Sorry for asking another question. It's based on this comment: "If he exits and enters again after a few days, it totally depends on the IO at the border. The proper way would be to apply for extension which you should do when he has 30 days left on his visa and takes currently 101 days, see http://www.cic.gc.ca/english/information/times/canada/process-in.asp#temp_res After his 6 months were up, he would have implied status and after the 101 day processing, he would have a yes or a no. That is what happened to that other couple, they got a no and after talking to the border services, they were advised by them apparently to go to the US and come back so that's what they did and in their case, it worked." --> On this last statement (hopefully in red), was the person asking for an extension as a visitor or student???
