The NDP and the Greens have inched closer to the Liberals and the Conservatives, who may have slipped further away from majority-government territory, a new poll of voter intentions suggests.
The four-day Canadian Press/Harris-Decima rolling survey, done in partnership with the CBC, gives the Tories 36 per cent of national support, down two percentage points from the previous day's figure.
The Liberals follow with 27 per cent support, down a single point from the previous day, the survey result suggests.
The poll puts the NDP at 16 per cent and the Green party at 11, both up a point, while the Bloc remained at eight per cent support.
The CBC's David Taylor, who is monitoring the polls, said the "gentle trend downwards" for the Conservatives is bound to get attention inside the party, but the campaigns often rely more on their own surveys.
"If they're looking at their own polls and they see something like this, of course what they'll want to do is drill into the 'where'," Taylor said.
He said other polls suggest the Liberals are bouncing back in Ontario, while the battle in Quebec, mainly between the Bloc and the Conservatives, appears to be intensifying.
The Harris-Decima poll also asked respondents to indicate their positive and negative feelings for the party leaders, with Bloc Québécois Leader Gilles Duceppe receiving the highest level of approval for his leadership at 53 per cent.
NDP Leader Jack Layton also placed high on the survey with a 52 per cent approval rating, followed by Conservative Leader Stephen Harper at 47 per cent.
Green Leader Elizabeth May received an approval rating of 41 per cent, while Liberal Leader Stéphane Dion improved slightly with a 35 per cent positive rating, according to the survey.
The poll surveys 300 people a night in a rolling national sampling and the figures are based on interviews with 1,366 people between Sept. 13 and Sept. 16, with a margin of error of 2.6 percentage points, 19 times in 20.
