Electricity rates in Ontario have officially gone up. Starting Tuesday, residents will pay more for their electricity. A typical household, using about 800 kilowatt hours per month, will see an increase of about $6.00, while those with smart meters will go up by about $4.00. According to the Ontario Energy Board, increases are needed as coal-fired generation is replaced by nuclear, natural gas and renewable energy. Energy Minister Chris Bentley says the spike is to reflect the cost of upgrading the province’s energy system.
