You've now posted the same info three times responding to old - in some cases quite old - posts.Hi,
if you renew your PR card before expiry and its approved. you can still use your old PR card to enter into Canada as per rule old PR card is valid upto 60 days for travel.
old PR card will become invalid for travel after 60 days.
We get it.
But since you've only posted three times and keep repeating the same information, the likelihood is you may be a spammer and you'll get twigged for it soon.
If you're not a spammer: thanks, but no need to keep repeating the same info and responding to posts that are more than six years old.
