The Liberals have pulled ahead of the Progressive Conservatives as the second week of the Ontario election campaign gets underway, according to a new poll.

The Nanos Research poll, conducted for CTV, The Globe and Mail and CP24, asked respondents which of the provincial parties they consider to be their top two preferences.

Among decided voters, the Liberals received 38.1 per cent support, the Progressive Conservatives 34.7 per cent and the NDP 24.3 per cent. The Green Party received 2.7 per cent support.

The results indicate the Liberals are on the move, and their lead is within the survey's margin of error.

In an earlier poll conducted on Sept. 1, the Liberals had the support of 31.9 per cent of decided voters, the Tories had 35.4 per cent support, while the NDP had 22.8 per cent. The Greens had 4.1 per cent support.

The latest data indicates the Tories continue on a downward slide. In a similar poll conducted in August, the Tories had 42.1 per cent support. That dropped to 35.4 per cent in the Sept. 1 poll.

The Liberals, on the other hand, have overtaken their numbers from the August poll, which put them at 37.6 per cent support.

Poll methodology: Nanos Research conducted the random telephone survey of 507 Ontarians aged 18 and older between September 10 and 11. The margin of error for the 415 decided voters is plus or minus 4.9 percentage points, 19 times out of 20.
