The written exam is not the expensive part of getting your instrument rating. The flight training handles that. But it's still worth knowing what the written will actually cost you before you book.
The exam fee
Transport Canada written exams are administered by designated exam centres across Canada. The fee is set by each centre — Transport Canada doesn't charge candidates directly. Most centres charge between $50 and $100 CAD to administer the INRAT.
Some flight schools include the exam fee in their instrument rating ground school package. If yours does, confirm it in writing before booking separately.
What the fee covers
The exam centre fee covers the room, the computer terminal, the invigilator, and the official result. You get your result immediately when you finish. There's no separate Transport Canada fee on top of that.
The fee does not cover study materials or retakes. Each attempt is booked and paid separately. Before your appointment, review what to bring to the INRAT exam — the ID requirements are specific and not meeting them can prevent you from writing.

How to find and book an exam centre
Transport Canada maintains a list of designated exam centres by province on the TC website. Most major flight schools and aviation colleges are designated — if you're training at a school, ask your instructor before searching independently.
To book:
- Find a designated exam centre near you (Transport Canada's site lists them by province)
- Contact the centre directly — most take bookings by phone or email
- Confirm the fee, available dates, and ID requirements before your appointment
- Bring two pieces of government-issued ID, one with a photo — see what to bring to the INRAT exam for the full list
There's no Transport Canada online booking portal. You contact the centre directly. Availability varies — popular centres near flight schools can book up two to three weeks out during peak training season (spring and summer).
How many attempts should you budget for?
One. Candidates who prepare properly pass on the first attempt. If you want to be conservative, set aside enough for two.
The real cost of a failed attempt isn't the re-exam fee — it's the delay. Failing pushes back your instrument rating timeline, which matters if you're on a professional track or have flights planned around it. Good prep is cheap relative to that.
If you fail: retake rules and wait time
There is no mandatory waiting period to retake the INRAT after a failed attempt. You can book another appointment as soon as the exam centre has availability. However, booking again the next day without additional studying is a poor use of money — the question bank is large and the same weaknesses will surface.
Transport Canada does not limit the number of attempts. Your result from each attempt is recorded, but there's no rule preventing you from retaking immediately. That said, if you've failed twice, the problem is almost always preparation quality, not bad luck. Review your category scores, identify which areas dropped you, and go back to the TP 691E for those sections before booking again.
Your score report shows your result by category — not just pass or fail. That breakdown is the most useful piece of information you'll get from a failed attempt. Use it.
INRAT cost vs other Transport Canada written exams
The INRAT sits in the middle of the Transport Canada written exam cost range. For context:
| Exam | Typical fee |
|---|---|
| PPL written (PSTAR) | $20–$50 |
| CPL written | $50–$100 |
| INRAT written | $50–$100 |
| ATPL written | $50–$100 |
The written exam fee is a small fraction of the total cost of any rating. For the instrument rating, the flight training requirement — typically 40 hours of instrument time — is where the real cost sits. The written is a checkbox on the way there.
Is ground school worth it?
For most candidates preparing for the written exam specifically, no. The TP 691E covers everything and it's free. A practice question platform to test your knowledge and find gaps costs a fraction of ground school.
Ground school makes more sense when you want a scheduled classroom environment, need an instructor available for questions in real time, or are combining written prep with your actual instrument flight training. As a standalone strategy for passing the written exam, it costs more than necessary.
The candidates who spend the most on written exam prep aren't the ones who pass — they're often the ones who paid for ground school, got a false sense of coverage, skipped the TP 691E, and showed up unprepared for the specific way Transport Canada phrases questions. Knowing when you're actually ready to book matters more than how much you've spent.
