Heat, Hydro and Water Expenses?

Hey, So I just got a house to rent finally. I have been living in an apartment for the past 4 years and have never had to pay for this stuff. I just want to the the "average" per month. And how often you get billed for these. I live in Ontario, Canada. I would greatly appreciate someone to help me out. This will be my first time going through all of this stuff.
