This survey was conducted by Leger Marketing through telephone interviews among a representative sample of 2,092 English- or French-speaking Canadians, 18 years of age or older.
The interviews were conducted from our Montreal call centre between May 28 and May 30, 2004. Up to ten call-backs were made in the case of non-response.
Using data from Statistics Canada, the results were weighted according to geographic location, gender and language spoken at home to ensure a sample representative of the entire Canadian adult population. In the end, the maximum margin of error obtained for a sample of 2,092 respondents is + 2.14%, 19 times out of 20.
