MethodologyReport on the Survey of Special Ballot Voters for the 43rd General Election

The experiences of electors who voted by special ballot were evaluated using an online survey.

To distribute the survey, special ballot voters were sent a bilingual survey postcard that contained a Quick Response code and website address, along with a unique reference code. The postcards were distributed to most special ballot voters (except for incarcerated voters).1 Mail-in voters (national and international) received them in their voter kits along with their ballots, while voters at Elections Canada (EC) offices, campus voters, acute care voters, home visit voters and Canadian Forces voters were given a survey postcard after they had cast their ballot.

To take the survey, voters were required to enter their unique reference code. The survey was in field from September 16, 2019, until November 4, 2019, and 3,512 respondents completed it. It took an average of 5.7 minutes for respondents to complete the survey. This was a non-random sample, and therefore no margins of error are applicable, and it is not generalizable to the general population.

Data were weighted to reflect the population of special ballot voters by age and by voting method. See Appendix A for the profile of survey respondents and Appendix B for the distribution of administrative data compared with weighted survey data.

1 Due to an unforeseen shortage of survey postcards (around 34,000), not all mail-in voters (in and outside Canada) received one. Once the shortage became known, however, between 1,500 and 2,000 postcards were distributed every Wednesday that followed, until the end of the fielding period.
