You have a confirmation number sitting in your inbox, you’ve typed it into the retrieval tool, and the system is telling you it can’t find anything. That confirmation number is real: the application exists. The problem is almost always a mismatch between what you submitted and what you’re entering now, or a timing issue that resolves on its own. Either way, there is a clear sequence for working through it. If the problem began at the payment step, read what to do when a card is declined. ...

You’re at the application form, passport open on the desk, and the field staring back at you says “email address.” You don’t have one — or you have one somewhere but can’t remember the password, or you’ve always used your daughter’s. The question is simple: can you get a Canada eTA without an email address of your own? The form itself is in English and French only; the language guide lists the help available in other languages. ...

Short version: no, Canadian airport security doesn’t check your eTA. Canadian airport security screening, run by the Canadian Air Transport Security Authority (CATSA), checks what you’re carrying, not your travel authorization. Your eTA is checked at two other points instead: by the airline when you check in for your flight to Canada, and by the border services officer when you land. If you’re standing in a CATSA line, your eTA has already been checked: by the border officer if you entered Canada and are now flying domestically or home, or by your airline at check-in if you’re connecting internationally without passing through the border. ...

Once your Canada eTA is submitted, pending or approved, its data can’t be edited; the only fix IRCC offers is a new application. But that doesn’t mean every mistake matters equally. A wrong passport number or a name that no longer matches your passport will stop you at check-in; a wrong home address or phone number isn’t checked against your passport at all. The first step is sorting out which kind of field you’re dealing with, because that decides whether you need to act today or not at all. If the mistake is in your name, see how to enter your name so that it matches the passport. ...

You’re standing at the primary inspection counter at Toronto Pearson, passport in hand, eTA approved weeks ago. The officer looks up and asks where you’re staying, how long you plan to be in Canada, and what you do for work back home. You weren’t expecting this. You thought the eTA had already cleared you. An approved eTA does not guarantee entry into Canada. It’s a pre-screening tool, not a boarding pass for the country. Every traveller — regardless of eTA status — must satisfy a Canada Border Services Agency (CBSA) officer at the point of arrival before being admitted. That single fact is what most people misunderstand, and it shapes everything about how you should prepare. ...

You’re partway through the eTA form when you notice the passport number you typed doesn’t match what’s printed in your passport. Or you’ve spelled your name differently than it appears on your travel document. The fix right now is simple: correct it before you submit. Once you’ve paid and the application is processed, the eTA is electronically linked to whatever passport number you entered — right or wrong — and an incorrect one may prevent you from boarding your flight to Canada entirely. Names are the most common thing to get wrong; this guide to name mismatches shows what to copy from the passport. ...

Your eTA approval email has arrived, your plans have since fallen apart, and now you’re staring at that confirmation wondering if you need to do something about it. You don’t. There is no requirement to notify Canadian authorities, cancel the eTA, or take any action at all when you decide not to use an approved eTA. It simply sits there, attached to your passport, valid and unused — and that is completely fine. ...

The short answer: a Canada eTA lasts up to five years, but never longer than the passport it’s linked to, so it ends on whichever date comes first. While it is valid you can travel to Canada as often as you like, each stay normally up to six months. To see whether yours still works, you can check your eTA status through a paid private service, separate from the Government of Canada. ...

The seatbelt sign clicks off, the plane taxis to the gate, and everyone around you starts reaching for overhead bins. You have an approved eTA, your passport is in your bag, and you’re wondering exactly what the next hour looks like. Here’s the direct answer: your eTA got you on the plane, but entry into Canada is decided by a border services officer when you arrive. The eTA is a pre-screening tool, not a permission slip. That said, if your documents are in order and you’re straightforward with the officer, the process at a major Canadian airport typically moves quickly. ...

In a Nutshell An eTA is tied to air travel only. If your plans involve driving across the border or arriving by ferry, your approved eTA has no role at the crossing — what matters is your proof of identity and citizenship. The document requirements differ by entry mode, and knowing which applies to you before you travel is the difference between a straightforward crossing and a real problem at the booth. If you’re still sorting out your air travel plans, an eTA application is the right starting point for that route. Flying in instead? The first-time application walkthrough covers the steps. ...
