E-cigarette use by province

See data table below with 95% confidence intervals. Prevalence of ever trying e-cigarettes among students in grades 7-9 varied significantly by province,¹⁹⁰ ranging from 6.9%^a in Ontario to 23.3%^b in Nova Scotia (Figure 13.3).

Past 30-day use of e-cigarettes also varied significantly by province,¹⁹¹ ranging from 2.8%^c in Ontario to 12.9%^d in Nova Scotia.

Between 2014-15 and 2016-17, estimates for ever use of e-cigarettes increased in some provinces, while remaining similar or even decreasing slightly in others (Table 13.1). Estimates for past 30-day use appear to have increased in all provinces, although to varying degrees. Increases in prevalence estimates between survey waves were particularly large in Nova Scotia.
