"The downward momentum had already been established," said Pat McHugh, senior portfolio manager at Manulife Asset Management. "And it's a Friday," he said, noting terrorism threats against New York and Washington ahead of the 10th anniversary of 9/11 attacks prompted investors to sell equities ahead of the weekend.

Adding to the gloom was news that the Canadian economy lost 5,500 jobs in August and that the jobless rate rose to 7.3 percent. The data was far worse than forecast and overshadowed other signs the economy was making a comeback after a bleak second quarter. [ID:nN1E7880PE]
"The Canadian jobs numbers didn't help sentiment," Picardo said. "It underscores the fact that our economy remains quite susceptible, quite vulnerable to global concerns."
