TORONTO, April 28 (Reuters) - Toronto's main stock index ended little changed on Thursday as gold miners and some other mining issues fell and oil and gas shares rose, while corporate results were mixed.
Stronger-than-expected earnings pushed papermaker Domtar Corp UFS.TO,up 1.9 percent to C$87.89, and pharmacy chain Jean Coutu Group PJCa.TO up 1.34 percent to C$10.59.
But news and information provider Thomson Reuters TRI.TO fell 2.61 percent to C$38.11 after it reported adjusted earnings that missed estimates. It said it plans to sell two businesses to fund further investment. [ID:nN26263605]
Imperial Oil IMO.TO cut early losses after reporting a lower-than-expected profit, but still ended the session 0.72 percent lower at C$49.91. [ID:nN27295358]
"We've got some minor variances from expectations that seem to be weighing on the markets a little bit today but there's no big news item that's really got people running one way or another," said Michael Sprung, president at Sprung & Co Investment Counsel.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE ended up 1.83 points at 13,894.40. Six of the index's 10 main groups advanced, with the heavily weighted energy group rising 0.42 percent. The materials group led on the downside, falling 0.76 percent.
Potash Corp POT.TO dragged on the materials group, falling 2.75 percent to C$52.69, after it reported higher quarterly profit but disappointed some investors who had expected more. [ID:nN28203376]
Analysts also said there was also some caution in the market resulting from a surge in the polls by the left-leaning New Democratic Party ahead of Canada's May 2 general election.
The NDP, now second in the polls behind the Conservatives, is proposing significantly higher corporate taxes, and the possibility of the party coming to power has ruffled some market feathers. [ID:nN27126329]
