TORONTO, Jan 7 (Reuters) - Toronto's main stock index was 2.6 percent lower at midday on Wednesday, led down by oil and gold shares as commodity prices dropped and as a bout of profit-taking set in after six straight sessions of gains.

The energy sector was down 4.7 percent as the price of oil slumped more than $3 a barrel after a U.S. government inventory report showed supplies rose more than expected. Oil company EnCana (ECA.TO: Quote, Profile, Research), the index's biggest mover, shed 4.8 percent to C$57.93.

Gold issues fell with the price of gold, which slipped more than 3 percent. That weighed on the materials group, which dropped 3.4 percent. Barrick Gold (ABX.TO: Quote, Profile, Research) was down 4.3 percent at C$38.09.

The heavily weighted financial sector was also a drag, down 2 percent, led lower by Manulife Financial (MFC.TO: Quote, Profile, Research) and Royal Bank of Canada (RY.TO: Quote, Profile, Research). Manulife, Canada's biggest insurer, fell 3.8 percent to C$23.19, while Royal, Canada's biggest bank, lost 1.7 percent to C$37.39.
