Even if your tickets are real, they may not be valid. You won't know until you have them scanned at the doors.
I would only consider buying tickets from Season Ticket Holders, but even doing so there's a risk involved. If a STH sold you their tickets, all they have to do is call their account rep and say they've lost their tickets for the game. The tickets they sold you will become void and they'll now have new tickets and your money to go to the game with.
All Season Ticket Holders should have a Canucks Card, not sure if this season's have been mailed out yet, but last year's was a White and Green card with the ticketholder's name on it. If they have nothing to hide they shouldn't have a problem showing you this card.
The only for sure way to be guaranteed good tickets is to buy them from Ticket Master, Stub Hub or Prime Seat Club.
