I think I posted this last year in a thread about Patrick White.
1 - Trying out for the Canucks means he has to pay for housing wherever the Canucks are having training camp. He also has to pay out of his own pocket to get there, as well as food, equipment sharpening etc. The same applies to any player who is on a NCAA roster, or is going to join a NCAA team.
2 - Travel expenses if he get dressed for an pre-season exhibition match not in GM Place.
3 - U of Minny will have started school by then, and will be around midterms, and I think their hockey season will have started as well.
