BC Resident who had an emergency surgery in the US, just MSP coverage. How boned am I?

A day trip for shopping turned into a disaster about 45 days ago in Bellingham.

Had to spend 2 nights in intensive care after surgery. Total bill: $115K USD.

I stupidly didn't purchase supplemental insurance since it was only for a few hours.

Will MSP help at all outside of the $75Cdn/day? I'm about to file for the paperwork and just wondering how much I should be preparing for out of pocket. I don't have enough savings to cover that so not sure what next steps are. Thanks for any tips.
