Southwestern Ontario hospitals will rebuild network from scratch amid fallout from cyberattack
All five southwestern Ontario hospitals impacted by a cyberattack just over two weeks ago will rebuild their networks from scratch, the hospitals say in an update Wednesday.
But the hospitals also say the investigation into precisely whose data was taken in the attack is expected to take months.
“Through our investigation we know that all our clinical and non-clinical systems were impacted as they are reliant on a safe secure network,” said a statement released by the hospitals’ IT provider, TransForm, and distributed by Windsor Regional Hospital, Hotel-Dieu Grace Healthcare, Erie Shores HealthCare, Bluewater Health and Chatham-Kent Health Alliance.
According to TransForm, their experts have advised them rebuilding the network is the “safest” course of action.
The Oct. 23 attack has been contained — the first of five steps to recovery — but experts are still working on identifying the cause, remediating the network, restoring applications and continued monitoring.
Restoration efforts are “on track” officials said, and restoration for digital patient charting is expected by mid-December — which they said will reduce patient delays. Other applications will come back online approaching mid-December.
The update also specifies specifically which systems are impacted and what records doctors may not be able to access: patient records and history, medication lists, pre-admission work-ups or reports from other professionals involved in patients’ care.

“While some of our systems are functional, they are slower than usual and require extra time,” officials said in a release. “This affects access to labs and diagnostic imaging.”
The hospitals say doctors will cancel procedures if they feel it is unsafe to proceed with some patient information missing. Patients will be rescheduled as soon as possible, the hospitals say.
Residents are also reminded to bring their health card to the hospital when seeking emergency care, and to avoid the hospital except in true emergencies and attend local clinics or their family doctor where possible.
“We want to emphasize to our patients that our physicians and frontline staff are under greater than normal stress due to these unusual circumstances, and they are responding with incredible resolve,” the hospitals said.
“We ask the public for their understanding during this time. This has been a challenging situation for employees, professional staff, patients and families, and we thank our community and system partners for their ongoing patience and support.”
The hospitals also say they have not paid any ransom demanded by the attackers. Earlier this week they released a list of specific information affected by the hack, including information about 5.6 million patient visits at Bluewater Health and the social insurance numbers of more than 1,400 employees at Chatham-Kent Health Alliance.
TransForm has previously said international law enforcement agencies, including Interpol and the FBI, are involved in the criminal investigation. Experts are also working to determine the specific people whose data may have been taken in the attack, and that process is expected to take “a number of months.”
A cybersecurity hotline has been established for patients, available from 8 a.m. to 11 p.m. Monday to Friday at 519-437-6212.
