Cybersecurity And Financial Data Compliance 2025 — How To Protect Your Business Against Fraud And Data Breaches

In 2025, cybersecurity and data protection are not only technology concerns—they are financial compliance imperatives. CRA and Revenu Québec audits now include cybersecurity reviews to ensure companies protect their financial systems, payroll databases, and client information. A single cyber breach can lead to data theft, identity fraud, and CRA penalties. Mackisen CPA Auditors Montreal provides complete cybersecurity audits, encryption strategies, and compliance systems to keep your financial records secure and auditable.

Personal Information Protection and Electronic Documents Act (PIPEDA): Imposes mandatory security and breach notification requirements for financial data.
Income Tax Act (Canada) Section 230(1): Requires companies to maintain secure, retrievable accounting records.
Taxation Act (Quebec) Section 1000: Enforces encryption standards for payroll and tax filing data.
Cybersecurity Act (Canada, 2024 Update): Sets mandatory standards for accounting and payroll systems used in financial reporting.
CRA Policy IC78-10R5: Confirms CRA acceptance of digital systems only if they include encryption, backups, and traceability.
