At 7:38 a.m. (1138 GMT), the Canadian dollar was at C$1.0770 to the U.S. dollar, or 92.85 U.S. cents, down from C$1.0697 to the U.S. dollar, or 93.48 U.S. cents at Friday's close.
"We've had a fairly significant correction in commodities and equities," said David Bradley, director of foreign exchange trading, Scotia Capital. "That's basically what's led the Canadian dollar weaker."
The price of oil CLc1, a key Canadian export, fell below $71 a barrel, while gold fell below $1,000 an ounce and base metals were largely weaker. [O/R] [GOL/] [MET/L]
