An election is a torture chamber for politicians, voters and pollsters – and rightly so. 

At Nanos we take very seriously our responsibility as a research firm and the trust Canadians place in our numbers. In addition to the exceptional coverage by our clients — CTV News and the Globe and Mail, and Bloomberg News — the Nanos numbers were cited by virtually all major media outlets in Canada and several international ones such as by The Associated Press, The Wall Street Journal, The Washington Post, the Los Angeles Times, the Guardian Newspaper in the UK and the BBC.

Over the course of the election, the Nanos numbers were also a central part of the dialogue on social media.  For example, our polling was cited in 55.2 million tweets during the campaign.

A review of our tracking in Canada’s 42nd federal election suggests that the Nanos track record of reliability in national and provincial elections continues from strength to strength.  Our approach of using random land- and cell-line samples with live agents, in our opinion, remains the most consistently robust means of measuring opinion.

Here is a comparison of the election results to the Nanos data using the Election Canada data as of 1:20 am ET.

As you can see, this contributes to the Nanos track record which is among the most consistently accurate for national and provincial elections in Canada. 

For this federal election, Nanos accurately called the winner in all regions, the results for every party were well within the margin of error and accurately forecast the Liberal victory.

Methodology

A national random telephone (land + cell) survey using live agents of 1,200 Canadians is conducted by Nanos Research throughout the campaign over a three day period.  Each evening a new group of 400 eligible voters are interviewed. A double sample of 800 interviews, per night, were conducted on Friday, Saturday and Sunday. Today’s daily tracking figures are based on a three-day rolling sample comprised of 2,400 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 2,400 respondents is ±2.0%, 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 2011 Canadian Census administered by Statistics Canada.  Percentages reported may not add up to 100 due to rounding.  The research has been registered with the Marketing Research and Intelligence Association of which Nanos is a member.

Results are based on the three day calling window October 16 to 18, 2015. The research was commissioned by CTV News and The Globe and Mail.
