TORONTO, Jan 18 (Reuters) - Canada's main stock index fell more than 1 percent on Monday as a rise in Iranian oil production weighed on crude prices and hurt shares in almost every energy stock except Canadian Oil Sands, which agreed to Suncor Energy Inc's sweetened bid.
The Toronto Stock Exchange's S&P/TSX composite index unofficially closed down 131.29 points, or 1.09 percent, at 11,942.17. All 10 main groups fell, with energy stocks off 2.5 percent.
