Best Study Resources for the Canadian IFR Written Exam

Most of what comes up when you search for IFR practice questions is American. FAA regs, Class B airspace, VOR airways that don't match Canadian charts. You can put in three weeks of solid study and still walk into the INRAT underprepared — not because you slacked off, but because you were studying the wrong country's rules the whole time.

Nobody enjoys reading the TP 691E. I've assigned it to hundreds of students and not one has come back excited about it. Read it anyway. The exam is built from this document — the question writers pull directly from it. Students who skip it and go straight to practice questions develop blind spots they don't catch until they're deep into a timed exam and something doesn't add up.

One read-through, start to finish. You're not trying to memorize it. You're building a working picture of how IFR works in Canada — CARs, RNAV approaches, altitude rules, the whole thing. Once you have that, the practice questions actually stick.

What to avoid

Sporty's, King Schools, Dauntless, the majority of apps on the App Store and Google Play — good products, wrong exam. Canadian IFR isn't just American IFR with a different flag. The airspace classifications are different. The separation minima are different. The approach procedures reference CARs 602, not FARs. Use FAA material on the INRAT and it won't just leave gaps — on certain questions it'll point you at the wrong answer with confidence.

Quick test: if a resource cites FARs anywhere, it's American. Put it down.

How to use these together

Read the TP 691E first. Then run a full practice session and find out where you actually stand by category. Don't try to study everything equally — you don't have time and you don't need to. Go back to the TP 691E for your weak categories and work through those sections until your accuracy is consistently above 75%. In the final week before your exam, run full timed simulations. The real INRAT is 50 questions with a 3-hour limit. Most people don't find that tight, but you want to have already done it at speed before you're sitting in the exam room at Transport Canada.

Most candidates who fail did one of two things: they skipped the TP 691E and drilled questions without the foundation to understand why the answers are what they are, or they drilled questions, saw their weak categories, and kept drilling the same strong categories anyway. The INRAT is designed to catch rote memorization. The explanations matter. For a practical rundown of which topic areas cause the most wrong answers and what the tricky question styles look like, read the INRAT practice area question guide. And when your scores are consistently where they need to be, the guide on when to book the INRAT walks through exactly what "ready" looks like before you commit to a date.
