at the check-ins when you go they will type her passport # to verify it's her ticket, would not anything pop up to say that she is over her stay? I'm assuming the system would not know about the implied status or would it? Our trip is in Jan and her expiry date is Dec 21. I mean I will do my homework and take with me the proof of application submitted and received date just in case.
As a former airline agent that worked many years at the airport , nothing pops up when passport data is input into the system . Only time anything will pop up is if the passengers destination country requires a electronic visa, and they are not holding one .As well if the passport has expired. That passport information however is shared with numerous countries, as well as the Canadian Government when you are leaving . That’s how sometimes the government can tell you overstayed . There’s no exit controls , but information is sent to the IRCC, and matches information the passenger gave when either entering the country as well as when applying for the visa
