(Remember the exchange rate, too - at the time I went, Canada's dollar was actually worth slightly more than the US dollar, so it cost me *more* than Brassard's list price [argh]. But generally both the Thai and Canadian currency is worth less, meaning there'll be an exchange-rate "discount" for US customers.)
Brassard's cost is all-inclusive : 1 night in the B&B, 2-3 day hospital stay, 7-8 days in the recovery residence, 24/7 nursing care and food provided in both, and all supplies including medications. There's also a car to pick you up at the airport/bus/train station and a shuttle from the B&B to the hospital. The only costs not included will be travel to and from Montreal and a place for anyone to stay if they come with you.
Since I used a fortune in KY and disposable underpants alone, don't underestimate what the "all supplies" part is worth.
