On Sept. 20, Canadians will choose, in the middle of a pandemic, between federal parties who hope to tilt the balance of the minority Parliament. Together with CTV and Nanos Research, The Globe and Mail is doing daily surveys to track which party and leader Canadians prefer. Check back here each morning throughout the campaign for the latest results, and learn more below about the survey methodology.

       SURVEY METHODOLOGY A national random telephone survey (land- and cell-line sample using live agents) of 1,200 Canadians is conducted by Nanos Research throughout the campaign over three-day periods. 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 plus or minus 2.8 percentage points, 19 times out of 20. The respondent sample is stratified geographically and by gender. The data may be weighted by age according to data from the 2016 Canadian Census administered by Statistics Canada.

       Nanos also compiles a weekly “Party Power Index” that measures federal party brands based on four of the poll questions. Learn more about how the index works here.

For those parties you would consider voting for federally, could you please rank your top two current local preferences?
