I am on disability in Ont. for major depression and panic attacks. My phychiatrist suggested it when I was 18, I am 28 now. I believe it took quite a while before I got any approval or support - maybe 9 months or a year. Sorry I can't be more specific... my memory sucks! I didn't really have to do much - my doc took care of everything. I know I was lucky for that!
Good luck and hang in there!
They can be very slow in the processing.
