If you look at a different area of immigration law where this is looked at, when a Canadian citizen wants to sponsor a spouse to come to Canada but the Canadian is not living in Canada, it's part of the process that they have to prove they intend to move back once the spouse gets a permanent resident visa. Visa offices often do this. They write a letter telling the Canadian to show them whatever evidence they have that they're really making plans to relocate. They put them to the proof of it. They ask if they've started looking for a job, started looking for accommodation, started transferring money over, if they have family in Canada and those kinds of things.
