Transport Canada pilot logbook requirements (CAR 401.08)

I started my pilot logbook in 1997, on paper, because paper was all there was. A small ten-row book first, then the larger twenty-row format. Both had a page at the front for licences and type ratings. I never used it.

Nearly thirty years on, I’ve had that logbook read by Transport Canada and by airline interviewers. I’ve found my own arithmetic errors in it, and I’ve rebuilt it twice. This is what the regulation actually asks for, and what I wish I’d been told on day one.

Who has to keep a pilot logbook in Canada?

Anyone applying for or holding a Canadian flight crew permit, licence or rating has to keep a personal log (CAR 401.08). It has two jobs. One is documenting the experience that got you a permit, licence or rating. The other is documenting recency.

So it’s not a formality you can drop once the licence arrives. It’s how you prove recency for as long as you fly. Transport Canada’s own instructions on recurrent training put it plainly: “What constitutes proof of a pilot being current is a logbook entry, not a certificate” (TC recurrent-training instructions). It’s also the evidence file for every licence and job you’ll apply for after that.

What must each logbook entry contain?

CAR 401.08(2) sets out the minimum. Your log has to show your name, and for each flight:

• the date
• the aircraft type and its registration
• the crew position you flew in
• the conditions: day or night, VFR or IFR
• for aeroplanes and helicopters, where you departed and where you landed
• for aeroplanes, every intermediate take-off and landing
• the flight time
• for gliders, the launch method; for balloons, the inflation method

That’s all the regulation requires, and it’s less than most printed logbooks give you room for. The extra columns in a commercial logbook are there because licence requirements and employers ask about categories the regulation doesn’t list. Cross-country, instrument and dual time, for example. Logging flight time in Canada covers what counts in each of those columns, and in PIC and co-pilot time. If you also hold an FAA certificate, the US list is in FAA pilot logbook requirements.

Who can write in it

Only you, or someone you’ve authorised (CAR 401.08). That second part is how an instructor’s endorsement or an employer’s validation stamp ends up in your book. Those entries matter more later than they seem to at the time.

Does it have to be on paper?

CAR 401.08 lists what a personal log must contain. It doesn’t say what the log must be made of. It doesn’t mention paper, a particular printed layout, or a particular column order.

Transport Canada’s own licence-application instructions say it directly: “You can email your e-logbook or a scanned copy of your paper logbook” (TC licence application page). Whatever format you keep, the content requirements above still apply, and so does the rule about who can make entries. Are electronic pilot logbooks legal in Canada? covers what Transport Canada accepts, who can sign a digital log, and what to keep on paper.

When someone actually reads it

For most of your career, nobody looks at your logbook. Then, at a few moments, someone reads it closely.

Licence applications. When you apply for a higher licence, your log goes in with the application. Transport Canada’s application guidance sets the bar: “Your personal flight log or Pilot Training Record should provide clear evidence of flight hours flown” (AC 401-002). The log is audited against the requirements for the licence you’re applying for, so every total you claim has to be traceable to entries that add up.

Airline interviews. Expect to bring your logbook. Some interviewers only check the totals against what you declared. Others go further and look for the validation entries previous employers made against the time you flew for them. If you claim hours on a type, they may want to see who signed for them.

What happens if you lose your pilot logbook?

Standard 421 covers this case, and it’s harsher than most pilots expect (Standard 421.08). If your log is lost to fire, theft or similar, you can submit a sworn affidavit or statutory declaration. It has to include:

• your flying broken down by category
• your aircraft types and registrations
• your employers and dates
• an explanation of why the log can’t be produced

You’re expected to back it up with corroborating evidence, such as copies of aircraft journey log entries. An affidavit without corroborating evidence won’t be accepted for anything beyond the experience a Commercial Pilot Licence requires (Standard 421.08).

In other words, lose your log and you can get a Commercial Pilot Licence on your word. For an airline transport licence, you need proof. A digital log can be lost too, so keep a copy somewhere other than the device you log on.

Your employer’s records are not your logbook

Operators keep flight records, but for their own compliance, not yours. Their records and yours meet different requirements, so neither can stand in for the other.

I know pilots who didn’t keep a personal log through a job and later asked the company for their history. The company only kept a few years of records. The rest was gone, and no amount of asking could recover it. Keep your own log, every flight, even when the company is also recording it.

What trips pilots up

Arithmetic and handwriting. My paper log had addition errors, entries that were hard to read, and more crossed-out corrections than I’d like to admit. All of that made it harder for the Transport Canada auditor to follow, and an auditor who can’t follow your totals will ask about them.

The columns you didn’t know you’d need. A paper logbook has a fixed number of spare columns. Years in, you may need float time, turbine time, jet time, or time on a specific type for an application to a new aircraft or a career airline. Then you’re back-filling from memory, or inventing codes in the margins. The regulation’s list is short, but what employers ask about isn’t.

Start digital, and start early

This is the advice I didn’t find anywhere when I started.

I’ve switched formats twice. First I copied my whole paper log into a desktop app, one row at a time. That’s when I saw what a digital log is good for. Totals by category, by type or by period become a search instead of an evening with a calculator. When the app moved to a subscription, I left it. For a while my records were a pile of company Excel exports, until I built my own spreadsheet to hold everything. It worked, but every summary was a formula I had to write and maintain, and there was no clean way to print or send the log to anyone.

The lesson isn’t about which tool to use. It’s about when to start. Switching to a digital log gets harder the longer you wait. It’s a lot of work to sit down with a decade and eight thousand hours of handwritten rows and type them in again. Most experienced pilots I know who’d like a digital log don’t have one, and that’s why.

A student pilot has none of that backlog. If you’re just starting out, or you’re early enough that the next licence application and the first airline interview are still ahead of you, this is the cheapest your switch will ever be. Start the digital log now, and keep the paper one as well if an instructor or school asks for it. When someone asks for your log, you’ll send a file instead of spending a weekend with a calculator.

If you already have years on paper, you don’t have to retype them to start. Carry your paper totals forward as a single opening balance and log every new flight digitally from today. Your paper book stays the record for everything before that date, so keep it. If you do want the old rows digital as well, scanning tools can turn logbook pages into draft entries, which is faster than typing them. But they only produce drafts. You check each row against your paper original before it goes into your log, and that part stays your job.
