MMI Questions at Canadian Med Schools: Station Types and How to Train for Each

The MMI was invented at McMaster, and Canadian schools remain its most devoted users. Once you understand the format, it's actually a gift to prepared applicants. Every station is scored independently by a different rater, so one rough station can't sink your interview, and because the station types repeat across schools, the practice you put in transfers everywhere you interview.

1. Ethical dilemma stations

This is the classic MMI station: a scenario with genuine tension between two defensible positions, like a colleague's mistake, a resource allocation problem, or a clash between patient autonomy and safety. Raters score the quality of your reasoning rather than which side you land on. The way to train is to practice one consistent framework, moving through stakeholders, the principles in tension, your decision, and a safeguard, until it holds up under an eight-minute clock.

2. Role-play stations

You walk into the room and an actor is upset. Maybe you're breaking bad news, confronting a friend, or calming a stranger down. These stations are won or lost in the first sixty seconds, and the key is acknowledging the emotion in the room before you go anywhere near the problem. This is also the station type where solo prep fails hardest, for the obvious reason that you can't role-play against yourself. Live mocks with an acting partner are close to irreplaceable here.

3. Collaboration stations

You might build or draw something with a partner, sometimes with a communication constraint thrown in, or work through a task alongside another applicant. Raters are watching your process: whether you check for understanding, share the airtime, and adapt when your approach clearly isn't working. The trainable skill is narrating your thinking out loud, because silence in these stations reads as either domination or disengagement.

4. Health policy stations

These are Canadian-specific and chronically underestimated. Expect topics like pharmacare, rural physician shortages, wait times, Indigenous health, and supervised consumption sites. You aren't scored on your position, you're scored on whether you understand the issue from more than one side. A good approach is to build a one-page brief on each of the ten or so recurring Canadian health topics and practice speaking to both sides of each one for two minutes.

5. Personal stations

Questions like 'tell me about a failure' or 'why medicine, and why now' look easy, and that's the trap, because unstructured honesty rambles. Prepare six to eight core stories from your own file and practice mapping them onto whatever the prompt asks, always ending with a reflection that shows what changed in you afterwards.

How to structure your prep

• •Do two to four full timed circuits before interview day, spaced about a week apart.
• •Debrief every station against a rubric covering structure, empathy, communication, and judgment.
• •Between circuits, drill only your two weakest station types, since targeted reps beat general volume.
• •In the final week, run one consolidation circuit, then stop adding new material and protect your sleep.

Interview season in Canada is short and most schools give you exactly one shot per cycle. Walk in with the rhythm already in your body and the MMI stops feeling like a gauntlet and starts feeling like a stage.
