Keeping your information updated is a professional obligation

Reviewing and updating your information through CMLTO online services is not only required during the registration renewal period. Access your profile at any time to make updates. In fact, MLTs are required by law, to update the following information within 30 days of any changes:

  • Name
  • Email address
  • Home address and telephone number
  • Name, address, and phone number of each current employer
  • Job titles.

Registrants must inform the CMLTO if they have been charged with, or found guilty of, an offence and the report must include information about every bail condition or other restriction imposed on them. This report must be made as soon as possible (i.e., no more than 10 days) after the charge is laid. Registrants cannot wait until renewal time to report such a charge. They must report that information to the College by email to This e-mail address is being protected from spambots. You need JavaScript enabled to view it .

Please remember to update your information through CMLTO online services when changes occur. It can be done easily from any computer or device, 24/7 year-round.

Guidelines for evaluating professional practice activities

Professional Practice staff launched a new practice resource (PDF) for registrants and other laboratory stakeholders to assist them in answering the question: “Can I or am I allowed to do this activity?”

The guideline:

  • uses a 4-step framework to break down complex concepts into actionable processes

  • prompts stakeholders to ask important questions

  • contains an appendix that provides specific examples.

Interested in learning more? Join our webinar on January 27, 2022, from 12:00 – 12:45 pm where Professional Practice staff will provide an overview of the guideline and provide examples of applying it within MLT practice. For those who cannot attend the live session, the webinar will be recorded and posted on the CMLTO website. Click here to register for the live event.
