TORONTO, May 5 (Reuters) - Toronto's main stock index closed lower for a fourth day on Thursday as resource issues took a heavy hit from a major selloff in the commodities market that thrashed high-flying oil and metal prices.
Energy issues slumped 2.68 percent while the materials group, home to mining firms, skidded 2.54 percent. The two groups, which make up roughly 50 percent of the TSX index, dominated the lead decliners.
Suncor Energy SU.TO was by far the biggest drag on the index, sliding 5.26 percent to C$39.60. Goldcorp G.TO fell 3.36 percent to C$47.13, while Canadian Natural Resources CNQ.TO gave back 2.6 percent to C$41.24.
Barrick Gold ABX.TO was down 1.58 percent at C$45.33 while Teck Resources TCKb.TO retreated 3.71 percent to C$47.78.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE closed down 155.94 points, or 1.15 percent at C$13,455.38. Six of the index's 10 main groups were lower.
The index has fallen roughly 3.5 percent since Friday's close and hit its lowest level in seven weeks.
The resource-heavy index took a heavy hit from oil prices, which settled down 9 percent in a record retreat that drove U.S. crude back under $100 a barrel.
Precious metal prices also took a severe hit, with silver plunging to its biggest one-day loss since 1980 and gold falling more than 3 percent. Copper prices also sank more than 3 percent to their lowest level since December.

"Clearly, that's having an effect," said Irwin Michael, portfolio manager at ABC Funds. "Commodities are clearly coming in. There's been a lot of speculation in that area ... At some point, it's going to burn itself out."
