TORONTO, Sept 8 (Reuters) - The Canadian dollar ended the session weaker against its U.S. counterpart on Thursday as investors sought safety after a speech by Federal Reserve chief Ben Bernanke lacked details on plans to spur economic growth.

“It really is about the general dollar tone and risk assets, and we see equity markets off again today and typically there is a very strong and sustained positive correlation between the Canadian dollar and risk assets,” said Shaun Osborne, chief currency strategist at TD Securities.
The Canadian dollar CAD=D4 ended the North American session at C$0.9880 to the U.S. dollar, or $1.0121, down from Wednesday's North American close of C$0.9855 to the U.S. dollar, or $1.0147.
Osborne said the currency could have a volatile ride in the weeks ahead as it tracks the U.S. equity market through what is a traditionally bad month.
“September generally is not a positive month for risk assets. Historically it is the worst performing month for S&P 500 returns, so chances are we’re going to see a bumpy ride for stocks for the next little while and that means the Canadian dollar will likely slip back,” he said.
U.S. stocks ended the day lower with Dow Jones industrial average .DJI and Standard & Poor's 500 Index .SPX both down more than 1 percent. The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE closed down 0.29 percent as strength in gold-mining stocks helped cushion the fall.
