The CMLTO serves the public interest by investigating complaints regarding medical laboratory technologists (MLTs). Following a thorough investigation, the Complaints Committee may refer a matter to the Discipline Committee for a hearing. An MLT who is found, by a panel of the Discipline Committee, to have committed an act of professional misconduct may face fines, suspension and/or revocation of his or her right to practice.

The CMLTO publishes the results of all discipline hearings in its quarterly publication FOCUS, which is available on the CMLTO website.
