he has to officially declare that he's leaving school to turn pro, even to test the waters, since you cannot have an agent while in the NCAA.

basically if he wants to test the arctic waters he can't go back to school. and there would be no incentive to do so, since his stock is at an all time low. the only reason he'd leave is to get onto a better team which will help with his development, and there's no reason he wouldn't go with the canucks, since we have one of the best AHL teams in the league right now, and he would make it better.
