Cybersecurity And Cra Compliance 2025 — How To Prevent Data Breaches And Avoid Audit Risks

In 2025, CRA and Revenu Québec have introduced new digital audit standards requiring businesses to demonstrate encryption, system backups, and secure payroll data management. Failing to meet these standards can lead to penalties, data leaks, and potential CRA reassessments. Mackisen CPA Auditors Montreal assists businesses in implementing complete cybersecurity systems tailored to CRA and PIPEDA standards—protecting accounting data and ensuring smooth audits.

Legal and Regulatory Framework

Personal Information Protection and Electronic Documents Act (PIPEDA): Mandates data protection and breach reporting for all financial information.
Income Tax Act (Canada) Section 230(1): Requires businesses to maintain retrievable, secure accounting records.
Taxation Act (Quebec) Section 1000: Enforces encryption for payroll and digital recordkeeping.
Cybersecurity Act (Canada, 2024): Defines mandatory protection standards for tax and financial systems.
CRA Policy IC78-10R5: Approves electronic systems that meet encryption and traceability criteria.

Key Court Decisions

Groupe CAVALIER v. Quebec (2021): Confirmed business liability for unencrypted financial data breaches.
Royal Bank v. Canada (2019): Recognized encryption as a corporate responsibility.
R. v. CRA (2020): Authorized CRA to audit companies’ cybersecurity policies during compliance checks.

Why CRA and Revenu Québec Require Cybersecurity Proof

Auditors now verify encryption, user access controls, and backup integrity during digital compliance reviews. CRA confirms data protection before approving refunds or filings. Revenu Québec cross-checks payroll encryption compliance. Mackisen can assist you with setting up encryption, user management, and real-time data monitoring to prevent non-compliance and financial risk.
