Citizenship and Flight Date - Worst-Case Scenario!!!


New Member
My Wife is currently PR and in Canada, waiting for her Citizenship to be completed
She already passed her Online Test and several categories have already been completed

She wants to purchase a flight to her home country as early as possible (cheapest price)
This means she needs to provide her current non-Canadian Passport info

If her Citizenship is completed before her flight - She needs to get a new Canadian Passport
What do we do with the Passport info provided in her Plane Ticket?

Just thinking of the worst-case scenario - if all the timing becomes tight
What happens if Her Citizenship, and flight date all come at the same time!?
