The overall prevalence of e-cigarettes in Canada increased between 2017 and 2019 for all outcomes: e-cigarettes in the past 30 days (2017 = 8.4%, 2018 = 12.1%, 2019 = 17.8%; P < .001), in the past week (2017 = 5.1%, 2018 = 7.5%, 2019 = 12.3%; P < .001), and on ≥20 days in the past month (2017 = 1.8%, 2018 = 2.4%, 2019 = 5.7%; P < .001). Respondents who reported noticing marketing often or very often were more likely to report e-cigarettes in the past 30 days (AOR = 1.41, 95% CI = 1.23–1.62, P < .001), in the past week (AOR = 1.44, 95% CI = 1.22–1.70, P < .001), and on ≥20 days in the past month (AOR = 1.42, 95% CI = 1.11–1.81, P = .005).

As indicated in Fig 3, the prevalence of e-cigarettes in the past 30 days increased from 2017 to 2019 for all provinces (high restrictions: AOR = 2.09, 95% CI = 1.52–2.87, P < .001; moderate-high: AOR = 2.25, 95% CI = 1.45–3.50, P < .001; moderate: AOR = 2.70, 95% CI = 1.24–5.86, P = .01; low-moderate: AOR = 2.84, 95% CI = 2.26–3.57, P < .001; low: AOR = 2.28, 95% CI = 1.59–3.25, P < .001). Similarly, the prevalence of e-cigarettes in the past week increased from 2017 to 2019 for all provinces (high restrictions: AOR = 1.98, 95% CI = 1.35–2.91, P < .001; moderate-high: AOR = 3.67, 95% CI = 2.01–6.72, P < .001; moderate: AOR = 3.09, 95% CI = 1.19–8.01, P = .02; low-moderate: AOR = 3.18, 95% CI = 2.37–4.27, P < .001; low: AOR = 2.41, 95% CI = 1.59–3.64, P < .001). The prevalence of e-cigarettes on ≥20 days in the past month increased from 2017 to 2019 in all provinces except those with moderate restrictions (high restrictions: AOR = 2.46, 95% CI = 1.41–4.28, P = .001; moderate-high: AOR = 5.00, 95% CI = 1.76–14.2, P = .003; moderate: AOR = 2.38, 95% CI = 0.60–9.45, P = .22; low-moderate: AOR = 4.01, 95% CI = 2.41–6.67, P < .001; low: AOR = 3.59, 95% CI = 1.74–7.41, P < .001).

Compared with provinces with the strongest marketing restrictions, across all waves, the prevalence of e-cigarettes in the past 30 days was higher in provinces with moderate-high (AOR = 1.30, 95% CI = 1.06–1.59, P = .01) and low restrictions (AOR = 1.50, 95% CI = 1.25–1.80, P < .001), whereas the prevalence of e-cigarettes in the past week was also higher among provinces with moderate-high restrictions (AOR = 1.27, 95% CI = 1.00–1.62, P = .05) and low restrictions (AOR = 1.65, 95% CI = 1.33–2.05, P < .001). The interaction between year and policy was not significant for past 30-day (P = .14), past-week (P = .12), or e-cigarettes on ≥20 days in the past month (P = .61).
