Creating a world in which no one struggles to breathe

We all need to breathe. It is essential to human existence and of vital importance to each and every one of us. But we rarely think about the 22,000 daily breaths we take – until we have trouble taking them.

The Lung Association is a not-for-profit organization dedicated to helping all Canadians breathe. Our community of donors, patients, researchers, volunteers and professional staff work to ensure Canadians have the healthy lungs, bodies and clean air necessary to breathe. A healthy breath fuels the body and mind. It’s something we should not take for granted.

Our Roots

The Canadian Lung Association was founded in 1900, under the name The Canadian Association for the Prevention of Consumption and Other Forms of Tuberculosis. As one of Canada’s first voluntary health organizations, its aim was to provide facilities for the care of TB patients.

The double-barred cross is one of many crosses famous in history. Godfrey of Bouillon, Duke of Lorraine, was the first Christian ruler of Jerusalem. During the crusades, his banners bearing the double-barred cross signified courage and success to crusaders.

In 1902, tuberculosis workers from many countries met in Berlin to discuss how TB could be wiped out. At that time, tuberculosis was the leading cause of death, outranking all other diseases, famine and war.

As the fight was to be universal, a universal emblem for the movement was needed. Dr. Gilbert Sersiron of Paris suggested that as it was a crusade, the emblem of a successful crusader was appropriate. His recommendation of the Cross of Lorraine was adopted, and the double-barred cross became the worldwide sign of the fight against TB.

The double-barred cross continues to be used as an emblem by the International Union Against Tuberculosis and Lung Disease with members in 152 countries around the world, and by Lung Associations throughout North America.

While we were originally founded to provide care for tuberculous patients, over the years we’ve evolved to meet the changing needs of Ontarians, expanding our focus to asthma, chronic obstructive pulmonary disease, lung cancer and other forms of lung disease. Ontario Lung Association is a registered charity operating as The Lung Association – Ontario.

Today, The Lung Association continues to evolve to build a better breathing future for all of us.

We help Canadians breathe by:

We promote healthy breathing by fighting for policies that protect our air and educate Canadians about what they can do to promote their own lung health.

We support and advocate for those living with conditions that affect the lungs and the ability to breathe, and fight to challenge the stigma and ignorance that can be associated with lung disease.

Through education and research, we work to turn knowledge into action and find cures to diseases that will deliver a future of better breathing for all.

Accountability and Financials

We value the investment our donors and supporters make with us. We work hard to ensure that the funds we receive directly benefit our frontline programs and services and critical research initiatives.
