You can buy ticket at bus terminal of bay street(close to metro station bay), one way ticket is around cd 70's. Every person is allowed to bring two luggages.You'd better take the first bus in the morning, you will arrive montreal(Metro station berri Quam) around 2 pm.
If you want to buy cheap ticket, you can send to poster at some web site to find somebody can give you a ride.
Good luck.
