The most influential falls came from Canadian Pacific Railway Ltd (>> Canadian Pacific Railway Limited), which fell 4.1 percent to C$208.80, and Toronto-Dominion Bank (>> Toronto-Dominion Bank), which declined 1.1 percent to C$55.37 despite posting a surprisingly strong quarterly profit.

"Today is another example of investor confusion about which way to turn," said Julie Brough, vice president at Morgan Meighen & Associates, citing myriad worries from a possible Greek default to Middle East violence to Fed rate hikes.

"Nobody's feeling exuberant right now. It's a cautious attitude that's taken hold," she said.

The Toronto Stock Exchange's S&P/TSX composite index <.GSPTSE> ended down 3.47 points, or 0.02 percent, at 15,107.00.

Brough said Canadian Pacific's fall was likely a direct hit from the loss of traffic it will suffer as Teck Resources temporarily shuts its six Canadian coal mines.

The overall industrials group retreated 1.5 percent, while the financials group slipped 0.1 percent.

Among the three banks that reported on Thursday, Canadian Imperial Bank of Commerce (>> Canadian Imperial Bank of Commerce) also raised its dividend, joining two of Canada's Big Six banks that hiked their payouts earlier this week. CIBC (>> Canadian Imperial Bank of Commerce) gained 0.6 percent to C$95.63.

While increased dividends will help banks win favor, the focus now is how they deal with higher interest rates, said John Ing, president of Maison Placements Canada.

"A lot of portfolio managers have been backing away from the banks," he said. "For a long time it was a profitable trade but the outlook is a lot more difficult."

Among the Big Six, only Bank of Nova Scotia (>> Bank of Nova Scotia) is left to report quarterly earnings, on Friday.

With oil and gas stocks, another major component of the index, also lacking clear buy signals, Ing said he would not be surprised to see the benchmark index continue to fall in coming weeks.

Oil prices steadied on Thursday after a two-day slide as investors awaited data from the U.S. Energy Information Administration to see how U.S. oil production was responding to a recent surge in prices. [O/R]

Among oil shares, Suncor Energy Inc (>> Suncor Energy Inc.) closed up 0.5 percent at C$36.50, while Canadian Natural Resources (>> Canadian Natural Resources Limited) was up 0.8 percent at C$38.24.
