The major federal parties are gripped in a three-way tie, according to the latest polling by Nanos Research for CTV and The Globe and Mail.

The latest numbers for the three leading parties:

Conservatives: 31.7 per cent

NDP: 30.8 per cent

Liberals: 30.5 per cent

Voters were asked: "If a federal election were held today, could you please rank your top two current local voting preferences?"

The daily tracking figures are based on a three-day rolling sample comprising 1,200 interviews. Each evening, 400 eligible voters are interviewed. The tracking is updated each day by adding information from a new day and dropping the oldest day.

The margin of error for a survey of 1,089 decided voters is ±3.0 percentage points, 19 times out of 20.

Poll Methodology:

A national dual-frame (land and cell) random telephone survey is conducted nightly by Nanos Research throughout the campaign using live agents. Each evening a new group of 400 eligible voters are interviewed. The daily tracking figures are based on a three-day rolling sample comprised of 1,200 interviews. To update the tracking a new day of interviewing is added and the oldest day dropped. The margin of error for a survey of 1,200 respondents is ±2.8 percentage points, 19 times out of 20.
