* TSX rises 37.36 points, or 0.29 percent, to 12,772.48 * Nine of the 10 main index sectors advance * Suncor has biggest positive influence on index * Air Canada jumps after load factor results By John Tilak TORONTO, Oct 4 (Reuters) - Canada's main stock index advanced on Friday as investors brushed aside worries over the U.S. government shutdown, with gains in the energy and financial sectors supporting the market. As Tropical Storm Karen moved through the Gulf of Mexico, affecting U.S. energy output, the price of oil rose on supply concerns. Shares of energy companies climbed and had the biggest positive impact on the index. With the U.S. government shutdown dragging into a fourth day, investors watched closely as Republican members of the House of Representatives got together to chart their next course of action. But the market appeared to shrug off fears that lawmakers will fail to resolve the budget crisis and prevent a debt default. Rick Hutcheon, president and chief operating officer at RKH Investments, said the TSX will tread water until the U.S. political situation is resolved but will make gains as the economy improves and commodity prices stabilize. "Everyone is sitting on their hands, waiting for Washington to make their move," he said. "They'll have their bickering and fighting, but ultimately they'll come to an agreement." "I don't see it having a huge impact on Canada," he said, but added that the longer the U.S. impasse lasts, the more negative it could be for the Canadian market. The Toronto Stock Exchange's S&P/TSX composite index was up 37.36 points, or 0.29 percent, at 12,772.48. Nine of the 10 main sectors on the index were higher. Financials, the index's most heavily weighted sector, advanced 0.3 percent. Royal Bank of Canada rose 0.4 percent to C$66.23, and Toronto-Dominion Bank was up 0.4 percent at C$91.53. Energy companies climbed, with Suncor Energy Inc added 1.2 percent to C$36.67, playing the biggest role of any single stock in leading the market higher. Canadian Natural Resources Ltd rose 0.6 percent to C$31.96. Air Canada jumped about 10 percent to C$4.37 after it reported load factor results late on Thursday.
