Sorry for the delayed response, The visa officer requested the data from Canadian border services. I had to provide the dates and entries and proof of my trips. If it is not possible for you to provide itinerary, then they would have your entry details on your pr card.
The NDVO 2015 spreadsheet is frustrating. First you can't edit on your will, too much admin control. Second there is no reflection on the cases where re-medicals are received and submitted. Please change the way spreadsheet is going!!
