Restricted Title Designation for MLTs

The formal designation of “Medical Laboratory Technologist” or “MLT” is a protected title as defined in the Medical Laboratory Technology Act, 1991 (MLT Act).

The MLT Act states: Restricted titles 9. (1) No person other than a member shall use the title “medical laboratory technologist”, a variation or abbreviation or an equivalent in another language. 1991, c. 28, s. 9 (1). This includes:

  • It is prohibited for anyone who is not a registrant of the College to use the title Medical Laboratory Technologist or any variation of that title, including MLT.
  • Individuals not registered with the CMLTO, including those who have successfully passed medical laboratory science programs or exams, are not authorized to use the title MLT until they are fully registered with the CMLTO or another applicable College.
  • Terms such as “non-registered MLT” or “unregistered MLT” should not be used for those under clinical placement or training under supervision.
  • Any individual holding a position that includes MLT in their job title or description must be registered with the CMLTO first prior to using the restricted title.
  • Employers are strongly encouraged to state in their job offer letters that the Medical Laboratory Technologist position is to be only started upon employees’ registration with the CMLTO.
