Historical trends in smoking prevalence 

Over the past five decades, there has been a remarkable reduction in smoking in Canada: approximately half of Canadians smoked in 1965, compared to just 15.1% in 2017 (Figure 1.1). Overall smoking prevalence has decreased fairly steadily over this time period. Historically large sex differences in smoking prevalence have narrowed over time to within a few percentage points, although smoking has remained more prevalent among males.
