Refresher Courses

The CMLTO provides a list of approved refresher courses at the bottom of this page.
Refresher course hours may be required for a person applying for a Practising class of registration certificate who cannot demonstrate active engagement, or for a Non-practising registrant who wishes to change class to Practising. 

The completion of refresher courses must be within the three years preceding the application.

The required number of refresher course hours depends on the number of years a registrant or applicant has been away from the medical laboratory technology profession.

An individual applying for registration with the CMLTO, or a registrant upgrading from a Non-Practising to a Practising certificate of registration may request that courses that DO NOT appear on the CMLTO approved refresher course lists be considered toward their active engagement registration requirement.
This form (PDF) is to be used for courses that DO NOT appear on the CMLTO approved refresher course lists, but HAVE BEEN TAKEN from one of the following organizations:

- The Michener Institute for Education at UHN
- Canadian Society of Medical Laboratory Science
- LabCE

Please submit a separate form for EACH refresher course. Send this form to the Registration Department, along with the guarantor-signed proof of completion and completed Guarantor’s verification form/Ligne directrice sur les soumissions à l’OTLMO, by following the current CMLTO submission guideline.

One or more courses may be taken to achieve the required number of hours.
The standard number of required hours is 90, though some of these hours may be exempted for those who have been away from the profession for less than six years. The following chart outlines the requirements.

Other courses may be submitted to the CMLTO Registration Committee for consideration for approval prior to enrollment in the course (the course must have an evaluation component and be related to medical laboratory science).
