Now about housing.. First you will probably be on a STUDENT VISA, which means you ARE NOT ALLOWED TO WORK HERE!!!!!!!
If you do want to work here you MUST apply for a WORK VISA as well (This may not be easy to get, you were probably told when you got your VISA that you must have enough money to survive and pay for all expenses when you come. I am sure they gave you an amount to budget for. My QUICK estimate would be about 1200/month PLUS tuition, books, and entertainment. I think that would allow you to live in a nice enough place and have more than enough for food.
If you are living as a group (shared accomodation and food) I am sure you can cut that down a good bit. I have survived on much less during college.
Your books will be between $80-$200 although it is VERY unlikely you will have any over $150. You can generally buy used books for about 75% the new price or even 50% if you buy them from previous students of the course.
I just checked out the centennial website and I saw they have a lot of support for international students.
Those support services include housing. There are residences on campus but they will be expensive. To get information on that you can contact the school, WHILE it will be a little more expensive it may be a good idea for the first year you are here.
If you would like to find off campus housing than go to

or try and call the university they may have someone on staff who can help you rent a whole house.
You should easily be able to find a place for around $500/Bedroom Maybe $400
Here is a link to our real-estate listings with properties for rent in the nearby area of the college
