TORONTO - Stock markets are selling off sharply as dreadful unemployment numbers deepen pessimism about the economy.

Toronto's S&P/TSX composite index was down 190.17 points to 7,867.65 late in the morning as investors took in grim Canadian and U.S. data.

Statistics Canada reported the economy shed 70,600 jobs last month, the biggest one-month drop since 1982, and the unemployment rate rose to 6.3 per cent.

New York's Dow Jones industrial average surrendered 211.62 points to 8,164.62 after the U.S. Labour Department tallied American job losses at 533,000, far more than the 320,000 economists had expected. The U.S. jobless rate increased two-tenths of a percentage point to 6.7 per cent.

Falling commodity prices and the weak employment report, against a backdrop of political uncertainty, sent the Canadian dollar down to a four-year low of 76.88 cents US. Later in the morning the currency was down 1.18 cents at 77.06 cents, extending the previous day's 1.54-cent slide.

The TSX energy sector fell 5.2 per cent as the January crude contract in New York slid $1.83 to US$41.84 a barrel, down for a sixth session on growing worries about demand in the face of worsening economic conditions.

The U.S. employment report "was much worse than was expected and represents wholesale capitulation -- the threat of a widespread depression is now real and present," declared Peter Morici, a business professor at the University of Maryland.

The base metals sector was slightly lower as cuts in resource-industry capital spending continued. Thompson Creek Metals Co. (TSX:TCM) is slashing its 2009 capital budget to $69 million from $300 million, as it puts off expansion of the Endako molybdenum mine in B.C. Its shares were unchanged at $3.45.
