Cybersecurity And Financial Audit Compliance 2025 — How To Stay Protected And Audit-Ready

In 2025, CRA and Revenu Québec have introduced stronger cybersecurity audit protocols. Businesses storing digital accounting or payroll data must prove their systems meet encryption, access, and privacy standards. Mackisen CPA Auditors Montreal helps you build a CRA-approved cybersecurity framework that protects your data, prevents fraud, and keeps you fully compliant.

Legal and Regulatory Framework

Personal Information Protection and Electronic Documents Act (PIPEDA): Requires encryption and breach notification for all financial data.
Income Tax Act (Canada) Section 230(1): Mandates secure, verifiable record storage.
Taxation Act (Quebec) Section 1000: Enforces encryption of payroll and QST filing systems.
Cybersecurity Act (Canada, 2024): Establishes federal cybersecurity obligations for all businesses handling tax records.
CRA Policy IC78-10R5: Recognizes encrypted and auditable digital systems as compliant.

Key Court Decisions

Groupe CAVALIER v. Quebec (2021): Found firms liable for payroll data breaches.
Royal Bank v. Canada (2019): Confirmed duty to protect client data under PIPEDA.
R. v. CRA (2020): Gave CRA authority to review cybersecurity policies during audits.

Why CRA and Revenu Québec Enforce Cybersecurity

Both agencies require companies to prove their accounting systems are tamper-proof and encrypted. CRA audits verify cloud and encryption settings, while Revenu Québec examines payroll access controls. Mackisen can assist you with encryption installation, secure backups, and audit documentation so your firm remains compliant and risk-free.
