Ontario Laboratory Information System (OLIS)

eHealth Ontario is leading the implementation of the Ontario laboratories information system (OLIS) across the province as part of its ehealth strategy.  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 contributes to fundamental improvements in patient care by providing practitioners with timely access to information that is needed at the time of clinical decision making.
