Ministry of Health Electronic Business Services security update
Effective March 23, 2025, the Ministry of Health is installing a new server authentication digital certificate on servers supporting Electronic Business Services (EBS) web services. This includes Medical Claims Electronic Data Transfer (MCEDT) and Health Card Validation (HCV) via EBS. This Technical Bulletin is intended to provide details on the upgrade and the procedures required by vendors.
This will not affect most clients, but further action might be required if any digital certificates (specifically the EBS server digital certificate or any certificates upon which it depends) are installed or configured for your software. The method of updating certificates depends on the software package.
If the EBS server digital certificate is installed into your software, the currently installed version must be removed or replaced.
To ensure continued secure operation, clients should verify that the correct DigiCert certification authority root certificate is installed as a trusted issuer.
