TORONTO - The Toronto stock market closed lower Thursday as U.S. data showing falling oil and gasoline demand raised worries about economic weakness.

The S&P/TSX composite index declined 78.99 points to 11,360.76.

The TSX energy sector was down 1.44 per cent. The December crude contract on the New York Mercantile Exchange moved down $2.34 to US$76.94 a barrel as the U.S. dollar strengthened and the Department of Energy said U.S. crude supplies rose by 1.8 million barrels while gasoline inventories jumped 2.5 million barrels last week. Canadian Natural Resources (TSX:CNQ) fell $1.29 to C$69.47.

EnCana Corp. (TSX:ECA) shares moved $1.45 lower to $59.25 as the energy giant reported that its third-quarter net income fell to $25 million or three cents per share, down from $3.5 billion or $4.73 per share a year earlier. It added that hedging activities softened the blow from lower commodity prices. Operating earnings, which include realized hedging gains and losses, fell to $775 million or $1.03 per share, down from $1.4 billion or $1.92 per share.

The gold sector stepped back 2.09 per cent as a rising U.S. dollar helped push gold prices lower from Wednesday's latest record close with the December contract in New York off $8 to US$1,106.60 an ounce. Barrick Gold Corp. (TSX:ABX) fell 82 cents to $44.25 while Kinross Gold Corp. (TSX:K) was off 67 cents to $19.83.

December copper stepped back 1.85 cents at US$2.95 a pound and the base metals sector declined 3.09 per cent. Teck Resources (TSX:TCK.B) declined $1.15 to $33.02 and HudBay Minerals (TSX:HBM) fell 76 cents to $15.74.

The Canadian dollar moved down 0.54 of a cent from Tuesday's close to 94.69 cents US.

The TSX Venture Exchange slipped 3.19 points to 1,350.75.

The disappointing report on energy usage also depressed U.S. markets as the Dow Jones industrial average dropped 93.79 points to 10,197.47.

The Nasdaq composite index was down 17.88 points to 2,149.02 and the S&P 500 index fell 11.27 points to 1,087.24 as retailing giant Wal-Mart -- an influential indicator of consumer spending sentiment across North America -- delivered disappointing sales numbers even though its profits were up.

Wal-Mart beat expectations on earnings, reporting a 3.2 per cent increase in third-quarter profit to US$3.24 billion as revenue rose to $99.4 billion from $98.3 billion.

But the company said that sales at stores open at least a year fell 0.4 per cent during the quarter, marking the second consecutive quarter that it saw this important measure fall. Still, Wal-Mart shares rose 27 cents to US$53.24.

Market performance has been tepid for most of this week. But six straight sessions ended Monday had pushed the TSX up almost six per cent, with investors confident U.S. interest rates will stay close to zero for some time and that governments are in no rush to remove stimulus measures.

Some analysts think, however, that while the market remains strong, analysis of past stock market rallies points to this one being due for a pause.

"The rallies in similar bull markets following similar bear markets that precede them lasted anywhere from nine to 10 months -- and we're into the eighth month now," observed Paul Thornton of Investor Boot Camp Online.

"We might have another six to eight weeks on the upside here (and), when the market goes into a correction, it is not going to be pleasant."

In other Canadian earnings news, telecom giant BCE Inc. (TSX:BCE) reported that net income applicable to common shares more than doubled to $558 million in the third quarter, up from $248 million last year. Operating revenue came in at $3.78 billion, up $40 million and BCE shares rose five cents to $27.14.

Canadian Tire Corp. (TSX:CTC.A) shares rose 47 cents to $58.24 as the retailer said that third-quarter revenue fell six per cent to $2.45 billion. Net income fell 21.8 per cent to $85.4 million. The company says its core retail business remained stable but profit was hit by higher loan losses at its financial services business.

Diversified investment company Onex Corp. (TSX:OCX) lost $180 million in the third quarter, reversing a year-earlier profit largely due to impairment charges at its Hawker Beechcraft aviation business. Onex's third-quarter loss amounted to $1.48 per share compared to net earnings of $38 million or 30 cents per share in the third quarter of 2008. Revenues declined 14 per cent to $6.1 billion and its shares were down 32 cents to $23.78.
