Looking for my birth mother (Oshawa, ON, Canada)

I am looking for my birth mother Teralee Ann Harper (ne Pitt). Last name may have changed. Known to have lived on Athol St E in Oshawa, Ontario back in 1984. She would be turning 63 this year and was born in Calgary, Alberta on Aug 17 1950. I was born to her, a baby boy, on June 9th 1984 at the Oshawa General Hospital. I was named by my adoptive parents. My adoption was private and done through the law office of J Paul Fletcher in Port Perry, ON. Any info would be helpful, more or less looking for anything medical as I now am married and have 4 kids of my own. tyler@runnrat.com T
