The short answer: yes, an approved eTA stays valid when your flight is cancelled, moved to another date or rebooked with a different airline, because it is linked to your passport, not to a ticket, date or airport. Before the new trip, check only three things: you are flying on the same passport, the eTA and passport are still valid on the new travel date, and you are still arriving by air. If you don’t have an eTA yet, you can apply for a Canada eTA through a paid private service, separate from the Government of Canada.
Applying on canada.ca costs only the government fee. A new connection or a new carrier does not change the eTA itself; what matters is the passport, whether the new dates fall inside the validity, and the way you cross the border.
Once a new ticket is in your inbox, the first job is to confirm your eTA status before the new flight, because everything below assumes the approval is real and sits on the passport you will carry. This article covers what to re-check when the trip itself has changed.
Why doesn’t a cancelled flight affect your eTA?
The eTA is electronically linked to the passport you used to apply. It holds no flight number, no airline and no airport. The application form asks one question about timing: whether you know when you will travel to Canada. “No” is an acceptable answer, and anything you do enter is there to help with processing, not to fix a date. A cancellation or a rebooking therefore leaves an approved eTA untouched, because there is no booking inside it to cancel.
At check-in the airline scans the passport you applied with and sees the approval, so you print nothing. The eTA is also not a single-use document: one trip does not use it up, and repeat visits need no new application while it stays valid. Canada’s own page on what an eTA is linked to makes the same point, with the passport as the anchor. An eTA does not guarantee entry, though; the border officer still decides on arrival.
What changed in your trip, and does it matter?
Most changes after a cancellation fall into a handful of cases. The table shows whether the approval still works and what to look at.
| What changed | Does your eTA still work? | What to check |
|---|---|---|
| Flight cancelled, same route, new date | Yes | The new date falls before the eTA and the passport expire |
| Moved to an earlier or a later date | Yes | Same check; an earlier flight with no decision yet is covered in the next section |
| Different airline | Yes | The new check-in desk scans the same passport |
| Different Canadian arrival airport, such as Toronto instead of Vancouver | Yes | You still fly to or transit through a Canadian airport |
| New connection in a Canadian airport | Yes, and the eTA covers the connection | You carry the passport you applied with |
| New connection in the United States, then a flight to Canada | Yes, for the Canadian leg | U.S. requirements are for the U.S. authorities to answer |
| Fly to the United States, then drive, take a bus or a train into Canada | Not needed for a land crossing; visa-required nationals need a visa | See the section on switching to the road |
| New passport, or passport expires before the new date | No | See the section on passport changes |
A change of airline, airport or date is invisible to the eTA, while a change of passport, or a trip pushed past the expiry date, is not. If your situation matches two rows, both checks apply.
Rebooked onto an earlier flight, but no decision yet?
This is the one case where a rebooking can hurt. An earlier departure shrinks the time an undecided application has, and you should not set off for Canada while the decision is still pending. Many applicants get an answer in minutes; for others it is several days. When IRCC needs something more, it writes within 72 hours of the application, and that message can land in spam.
If the new flight is only days away and nothing has been decided, IRCC’s own advice is that you may want to reschedule. Silence is a different problem: 72 hours after applying with no email carrying an application number calls for IRCC’s web form, not a second application. In that form the type of application is “Electronic Travel Authorization” and the enquiry is “Case Specific Enquiries”. A day-by-day routine is in what to check in the week before you fly, and it suits a trip squeezed by a rebooking too.
New route through another airport: Canada or the U.S.?
If the new itinerary connects through a Canadian airport, you need an eTA for that connection, and the approved one covers it. If you carry on to a second Canadian city afterwards, that onward leg is travel within Canada, which needs no eTA.
If the new route goes through the United States, your eTA is the same for the flight that finally lands in Canada. What the U.S. asks of you for a connection is decided by the U.S. authorities and is outside this article, so confirm it with them before you accept a rebooking through an American airport.
Switching from a flight to driving, a bus or a train?
Sometimes the cancellation leads to a different plan: fly to a U.S. city, then cross by car, bus or train. Visa-exempt travellers do not need an eTA when they arrive in Canada by car, bus, train or boat, a cruise ship included, so the approval is simply not used on that crossing. Which documents to carry at a land crossing has its own article, and the question of whether a road trip into Canada needs an eTA has a short answer of its own.
There is one nuance. Citizens of visa-required countries who are allowed to use an eTA can use it only to fly. If they arrive by land or sea, they need a visa. Their eTA is not lost and stays good for a later flight while it is valid, but it does not replace a visa at the road border.
Did your passport change or expire while the trip was on hold?
The approval lasts up to five years, or less if the passport ends sooner. A long delay before the rebooked trip can turn a good approval into a lapsed one: if the rebooked trip falls after the passport’s end date, the eTA is no longer valid on that day. Read what happens to the eTA when the passport runs out if your expiry date is close to the new dates.
A new passport means a new eTA, and the old approval does not move over to it. An approved eTA cannot be edited either: if something has to change, you complete a new application. Look at the passport number printed in the approval email; if it is not the number of the passport you will carry, a new application is needed. Last-minute applications may not leave enough time, so do it as soon as the new ticket is booked.
Flight cancelled vs eTA cancelled: what’s the difference?
The two get mixed up in search results, but they are unrelated. When an airline cancels a flight, your eTA is untouched. When an eTA is cancelled, it is an immigration officer’s decision, for example because information shows the person has become inadmissible to Canada, and the traveller is told by email.
With a cancelled eTA you cannot fly, because you would be stopped from boarding the flight to Canada. The sensible course is to fix the underlying reason before applying again. If no such email has reached you and you still hold the same passport, nothing suggests your eTA has changed, and a cancelled flight does not cause one.
How do you check your eTA before the rebooked flight?
A quick look takes a few minutes. You can check your eTA status with the details of the passport you applied with (its number, issuing country, and issue and expiry dates) plus your application number, or for an approved eTA the eTA number or UCI; the page also asks for an email address.
Your approval email includes the eTA number, so keep it where you can find it. Make sure the expiry date is later than the end of the new trip, and if the result shows anything other than approved, read it carefully before you spend more on the journey.
The short version
- A cancelled, moved or rebooked flight does not touch an approved eTA, because it is linked to the passport.
- A different date, airline or Canadian airport does not affect the eTA.
- Check the passport, the expiry dates of the eTA and the passport, and that you still arrive by air.
- An earlier flight with no decision yet is the risky case: do not travel until a decision is made.
- A new passport needs a new eTA, and an approved eTA cannot be edited.
- A cancelled flight and a cancelled eTA are different things; the second comes with an email about the cancellation.
FAQ
How do I find out if my eTA is still valid? Look up the status with your passport details and your eTA number or UCI. Then compare the new travel date with the expiry date of the passport, since the eTA ends no later than the passport does.
Can eTA be cancelled? Yes. An immigration officer can cancel an eTA, for example when information shows the traveller has become inadmissible, and the traveller is told by email. A cancelled flight has no effect on the eTA. With a cancelled eTA you would not be allowed to board.
Do I need an eTA if I am transiting through Canada? Yes, if you are a visa-exempt traveller changing planes at a Canadian airport. An approved eTA covers the connection, so a rebooking onto a new route through Canada does not call for a new one.
Is my Canadian eTA linked to my passport? Yes. It is electronically linked to the passport you used to apply, and that is the passport you show at check-in.
Do I need a new eTA if I changed my passport? Yes. A new passport needs a new eTA, because the old approval does not transfer to it.
