Bariatric surgery referral process (Requires provincial referral)

To refer your patient for bariatric surgery, you must complete the referral form on the Bariatric Registry. Your patient will be matched to a Bariatric Centre of Excellence or Regional Assessment and Treatment Centre; this is based on the patient’s postal code. For more detailed information, visit the Ontario Bariatric Network website.

Our office will contact your patient directly to invite them to a group information session. Your patient will then meet with one of our physicians, nurse practitioners or registered nurses to determine if your patient is a surgical candidate. For more information about the surgical pathway.
