Once you have applied for an eTA you can check on the status at any time. This includes when you
are waiting to receive confirmation of whether your application has been approved or also to check at
any time whether an existing eTA is still valid.
To check that your eTA is valid, you simply need to confirm your application number, passport number,
country of issue and issue and expiry date. You will then be able to view the status of your eTA.
eTA is valid for a period of five years
but if your passport runs out before then, you must
apply for a new eTA at the same time as a new passport.
