Over 2 million Canadians have asthma, and despite the availability of effective treatment, approximately 9 in 10 people with asthma do not have it under control.

Although asthma can develop at any age, it is more common among children. Asthma is one of the leading reasons for missing school and work: about a third of asthma sufferers miss school, work, or other social activities due to their asthma. About 40% of asthma sufferers don't exercise at all due to their asthma.

Proper control of asthma can greatly reduce its effects on your daily life. The more you know about your asthma, the more you know about what you can do to keep it under control. Learn what triggers your asthma and how to properly use your inhaler(s), and use your medications as prescribed by your doctor – these are essential ingredients in achieving asthma control.
