TORONTO, Oct 23 (Reuters) - Canada's main stock index posted a sharp gain on Thursday as the market rebounded from a selloff in the previous session, when worries about shootings in Ottawa weighed, and as energy shares jumped with the price of oil. The Toronto Stock Exchange's S&P/TSX composite index unofficially closed up 174.76 points, or 1.22 percent, at 14,486.83. All of the 10 main sectors on the index were higher. (Reporting by John Tilak)
