The majority (63.1%) of Canadians who have ever been smokers have now quit. Figure 6.1 (below) shows the percentage of respondents who have ever smoked, including both current and former smokers, as well as quitter percentage (the percentage of ever smokers who were former smokers at the time of survey) over time. Quitter percentage slowly increased between 1999 and 2005, and then remained around 60% for a number of years, before appearing to increase again in the most recent years.
