OTTAWA, Sept. 4 (Xinhua) -- Canada's ruling Conservative Party will gain victory in an election, with an edge of 10 percentage point support over the Liberal Party, according to a new poll released Thursday.

    The survey, conducted by Environics between Friday and Tuesday for national broadcaster Canadian Broadcasting Corporation (CBC), found that 38 percent of Canadians would vote for the Conservative party if an election were held immediately.

    By comparison, 28 percent would vote for the Liberal party, 19 percent for the New Democratic Party (NDP), 8 percent for the Bloc Quebecois and 7 percent for the Green Party.

    Even when undecided voters were asked to reveal whom they were inclined to vote for, the Conservatives still kept the lead with 33 percent, Liberals 24 percent, NDP 16 percent, Bloc Quebecois 7 percent and Green Party 6 percent.

    The result came after sources said Thursday that Prime Minister Stephen Harper will call an election Sunday, scheduled on Oct. 14.

    The poll also shows that support for the Conservatives has grown since the beginning of the summer. A similar survey conducted in late June and early July showed the Conservatives with 35 percent support of decided voters, while the Liberals had 30 percent, the NDP had 17 percent, the Greens had 10 percent and the Bloc had 8 percent.

    The minority Conservative government went to power in the January 2006 election, gaining 36 percent of the total votes.
