Registration Classes

The Medical Laboratory Technology Act, 1991, governs the profession of medical laboratory technology, and under Ontario Regulation 207/94 defines the registration categories for CMLTO members.

There are two classes of registration with the CMLTO:

  • Practising – Members have met all the requirements of the CMLTO (education, examination, active engagement in the profession) and are able to practise without restriction.
  • Non-practising – Members have met the CMLTO registration requirements, but are not permitted to practise.

For detailed information about registration requirements for both classes, click here (PDF).
For information about changing registration class, click here.

To request a change in registration class from Non-Practising to Practising, complete and submit the Changing Classes of Registration from Non-Practising to Practising - PDF  form. For further information, contact CMLTO Registration at 416-861-9605 [toll-free in Canada, 1-800-323-9672] ext. 1, or This e-mail address is being protected from spambots.
