Electricity rates are the same across Ontario, and natural gas prices are mostly the same. I live near Toronto, and when I did the math a couple of years ago, an electric heat pump water heater would cost about 4x more to run than natural gas (back-of-the-envelope math). A resistive water heater would be even worse.
