Toronto stocks dropped sharply late in the session on Monday, ending up with a 100-point loss as interest rate worries and profit doubts knocked the key index to its lowest close since March 1.

The TSE 300 finished down 104.83 points, or 1.33%, at 7,751.30, with the decline led by market heavyweights BCE Inc and Bombardier Inc.

Communications conglomerate BCE fell $1.72 to $29.73, continued to feel the effects of an earnings warning issued last Thursday.

Aircraft-maker Bombardier slipped 40 cents to $13.95, after the company’s Montreal-based aerospace workers voted 98.2% in favor of a strike.

Market weakness was broad, as all but one TSE subgroup finished the session lower, as gold stocks rose 3.28%.

The S&P/CDNX Composite Index closed down 4.35 at 1162.63. Trading was heavy today with a volume of 37.2 million shares changing hands, with 180 advances, 274 declines and 624 issues unchanged.

Stocks skidded in light volume on Monday in New York, knocking the Dow to its fourth straight losing session as the threat of struggling corporate profits and rising interest rates blurred the brightening economic picture.

Growing hopes that the U.S. economy is emerging from its year-long slump helped bolster stocks earlier this month, but investors now are hoping that strength reaches corporate bottom lines.

The market finished near its session lows as selling accelerated in the final hour of trade. The Nasdaq Composite Index fell 38.91 points, or 2.10%, to 1,812.48. The S&P 500 Index dropped 16.82 points, or 1.46%, to 1,131.88.

The Dow Jones industrial average sank 146 points, or 1.40%, to 10,281.67, suffering its longest losing streak in six weeks.
