Duodenal Switch in Ontario

To find out if you qualify for bariatric surgery in Ontario see the list of Bariatric Surgery Criteria below.

To start the process you need a doctor to register you in the Ontario Bariatric Registery . Once registered you will be assessed by a surgeon from your assigned Regional Assessment and Treatment Centre. To our knowledge only one surgeon in Ontario is performing Duodenal Switch (DS) surgery. If the surgeon you have been assigned to does not, at your assessment you can ask for a referral to Dr. Dennis Hong at St. Joseph’s Health Centre in Hamilton to be evaluated for the DS.

Remember, if you do not meet the requirements for Duodenal Switch surgery coverage in Ontario you have the option to self-pay. There is a surgeon in Quebec, Dr. Gagner, and surgeons in the US and internationally that provide these services. Please make sure you thoroughly research your surgeon’s credentials and experience.
