Understanding Quebec Law 25 in clinical practice

Law 25 raised the bar for personal data governance in healthcare. Collection and processing must now be clearly justified, transparent, and documented.

In practice, two controls are central: data residency and traceability. Clinics must know where data is hosted, who accessed it, and for which clinical purpose.

Technical safeguards such as encryption, immutable audits, and least-privilege access are no longer optional. They are baseline controls for compliance and risk management.

When a serious-risk incident occurs, response speed matters. A documented protocol can dramatically reduce legal and operational exposure.
