These sick people there need to move out permanently to go live far away from the province and see if they get better. If it's prion disease, they probably won't reliably get better by moving alone. They also should do private testing for heavy metals.
The Canadian government looks to have both failed and abandoned its people. It could have tested them, profiled the disease, understood its cause, and tried treatments, but it looks to just not care.
In the simple case, if it's just a neurotoxin, it might show signs of getting better upon moving out.
