TORONTO, Jan 21 (Reuters) - The Toronto Stock Exchange’s main index plunged more than 600 points on Monday, its fifth day of heavy losses, as worries over a possible recession in the United States yanked it to its lowest close in more than a year.
The S&P/TSX composite index .GSPTSE closed down 604.98 points, or 4.75 percent, at 12,132.14 with all of its 10 sectors in negative territory. It was the biggest one-day net drop since Oct. 25, 2000, when the index closed down 840.26 points.
Since last Tuesday, the S&P/TSX composite has lost more than 1,500 points, or 11.4 percent, wiping out all of 2007’s gains. Monday was the lowest closing level since early November of 2006.
Resource issues led the freefall on Monday, with the energy and materials sectors each giving up 5.7 percent. The groups have been stung by worries that demand for resources could be dampened by a slowdown.
Commodity prices weighed on the sectors, as oil and gold prices fell, following the direction of global stocks.
Suncor Energy SU.TO tumbled C$4.52, or 4.9 percent, to C$88.32, while Potash Corp of Saskatchewan POT.TO was down C$5.93, or 4.7 percent, at C$119.57.

“I think there’s some people that have just thrown in the towels, as we can see, and took their signal from what happened overseas,” said Brian Pow, vice president, research and equity analyst at Acumen Capital Partners, in Calgary.
Quebecor World Inc was down 17 Canadian cents, or 50.8 percent, at 17 Canadian cents after saying it would file for creditor protection after conditions for a C$400 million ($388 million) rescue financing were not met.
