The eTA (electronic Travel Authorization) is a digital permit issued by Immigration, Refugees and Citizenship Canada (IRCC) that lets you BOARD a flight to Canada without a visa. It is not a visa, it is not a piece of paper and it is not a guarantee of anything: «An eTA is electronically linked to a traveller's passport», the agency says, and adds on the same page «An eTA doesn't guarantee entry to Canada. When you arrive, a border services officer will ask to see your passport and other documents». Three things worth understanding before you pay: (1) it works ONLY if you arrive by plane; by land, bus, train or boat it is not used; (2) it does not allow you to work or study: «An eTA doesn't allow you to work in Canada» and «An eTA doesn't allow you to study in Canada»; and (3) it stays tied to the passport number you applied with, so if you renew your passport, the eTA dies with the old passport. It costs CAD 7 and in most cases is approved within minutes.
We read IRCC's official table of requirements by country on 23/09/2026 (page with modification date 2026-07-31) and split our twenty-eight nationalities into four groups, because the most expensive mistake in this process is being in the wrong group. GROUP 1 — NEED AN eTA (visa-exempt countries, flying): Germany, Andorra, Australia, Chile, Denmark, Spain and Italy. Seven, and they are the same seven that are in the United States Visa Waiver Program: not by chance, but not a rule either, just a coincidence. GROUP 2 — EXEMPT FROM THE eTA: United States. Verbatim from IRCC: «U.S. citizens are exempt from the eTA requirement and must carry proper identification such as a valid U.S. passport». And lawful permanent residents of the United States, since 26 April 2022, are also exempt: they travel with «a valid passport from their country or territory of nationality... and a valid green card». GROUP 3 — eTA ONLY IF THEY MEET AN EXTRA CONDITION (the so-called eTA-X): Argentina, Brazil, Costa Rica, MEXICO, PANAMA and Uruguay. The table shows them as visa-required countries, with the note «Some citizens of ... may be eligible for an eTA if they meet certain requirements». GROUP 4 — VISITOR VISA NO MATTER WHAT, with no eTA option: Bolivia, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Guyana, Honduras, Nicaragua, Paraguay, Peru, Dominican Republic, Suriname and Venezuela. Watch out with group 3: if you are Argentine, Brazilian, Costa Rican, Mexican, Panamanian or Uruguayan and you do NOT meet the extra condition, there is no eTA for you: you need a visa, which costs CAD 100 plus CAD 85 for biometrics and takes weeks.
