TORONTO, Nov 1 (Reuters) - Toronto's main stock index ended slightly lower on Monday with investors cautious ahead of Tuesday's U.S. midterm elections and the start of the U.S. Federal Reserve's policy meeting the same day.

Suncor Energy (SU.TO) was up 1.1 percent at C$33.03, while Canadian Natural Resources (CNQ.TO) gained 0.11 percent to C$37.17. The broader energy group rose 0.4 percent.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE finished the day down 11.43 points, or 0.09 percent, at 12,664.81. Six of the index's 10 main groups were lower, pulling the index from the day's peak of 12,759.06, its highest level since Sept. 22, 2008.

If they do, North American equities could see a bit of a bounce, said Francis Campeau, broker at MF Global Canada, in Montreal.
"Republicans are considered more market friendly," said Campeau. "It's always a question to know what's priced in the market already."
Campeau added most market players were largely "waiting on the side" ahead of the election, as well as Wednesday's conclusion of the Fed's two-day policy meeting.
Most leading economists expect the Fed to buy between $80 billion and $100 billion worth of assets per month under a new quantitative easing program -- widely referred to as "QE2" -- to bolster the struggling economy, according to a Reuters poll. [FED]
Bob Gorman, chief portfolio strategist at TD Waterhouse, said all eyes are on the Fed.
"I think the much bigger story is the one that follows on Wednesday when the Fed comes out with its pronouncements about exactly it intends to do with respect to QE2," he said.
"This may well be situation where having bought on the anticipation of this you see some selling on the news. We don't know."
