Paramedic Service Patient Record System Offline 9-1-1 Emergency Calls are not affected

Paramedic services across Ontario have been informed that ESO, the third-party platform used to record patient data has been taken offline in response to unauthorized access.

The Dufferin County Paramedic Service uses the same platform to gather and share information with hospitals about incoming patients. Part of the system is also used for community paramedicine services and other management functions.

This service interruption does not affect the paramedics services ability to respond to 9-1-1 emergency calls.

“Patient care is our top priority,” said Tom Reid, Chief of Dufferin Paramedic Service. “We are still providing services and responding to 9-1-1 calls. We are documenting all our actions locally now until the system is back online.”  

Until further notice, patients under the care of Dufferin County Community Paramedicine Program can confirm or book their appointments by phone at 519-941-0509 or toll free: 1-844-791-1182 or by email at

Cybersecurity experts are supporting the investigation with ESO. There is also no evidence to date that any confidential information has been compromised.

Updates will be shared as they become available.
