A ransomware attack at Winnipeg’s Health Sciences Centre disrupted facility maintenance systems, including door access, heating, ventilation and air conditioning. Shared Health said patient care and clinical operations remain unaffected, with services continuing normally and no evidence that patients were impacted. Additional security officers were deployed at hospital entrances while affected doors remained unsecured. An investigation is underway to determine the attack’s scope, with provincial authorities and cybersecurity experts notified. The incident follows a 2024 warning from Manitoba’s auditor general that Shared Health needed stronger cybersecurity testing, training and incident-response preparedness.
