Ontario Laboratories Information System

OLIS is a system that connects hospitals, community laboratories, public health laboratories and practitioners to facilitate the secure electronic exchange of laboratory test orders and results.

As a province-wide, integrated repository of tests and results, OLIS will contribute to fundamental improvements in patient care by providing practitioners with timely access to information that is needed at the time of clinical decision making.


Patient Benefits

  • Fewer gaps in information as patients move between hospital, practitioner’s office (e.g. family physicians, specialists), home care and long-term care settings
  • Effective integration and monitoring of laboratory history and treatment progress to support chronic disease management
  • Reduced number of unnecessary laboratory tests due to greater availability and sharing of information
  • Timelier and broader access to laboratory test results by practitioners

Clinician Benefits

  • Timely access to information for improved decision-making at point of care
  • More comprehensive and complete laboratory test information
  • Better coordination of care between multiple practitioners and within health care teams
  • Improved workflow and reduced dependency on paper-based systems


Recent Accomplishments

  • The first phase of OLIS, the foundation adopters program, connected seven foundation adopters – four hospitals (Grey Bruce Health Services, Trillium Health Centre, Lakeridge Health Corporation, and University Health Network), representing 23 hospital sites, and three community laboratories (CML HealthCare Inc., Gamma Dynacare Medical Laboratories, and LifeLabs LP).
  • OLIS has also initiated connections with Alpha Labs and Bio Test Laboratories and is currently receiving their data. Together, OLIS is receiving 96% of community laboratory test data represented by these connections. eHealth Ontario is also connected to Public Health Ontario.
  • Together, all of the organizations contributing data into OLIS represent over 84% of the annual provincial laboratory test volumes.
  • In partnership with OntarioMD, eHealth Ontario has certified 12 electronic medical record (EMR) vendors for access to OLIS data for clinical use. The vendors have completed conformance testing and are in the process of making OLIS data available to their customers through their certified EMRs. Thus far, 9,592 clinicians are engaged in OLIS implementation, of which, 9,030 are successfully connected to OLIS.
  • Health care organizations can currently access OLIS via an OntarioMD certified EMR or a regional solution viewer for the purposes of clinical care. Organizations that do not qualify for either of these channels may quality for OLIS access via our web application, eHealth Services (Lab).
  • All of the initiatives listed above have resulted in approximately 100,000 registered health practitioners having access to OLIS data in support of improved patient care.
  • OLIS has also made technology infrastructure enhancements to improve its operational availability.
  • In July 2015, OLIS initiated its first instance of an electronic Ordering (eOrdering) solution via the Alpha laboratories pilot project. The lessons learned from this pilot project will inform future electronic ordering initiatives across the province.
