thank you scylla.
but I'm confused, because I've heart many times that as long as one person of a couple (both pr) stays in Canada, the other will always be able to keep his/her prship.
Now you're telling me that this is not the truth -- are you sure about that?
I am sure about that too. There are limited ways you can keep your PR while living outside Canada.
1) You are married to a Canadian citizen and they are living outside Canada with you.
2) You as a PR get a job working for a Canadian employer and this employer transfers you to a full time position outside Canada.
3) You are the spouse or minor child of PR who qualifies under 2) and you are living with them outside Canada.
As none of these conditions apply to your father, he can only stay outside Canada up to 3 years (1094 days) in any 5 year period. Otherwise he risks losing his PR. However, if he loses his PR, as long as your mother is living in Canada and meets the RO (residency obligation) herself, she can sponsor him back.
As for citizenship, time outside Canada does not count for citizenship except with one exception and that is when you are a PR living outside Canada with a Canadian citizen spouse who is posted outside Canada working for the govt. or armed forces.
