Cybersecurity Incident

Posted on Thursday November 17, 2022

Peterborough County has been informed by ESO, of a cybersecurity incident on their software which captures patient data. This software is used by Peterborough County/City Paramedics and other paramedic services across Ontario.

The system has been voluntarily and precautionarily shut down and ESO is currently conducting a forensic investigation. While the system is important for many paramedics services, it doesn’t impact our ability to respond to 9-1-1 emergency calls.

“Medical emergency calls to 911 and our front-line service are not directly impacted”, said Peterborough County-City Paramedic Chief Randy Mellow.

Updates will be provided as more information becomes available.
