The Canada eTA Requirements are relatively simple for eligible travellers. You normally need a valid passport from an eTA-required country, an email address and a suitable payment card to complete the online application. You will also need to answer questions about your personal and travel information. The eTA is electronically connected to the passport used during the application, so the passport number must be entered accurately. An approved eTA allows you to travel to Canada by air, but it does not guarantee entry. At the border, you may still need to satisfy an officer that you meet Canada’s entry requirements, including having sufficient funds and plans to leave Canada at the end of your visit. Travellers should always check their eligibility before applying because visa and eTA requirements vary by nationality and travel circumstances.
