CaRMS Timeline 2027 for IMGs: Every Deadline That Actually Matters
MDReview Editorial — written with input from Canadian residents and medical students.
The CaRMS Match runs on rails. Miss a document upload window by a day and your application to that program is done — no appeal, no exceptions. This is a special problem for international medical graduates, because IMG deadlines are earlier, the credentialing chain is longer, and one delayed source verification can cost you a match cycle.
Here is the practical CaRMS 2027 timeline built specifically for IMGs entering the R-1 Main Residency Match, plus the exam and credentialing prerequisites that need to be done long before CaRMS opens.
The 12-month view
Working backwards from Match Day (early March 2027), the critical windows are:
| Window | What happens |
|---|---|
| March 2026 – July 2026 | MCCQE1 written, NAC OSCE booked or written |
| July – August 2026 | Source verification submitted to physiciansapply |
| September 2026 | CaRMS registration opens; document upload begins |
| October – November 2026 | Programs post positions; personal letters + reference letters uploaded |
| Late November 2026 | File Review deadline (all documents must be visible to programs) |
| December 2026 – January 2027 | Interview offers released and scheduled |
| January – early February 2027 | Interviews conducted (virtual for most programs) |
| Late February 2027 | Rank order list deadline |
| Early March 2027 | Match Day (R-1) |
Every date is nudged annually — check the official CaRMS and MCC calendars before committing.
The IMG prerequisite chain
CaRMS itself is the easy part. The prerequisite chain is what catches IMGs off-guard.
1. Source verification (physiciansapply.ca)
Your medical school must send an official verification of your MD credential directly to the Medical Council of Canada. This can take 4–16 weeks depending on the school and country. Start this the moment you decide to apply — not after MCCQE1.
2. MCCQE Part I
Written year-round in Prometric testing centres. Results in ~8 weeks. To have your MCCQE1 result visible in the CaRMS file by the November file-review deadline, you should write no later than early September 2026. See how to apply for the MCCQE1 for the physiciansapply flow.
3. NAC OSCE
Twice-yearly sittings (spring and fall). Fall 2026 results are typically released in time for CaRMS 2027; spring 2026 gives you a safety net for a retake. Most IMG-friendly programs require or strongly prefer a NAC OSCE result. See the NAC OSCE prep plan for the 6-week structure that pairs with MCCQE1.
4. Language proficiency
If your medical education was not in English or French, provide IELTS Academic (typically ≥ 7.0 each band) or equivalent. Book the test 3+ months out.
5. Provincial IMG assessment programs
Several provinces (BC, Alberta, Manitoba, Saskatchewan, Ontario, Quebec) run their own IMG assessment or practice-ready pathways with separate deadlines that often precede CaRMS. If you're targeting practice-ready or provincial streams, treat those as parallel processes with earlier cutoffs.
The 2027 cycle month-by-month
March – June 2026: build the foundation
- Register with physiciansapply.ca and start source verification immediately.
- Book MCCQE1 for a July–August sitting. Book NAC OSCE for fall 2026 (write spring if you want a retake buffer).
- Draft your personal letter. First drafts are always bad — you want six weeks of revision, not six days.
- Line up three reference letters — one core, at least one Canadian if possible (electives, observerships, research).
July – September 2026: write the exams
- Write MCCQE1. Results come in October — that's fine, the score doesn't need to be on file until November.
- Write NAC OSCE if scheduled for fall.
- Finalize your CV in the CaRMS format (chronological, no gaps unexplained).
- Confirm all reference letter writers have the CaRMS instructions and the November deadline.
October 2026: CaRMS opens
- Registration and document upload go live in early October (exact date on carms.ca).
- Programs publish descriptions, eligibility criteria, and required documents.
- Upload your personal letter, CV, transcripts, MSPR/MSPE, MCC transcript, NAC OSCE result, and any electives documentation.
- Programs vary in what they require — read each program's page. Missing one document = auto-reject at file review.
November 2026: file review deadline
- All documents must be visible to programs by the file review deadline (typically mid-to-late November).
- Reference letters are uploaded by referees, not you. Chase them politely starting late October.
- After this deadline, you can still update some fields, but core documents are locked in.
December 2026 – January 2027: interviews
- Interview offers come out in waves through December.
- Most programs interview virtually. Prepare with structured mock interviews (MMI + traditional).
- Keep interview slots flexible — offers for later interviews often depend on cancellations.
February 2027: rank order list
- ROL deadline is late February — usually a Thursday at 12:00 PM ET.
- Rank truthfully by preference, not by where you think you'll match. The algorithm favours applicants.
- Do not withdraw programs after ranking unless you would refuse a match there.
March 2027: Match Day
- Match Day for R-1 is early March. First-iteration results release simultaneously.
- Unmatched applicants proceed to the second iteration in April.
The three IMG-specific traps
- Source verification takes longer than you think. Start this the day you commit to applying. Follow up with your medical school monthly.
- NAC OSCE is not optional for most IMG-designated positions. Even when the program says "recommended", the practical reality is that competitive files have it.
- Not every program accepts IMGs. IMG-designated seats are a smaller pool than CMG seats and vary drastically by province and specialty. Check the program eligibility page on carms.ca before writing personal letters — do not waste words applying to programs you are not eligible for.
How exam prep fits
The exam and Match calendars overlap uncomfortably. The rough sequencing that works:
- 12 months before Match Day: MCCQE1 study begins in earnest (12-week IMG plan).
- 9 months before: MCCQE1 written; NAC OSCE prep starts.
- 6 months before: NAC OSCE written; personal letter draft complete.
- 5 months before: CaRMS opens; upload begins.
- 3 months before: interviews.

Where MDReview fits
MDReview's MCCQE1 question bank is aligned to the MCC blueprint and includes AI-graded CDM cases — the two components CaRMS-bound IMGs need most. Pair it with NAC OSCE-style practice cases (spring 2026) and you have both prerequisite exams covered from one subscription.
