The short answer: on a trip that mixes flights and driving, Canada asks for an eTA only for the flight that brings you into Canada (or through a Canadian airport). Fly into Toronto or Vancouver and drive on to the US, and you need the eTA before you board; fly into New York or Seattle and drive north, and the Canadian side needs only your passport, unless your passport requires a Canadian visitor visa (which includes the passports that can use an eTA only by air), in which case the car crossing needs that visa. Plan the paperwork leg by leg, and if any leg is a flight into Canada, apply for a Canada eTA before you book it. That link leads to a paid private service, separate from the Government of Canada.
Applying directly on canada.ca costs only the government fee. One eTA is tied to one passport and lasts up to five years, so it covers your first flight and any later return by air. It does not guarantee entry: the officer at the border still decides.
The United States has its own rules at every crossing: ESTA or a visa applies even by land, as what a day trip across the Niagara bridges needs shows for a short hop. This page covers longer trips that mix planes and cars.
Which legs of a Canada–US trip need an eTA?
The eTA is permission to fly into Canada or to connect through a Canadian airport; no one asks for it when you come in from the US on the road, by bus, on an Amtrak or other train, or on a cruise ship. So for each route, ask which legs are flights into Canada. US citizens need no eTA on any route below.
| Route | Visa-exempt passport (UK, EU, Australia) | Passport that can use an eTA only by air (Mexico, Brazil, Philippines) | Visa-required passport | US side |
|---|---|---|---|---|
| A. Fly into Canada, drive to the US, fly home from the US | eTA for the first flight | eTA for the flight, if you qualify; otherwise a visitor visa | Visitor visa | ESTA or visa before the land crossing; electronic I-94 |
| B. Fly into the US, drive into Canada, fly home from Canada | No eTA for the drive in | Visitor visa for the drive in | Visitor visa | ESTA or visa for the flight in; keep proof you left the US |
| C. Fly into Canada, drive to the US, drive back into Canada, fly home from Canada | eTA for the first flight; nothing new at the crossing back | eTA for the flight in; driving back without a visa only under a two-part condition (see below) | Visitor visa; a single-entry one: you can ask to reuse it under the same condition | ESTA or visa at the land crossing |
| D. Fly into the US, drive into Canada, drive back, fly home from the US | No eTA at all | Visitor visa | Visitor visa | ESTA or visa again on the way back |
| E. Any route with a flight from the US into Canada | eTA for that flight | eTA if you qualify, otherwise a visa | Visitor visa | None |
Route E is the one people miss: drive to Seattle, fly Seattle to Toronto, and that flight is a flight into Canada like any other.
Flying into Canada and driving out to the US: what changes at the border?
The airline checks the eTA before you board the first flight, and a new passport means a new eTA. If your first stop is Vancouver, what happens after you land at Vancouver airport walks through the arrival itself.
After that, the American side takes over. According to US Customs and Border Protection (CBP), ESTA must be approved before you reach a land border port of entry. At a land crossing the I-94 is issued electronically and the officer does not hand you a paper slip; the CBP Link app and the I-94 website let you begin it in advance.
For the two systems side by side, see how the Canada eTA and the US ESTA differ.
Flying into the US and driving into Canada: what does the border officer ask for?
With a visa-exempt passport (most of Europe, Australia, New Zealand, Japan), the Canadian land crossing asks for your passport. Nobody asks for an eTA, because you are not arriving by air. The Canada Border Services Agency (CBSA) calls the passport the one document that is reliably accepted everywhere, and the officer decides whether to admit you.
Passports on the conditional list work differently. Seventeen countries, including Mexico, Brazil, the Philippines, Thailand and Argentina, can hold an eTA in place of a visa if the traveller has held a Canadian visitor visa in the past 10 years or holds a US non-immigrant visa that is valid on the day of applying, and only when they fly to or connect through a Canadian airport. Come in on the road, by rail or on the water, and a visitor visa is required. For a trip that mixes flying and driving, IRCC calls a visa the best option, since it gives the most freedom. This is the costliest mistake in the topic, and easy to make because the same person flying into Vancouver is fine. Check Canada’s list of passports that can use an eTA only by air before you plan the drive. If your passport requires a visa, you need the visitor visa whichever way you arrive.
The flight home from Canada is where the published rules go quiet. Canada’s requirement is written around flying into the country or changing planes at a Canadian airport, and it does not address a flight that departs from Canada. This page draws no conclusion on that point, so ask your airline which documents it will check. What is certain is the reverse: a later flight into Canada, for example one that leaves from a US airport, needs the eTA.
One tip from CBP: when you leave the US by land, the exit may not be recorded in your I-94, and a traveller can ask the CBSA officer for an entry stamp on arriving in Canada.
Driving back into Canada after a few days in the US: is a new visa needed?
With a visa-exempt passport this is the easy case. You show the passport, no eTA is asked for, and the same eTA stays valid if the trip later ends with route E.
For passports that can use an eTA only by air, canada.ca sets a rule worth knowing before you cross south. Once you are inside Canada, a trip straight to the US (or to Saint-Pierre and Miquelon) and straight back, by road or by air, needs no visitor visa, as long as you return within your authorized stay. Go anywhere else first, and you need an eTA to return by air or a visitor visa to return overland or by water.
With a visa-required passport, a single-entry visa holder can ask to return on the same visa only if the trip covered the US or Saint-Pierre and Miquelon alone and ends before the approved stay runs out; otherwise a new visa is needed. A multiple-entry visa works until it expires. The officer makes the final call, including how long you may stay, so do not assume a fresh six months. Drivers often ask about this part alone; see how the eTA rule works for drivers at a land crossing.
What if you fly into the US, visit Canada and drive back?
Route D is the simplest. Canada asks for no eTA, because nothing in it is a flight into the country, though the visa rules above still apply. ESTA or a visa applies again when you cross back into the US. How a side trip to Canada counts toward the 90-day ESTA clock is a question for CBP.
Can you rent a car in Canada and drive across the border?
Generally yes, according to the large rental companies, with conditions that vary by location and vehicle. Settle these before you sign:
- Tell the company you plan to cross; some vehicle classes, such as large passenger and cargo vans, cannot leave the country.
- Ask about one-way rentals between Canada and the US, which depend on availability and are usually requested in advance at participating locations.
- Rental companies issue the insurance paper for taking a US-plated car into Canada, and some hand it over at the counter.
- Ask whether driver or plate rules apply. One major company says a Canadian resident returning a car in the US may need one with Canadian plates.
- Keep the rental agreement and insurance documents in the car.
On the Canadian side, a visitor may bring a vehicle in temporarily for personal use without paying duty, and must take it out by the declared departure date, no later than 12 months after it arrived.
What should you keep in the car at the crossing?
- The passport your eTA was issued on, if you flew into Canada.
- A visitor visa, if your passport needs one.
- ESTA approval or a US visa for the American crossing.
- The rental agreement and the insurance card.
- Your onward flight booking, and a CBSA entry stamp if you asked for one.
Unsure that your approval is still active? You can check your eTA status with your passport and application number or UCI.
The short version
- On a Canada–US trip, only a flight into Canada, or through a Canadian airport, needs an eTA.
- Fly into Canada, drive to the US: eTA first, then ESTA or a visa for the land crossing.
- Fly into the US, drive into Canada: no eTA, but a visitor visa for passports that use an eTA only by air.
- Driving back into Canada from the US can be possible without a new visa under two conditions; the officer decides.
- A flight from the US into Canada brings the eTA rule back.
- One eTA per passport covers every flight in for up to five years, or until that passport expires.
FAQ
Do I need an eTA to enter Canada from the US? By land or sea, a visa-exempt passport needs no eTA, only the passport. Passports on the conditional list need a visitor visa for a car crossing, unless they are coming back directly from a US side trip within their authorized stay. By air from the US, the eTA is required. US citizens do not need one in either case.
What is needed to enter Canada from the US by car? A passport, which the CBSA calls the document reliably accepted by everyone. Add a visitor visa if your passport needs one, and for a rental, the agreement and the insurance card. A US lawful permanent resident presents the green card together with the passport of their own nationality, both unexpired.
Can you rent a car in Canada and drive across the border? According to the large rental companies, usually yes, and most cars may leave the country. Tell the company beforehand, because some vehicle classes are excluded.
How to rent a car in Canada and drop off in the USA? Ask for a one-way rental between countries before you book. It depends on availability at participating locations, and some companies set rules for drivers or plates. Compare the one-way terms when you book.
Do I need an eTA for connecting flights? Yes, if your passport is eTA-eligible and the connection is at a Canadian airport; a visa-required passport needs a visa instead. On a trip with a flight from the US through Canada or into it, that is where the rule applies.
