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 from 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) at www.cmlto-onlineservices.com.

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
  6. Any other information deemed relevant
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.
