Recent temporal trends in the population prevalence of chronic pain in Canada on a national and provincial level are unknown. Five cycles of the Canadian Community Health Survey (2000/2001, 2007/2008, 2009/2010, 2011/2012, and 2013/2014) were used to derive population-based estimates of the self-reported prevalence of chronic pain. Sensitivity analyses examined chronic pain prevalence among those reporting no other chronic health conditions. The prevalence of chronic pain among the general Canadian population increased by almost 4.0% (to 21.0%) in 2011/2012, after being in the range of 15.7 to 17.2% from 2000 to 2009/2010. The sudden increase in prevalence was observed 1) across all provinces in Canada, 2) in all age categories, and 3) among Canadians with no other chronic health conditions. Increasing chronic pain prevalence in Canada, most significantly occurring between 2010 and 2012, and including among healthy and young individuals, emphasizes the need for targeted research and resources to help alleviate chronic pain. PERSPECTIVE: This study uncovers a significant increase in chronic pain prevalence in Canada between 2009/2010 and 2011/2012, driven by younger Canadians that are free of the most common chronic health conditions. This discovery emphasizes the importance of further directed research and resources to help mitigate the trend of increasing chronic pain.
