About Dr. Farquhar

Dr. Donald Farquhar is a respirologist - specialist physician in lung conditions - who has been in practice for over 35 years. He grew up in London, Ontario, and obtained his medical degree from Queen’s University in Kingston, Ontario. He completed his residency education and specialty certifications in internal medicine and respirology at Western University’s teaching hospitals, and later earned a master’s degree in Health Policy and Management from the Harvard School of Public Health, with concentration in measurement and improvement of medical care quality.
In his leisure time, Dr. Farquhar enjoys reading, learning to play guitar and piano, spending time with family and friends, and attending all forms of theatre, cinema, and live music. To stay fit, he likes to walk, cycle, run, and work out on an elliptical trainer. He managed to qualify for the Boston Marathon in 2019, and has completed four other marathons in Toronto, Ottawa, and Oregon.
About Our Practice
For the first 30 years of his professional career, Dr. Farquhar practised respirology and internal medicine in a traditional teaching hospital setting, working with teams of residents, medical students and allied health professionals in the care of acutely ill patients on inpatient wards, and ambulatory patients in hospital outpatient clinics.
The significant challenges of the early phase of the COVID pandemic prompted Dr. Farquhar to consider how he might adapt his outpatient practice to better serve the often complex needs, vulnerabilities, anxieties, and mobility challenges of his patients with chronic lung disease.
When he stepped down in 2022 from his roles at Western University’s medical school and teaching hospitals, Dr. Farquhar adopted a multi-site community-based practice that is best described as a ‘distributed care delivery’ model. He sees patients in a variety of settings, which he selects according to patients’ needs, abilities, resources, and home address.
Our practice includes the following sites and modes of care:
Old North Wellness Centre (ONWC)

This is an office practice in central London, which also serves as our practice’s business and mailing address, 775 Waterloo St., Unit 5. The ONWC is accessible by London Transit bus routes and is ideal for patients who live in central and east London. Dr. Farquhar sees patients in this location on Wednesdays.
North London Medical Centre (NLMC)

This is a modern, elevator-accessible, multi-physician clinic and diagnostic testing centre, where Dr. Farquhar sees patients on Thursdays and one Monday per month, in space that he shares with the London Cardiac Institute (LCI). The NLMC is located at 1055 Fanshawe Rd., near Hyde Park Rd., in the most northwestern corner of London.
The NLMC site is suited to those who live in the rapidly growing north and west ends of London, and in the immediately surrounding communities of Ilderton, Komoka and Huron County. Because Fanshawe Rd. is also Ontario Highway 22, the NLMC is accessible to patients who live in Sarnia and in Perth, Oxford and eastern Elgin Counties.
Four Counties Health Services (FCHS)

This clinic is hosted by a small community hospital in the village Newbury, 45 minutes west of London. The name ‘Four Counties’ refers to the fact that the hospital is situated near the intersection of Elgin, Kent, Lambton, and Middlesex Counties. Our clinic at FCHS serves those who live in the hamlets, villages and farms of the Four Counties area, as well as in the nearby urban communities of Chatham and Wallaceburg.
The FCHS clinic provides access to specialty respiratory care for those who otherwise would need to travel to London or Windsor to see a respirologist. Dr. Farquhar, whose teenage summer job as a farm hand left him with a lifelong affinity for the rural and farming life, sees patients at FCHS one to two Fridays per month.
London Inter-Community Health Centre (LIHC)

The LIHC is an inner-city primary care clinic, located at the corner of Dundas and Adelaide Streets, which serves a number of vulnerable populations, including people who are unhoused, living with addiction, seeking refuge or asylum, and/or living at significant socioeconomic disadvantage. Dr. Farquhar sees patients in this clinic – LIHC clients with lung conditions who would find it a significant challenge to make their way to one of our other practice sites – one day every three months.
Home visits

Dr. Farquhar sees selected patients, with their permission, in their homes, usually on a Saturday afternoon, one or two days per month. Home visits provide Dr. Farquhar the opportunity to maintain in-person contact with people who are homebound by severe mobility challenges, or have reached the end-stages of their chronic respiratory condition. A home visit is a special privilege that allows Dr. Farquhar to gain deeper insight into how patients manage from day to day in their own micro-environments, and whether their supports and resources are sufficient to meet their needs.
Virtual care

The widespread adoption of virtual care is one of many lasting innovations that grew out of the challenges faced by our health care system during the COVID pandemic. Dr. Farquhar offers virtual follow-up care, by internet-based video-conference platform, or telephone, to patients with mobility challenges or limited access to transportation, and to those who live outside London and/or do not require on-site physical examination or diagnostic testing during a follow-up visit.
Although in selected circumstances, an initial consultation visit can be conducted by video-conference, an in-person appointment is always preferred for your first meeting with Dr. Farquhar. Our ‘virtual care clinic’ is held on Tuesdays, with occasional virtual visits scheduled on Wednesdays or Fridays.
