METHODOLOGY

Nanos conducted a national random telephone survey (land- and cellular-line sample using live agents) of 1,200 Canadians throughout the campaign over a three-day period. Each evening a new group of 400 eligible voters are interviewed. The daily tracking figures are based on a three-day rolling sample comprising 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.

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. Percentages reported may not add up to 100 due to rounding.
