Need referral for RNY revision in Ontario

I can see from reading here it can be done.  Does anyone have any referrals?   I had surgery in 2000...and would like a revision (all the weight is back). The Humber surgeon I was assigned to said he can't help so I'm hoping someone can.   TIA.  

Revisions are few and far between here in Ontario. If you get some info, please send it my way! Good luck!
