Cybersecurity And Financial Data Protection 2025 — How To Ensure Your Business Is Audit-Proof

In 2025, cyberattacks and data leaks continue to target accounting and payroll systems across Canada. CRA and Revenu Québec now include cybersecurity verification as part of their audit and compliance protocols. Businesses that fail to meet encryption, access control, and data retention standards face potential fines and liability for breach of confidential financial data. Mackisen CPA Auditors Montreal helps businesses establish secure digital infrastructures, ensuring that all financial data, payroll systems, and CRA submissions are fully protected and compliant.

Legal and Regulatory Framework

Personal Information Protection and Electronic Documents Act (PIPEDA): Governs how businesses collect, protect, and disclose financial data.
Income Tax Act (Canada) Section 230(1): Requires all accounting records to be protected and retrievable in secure formats.
Taxation Act (Quebec) Section 1000: Mandates encryption for electronic records used for tax and payroll filings.
Cybersecurity Act (Canada, 2024): Sets technical standards for data protection across professional financial systems.
CRA Policy IC78-10R5: Recognizes electronic records and cloud-based accounting as compliant when secured by encryption and traceability.

Key Court Decisions

Groupe CAVALIER v. Quebec (2021): Found companies financially liable for payroll data breaches under PIPEDA.
R. v. CRA (2020): Upheld CRA’s authority to inspect corporate cybersecurity systems during audits.
Royal Bank v. Canada (2019): Confirmed the obligation of firms to implement security and encryption protocols for customer financial information.

Why CRA and Revenu Québec Audit Cybersecurity Controls

Tax authorities now assess cybersecurity during audits to ensure financial records are not exposed to theft or tampering. CRA checks encryption and data backup systems, while Revenu Québec verifies payroll data security. Mackisen CPA Auditors Montreal builds and certifies compliant cybersecurity frameworks tailored for financial recordkeeping and audit readiness.
