The Ontario Laboratories Information System (OLIS) enables hospitals, community laboratories, public health labs and physicians to securely exchange lab test results.

There are many benefits:

  • Timely and complete up-to-date lab information for your care team
  • Less duplication of lab tests
  • Fewer gaps in patient information between the hospital and your family physician
  • If you wish to restrict access to your information on OLIS, please contact Service Ontario at 1-800-291-1405 (TTY 1-800-387-5559)
