Stratford News Natural gas rates spike tomorrow SHARE ON: Ethan Rabidoux, staff Monday, Mar. 31st, 2014 Don’t forget your natural gas bill spikes 40 per cent tomorrow. Fuel giant Enbridge got permission last week from the Ontario Energy Board to crank up the costs on April 1st. The corporation says the hike is due to a long and bitter winter that has depleted its winter supplies. This increase will cost the average home $400 more each year.
