“I’m an IMG. Should I write the MCCQE or Step 2 CK? Or both?” It is a common question, and the first thing to know is that these two exams are not rivals. They look alike on exam day — a long, multiple-choice sitting at a Prometric centre — but they open different doors, and neither one opens the other’s.
Short answer: They lead to different countries. For a Canadian residency, CaRMS requires IMGs to pass the MCCQE and the NAC (CaRMS: R-1 eligibility criteria); Step 2 CK, with Step 1 and an ECFMG Pathway, is the route to US residency. USMLE Steps replace the MCCQE only in Saskatchewan, Nova Scotia, New Brunswick and PEI, and on CaRMS’s current summary no province accepts them in place of the NAC. No official body rates one exam harder. First-time pass rates were 48% for IMGs on the MCCQE (2025–26) and 90% for takers from non-US schools on Step 2 CK (2024–25), though the groups and years differ.
A quick note on names: on 1 April 2026 the MCC renamed the MCCQE Part I to simply the MCCQE, with “no changes to the examination itself” (MCC: Qualifying Examination name update). Older pages, including CaRMS’s eligibility page, still say Part I.
What each exam opens
The MCCQE is a Canadian gate. The MCC states that passing it “is a requirement for international medical graduates applying for entry into a Canadian residency program”, and that a pass is one of the criteria for the Licentiate of the Medical Council of Canada (MCC: MCCQE). CaRMS says the same from the other side: IMGs must have written and passed both the NAC Examination and the MCCQE (CaRMS still calls it Part I), and some provinces may allow exceptions (CaRMS: R-1 eligibility criteria). Its provincial summary for the 2027 cycle lists them: Saskatchewan accepts USMLE Steps 1–3, and Nova Scotia, New Brunswick and Prince Edward Island accept Steps 1 and 2, in place of the MCCQE (CaRMS: Summary of MCC examination requirements).
Step 2 CK is a US gate. With Step 1 and an ECFMG Pathway, it counts towards ECFMG certification (ECFMG 2026 Information Booklet: requirements for certification), which the ACGME requires of IMGs entering accredited US residency or fellowship, and which Step 3 and an unrestricted US licence also need (ECFMG: Certification).
So Step 2 CK on its own, however strong, does not make an IMG CaRMS-eligible in any province, and an MCCQE pass does nothing for ECFMG certification.

Where the exam days feel different
Scheduling. The MCCQE runs in fixed windows; for 2027 they are 19 January–11 February, 21 April–8 June, 10 August–7 September and 5–26 October. Seats go first come, first served from five months out, and remote proctoring is gone (MCC: MCCQE scheduling). Step 2 CK is booked within an eligibility period you choose, so the MCC calendar is the tighter constraint.
Scoring logic. The MCCQE is criterion-referenced: you pass at 439 “regardless of how others perform”, with subscores across eight domains (MCC: MCCQE results). Step 2 CK reports a three-digit score with a pass at 218 (USMLE: Examination results and scoring).
How much of the prep carries over
Most of the medicine carries over: both exams test clinical reasoning on vignettes rather than recall, across internal medicine, paediatrics, obstetrics and gynaecology, psychiatry, surgery and emergency presentations.
What does not carry over is the context. The MCCQE is written to the level of a student graduating from a Canadian school, and its domains include health promotion and illness prevention, communication, psychosocial aspects and professional behaviours. In practice: Canadian screening programs and guideline thresholds, public-health reporting duties, and consent and capacity rules under Canadian law. A Step 2 CK question bank teaches the physiology and the differential, not what a Canadian examiner expects when the two countries’ guidelines diverge. More in how Canadian healthcare context shows up in MCCQE questions.
If you are writing both, use Step 2 CK-style volume for the clinical core, then give the final stretch before the MCCQE to Canadian material: ethics, law and population health, which US resources teach to US law and US guidelines.
A decision rule
Answer one question first: where do you intend to do residency?
- Canada only. Write the MCCQE and the NAC. Skip Step 2 CK unless you are targeting Nova Scotia, New Brunswick or PEI (USMLE Steps 1 and 2) or Saskatchewan (Steps 1, 2 and 3) in place of the MCCQE; you still need the NAC.
- United States only. Write Step 1 and Step 2 CK and complete an ECFMG Pathway. The MCCQE does not count towards ECFMG certification.
- Both countries, genuinely. Write Step 2 CK first while your clinical core is freshest, then the MCCQE within a few months. If you will apply to CaRMS and the NRMP in the same year, map both match timelines early so exams, applications and interviews don’t collide. Budget for both fee sets and a Canadian-context review block.
- Undecided. Commit to the country where you have a realistic route to residency, counting CaRMS’s provincial exceptions and any US visa issues. Two full-day exams “just in case” cost months.
One more timing point: the MCC lets students apply up to 15 months before their expected graduation, and IMGs can apply once they have submitted and paid for a source verification request for their degree (MCC: MCCQE eligibility and application). Verification depends on your school’s response time, so start it before you start studying. The same logic runs through which of the MCCQE and NAC to write first.
Frequently asked questions
Is the MCCQE harder than USMLE Step 2 CK?
No official body ranks them, but the published first-time pass rates are far apart. In the MCC’s 2025–26 year, 48% of 4,629 first-time IMG takers passed the MCCQE, against 91% of first-time Canadian graduates (MCC Annual Report 2025–26, p.31). On Step 2 CK in 2024–25, 90% of 16,186 first-time takers from non-US schools passed, a group that now includes Canadian schools (USMLE: Performance data). These are different groups and years, so not a difficulty ranking. Either way, about half of first-time IMGs fail the MCCQE, so prepare for it on its own terms. See the trend in our MCCQE pass rates for IMGs and CMGs.
Does Canada accept the USMLE instead of the MCCQE?
Only in a few provinces. CaRMS’s provincial summary lists USMLE Steps 1, 2 and 3 in place of the MCCQE for Saskatchewan, and Steps 1 and 2 for Nova Scotia, New Brunswick and Prince Edward Island (CaRMS: Summary of MCC examination requirements).
Do I still need the NAC if I have passed Step 2 CK?
Yes. No province on CaRMS’s summary accepts a USMLE Step in place of the NAC Examination. The listed alternatives are a pass on the former MCCQE Part II (Newfoundland and Labrador, Ontario) or the LMCC (Newfoundland and Labrador). Quebec’s medical schools still require the NAC, with narrow exceptions such as IMGs already training in Canada or the US (CaRMS: Summary of MCC examination requirements).
What is the Canadian equivalent of the USMLE?
There isn’t a single one. The MCCQE is the closest match to Step 2 CK: a one-day multiple-choice exam that IMGs need for a Canadian residency and that counts towards the LMCC (MCC: MCCQE). Clinical skills are tested separately in the NAC Examination, an OSCE. The USMLE no longer has a clinical-skills exam; its bulletin refers to the “formerly administered Step 2 Clinical Skills” (USMLE Bulletin: Eligibility).
