Not at all, so many guys do that. My brother did the same.Are you sure about that "you will be in compliance as long as you are out of Canada less than 1095 days (from your date of first landing)."?
He clearly said that he left after receiving the PR. He will be questioned about the reasons to go out once he come back to Canada right? Or he will only be questioned about his RO after 5 years to check his Residence Obligations?
