  1. A family of four, including a baby, visits the UK. How many ETAs do they need?
    Show the answer

    Four, one per person. Each traveler needs their own ETA, even babies and children. There is no family ETA. Apply only on the official GOV.UK site or app, because copycat sites charge more.

  2. A US citizen flies to Toronto. Do they need a Canadian eTA?
    Show the answer

    No, US citizens are exempt. Canada's eTA is for travelers from eTA-required countries flying in. US citizens are exempt, but must carry proper identification such as a valid US passport.

  3. A traveler from an eTA-required country needs a Canadian eTA when arriving which way?
    Show the answer

    By air. Travelers from eTA-required countries need an eTA to fly to or transit through a Canadian airport. They generally do not need one when arriving by car, bus, train or boat, including a cruise ship.
