A friend's daughter is going to Montreal as a exchange student in August. She would like to find out whether there is free wi-fi at the airport and whether there is a kiosk for selling prepaid SIM card so she could contact a friend to pick her up. If there is a SIM kiosk, it it near the International exit?

I think it's highly likely there's be SIMs for purchase.
