Canadian departments take websites offline after global PHP vulnerability; officials report no sign of data compromise
Published · Updated
What happened
The Government of Canada temporarily took multiple websites offline and began patching affected systems after a global PHP security issue prompted concerns about exposure. Federal officials told Global News they had no indication that Canadian government systems or information holdings had been compromised.
Why it matters
This is an active cyber-defence and service-continuity event affecting federal digital operations. Even without confirmed data loss, precautionary shutdowns and ongoing patching can interrupt public access, delay departmental workflows, and test incident coordination across shared and department-run systems.
Federal officials said there was no indication Canadian government systems or information holdings had been compromised by a globally exploited PHP vulnerability, after several Government of Canada websites were taken offline as a precaution. Departments are patching systems and restoring services while the vulnerability remains active internationally. The immediate issue for Ottawa is continuity of public-facing digital services and whether additional defensive measures are needed across federal infrastructure.
