TORONTO, Aug 17 (Reuters) - Toronto's main stock market index dove on Monday morning as commodity-linked stocks sank with oil and metals prices on worries over the pace of economic recovery.
Energy, financial, and gold-mining companies led the broad decline as commodity prices slid on worries about the health of of the U.S. consumer that were underlined by below-par results from U.S. home improvement retailer, Lowe's Cos Inc (LOW.N).
Also disconcerting the market was data that showed Japan's economy emerged from its longest recession in at least 60 years in the second quarter, but that the recovery may be shaky. [ID:nSP435211]
Suncor Energy (SU.TO) sank 4.6 percent to C$34.19, while Canadian Natural Resources (CNQ.TO) tumbled 3.2 percent to C$62.16. Gold miner Barrick Gold (ABX.TO) fell 3.9 percent to C$35.95, while Goldcorp (G.TO) dropped 3.8 percent to C$37.52.
Canada's biggest bank, Royal Bank of Canada (RY.TO), fell 2.5 percent to C$50.10.
The stock market tumble reflects persistent concerns about the "global growth story," said Francis Campeau, broker at MF Global Canada, in Montreal.
"That's why the commodity sectors are getting hit," he said.
Oil prices CLc1 fell below $66 a barrel and metals prices dropped sharply on Monday. [ID:nSYD485910]
