Canada's main stock market in Toronto opened another week on a down note with a triple-digit loss that brought the index down to 30-month low levels.
The Toronto Stock Exchange's benchmark Standard & Poor's/TSX Composite Index lost 131.29 points, or 1.09 percent on Monday, to close at 11,942.17 points, Xinhua news agency reported.
All of the index's eight main sectors ended negative.
The last time the TSX closed below 12,000 points was in June 2013. The index is now down almost 23 percent from its all-time high close of 15,657.63 set on Sept. 3, 2014.
West Texas Intermediate crude, the main North American contract, fell 48 cents to $28.94 a barrel on Monday at mid-afternoon.
Brent was trading even lower at $28.80 a barrel. It is unusual for the main international contract to fall below WTI in price.
The Canadian dollar was traded lower at $0.6870, compared with Friday's closing rate of $0.6882.
