Thanks Leon for quick and to-the-point answers

Thus, 5-years time limit starts from the issue date of PR-card in Canada. I got it right ?
If PR-visa validity expires, then the applicant has to re-apply for immigration or ?
In order to keep PR status, the stay duration is two years out of five? or 3 out of 5? I am confused because I read that it is 3 years for applying citizenship and 2 years to renew your PR-Card for next 5 years?
Thanks again
PS: i got it, rather than using the word "land", probably, i should have used the word "enter"


but "land" gives a
smiling look, isn't it?
