Jan 24/72 North York

I am looking for my birth sibling, both of us were born at the same hospital in Ontario. I was born in 1977. My mother lives in Ontario and I live with my father. My mother told my father that the baby died, he does not believe it. I do not believe that my sibling would know anything about the father. I believe my sibling was born between 1972 - 1974 at North York General Hospital. Do you know anything about the adoption, or parents? I tried everything I can to try to find my sibbling. If you have any information on your adoption, the mothers last name, or any clues. Please contact me. I know a lot more information and I have many pictures of my mother and father. Thank You
