Cybersecurity And Protecting Financial Data 2025

As cyberattacks rise across Canada, protecting financial and tax data has become a legal and operational requirement. In 2025, CRA and Revenu Québec expect every business to adopt strict cybersecurity measures to protect accounting systems, client data, and payroll information. Mackisen CPA Auditors Montreal helps companies strengthen their data protection infrastructure, ensuring full compliance with federal and provincial standards while safeguarding financial integrity.

Legal and Regulatory Framework

Personal Information Protection and Electronic Documents Act (PIPEDA): Requires organizations to protect personal and financial data from unauthorized access or misuse.
Income Tax Act (Canada) Section 230(1): Mandates that businesses maintain secure, verifiable accounting and tax records.
Taxation Act (Quebec) Section 1000: Establishes security and privacy rules for electronic payroll and tax filings.
Cybersecurity Act (Canada, 2024 update): Sets baseline data protection standards for all financial and professional service providers.

Key Court Decisions

Groupe CAVALIER v. Quebec (2021): Found businesses liable for insufficient protection of tax-related data.
Royal Bank v. Canada (2019): Reinforced corporate accountability for financial data breaches.
R. v. CRA (2020): Affirmed CRA’s authority to inspect cybersecurity systems for compliance.

Why CRA and Revenu Québec Audit Cybersecurity

Both agencies now perform cybersecurity reviews during tax audits to ensure encrypted records and secure data transfer. CRA requires encrypted cloud systems with access logs and multi-factor authentication. Mackisen conducts cybersecurity audits and implements encrypted storage and user-control systems aligned with these requirements.

Mackisen’s Strategy

1. Cybersecurity Assessment — Identify vulnerabilities in accounting and tax systems.

2. Encryption & Access Control — Apply bank-grade encryption and role-based user permissions.

3. Secure Cloud Integration — Configure CRA-approved cloud systems with daily backups.

4. Staff Training — Educate employees on phishing and fraud prevention.

5. Incident Response Plan — Develop data recovery and reporting protocols under PIPEDA.

Real Client Experience
