Historical trends in smoking prevalence 

Over the past five decades, there has been a remarkable reduction in smoking in Canada: approximately half Canadians smoked in 1965, compared to just 13% in 2015—the lowest recorded smoking rate (Figure 1.1). Overall smoking prevalence has decreased fairly steadily over this time period, although this decline appears to have slowed during the 2000s. 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.
