These data were collected as part of an international educational project. Schools participated voluntarily and were not part of a representative sample of the school population.
The survey was answered by 7,683 students across Canada during the 2003/2004 school year using two questionnaires, one for elementary and the other for secondary students. The elementary category includes grades 4 to 8 (secondary 2 in Quebec) and the secondary category includes grades 9 to 12 (secondary 3 to 5 in Quebec).
The following tables show results for Canada for selected questions that appeared in both questionnaires. Note that percentages may not add to 100 due to rounding.
