What would you recommend a exchange student going to Quebec?

Im going to Quebec, Quebec next semester. I would like to know some tips and suggestions. I live in Hermosillo, Mexico were the normal temperature is above 110ºF or 45 celsius, so Im afraid Canada is too cold for me :S. Also would like to know places I must see and things I should do. What gear should I bring with me. How expensive is food there? What can I do to save a couple dollars? Any ideas would be appreciated. Thanks :D
