What is the percentage of Canadians that have emphysema?

As of my last knowledge update in October 2023, approximately 2% to 4% of Canadians are estimated to have emphysema, a condition often associated with chronic obstructive pulmonary disease (COPD). The prevalence can vary based on age, smoking habits, and environmental factors. For the most accurate and current statistics, it's advisable to consult health organizations or recent studies.
