The honest problem with studying for the INRAT is that most of the material online is American. FAA regs, FAA airspace, FAA procedures. Spend enough time with the wrong material and you'll walk into the exam confident about things that don't apply in Canada.

Here's what's worth using — and what to skip.

Note: I built IFRTEST.ca, so I'm biased about one of these. I've tried to be straight about where the free options are genuinely good and where the gaps are.

Start here: the official study guide (free)

Transport Canada TP 691E
Free
The official Transport Canada study and reference guide for the INRAT. Available as a free PDF on the TC website. Every topic on the exam is in here — this is the source document. Read it before you do anything else.
Best for: understanding the material. Not enough on its own — no practice questions, no self-testing.

The TP 691E is dry. Nobody enjoys reading it. Read it anyway. The exam is built from this document, and candidates who skip it and jump straight to practice questions often have holes in their understanding they don't realize until exam day.

Read it for comprehension, not memorization. You're building a mental model. The practice questions come after.

For practice questions

IFRTEST.ca
Recommended
476 practice questions built specifically for the Transport Canada INRAT — not adapted from FAA material. Covers all 13 categories. Includes a timed 50-question exam simulator that runs the full three hours, flashcards, a readiness dashboard that tracks accuracy per category, and an AI Instructor that explains why each answer is correct or wrong.
Best for: drilling all 13 categories, identifying weak spots, simulating the real exam. Free 10-question demo, no account needed.
INRAT Exam Prep (courses.inratexamprep.com)
Paid
A course-based platform with over 400 practice questions and a discussion forum. Been around for a while and has a decent reputation in the Canadian pilot community. More course-oriented than drill-oriented.
Best for: candidates who want a structured course format with community discussion.
Brampton Flight Centre Question Bank
Free
A collection of exam-style questions compiled by Brampton Flight Centre and available on their website. Not interactive — it's a document — but it's Canadian content and gives you a sense of question style.
Best for: a quick free supplement. Not enough on its own for serious prep.

What to avoid

Anything built for the FAA instrument written exam. This includes Sporty's, King Schools, Dauntless, and most apps in the iOS/Android app stores. They're great products — for the FAA exam. The regulations, airspace classifications, procedures, and chart formats are different enough that studying FAA material will actively mislead you on certain INRAT questions.

If you're not sure whether a resource is Canada-specific, check whether it references CARs (Canadian Aviation Regulations) or FARs (Federal Aviation Regulations). FARs = American. Walk away.

How to use these together

The order matters. Don't start with practice questions and use the study guide as a fallback when you get things wrong. That's backwards.

  1. Read the TP 691E — all of it, once through
  2. Do a full session of practice questions to see where you actually stand
  3. Go back to the TP 691E for the categories where you're weak
  4. Drill those categories specifically until you're consistently above 75%
  5. Run full timed exam simulations in the final week before your test date

The candidates who struggle are almost always the ones who skip step one, or who do step two and never go back to step three. Practice questions without understanding why answers are right or wrong is just memorization — and the INRAT questions are written to defeat memorization.
