Thanks. Did you use this method yourself, or are you merely suggesting ?
Another person suggested to me that I create a shipping label for the return now and choose a ship date that's 1-2 weeks ahead from now, with the assumption that if CIC mails after the mentioned ship date, it will just get updated in FedEx's system. Not sure how correct is this info, however this is what another member suggested I do.
Hi, apologies for the late reply. I am telling this from personal experience. At least in my area, I was told that Fedex cannot generate a return shipping label for an international shipping. Same with UPS.
You require landing paper and passport.
If you are already in Canada on work permit/visitor permit, it is safer to bring those documents also. Also, please note down your previous SIN number (if available).
If you are coming from outside of Canada, make sure you have full postal address, where you are planning to stay. Address proof is not required. But, if you have leased or rental agreement, it is safer to bring.
