Standards of Practice

The Regulated Health Professions Act, 1991 (RHPA) requires each College of self-regulating health care professionals to develop and maintain standards of practice.

These standards outline the level of quality and safety expected for professional services provided to the public by College members.

Legislation, regulations, bylaws, code of ethics, standards of practice, and practice guidelines collectively establish a framework for the practice of medical laboratory science.

The College of Medical Laboratory Technologists of Ontario (CMLTO) Standards of Practice promote the continuing competence of medical laboratory technologists (MLTs) by setting out the expectations of practice against which members can identify opportunities for improvement.
