintain a cybersecurity program that includes risk assessments, security controls, and monitoring capabilities
• Report cybersecurity incidents to designated federal authorities
• Respond to and comply with directives issued by the government in the interest of national security
• Conduct ongoing assessments of cybersecurity risks, including third-party and supply chain vulnerabilities

The legislation grants federal regulators oversight, including the ability to audit, monitor, and enforce compliance through penalties and legal action.

Legal and Operational Implications

From Voluntary Frameworks to Legal Obligations

Cybersecurity compliance is no longer optional. Organizations operating in critical infrastructure sectors must meet specific regulatory standards and may face enforcement action for non-compliance.

Increased Government Authority

The Minister of Industry is empowered to issue binding directives and require the removal of technologies deemed risky. While Bill C8 introduces more judicial oversight compared to its predecessor, organizations will still have limited options to challenge urgent national security orders.

Broader Accountability Across the Enterprise

Cybersecurity is now a board-level issue. Legal counsel, procurement officers, compliance teams, and IT departments must all coordinate to meet CCSPA expectations. Accountability for cybersecurity risk now extends far beyond the security team.

Key Differences from Bill C26

Bill C8 incorporates significant updates based on industry and legal feedback:

• Removal of the proposed amendments to the Canada Evidence Act
• Refinement of language to clearly define “interference” and limit overly broad government powers
• Correction of technical enforcement language to clarify compliance mechanisms
• Addition of a formal appeal mechanism for entities that receive government orders
• Enhanced requirements for transparency and judicial review in the event of a government directive

These updates aim to balance the need for security with legal due process and operational clarity.

Recommended Actions for Business Leaders

1. Conduct a Critical Systems Assessment

Organizations must identify all assets and environments that could fall under the scope of “critical cyber systems,” including cloud environments, operational technology (OT), and third-party managed platforms.

2. Perform a Gap Analysis

Evaluate existing cybersecurity controls, governance, and reporting capabilities against the anticipated requirements under the CCSPA.

3. Update Legal, Risk, and Compliance Frameworks

Contracts, vendor agreements, and internal policies must be aligned to reflect new disclosure obligations, information-sharing protocols, and government cooperation mandates.

4. Brief Executive and Board Stakeholders

Ensure the executive team and board are informed of the implications of Bill C8. Cybersecurity must now be treated as a regulated risk with financial, legal, and reputational consequences.

5. Engage Subject Matter Experts

Organizations should work with cybersecurity and legal advisors familiar with regulatory frameworks to develop and implement practical, defensible compliance strategies.

Strategic Perspective

Bill C8 represents a shift in the Canadian cybersecurity landscape. It moves cybersecurity from the domain of best practices and internal controls to one of federally mandated oversight, incident reporting, and supply chain accountability.

It also reflects a broader global trend: governments are no longer assuming that private sector organizations will voluntarily meet the standards required to secure national infrastructure.

This change brings with it new liabilities-but also new opportunities for organizations to strengthen resilience, improve stakeholder trust, and demonstrate leadership in risk governance.
