I don't know anything about surgery in Canada. Maybe if you post this on the Saskatchewan forum, you could get some valid input.
In the USA, band surgery generally costs about $14,000. In Mexico, maybe half that.
In deciding your budget for surgery, be sure to keep in mind that band surgery is not a quick-stop procedure like, say, gall bladder surgery (you see the surgeon once before surgery, on the day of surgery, and once afterward. Band surgery requires frequent follow-up visits and fills, for an indefinite amount of time. Some surgeons include a year's worth of follow-up visits in their up-front fee. That's fine, but you need to find out what follow-up visits and fills will cost you after the first year. In my part of the USA, fills cost about $300 when done in the surgeon's office, and 3-4 times more when done under fluoro.
