Ontarians who heat their homes with natural gas are about to get hit in the pocketbook. The Ontario Energy Board has approved a request by Enbridge Gas to hike rates by 40 per cent.  The rate increase comes into effect April 1st, but the utility says most people won’t notice the pinch until next winter.  Enbridge says the hike is needed to help it recover costs following the harshest winter in 25 years.
