Voluntary Roster

Until such time that medical laboratory assistants and technicians are regulated health professionals in Ontario, the CMLTO Voluntary Roster of Registered Medical Laboratory Technicians will serve the public interest by confirming they have voluntarily met a certain level of education and professional practice criteria. On October 1, 2015, the CMLTO launched its Voluntary Roster of Registered Medical Laboratory Technicians.

Each year, every Registered Medical Laboratory Technician is encouraged to maintain an up-to-date CMLTO Professional Portfolio. The Professional Portfolio helps Voluntary Roster affiliates maintain their professional excellence by promoting ongoing self-reflection and development. The Professional Portfolio enables affiliates to set measurable goals toward continuous improvement and enhanced professional practice.

The link to the CMLTO VR Professional Portfolio is emailed to all Voluntary Roster affiliates at the beginning of each year. If you are a CMLTO Voluntary Roster affiliate and did not receive the portfolio link or need further information, please contact CMLTO Registration Department at 416-861-9605 [toll-free in Canada, 1-800-323-9672] ext. 2, or This e-mail address is being protected from spambots.
