The Medicine Subspecialty Match (MSM) is for residents currently enrolled in an internal medicine residency training program who are looking to apply for subspecialty training.


Your first step before participating in the match should be to make sure to review the eligibility criteria to ensure you are eligible in the provinces in which you want to train.

Your CaRMS contract

You must agree to the applicant contract to participate in a CaRMS match. Read this document carefully, as it outlines your obligations, as well as those of CaRMS, throughout the match process.

Two iterations

The MSM is run in two phases, called iterations. If you do not match in the first iteration of the match, you can apply to unfilled positions in the second iteration.

Withdrawing from the match

You can withdraw from the match through CaRMS Online until the rank order list deadline found in the applicant timeline. Withdrawing from the match removes your application from all programs. In other words, you are no longer participating in the match. After you have withdrawn, you can reinstate your application as long as you do so before the rank order list deadline by contacting CaRMS at

You can withdraw individual program applications up until file review opens. You will receive a program credit to apply to another program within the same iteration. Program credits do not carry over to future iterations.
