Is my budget for University of Calgary enough?

I have a very strict budget of 25k CAD for my first year of undergraduate studies. I would also like to know from fellow international students a best estimate of finances each year in Calgary.

From the University of Calgary web site:
“For an estimate of academic costs for one or two terms as an international undergraduate student, we recommend you try the University’s online cost estimator tool.”

Their cost estimator web site appears to be having difficulty right now, but hopefully will be okay soon.
