Toronto (Bloomberg) — Canadian stocks fell for the first time in three days, paced by commodity producers including Alcan and Talisman Energy, as copper prices declined the most in a month and a week-long rally in oil prices stalled.Energy and materials shares had led the market higher in the past week as oil and metals rose and investors speculated there may be more take-over offers, following yesterday’s $4 billion bid for LionOre Mining International from Xstrata.

Financial shares such as Manulife Financial also dropped today as declines in US home prices and consumer confidence stoked concern spending may slow in Canada’s biggest export market.

“The market’s taking a bit of a breather. We’ve had a pretty good run in the past few days,” said Paul Hand, managing director, equity trading, at RBC Capital Markets in Toronto. “Yesterday we were lucky to have the LionOre bid.

The housing figures have people worried about the consumer.”

The Standard & Poor’s/TSX Composite Index fell 84.12, or 0.6 percent, to 13,218.76 in Toronto. All 10 industry groups slid.

A gauge of materials stocks lost 1.2 percent and was the biggest drag on the benchmark, while energy shares declined 0.3 percent as a group.

Alcan, the second-biggest maker of aluminium, declined 71 cents to C$61.34. Teck Cominco, the second-largest zinc producer, fell 82 cents to C$82.41.
