The short answer: you don’t need an eTA to walk or drive across to the Canadian side of Niagara Falls. The eTA is only for travellers flying into Canada; at the bridge, what matters is your passport and, for some nationalities, a Canadian visitor visa. Visitors from Europe, the UK, Australia and other eTA countries need only a valid passport. Americans need proof of citizenship, and a passport is the safest choice. Anyone whose passport requires a Canadian visa needs that visa even for an afternoon at the falls.
The picture changes if a flight is part of the trip. Say you land in Toronto and drive to the water, or change planes at a Canadian airport on the way home: then an eTA is needed before you board. The place to apply for a Canada eTA is get-eta.com, a paid private service, separate from the Government of Canada. Your journey back to New York is checked under US rules, which get their own section further down.
Whether you belong in the “passport only” group or the “visa first” group comes down to nationality, and our comparison of an eTA and a visitor visa explains who falls on which side. The rest of this page follows a traveller who starts in New York or Buffalo and heads for the Canadian side.
Canadian side of Niagara Falls: what each passport needs
An eTA is an air-travel authorization. Crossing the Rainbow Bridge into Canada, whether on foot, by car or on a coach, counts as arriving by land, so the eTA does not enter the picture. Here is how it works out for each kind of traveller.
| Walk or drive across from the US | Fly into Canada | |
|---|---|---|
| US citizen | Passport recommended; otherwise ID showing name, birth date and citizenship | No eTA; passport |
| US green card holder | Green card or equivalent proof of status; no passport required | Green card plus passport |
| Passport from an eTA country (UK, Germany, Australia and others) | Valid passport; no eTA | eTA plus passport |
| Visa-required passport with a US visa, from a country such as Brazil, Mexico or the Philippines | Canadian visitor visa | An eTA may replace the visa |
| Any other visa-required passport (India, China, Nigeria and others) | Canadian visitor visa | Canadian visitor visa |
An officer still makes the final call at the booth, because neither an eTA nor a visa guarantees entry. For a short plain-language take on the same question, see this short answer on driving across the border.
Can I go to the Canada side of Niagara Falls with a US visa?
This is the question travellers from outside the US and Canada ask most often, and the answer is no: a US visa does not open the Canadian border. If your passport is on Canada’s visa-required list, you need a Canadian visitor visa for any way of entering, including a car, bus, boat or a train such as the Amtrak Maple Leaf from the United States.
A visitor visa is requested online. The government fee is 100 CAD, biometrics cost another 85 CAD when they are required, and processing times differ by country. That is why the visa has to be sorted out well before the day trip, not on the morning you plan to cross.
There is one special case. Citizens of a short list of countries, among them Brazil, Mexico, the Philippines and Thailand, can get an eTA instead of a visa when they hold a valid non-immigrant US visa (or had a Canadian visa in the past ten years) and travel to Canada by air. The same rule says those travellers need a visitor visa if they come from the US by car, bus, train or boat. The conditions are laid out on the eTA-instead-of-a-visa page, and our guide to how a US visa changes the rules when you fly covers the flying side.
Two more points help here. You never need a visa and an eTA together: it is one or the other. And if you expect to move between the two countries in several combinations, Canada’s own guidance says a visa gives the most flexibility.
Can you go to the Canadian side without a passport?
For almost everyone the honest answer is no, but there are exceptions worth knowing.
- US citizens. A passport is recommended because it is the only document accepted everywhere. If you do not have one and you are not flying, you can show identity documents that together give your full name, date of birth and citizenship. If you wonder whether a REAL ID driver’s licence works, apply that test: does the document, alone or with another, show all three details? A passport removes the doubt.
- US green card holders. Arriving directly from the US by land or water, you only need your green card or an equivalent proof of status, and you don’t need to present a passport. Flying in, you need the green card and a valid passport from your country of nationality.
- Everyone else. A valid passport is required, whether your country is on the eTA list or the visa list.
Children on the bridge
Children under 18 follow the same document rules as adults. A child travelling with one parent should carry a copy of the birth certificate and a letter of permission from the other parent. A child going with an adult who is not a parent needs written permission from the parents.
Getting back to New York: ESTA and the I-94
These are US Customs and Border Protection (CBP) rules, so read this section as a heads-up and check the current details with CBP before you go.
- ESTA. Travellers on the Visa Waiver Program need an approved ESTA before they reach a US land border, not just before boarding a plane. So a European who is heading back into the US over a bridge on the Visa Waiver Program needs a valid one in hand. An ESTA does not settle admission either: the CBP officer decides on the spot.
- I-94. At a land border the I-94 record is electronic, and no paper slip is handed out. CBP suggests filing it ahead of time through the CBP Link app or the I-94 website, and the process may involve a fee, so check CBP for the current figure.
- Proof that you left. If you entered the US by air with an electronic I-94 and then leave by land into Canada without coming back (for example, you fly home from Toronto), your departure may not be recorded. Keep evidence of the exit, such as tickets or receipts, and you can ask the Canadian officer for an entry stamp.
- US visa holders. Make sure your visa still allows you to re-enter the United States on the day you come back.
Flying via Toronto: when the eTA comes back into the picture
A flight changes everything. If you land at Toronto from overseas on an eTA-country passport and then travel to Niagara Falls, Ontario, you needed an eTA to board that flight. A connection at a Canadian airport on your way home to another country is the same: air transit through Canada requires an eTA, while passing through by train, bus or boat does not.
There is also a handy reverse case. If you are already in Canada as a visitor and make a quick trip to the American side, you can usually return without a new visa or eTA, as long as you go straight to the US and straight back, and your permitted stay has not run out.
The eTA carries a government fee and is linked to one person and one passport. Many applications are approved within minutes, while some need several days; in that case an email with the next steps arrives within 72 hours of applying. Use the same passport for the application and for the flight, and compare the passport number in your approval email with the one printed in the document. If they differ, apply again. To see where an application stands, the page to check your eTA status asks for your passport together with your application number or UCI, not the passport alone.
Applying on canada.ca costs only the fee.
FAQ
Do you need a passport to go to the Canadian side of Niagara Falls? Most travellers who are not US citizens need one. The exception is a US green card holder crossing by land, who needs only the card. US citizens are advised to carry a passport, and without it they can show documents with their name, date of birth and citizenship when not flying.
Do I need a visa to visit Niagara Falls, Canada from the US? It depends on your passport, not on where you start. A visa-required passport needs a Canadian visitor visa even at the bridge, while a passport from an eTA country needs only the passport by land.
Can I go to the Canadian side of Niagara Falls with a REAL ID? For a US citizen not flying, the test is whether the documents show your name, date of birth and citizenship, and a passport settles it.
Do I need an ESTA to visit Niagara Falls from Canada? Not for the Canadian side. For coming back into the US by land, a Visa Waiver Program traveller needs an approved ESTA, and the I-94 is issued electronically.
Can I use an eTA to enter Canada by land? An eTA is not asked for at a land crossing, and a valid passport from an eTA country is enough. If you got an eTA on the strength of a US visa, it does not stand in for a visa on the bridge.
