Thanks Masafiri and Meyakanor I got clarity on CBSA now after this discussion. So entry stamps do carry value otherwise CIC wont be requesting CBSA reports just for nothing. They have tool and methods to check other criteria of falsifying.
My next question to all of us is:
if someone is self employed for lets say 1090 days and last 5 days he got a full time job with reputed company does it mean his journey to citizenship will become at ease with less chance of RQ. Its like you are fighting in a ring and getting punched from your opponent and last 2 minutes of the match is crucial and somehow you get God power or will power to fight back and you win the match. Will CIC consider your current situation as reason for your stability and ties to Canada.
