(Reuters) - Canada's main stock index extended losses on Monday from its sharpest decline this year in the previous session, as investors fled riskier assets on concerns over a softening global economy.

The energy sector posted the steepest drop of 1.2 percent as U.S. crude prices were down 0.5 percent a barrel, while Brent crude lost 0.2 percent. [O/R]
However, gains in mining stocks, which got a lift from investors flocking to the safe-haven bullion, countered heavy losses in the energy sector.
The materials sector added 0.6 percent as spot gold gained 0.5 percent to $1,319.61 an ounce. [GOL/] [MET/L]
