Jen,
Canada has a different medical care system than we do. The USA is not the place to be if you are a sick person, bottom line. If you are a young and sick American and have some portability I would suggest moving to Canada or Europe, although I am not sure how good the actual quality of the medical care is in the EU. I must say, all of my medical providers are top notch. I had thyroid cancer surgery as well in 2015 and my surgeon and endocronologist and PCP at Yale are all top notch specialists.
