ABOUT THE SURVEY
In an independent opinion poll, commissioned by Reader's Digest, Ipsos Canada conducted an online survey of over 4,000 Canadian adults from Sept 9-16, 2016. Quota sampling was used and the sample was stratified by language (English n = 3,053 and French n = 956.) Respondents were asked for their most trusted brand within each category, in an open-ended question format. Results were weighted to census data to be representative of the population. Using a credibility interval, the overall results are considered accurate to within +/-1.8 percentage points, 19 times out of 20, of what the results would be had the entire population of adults been polled.
