Re: Pick up PR card @ CIC office
If you are renewing your PR card, then they will ask you to bring your original documents to show them. This means all passports used in last 5 years from the date you applied, originals of notice of assessment ( tax), COPR, PR card, Health card, Driver's Licence.
The officer in charge will match the passport stamps with information you supplied in your application form.
It is a good idea to prepare an excel file printout of your entry /exit dates and which passport page each entry /exit stamp is located. This helps officer when they are matching the information.
Also suggest you to make small notes for reason of travel for each entry/exit. Sometimes officer also asks why you had traveled. If they cannot match the information due to missing passport, then they can refuse to give you the new PR card. So most important is to take along all your passports which you used in that time period.
