New to everything

Hi, I'm new to mcmaster. I don't know the nature of the academic life in Canada at all, so I have a lot of questions :

I saw there is a meal card, where can I make one of these?

Also, I'm in ITB, and don't know how to book a locker and where to keep my stuff. I have an access to the gradute students room, but don't know other places to study in the campus.

If you have any additional information about anything, please go ahead and tell me. Thanks
