This depends on so many things...the square footage of the home...how well insulated it is...how many people in your family...and most of all, where you live. I have a 4 bedroom house in Ottawa and spend about $100 + for water, $100 hydro and gas ranges from about $30 in summer to $200+ in winter (all these figures are monthly). You should be able to get these figures from landlords who are advertising homes for rent, so it might just take some calling around.
