Labour Mobility

Provincial governments are committed to ensuring professionals regulated in one jurisdiction can become registered in any other jurisdiction in Canada. Where the profession is regulated, medical laboratory technologists (MLTs) are included among the professionals that now enjoy full labour mobility.

An MLT with a current Practising certificate of registration in a regulated province (Alberta, Manitoba, New Brunswick, Newfoundland, Nova Scotia, Prince Edward Island, Quebec or Saskatchewan) may apply for registration with the College of Medical Laboratory Technologists of Ontario (CMLTO) as a labour mobility applicant.

Also, as of July 24, 2023, medical laboratory technologists registered in another Canadian province or territory may start working in Ontario if they are in good standing with their current regulatory body (i.e., no professional conduct or registration concerns) and must have completed a CMLTO application including payment of the application assessment fee. For more information, please refer to the Registration Committee Policy 23: Applicants Registered in a Canadian-Regulated Jurisdiction available here / Demandeurs inscrits dans une administration sous réglementation Canadienne ici.

CMLTO LETTER OF STANDING

Health regulatory colleges will require a Letter of Standing from applicants who are registered in the health profession in another jurisdiction.

A Letter of Standing will include the following information:

  1. Registrant’s name and license number
  2. Date of initial registration
  3. Registration history, class and specialties
  4. A description of registration held, including any terms, conditions, and limitations
  5. Ongoing investigation, allegation, conviction, suspension, and discipline hearings

If other regulators request further information about a CMLTO Letter of Standing regarding one of its registrants, the CMLTO has the legal authority to share relevant information based on section 36(1)(c) of the Regulated Health Professions Act, 1991 (RHPA). By requesting a Letter of Standing to be sent to the other regulator, the registrant is in effect acknowledging and consenting to the CMLTO to send all relevant information to the other regulator. For more information, please review Registration Committee Policy 19: Letter of Standing available here, Lettre d’attestation en français ici
