Can apply PR card before its expiry date and question about travelling document

[kuljeetsingh]

Dear Group Members,
My stay period history in Canada is as follows:
• Entered in Canada first time as a landed immigrant (FSW) on 29-May-2011
• Issued PR card on 21-Sep-2011, expiry date of PR 21-Sep-2016
• Left Canada on 03-Dec-2011
• Total time resided in Canada during this tenure : 6 Months
• Entered in Canada on 02-Mar-2014
• Left Canada on 04-Sep-2014
• Total time resided in Canada during this tenure : 6 Months
• Entered Canada on 17-Jan-2015
• Stay in Canada on 17-Jan-2016 : 1 Year (Suppose I dont leave Canada untill 17-Jan-2016)
• Now total time resided in Canada from 29-May-2011 to 17-Jan-2016 : 2 years (730 days)
Now my PR card issue date is different from my landed date, I landed as PR. I have following questions:
• Can I apply my new PR card (application for renewal) on 18-Jan-2016?
• If I leave Canada after 18-Jan-2016 due to some family reasons, Can I be issued a travelling document from my home country CIC visa office after 1 year when I will return to Canada.
Please clear my confusion. Thanks in advance.
