TORONTO, July 14 (Reuters) - Toronto's main stock index rose on Tuesday morning as a rally in oil and commodity prices helped push the resource-heavy index to its highest level in a week.

Oil company Canadian Natural Resources (CNQ.TO) was the index's biggest heavyweight advancer, up 1.22 percent at C$57.87.
The index's mining-heavy materials sector rose 0.40 percent. Barrick Gold was up 1.03 percent at C$37.25 and Teck Resources TCKb.TO was up 1.42 percent at C$19.29.

"It's a little bit better atmosphere. There was a good move in the market and the commodity market yesterday. It's just follow-through buying today," said Bruce Latimer, trader at Dundee Securities.
Financial shares rose 0.55 percent as Goldman Sachs Group Inc (GS.N) reported a 33 percent rise in quarterly earnings on Tuesday on strong trading results. [ID:nN14175292]
"It's certainly a positive. You see one of the biggest banking firms in the United States come in with some pretty good numbers, it's going to have a spill-over affect on the other financial names," Latimer said.
