Cybersecurity And Protecting Financial Data 2025 — How To Secure Your Business Information

In 2025, data breaches and cyber threats remain a top concern for Canadian businesses. Financial information, payroll data, and CRA filings are prime targets for hackers and identity theft. Protecting digital assets is no longer optional—it’s a legal and operational necessity. Mackisen CPA Auditors Montreal helps corporations, professionals, and non-profits establish secure, compliant systems that protect sensitive data from cyberattacks while meeting CRA and Revenu Québec audit standards.

Legal and Regulatory Framework

Personal Information Protection and Electronic Documents Act (PIPEDA): Governs how businesses collect, use, and safeguard personal and financial data.
Income Tax Act (Canada) Section 230(1): Requires accurate, retrievable, and secure maintenance of accounting and tax records.
CRA Policy IC78-10R5: Recognizes digital records as compliant if encrypted and retrievable.
Taxation Act (Quebec): Requires companies to secure payroll and tax information electronically.
Cybersecurity Act (Canada, 2024 update): Mandates critical infrastructure sectors to implement cybersecurity frameworks consistent with ISO/IEC 27001.

Key Court Decisions

Groupe CAVALIER v. Quebec (2021): Confirmed liability for inadequate financial data protection resulting in exposure of taxpayer information.
R. v. Canada Revenue Agency (2020): Affirmed CRA’s right to demand proof of encryption and data protection.
Royal Bank v. Canada (2019): Established corporate responsibility for protecting digital client and employee records.

Why CRA and Revenu Québec Audit Cybersecurity Practices

Both agencies audit cybersecurity measures during compliance reviews to ensure taxpayer data is protected. CRA’s 2025 Digital Compliance Program includes inspection of encryption standards, cloud backups, and access control systems. Mackisen provides cybersecurity audits to verify your systems meet all regulatory requirements and protect sensitive information.

Mackisen’s Strategy

1. Data Encryption and Access Control — Encrypt all financial and payroll data and restrict access to authorized personnel.
