OBN Bariatric Centres

The Ontario Bariatric Network (OBN) is a collaborative network consisting of 11 Bariatric Centres across Ontario with interdisciplinary teams of bariatric experts that provide comprehensive medical and surgical bariatric services. The 11 Bariatric Centres across Ontario include 10 Bariatric Centres of Excellence (BCoEs) and 1 Regional Assessment and Treatment Centres (RATCs).

A Bariatric Centre of Excellence is an organization with a team of experts promoting the collaboration and use of best practices around the care of people suffering with obesity and obesity related diseases.  

Certain criteria must first exist in order for a centre to qualify as a BCoE:

  • Full acute care and inpatient facility
  • ICU availability
  • 24-hour emergency department and 24-hour surgical coverage
  • Oximetry beds for postop care with respiratory technician availability
  • At least 2 laparoscopic bariatric surgeons each performing minimum of 50 cases per year
  • Minimum of 120 bariatric cases per year
  • Multi-disciplinary clinic for preoperative and postoperative care
  • Medical bariatric support for clinic and inpatient care
  • Psychiatry support for preoperative and postoperative assessment (if necessary)

RATCs do not provide surgeries at their location. RATCs partner with a BCoE to provide pre-operative and post-operative care.
