What Is an eTA for Canada? A Simple Explanation

Wondering what is a Canada eTA? If you’re planning a trip to Canada and you’re a citizen of a visa-exempt country, you generally don’t need a traditional visa, but rather an Electronic Travel Authorization (eTA).

What is a Canada eTA: definition

The eTA is an electronic requirement that has been mandatory since August 2015 for visa-exempt travelers flying to or transiting through Canada. It is linked to your passport and automatically verified during entry checks — you don’t receive any physical document.

Who needs a Canada eTA?

Citizens of many countries, including France, Belgium, Switzerland, and most EU member states, must hold a valid eTA to enter Canada by air. U.S. citizens are exempt. Travelers entering by land or sea (for example, driving from the United States) do not need an eTA.

Why use an assistance service?

The eTA is issued by the Canadian government, whose online form is available only in English and French. That is exactly where our service comes in: we assist you with your application, verify the completeness and consistency of your information before it is submitted, and remain available for any questions. The terms of our service are set out in our Terms & Conditions.

How long is a Canada eTA valid?

The eTA is valid for up to 5 years or until your passport expires, whichever comes first. It is automatically re-verified each time you enter Canada by air.

How long does processing take?

Most applications are approved within minutes. In some cases, additional documents are required, which can extend the process up to 72 hours. We recommend applying for your eTA well before your trip.

What a Canada eTA is, technically

An eTA is not a document. Nothing is posted to you, nothing is stamped in your passport and there is nothing to print. It is an electronic authorization recorded against your passport number, which the airline queries when you check in and the border services query when you arrive.

That single fact explains most of the rules around it: why the passport number has to be exact, why renewing the passport ends the authorization, and why a connection through a Canadian airport requires one even though you never meet an officer.

What it authorizes, and what it does not

It authorizes you to board a flight to Canada. It does not authorize entry — the officer on arrival decides that, and sets how long you may stay.
It covers tourism, visiting family, business meetings and transit. It does not cover working or studying, which need their own permits.
It allows an unlimited number of trips during its validity, on the passport it was issued against.

Who needs one

Visa-exempt travellers arriving by air. US citizens are exempt entirely. Travellers whose nationality is not visa-exempt need a visitor visa instead, whichever way they arrive — a different procedure, described in eTA or visitor visa. Arriving by road or by sea does not trigger the requirement, but one onward flight touching Canada does.

How long it lasts

Up to five years, or until the passport it is attached to expires, whichever comes first. Renewing that passport ends the authorization even if years remain on paper — the detail is set out in how long an eTA stays valid.

Why Canada introduced the eTA

Before the eTA existed, travellers from visa-exempt countries boarded flights to Canada with nothing more than a passport. Nobody had screened them until they stood in front of an officer at the arrival hall, which meant that a person who would be refused entry was only identified after a long-haul flight, with all the disruption that meant for the airline and the traveller.

The electronic authorization moved that check upstream. Since it became mandatory in 2016, a visa-exempt traveller is screened before departure, from home, in a few minutes. The airline then confirms the authorization at check-in, and anyone without one is stopped at the gate rather than on arrival. For the vast majority of travellers the change is invisible; for the small number who have a problem, it surfaces before they have even boarded.

Who does not need a Canada eTA

The list of exemptions is short, and it is worth reading carefully because several categories are routinely misunderstood:

Canadian citizens, including dual citizens. A dual Canadian citizen cannot fly to Canada on their other passport with an eTA; they must travel on a valid Canadian passport.
Permanent residents of Canada, who travel with their permanent resident card or a permanent resident travel document.
US citizens, who need a valid identity document such as a US passport.
US lawful permanent residents, who must present a valid passport together with their green card.
Travellers who already hold a valid Canadian visitor visa, since the visa replaces the authorization.
Anyone arriving by road or by sea, provided no part of the journey involves a flight into Canada.

Everyone else holding a passport from a visa-exempt country needs an eTA to fly to, or through, a Canadian airport.

The eTA for some visa-required nationalities

A limited number of travellers whose nationality normally requires a visitor visa can apply for an eTA instead, under specific conditions. Typically, the traveller must be flying to Canada and either hold a valid non-immigrant visa for the United States or have held a Canadian visa at some point in recent years. The conditions are narrow and attached to the person’s travel history, not only to their passport, so anyone in this situation should check their own eligibility carefully before assuming that the simpler route applies.

What the application actually asks

The form is short, but it covers more ground than many travellers expect:

Your travel document — document type, passport number, country of issue, issue and expiry dates.
Your identity — names exactly as printed, date and place of birth, gender, marital status, nationality.
Your contact details — the email address where the decision will be sent, and a home address.
Your occupation — current job, employer and the year you started, or the equivalent for students, retirees and people not working.
Background questions — previous refusals, criminal history and certain medical questions.
Your travel plans — whether you know when you will travel and, if so, your date.

Each of these is explained field by field in our step-by-step guide, and the documents to have ready are listed in what you need before applying.

After approval: what you carry

Nothing beyond your passport. The authorization is recorded electronically and found by the airline from your passport number. It is still worth keeping the confirmation email on your phone, because it contains your application number — useful if a check-in agent needs to look into a mismatch, and essential if you ever need to ask about your file.

On arrival, the border officer may ask about the purpose of your visit, how long you plan to stay, where you will be staying and how you will support yourself. These are ordinary questions, and the answers you give should match what you declared on your application.

Common questions

Is an eTA the same thing as a visa?

No. A visa is a document placed in your passport after a fuller assessment. An eTA is an electronic record that pre-clears visa-exempt travellers for air travel. You need one or the other, never both.

Can I work or study in Canada with an eTA?

No. The eTA covers tourism, visits, business meetings and transit. Working or studying requires a permit; when a visa-exempt traveller is granted one, an authorization is generally issued alongside it. Our guide to working and immigrating in Canada explains the main permit routes.

Can somebody else apply for me?

Yes. A parent can apply for a child, and a representative can submit on your behalf, provided the form declares it. The information itself must still be yours and must be accurate.

Do I need a new eTA for every trip?

No. One authorization covers unlimited trips while it is valid, on the passport it was issued against. See how long an eTA stays valid.
