TORONTO, May 2 (Reuters) - The Canadian dollar softened against the U.S. currency on Monday, pulled down by weaker commodity prices after U.S. forces killed al Qaeda leader Osama bin Laden and uncertainty over the day's federal election.

"The election is certainly on global participants' minds ... markets are somewhat nervous," said Camilla Sutton, chief currency strategist at Scotia Capital.
"Even though tonight we get the results it doesn't necessarily end all the uncertainty as to what happens. So there could still be more to come in the weeks and even months ahead."
The right-of-center Conservatives, who have governed Canada since early 2006, started the campaign with a healthy lead. But that lead dwindled in the face of a campaign by the left-leaning New Democrats, a pro-labor party that has never held power in Canada.

The currency CAD=D4 ended the North American session at C$0.9508 to the U.S. dollar, or $1.0517, down from Friday's close at C$0.9464 to the U.S. dollar, or $1.0566.
Analysts say in the short-term, the 3-1/2 year high hit on Friday at C$0.9440 to the U.S. dollar, or $1.0593, will be closely watched.
"If we did see something like a Conservative majority, we could play a little bit of a catch-up here," added Sutton.
She placed near-term support for the Canadian dollar around C$0.9550 and noted that liquidity was lighter than usual with holidays in the UK and much of Asia.
John Curran, senior vice president at CanadianForex, said the Canadian dollar should bounce back despite some underperformance related to the election.
"I don't think it's going to matter who gets in. Eventually the market will come to the terms (with the fact that) Canada is a stable country. Things will be fine and the Canadian dollar will strengthen," Curran said.
Canadian bond prices were little changed across the curve, tracking U.S. Treasuries, as traders concluded the global war on terror and related safety bids for bonds will continue even after bin Laden's death.
The two-year bond CA2YT=RR was unchanged to yield 1.704 percent, while the 10-year bond CA10YT=RR rose 7 Canadian cents to yield 3.204 percent. (Editing by Jeffrey Hodgson)
