CSMLS Exam Dates 2026-2027: Registration Deadlines, Fees and Results

CSMLS (the Canadian Society for Medical Laboratory Science) runs certification exams for General Medical Laboratory Technologists (MLT) and Medical Laboratory Assistants (MLA). For 2027 it has published three exam sessions: 22 to 26 February, 21 to 26 June and 25 to 29 October. Registration for the February 2027 session opened on 15 October 2026 and closes on 30 November 2026; late registration runs 1 to 15 December 2026 at a higher fee.

Two things changed in 2026. CSMLS says that as of 1 March 2026 its General MLT exam is written only in the province of Alberta: the October 2026 handbook says all General MLT exams must be written in Alberta, and the dates page marks the General MLT sessions "Open to Alberta Residents only" (the handbook also lets CMLTA give permission to some candidates who live elsewhere). And CSMLS has set an end date: the October 2028 session is the last General MLT exam, and the handbook says CSMLS General MLT exam services will be discontinued on 1 January 2029. The MLA exam stays open across Canada.

ProSyllabus is an independent study site. It is not part of CSMLS (the Canadian Society for Medical Laboratory Science), CMLTA or CAMLPR, and nothing here is the official exam. Every date, fee and rule on this page is taken from the official pages listed at the foot of the page.

CSMLS lists the 2027 sessions under "MLA (all of Canada) and General MLT (Alberta only)". You book a seat for one day inside the session.

If you need an accommodation, CSMLS says not to register online: contact exam@csmls.org for the steps and forms, because a request from someone who has already registered online will not be considered.

In 2026 CSMLS ran four sessions. The General MLT exam was in three of them; the August session was MLA only. The dates page marks the 2026 General MLT sessions as open to Alberta residents only.

All fees are in Canadian dollars and must be paid in Canadian funds. The late fee replaces the regular fee; CSMLS shows the difference in brackets. Late registration fees are not reimbursed, including for deferrals, extensions or cancellations.

CSMLS counts "exam date" here as the first date of the exam session.

The October 2026 handbook describes CSMLS as the Alberta certifying body for General MLTs, providing exam services on behalf of the College of Medical Laboratory Technologists of Alberta (CMLTA). The Exam Eligibility page lists two ways to become eligible for the first time:

The handbook also lists candidates given permission by CMLTA to attend a CSMLS General MLT session, for example program graduates or internationally educated technologists who live outside Alberta. It says all General MLT exams must be written in Alberta whatever the testing method, and that non-residents of Canada can only write at a test centre in Alberta.

From the October 2026 session, General MLT candidates have four attempts in two cycles. The first cycle is one attempt, to be taken within 12 months of becoming eligible. After an unsuccessful first attempt you have three more, to be taken within three years or by the October 2028 session, whichever comes first.

A missed appointment counts against you: CSMLS says a candidate who arrives more than 30 minutes late or misses the appointment is a no-show, forfeits the exam fee and loses an attempt, which is counted as a failed attempt.

CSMLS says results are released online within 45 days of the exam date, after its own checks and an analysis by a third-party psychometrician. The 2027 "results released by" dates are 12 April, 10 August and 13 December. You get an email with a link to the results portal; CSMLS does not give results by phone. A pass shows the Angoff score; an unsuccessful candidate sees their own score and the Angoff score, with their performance in the categories of the exam blueprint.
