To apply for an eTA you must be a citizen of a country that is visa-exempt for example, UK or
Australia. You can see the full list of countries
. Applying for eTA takes just a few minutes
but you will need to have a valid passport and have your details ready to enter into the online
form. You will also require a debit or credit card to pay the application fee for the Canada
transit visa. If you are not from the visa-exempt countries then you will require a Temporary
Resident Visa for transit.
