Toronto's main stock market index fell on Thursday after a two-day rally as a drop in oil prices from six-month highs pressured energy shares. Oil fell to settle at $61.05 a barrel from Wednesday's half-year high above $62 as signs of job market weakness fanned concerns about economic recovery. The TSX index's energy sector fell 4.4 percent, with EnCana Corp down 5.6 percent at C$58.76. Suncor Energy fell 3.83 percent to C$34.87. Toronto also followed world stocks lower as several US economic reports fuelled doubts about a quick economic recovery, while Standard & Poor's revised its UK ratings outlook lower, stoking concern that Washington's growing deficit could lead to a credit rating downgrade for the United States.
