Hi Ilan, when
I say expect to be surveiled, I mean someone will be sent to your home to see you are not shovelling snow when you are saying you are totally disabled. In my disability file, there were pictures of my condo building and notes that twice they came and did not see me (I was in bed).
A good blog to read about disability, even if it's US Content, is very helpfull, google Linda Nee disability blog.
I was not sent to see their own dr but they sent me for a functional capacity assessment by a physio, for 2days. It's was difficult and after the first day, it felt like I was run over by a truck. The physio disregarded that and felt I was deconditionned and that I should have aggressive physio then return to work.
It didn't quite go like that.
A 2 consecutive days exercise test could prove useful if you have ME to prove disability. I don't know your specifics, but speaking with your provincial association could be helpful. There is usually people within the association who is knowledgeable with disability insurance.
