Medical Laboratory Professionals

The MLPAO has been representing medical laboratory professionals in Ontario since 1963.

These professionals serve in urban, rural and remote settings in the public and private sectors. Hospitals, physician offices, diagnostic laboratories, clinics, specimen collection sites, blood centers and fertility clinics all require the services of these professionals.


There are just under 600 licensed laboratories and specimen collection centres serving patients across Ontario, with 6,500 practicing Medical Laboratory Technologists (MLTs) and thousands of Medical Laboratory Assistants/Technicians (MLA/Ts).
