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).
