Is there a Ds clinic/hospital close to Ottawa/Kingston

I am reading more about DS and I am thinking that this may be a better surgery than the RNY as you are not so restricted but can still lose the weight quickly, Am I right?  Does anyone know how much it costs for this surgery is not approved by Ohip?  I have a low BMI but am really considering all my options before my BMI gets higher and I feel worse.
