The Division of Respiratory Medicine (also known as the Division of Respirology, or the Division of Pulmonary Medicine) encompasses all of the major subspecialty interests in the field of respiratory medicine.

In recent years we have expanded our divisional faculty and we now have clinical professors with key clinical and research interests in all aspects of respiratory medicine, including interventional pulmonology, adult cystic fibrosis, tuberculosis, post lung transplant care, exercise physiology, pleural diseases, pulmonary hypertension, respiratory and ventilatory care of chronic neuromuscular diseases, and sleep medicine.

The Division of Respiratory Medicine has achieved continuing and increasing success in research productivity.  Our expertise is in clinical research and clinical and population epidemiology.  Our faculty publish widely in the best medical journals in the world, including NEJM, Lancet and JAMA.

Our Respirology program is fully accredited by the Royal College and attracts large numbers of applicants from across the country each year. Our residents benefit from broad clinical exposure to all aspects of respirology and an extensive educational curriculum provided by very supportive and collegial faculty. We generally accept two to three PGY4 residents per year.

Our catchment area includes Eastern Ontario, Western Quebec, and Nunavut.  We service a catchment area of about 1.3 million people.  We run outpatient clinics every day in a variety of subspecialty areas.  We hold outreach clinics in Nunavut, and in smaller towns in Eastern Ontario.  We also have a 16 bed inpatient Respirology unit at The General Campus of The Ottawa Hospital.


In the Division of Respirology research is focused in the areas of clinical research, and clinical and population epidemiology.  Our research faculty is growing and has been very productive in recent years.  Since 2003 members of our faculty have published first-author research publications in:  The NEJM, Lancet, JAMA, Annals of Internal Medicine, CMAJ, The American Journal of Respiratory and Critical Care Medicine, as well as many other subspecialty journals.   Members of our group hold a large number of peer-reviewed research grants from CIHR, The Ontario Thoracic Society, The Canadian Cystic Fibrosis Foundation, and The Canadian Cancer Society.
