^a21 school boards included; 8 school boards in Alberta, 13 school boards in Ontario

^b43 secondary schools included; 6 secondary schools in Alberta, 37 secondary schools in Ontario

^cUrbanicity was determined based on school postal codes and Statistics Canada classifications of “rural” area and “small,” “medium,” and “large urban” population centres. “Rural” and “small” population-centre categories were combined due to the low frequency of rural schools

^dSchool-level prevalence of current smoking was based on the proportion of all students who reported smoking cigarettes in the last 30 days and 2014/2015 Canadian Student Tobacco, Alcohol and Drugs Survey estimates of past 30-day smoking for Ontario students. Schools were categorized as “low” if the school-level prevalence of smoking was < 5.6% and “high” if the school-level prevalence of smoking was ≥ 5.6%
