Practice guidelines are intended to provide guidance for Ontario’s Medical Laboratory Technologists (MLTs) in their professional practice. 

These guidelines:

  • Are intended to support, not replace, the exercise of professional judgment by MLTs.
  • May be developed by working groups, which may be composed of registrants of the College of Medical Laboratory Technologists of Ontario (CMLTO) or other stakeholders, to ensure they accurately represent best practices and current information.
  • Reflect both public and professional interests.
  • Are maintained by the various CMLTO Statutory Committees.

This page also contains information about interprofessional collaboration which supports MLTs professional practice.

CMLTO White Papers

In 2010 and 2012, the CMLTO developed a set of White Papers and Position Papers that addressed enhancing professionalism amongst MLTs while supporting ongoing collaboration amongst MLTs and other stakeholders and remaining informed about the everchanging healthcare landscape. We strongly encourage you to consult these documents for an understanding of how the CMLTO responds to the evolving needs of the public, the healthcare system, and MLTs.

Empowering Enhanced Professionalism 

Enhanced Professionalism Position Paper


Through the Regulated Health Professions Act, 1991 (RHPA), the provincial government has mandated the regulatory Colleges to promote interprofessional collaboration (IPC) among registrants and with other health profession regulatory Colleges. Through IPC, MLTs may find opportunities to both

  • Share their specialized knowledge with other members of the healthcare team
  • Provide unique value in diagnosis, treatment, and disease management.

IPC is based on the concept that each member of the healthcare team offers a unique value to delivering safe, high-quality patient care. IPC works most effectively when MLTs:

  • demonstrate the impact of their professional practice on patient care
  • focus on excellence in patient care
  • apply and share quality management principles and a process-oriented approach to the health care system
  • develop competencies that support interprofessional collaboration.

The CMLTO Interprofessional Collaboration Infographic was developed by CMLTO staff following a 2022 survey issued to a group of 1000 randomly selected College Practising registrants. The infographic presents findings from the survey and showcases how IPC in MLT practice has evolved over time. The infographic is unique in that it also provides information pertaining to the impact of COVID-19 on MLT practice. For access to this infographic, click here

The CMLTO Quality Assurance Committee approved an updated Collaboration Guideline for MLTs in July 2023. Click here to access the revised document in English, Pour le français, cliquez ici.
