TORONTO, Sept 23 (Reuters) - Canada's benchmark stock index fell on Friday, with energy stocks slipping on slumping oil prices as skepticism grew that a deal to curb output can be struck next week and investors broadly pulled back after a strong rally earlier in the week.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE unofficially closed down 99.25 points, or 0.67 percent, at 14,697.93. Eight of the index's 10 main groups ended lower.
