Our History

The Ontario Bariatric Network (OBN) was established in 2009 as part of the Ontario Bariatric Services Strategy initiated by the Ministry of Health and Long-Term Care of Ontario. 

The Ministry of Health and Long-Term Care (MOHLTC) had a vision to develop the Provincial Bariatric Program to make treatment more accessible, reduce the number of people suffering from obesity and obesity related diseases, seeking out of province treatment and improve patient flow.  To achieve this vision, the MOHLTC approached Dr. Mehran Anvari, a renowned general surgeon with provincial leadership in bariatrics and program development, to lead this exciting project as the provincial Clinical Lead and Chair of the Ontario Bariatric Network.
