Dropped out, What now?

I dropped out about two years ago mostly because I was put in a lower educational level class because I skipped school quite often, So because I skipped school they determined I had retard level education. I don't want to go back to high school i highly doubt they would let me if i asked, So what do i do now? I could try to get a GED but what does a GED really do. Is a GED as good a HS Diploma? If not then how would i go about earning my HS Diploma without actually going back to high school. I assume this all depends on my location. Well i live in Ontario, Canada. Any information is appreciated. Thank you.
