Who We Are

The Canadian Society for Medical Laboratory Science (CSMLS) is the national certifying body for medical laboratory technologists and medical laboratory assistants, and the national professional society for Canada's medical laboratory professionals. We are a not-for-profit organization that is funded entirely by membership dues and revenues from goods and services. We do not receive operational funding from governments or other organizations.

Our members practice in hospital laboratories, private medical laboratories, public health laboratories, government laboratories, research and educational institutions. Incorporated in 1937 as the Canadian Society of Laboratory Technologists, the society has over 14,500 members in Canada and in countries around the world.

Our purpose is:

  • To promote and maintain a nationally accepted standard of medical laboratory technology by which other health professionals and the public are assured of effective and economical laboratory services, and
  • To promote, maintain and protect the professional identity and interests of the medical laboratory technologist and of the profession.

One of the major functions of CSMLS is to set qualification standards in medical laboratory science. We conduct exams across Canada and issue certificates to candidates who meet the prescribed standard. CSMLS provides prior learning assessment to internationally educated medical laboratory technologists who are seeking Canadian Certification. The PLA process evaluates an applicant’s academic credentials, language proficiency, clinical training and work experience and their level of competency to write the Certification examination.

Once members are certified, CSMLS provides professional development and continuing education programs to help members update their skills and knowledge, and achieve their professional goals. Our continuing education service provides distance education programs in technical and scientific subjects and laboratory management.
