Online access to COVID-19 lab test results for Health Care Providers

If you are an authorized Ontario health care provider with access to one of the provincial viewers (ClinicalConnect™, ConnectingOntario ClinicalViewer and eHealth Portal) or an electronic medical record system (with OLIS to EMR) or Hospital Information System (with OLIS integration), you can access novel coronavirus (COVID-19) lab test results stored in Ontario Laboratories Information System (OLIS) in near real-time.

Digital Health Immunization Repository Consumer Access Specification – FHIR

To enable the vision of a provincial immunization system where individuals, health care providers, and public health all have real-time access to the same immunization information, Ontario is taking a coordinated approach to facilitate easier collection of, and access to, complete, accurate, and timely immunization records. The goal is to improve health outcomes by making comprehensive immunization information accessible in real time to support health care providers in clinical practice and to engage the public as active partners in managing their health. Key to this approach is the provincial digital health immunization repository (DHIR) – a centralized repository of standardized electronic immunization data which forms the foundation of a broader interoperable ecosystem for immunization data in Ontario. 

The DHIR primarily supports data sharing for public health purposes; Ontario’s 36 public health units access the repository through Panorama. However, the public is also able to access and update their immunization records through a web-based tool called Immunization Connect Ontario/Digital Yellow Card (ICON/DYC).


DHIR Consumer Access FHIR – also known as DHIR Release 4 – built on the FHIR (Fast Healthcare Interoperability Resources ®) standard R4 base specification was designed for consumer application use. DHIR Consumer Access FHIR specifies profiles for the following FHIR resources:

  • Patient
  • Immunization
  • ImmunizationRecommendation
  • RelatedPerson
  • Practitioner
  • Organization
  • Communication

This specification ensures all information technology systems that retrieve immunization data from, and contribute immunization data to, the DHIR can exchange and understand the content through standardized HL7 messages based on FHIR specification and terminologies.


FHIR is an evolving trial-for-use standard, so additional changes by HL7 are expected. We will continue to monitor developments and assess whether or not there are impacts, and publish updates as they emerge.
