Recent news story for a lady with cancer in the abdomen (I think maybe tied to colon?) . Doctors refused to operate and she ended up going to the US and pay 100k for the operation because she wanted to try even though chances were rather low that she would survive / get better. Still she felt that she should have the opportunity to try regardless.

Edit: https://www.cbc.ca/news/canada/windsor/windsor-essex-cancer-surgery-pay-out-of-pocket-1.6604129 it was appendix cancer.

The doctor claims that he sees quite a few Canadian patients looking to get the treatment and for whatever reason Canadian doctors either are not allowed or refuse to do the surgery.
