What Is a Data Breach?
A data breach generally involves unauthorized access to, disclosure of, loss of, or misuse of personal information.
Examples may include:
- hacking or cyberattacks
- ransomware incidents
- employee misconduct
- lost or stolen devices
- accidental disclosure of information
- compromised online accounts
- third-party vendor incidents
Data breaches may create legal, regulatory, contractual, and reputational consequences.
Data Breach Reporting Requirements in Canada
Canadian privacy laws may require organizations to report certain breaches.
This may include obligations under:
- the Personal Information Protection and Electronic Documents Act
- provincial privacy legislation
- health privacy laws
- sector-specific regulatory requirements
Organizations subject to PIPEDA must report breaches involving a “real risk of significant harm.”

Early legal guidance may help preserve privilege and support coordinated response efforts.
