I'm from Manitoba and I didn't get any help from the government (except a tax refund of approx 3% of the cost of trip and treatment) or from insurance. Really clarify with your Doctor at home about the type of follow-up they will provide. In Manitoba the follow-up is only if your GP thinks you are having problems. The radiologists don't acknowledge restenosis or scarring down of the vein. The only thing they report is complete occlusions and then they aren't prepared to deal with the issue.
Things have not changed in Canada (not Manitoba for sure) in the last 2 - 3 years.
Good luck and I fully believe that CCSVI is real and if treated properly can make a real difference in your disease.
