It's official, the McGuinty Government will give residents a 10 percent rebate on electricity bills in 2011. Minister of Northern Development Michael Gravelle says it will start in January. Gravelle adds if companies are unable to provide the rebate on the bills in January, the rebate will be retroactive to January on future bills. The opposition parties say the Liberals are trying to buy voter support, but Gravelle says that's not the case.
