Could it be that that the circumstance of your ortho saying 'no one would touch you', he was referring to the National Health System in CANADA as to free or low cost help where they might have some preclusion for that on the basis of the 'bite bieng right', like a preclusion if they feel it's being pursued for aesthetics?
If that's the case and you want the Canadian system to do the jaw advancement, maybe consider asking your primary care doctor for a SLEEP STUDY to confirm possible apnea.
The other option, to the best of my knowledge, is the self pay option which is very much on the expensive side. Some people on the board, travel to Europe or US to 'Big Name' doctors in US when a concern is 'for aesthetics' or 'preventative sleep apnea' via the jaw advancement.
As mod, I hesitate to openly name them though as to avoid appearance of giving a recommendation. But there are others on here who have sought out the 'Big Names' in the event you are considering the self pay option.
