There is no issue for PR status also we got AOR for citizenship application as well, the only issue here for PR process time since we planed to travel with in 1 month so want to make sure it could be renewed timely, we have to buy air tickets that would cost around $7k in order to proceed with urgent process
Even so, you don't know how long you going to be stuck there and you want to travel urgently. Or you can have your spouse wait in Canada for the renewed PR card, after it is issued, travel with the rest of the family (with your renewed card) to visit the sicked grandma.
