Centre of Excellence in Adolescent Severe Obesity

Obesity is recognized as chronic disease that affects over 10% of youth in Canada. As a chronic illness, obesity can affect other systems in the body and eventually lead to death when it is not managed.  Obesity is a complex condition that is influenced by a number of environmental, social, familial, and personal factors.  Therefore ‘quick fix’ approaches often result in only temporary weight loss, and is detrimental to the overall mental and physical health of the individual living with obesity.  A long-term, integrated treatment and management strategy is the best way to promote overall health and well-being.

Assessment Clinic

Once referred to the program, the team will review the information provided to ensure the patient is eligible to be seen.  If so, the Administrative Assistant will contact the family to schedule a baseline assessment in order to better understand the needs of the patient.  The assessment will include blood tests, an electrocardiogram (captures heart rate and rhythm), pulmonary function tests (how well the lungs work), exercise testing, lifestyle questionnaires, and meeting with the different team members including the physician for a physical examination. The assessment may take up to several different visits to complete.  After the initial assessment, a follow-up appointment will be scheduled to share the findings with the family and patient and determine the most appropriate next steps. In addition, you may be invited to participate in one of our on-going research projects.

Our Team

Team members


Our specialists are often pursuing research projects.  Families may be approached about participation in research aimed at improving our knowledge and treatment of patients living with severe obesity.  Participation in research is not required and refusal to be part of a study will not affect treatment in any way.


We are continually working to enhance our partnerships with credible community organizations willing and able to provide additional support services to patients living with Obesity.
