I'm trying to get for info about my greatgrand father by sss, passed away?

I'm trying to get for info about my great grand father, who passed away. I have his sss number. I was wondering how to get more info about him?
Another thing I saw some info about him on those ancestry.com but it didn't list race.
How do I get a copy of his certificate?
