You’re scrolling through your inbox, searching “Canada eTA” for the third time, and nothing useful is coming up. Maybe the confirmation email went to spam, maybe you applied months ago and the thread is buried, or maybe you genuinely can’t remember whether you finished the application at all. Before you start over, stop: an eTA is not a document you carry. It’s an electronic record tied to your passport number, and if it was approved, it still exists in the system whether you have the email or not.
Most travellers in this situation do not need to reapply. The question is simply whether your existing eTA is still valid — and that’s a check you can do in a few minutes.
Your eTA Probably Still Exists — Here’s How to Check
Start with your email, but search smarter. The confirmation comes from the Government of Canada’s immigration system, so search for “IRCC” or “Immigration, Refugees and Citizenship” rather than just “eTA.” Check your spam and any secondary email addresses you might have used. If you find an email with an application number, that’s all you need to confirm your status.
If the email is genuinely gone, the next step is the Government of Canada’s Application status tracker. To register, you’ll need your unique client identifier (UCI) or client ID, your application number, your first and last name, your date of birth, and your place of birth. If you’ve previously used the older Client Application Status (CAS) tool, you’ll need to create a new account regardless. Once you’re in, the tracker shows the current status of your eTA.
Alternatively, if you have an IRCC account from the application itself, signing back in may surface your eTA record directly.
One thing worth knowing about the tracker: status updates only appear after you’ve received an acknowledgement of receipt (AOR) letter or email. If your application was very recent and you haven’t had any confirmation at all, the tracker may only show your application receipt date and contact information — not a final decision. In that case, you’re likely still waiting on processing rather than dealing with a lost approval. The Canada eTA processing time guide covers what typical timelines look like and when waiting becomes a concern worth acting on.
Three Reasons Your eTA Might Be Invalid (and What That Means)
Finding your eTA in the system is one thing; confirming it’s actually usable is another. There are three situations where a valid-looking eTA won’t get you on a plane.
Your passport has changed. An eTA is linked to the specific passport you used when you applied. If you’ve renewed your passport since then, the eTA attached to the old passport does not transfer automatically. You’ll need to apply again using your new passport details. This is the single most common reason a traveller thinks their eTA is “lost” when it’s actually just attached to a document they no longer carry. If you’re in this situation, the full picture is laid out in what happens to your eTA after passport details change.
Your eTA has expired. An eTA is valid for a specific period. If significant time has passed since you applied, check the expiry date in the tracker. An expired eTA means reapplying — there’s no renewal process, just a new application.
Your eTA has been suspended. This is less common but worth knowing. Canada can temporarily suspend eTAs under certain public health measures. As of July 20, 2026, foreign nationals who have visited the Democratic Republic of the Congo within the past 21 days cannot travel to Canada. Additionally, foreign nationals who listed the Democratic Republic of the Congo, South Sudan, or Uganda as their last country of residence in their immigration application may have their eTAs temporarily suspended due to Ebola-related measures — and a suspended eTA cannot be used to board a plane or travel to Canada. If your eTA is suspended, you would have been notified by email. The suspension doesn’t extend your eTA’s expiry date, so if your authorization is close to expiring while suspended, you’d need to apply for a new one before travelling. When the measures end, suspended eTAs reactivate automatically without any action on your part. If you believe you have grounds for an exemption, you can request one by explaining your situation and providing evidence that you don’t pose a public health risk.
Here’s a quick way to read your situation against these three scenarios:
| eTA is still valid | eTA is invalid or unusable | |
|---|---|---|
| Passport status | Same passport used in the original application | Passport renewed since eTA was issued |
| eTA age | Not past expiry date | Expired, or expiry is imminent |
| Confirmation found | Email or tracker shows “approved” | No record found, or status shows “expired” or “suspended” |
| Next step | Travel as planned — no action needed | Reapply before booking or checking in |
How to Reapply If Checking Confirms You Need To
If the three-step check above lands you in the right column of that table, reapplying is straightforward. The process is the same as a first application: you’ll need your current passport, contact details, and answers to the standard background questions. Don’t leave this until the night before your flight — if your case goes to manual review, you’ll want time to follow up.
If you’re reapplying, submit a new eTA application through get-eta.com, which walks you through each field again so a small mistake doesn’t force a second do-over.
A few things that catch people out during reapplication:
Make sure every detail matches your current passport exactly. A mismatch between the name or passport number on your eTA and the document you present at check-in is grounds for being refused boarding. If you’ve made an error on a previous application, the process for correcting it is different from simply reapplying — how to correct mistakes on your Canada eTA application explains when a correction is the right route versus starting fresh.
If you’re a dual citizen, you need to apply with the passport of the eTA-eligible country — and then travel using that same passport. Mixing them up is a surprisingly easy mistake that invalidates the whole exercise.
Transit passengers are not exempt. If you’re connecting through a Canadian airport without leaving the international zone, you still need a valid eTA. The rules and the check process are the same.
What Happens at the Airport Once You Have a Valid eTA
This is where the “lost eTA” worry tends to resurface, and it’s worth putting it to rest. You don’t present your eTA at check-in the way you would a boarding pass or a visa sticker. The airline’s check-in system queries your passport number electronically and confirms your eTA status automatically. If it comes back valid, you board. If it doesn’t, you don’t — which is exactly why confirming your status before you get to the airport matters.
You don’t need to print anything, carry a confirmation number, or show an email. The eTA is in the system, and the system talks to the airline. At the Canadian border itself, the officer can see your eTA status the moment they scan your passport.
The practical implication: if the tracker shows your eTA as approved and your passport hasn’t changed, you’re ready to fly. The absence of a confirmation email is not a problem. What would be a problem is discovering at the check-in counter that your authorization expired six months ago, or that it’s tied to a passport you left at home.
Run the status check now, before you book anything else. If the tracker confirms an active eTA on your current passport, you’re done. If it surfaces a problem — expiry, a passport mismatch, or a suspension — you’ll have the lead time to sort it out without the trip being at risk.
