Methodology The results for this wave of research are based on online research conducted from March 7 to March 10, with a representative sample of 1,548 Canadian adults 18 years of age and older from Leger’s LEO panel. The data was statistically weighted according to 2021 Canadian Census figures. ​ A margin of error cannot be associated with a non-probability sample in a panel survey, but for comparison purposes, a probability sample of 1,548 would have a margin of error of +/- 2.49%, 19 times out of 20.
