Do I need a new eTA for Canada if I change my passport?
If you receive a new passport, you'll need a new eTA. Your eTA is connected electronically to your passport. Most international travelers need an Electronic Travel Authorization (eTA) to fly to, or transit through, a Canadian airport.
Since 2016, Canada eTA has become an obligatory entrance requirement for visa-exempt foreign individuals traveling to Canada by air. The permission is electronically connected to your passport and is good for five years, or until it expires, whichever occurs first. An eTA can be used for transportation, leisure, or business trips lasting up to six months.
An approved eTA validates a foreign national's authorization to come to Canada without a visa and serves as a waiver document. While a visa waiver, such as the eTA, serves nearly the same purpose as a visa, the process of acquiring one differs significantly from that of obtaining a visa. Applying for a conventional Canada visiting visa takes longer, however, eTA applicants are often notified of a decision within a few days.
