TORONTO -- The Toronto stock market was pulled down by lower commodities prices on Monday as concerns about the European economy returned to the forefront.

The S&P/TSX composite index moved back 70.06 points to 12,313.54. The TSX Venture Exchange fell 12.26 points to 1,333.46.

The Canadian dollar was 0.25 of a cent lower at 102.17 cents US. And both crude oil and gold prices lost ground, as questions about demand impacted prices.

November crude on the New York Mercantile Exchange moved down 96 cents to US$91.93 a barrel.

The December bullion contract decreased $13.40 to US$1,764.60 an ounce. December copper was off five cents to US$3.74 a pound.

The TSX gold sector was down with Barrick Gold Corp. (TSX:ABX) dropping $1.17 to $40.45. Energy stocks were off 1.2 per cent, and Talisman Energy (TSX:TLM) fell 20 cents to $13.42.

With little major economic data on the calendar this week, investors will likely return focus to Europe and whether Spain will tap a new European aid program. Also in focus will be the direction of the Chinese economy after data last week suggested further weakness.

In Germany, a business confidence index released Monday showed that the biggest European economy saw declines for the fifth straight month, surprising many economists.

The shine has been wearing off what has been an optimistic month for stock markets, characterized by an enthusiastic climb that defined much of the first half of September. The latest indicators, however, suggest the global economy is still slowing down and recovery will take time.

"I think we're seeing some of the risk factors that are prevailing in this market starting to emerge," said Craig Fehr, Canadian markets specialist at Edward Jones in St. Louis.

"The economic data is not coming in consistent to the upside or the downside right now. So it's a daily, weekly and monthly characterization that investors are having to make going forward."

Europe's debt crisis will remain a point of focus for investors. Spain is due to unveil a new series of cost-cutting measures and structural reforms that could pave the way for a demand for financial aid from its fellow eurozone countries.

Spanish stock and bond markets have been volatile in recent days as hopes that Madrid will apply for the aid alternated with concern that it was delaying the move.

On Friday, the country will also release a final estimate of the financing needs of its weakest banks. The figures will help the government determine how much of an existing C100 billion (US$130 billion) eurozone rescue loan -- earmarked for the banks -- it should use.

In corporate developments, Canaccord Financial Inc. (TSX:CF) is closing 16 branches of its wealth management firms across the country and reducing the number of advisors at the remaining Canadian locations, which will be concentrated in major cities.

Valeant Pharmaceuticals International, Inc. (TSX:VRX) says it has paid $112.5 million to acquire the rights to Visudyne, a treatment for a common form of age-related blindness.

QLT shares were up 56 cents to $7.97.

Hanfeng Evergreen Inc. (TSX:HF), a fertilizer company focused on China and other Pacific Rim countries, says it has taken a $10-million writedown to reflect the reduced value of its publicly-traded stock. The company, which has its Canadian head office in Toronto, said the writedown and other charges resulted in a loss of $2.5 million or four cents per share in its fiscal fourth quarter. Hanfeng shares were ahead three cents to $1.77.
