OLIS Deployment

OLIS Deployment

What is Ontario Laboratories Information System (OLIS) Deployment?

The Ontario Laboratories Information System (OLIS) gives authorized health care providers access to lab test orders and results from hospitals, community labs and public health labs. As patients move between hospitals, family physicians, home care and long-term care settings, OLIS makes viewing patients' current and past test results easier and enables treatment decisions to be made at the point of care. Clinicians using an OntarioMD-certified electronic medical record (EMR) can access the latest lab results for their patients or perform patient queries in OLIS. 

  • To sign up for OLIS, email
  • Need help with OLIS? Call the Ontario Health Service Desk at 1-888-411-7742 or email 
  • OLIS Deployment is a service provided by OntarioMD on behalf of Ontario Health to connect community-based family physicians,  specialists and nurse practitioners using a certified EMR to OLIS. 

A note on patient consent to access lab results through OLIS: Patient lab results provided through OLIS are considered Personal Health Information. A Health Information Custodian (HIC) can rely on implied consent to access these results when they are part of the patient's circle of care to provide health care to the individual. In some circumstances, patients have the right to restrict/block access to their results. This may restrict the lab results you see. Please visit the Information and Privacy Commissioner of Ontario website for more information.
