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

Cybersecurity is now a financial necessity. In 2025, CRA and Revenu Québec require businesses to maintain strict data protection measures to secure client, employee, and financial records. A single breach can result in severe penalties, lost trust, and audit exposure. Mackisen CPA Auditors Montreal helps organizations design and implement secure systems that meet CRA, Revenu Québec, and federal privacy standards while protecting financial integrity.

Legal and Regulatory Framework

Personal Information Protection and Electronic Documents Act (PIPEDA): Requires organizations to protect all financial and personal data against unauthorized access.
Income Tax Act (Canada) Section 230(1): Mandates accurate and secure record retention for six years.
Taxation Act (Quebec) Section 1000: Requires data protection for digital financial filings and payroll.
CRA Policy IC78-10R5: Approves electronic storage if systems include encryption, backups, and traceability.
Cybersecurity Act (Canada, 2024 update): Sets national standards for network, cloud, and accounting system protection.

Key Court Decisions

Groupe CAVALIER v. Quebec (2021): Confirmed businesses are liable for privacy breaches of employee tax data.
R. v. CRA (2020): Recognized CRA’s right to audit cybersecurity protocols where taxpayer data is digitally stored.
Royal Bank v. The Queen (2019): Established corporate duty to safeguard financial data from internal and external threats.

Why CRA and Revenu Québec Audit Cybersecurity

Both agencies audit cybersecurity during compliance reviews to confirm that taxpayer data and accounting records are secure. CRA’s 2025 audit protocol includes checks for encryption, backups, and system access logs. Mackisen reviews your data systems to ensure they meet regulatory and technical standards for protection and audit readiness.

Mackisen’s Strategy

5. Staff Training — Educate employees on phishing, malware, and cybersecurity compliance.
