Cybersecurity And Protecting Financial Data 2025 — How To Comply With Cra Security Standards

Cybersecurity is now a key part of financial compliance. In 2025, both CRA and Revenu Québec expect all businesses to secure their accounting and client data using encryption, strong access controls, and verified cloud storage. Data breaches can trigger financial penalties, audits, and even criminal investigation under federal privacy laws. Mackisen CPA Auditors Montreal helps businesses meet CRA and PIPEDA cybersecurity standards while safeguarding sensitive accounting and payroll information.

Legal and Regulatory Framework

Personal Information Protection and Electronic Documents Act (PIPEDA): Requires all businesses to protect personal and financial data through encryption, limited access, and breach notifications.
Income Tax Act (Canada) Section 230(1): Obligates companies to maintain secure, verifiable electronic records.

Cybersecurity Act (Canada, 2024): Establishes mandatory digital security controls for professional firms handling tax data.
CRA Policy IC78-10R5: Recognizes cloud accounting and encrypted digital records as compliant when verifiable.

Key Court Decisions
