TORONTO, May 20 (Reuters) - The Toronto Stock Exchange's main index climbed further into record territory on Tuesday, thanks to soaring oil prices which boosted energy shares.

Overall, the sector, which accounts for almost 30 percent of the index, gained 3 percent, as the price of oil hit a new high near $130 a barrel amid bullish price forecasts and tight supplies of refined products.

Shares of Petrobank Energy and Resources (PBG.TO: Quote, Profile, Research, Stock Buzz) jumped C$2.90, or 5.2 percent, to C$58.36 after a report that India's Oil and Natural Gas Corp (ONGC.BO: Quote, Profile, Research, Stock Buzz) was getting ready to make a bid for a Canadian oil producer. A Petrobank executive dismissed speculation his company was the target.
