Cybersecurity Incident Affects Ontario Court Management System

On June 30, 2026, Thomson Reuters Canada Limited detected unauthorized activity in its C-Track case management platform, which serves Ontario's courts. The incident involved a third party accessing certain court records, potentially including personal information. The Ontario Ministry of the Attorney General was notified on July 23, 2026, and has since collaborated with Thomson Reuters and cybersecurity experts to assess the breach's scope. Although some court records were affected, there is currently no evidence of identity theft or misuse of information. C-Track remains operational, and additional security measures have been implemented to mitigate future risks. Affected individuals are advised to monitor their personal information and may enroll in credit monitoring services offered by TransUnion.

Key Points: • Unauthorized access detected in C-Track, affecting Ontario's court records. • No evidence of identity theft or financial transaction impact reported. • Thomson Reuters and Ontario courts are enhancing security measures.
